Things to Consider When Choosing an OEM Chiller Manufacturer


Regardless of what you use it for, your OEM chiller is one of the most important pieces of equipment your business can own. That makes selecting the right manufacturer imperative. As you look at OEM chiller manufacturers, here are a few characteristics you should insist upon.

State of the Art Production

Chiller technology has been pretty steady throughout the years, but production processes have been constantly improving. Because of that, you need to insist that your OEM chiller be made by a manufacturer who employs the latest in production equipment, processes and protocols. They need to be highly automated and that automation must be able to produce quality checks on a regular and on a scheduled basis. It also helps if manufacturing chillers is a major part of their business, if not the only product they produce.

Load Run Testing, QA, and QC

It is mentioned above but it cannot be understated. Quality assurance and quality control are key components to be sure OEM chillers will withstand rigorous use. Additionally, the manufacturer you choose has to be able to perform under load. That means they must have production machines that are continuously tested while performing under load. They also need to have continuous improvement processes that enhance the production of chillers. Finally, they need to be able to perform quality control and catch any errors before the product is shipped to you.

While a physical tour may not be possible, each of the above has to be documented. You should ask to see not just the processes to go into their quality testing, but also results from several production runs. You should also insist on random quality assurance testing. If they do random testing at the quality assurance or control level, you should ask to see the results.

Technology Capabilities

You also need your OEM chiller manufacturer to utilize the latest in production technology. Part of this should include being able to show you in 3D what any design concept would look like when carried to fruition. The production processes should also include quality check capabilities, scheduling, and monitoring of any particular piece of equipment and where it is in the production process.

As you review OEM chiller manufacturers, it is important that you insist upon certain qualities. The above guidelines can help make sure that you get the chiller you want and that it will be able to serve you for years to come.

Commonly Overlooked Maintenance Areas of Chillers

Laser chillers

Maintenance, preventative and needed, is a key aspect to any precision machinery’s lifecycle. Production schedules, client demands, and time constraints can often lead to overlooking aspects of maintenance routines and that can lead to breakdowns in the overall performance of the equipment as well as a shortening of its life. Following all the maintenance recommendations of laser chillers manufacturers, for example, is extremely time-consuming, if important. The following are areas of chiller maintenance that are often skipped or overlooked.

Optic Recalibration

Every time an industrial laser chiller has maintenance done on it, the optics should be reset to OEM specifications. This is because out of compliance optics can affect the quality of beam and mode, cutting performance and even the lifespan of the optics. To recalibrate the optics in a chiller, follow the manufacturer’s guidance and any guides that are included on the equipment.

Air Flow

Just about every laser uses an assist gas, which exits via the cutting nozzle and helps the laser achieve a cleaner cut. The most common gasses used are oxygen, nitrogen and shop air. For these gases to work effectively, the lines have to be clean in order for the system to maintain proper air pressure and filtration. All lines should be checked and the compressed air source should be tested regularly.

Chiller Temperature

The chillers for lasers have a temperature gauge that has to be monitored whenever the machine is in use. Variable temperatures could affect the machine’s performance or reflect a larger issue like refrigerant leaks or similar problems. In the most extreme case, temperature variations can cause resonator damage. Sensors will detect most temperature variations, but it needs to be continually monitored.

Cleanliness Equals Functionality

Keeping the chiller and associated equipment clear of dust, dirt and debris is key to it operating efficiently and effectively. A dirty machine can cause material shifts, which result in handling problems. In extreme cases, buildup can cause scrap drawers and slugs to become jammed. A neglected machine also poses a danger for thermite buildup, which can ignite and cause extensive damage to the equipment as well as pose a threat to the employee.

The maintenance guidelines for laser chillers manufacturers are pretty specific, but the key to all of this is diligence on the part of the employee. If the machine is kept in good order, it will provide accurate cutting for its lifespan.

Why Are Medical Chillers Important for Patient Care?


Medical equipment and supplies are highly sensitive to temperature changes, which is why hospitals and other medical facilities must have dedicated areas to store them. Hospital apparatuses such as those used in laboratories, blood cooling systems, MRI and CT scanners, and cancer treatment and applications all need the right temperature to be effective. Without medical process chillers, they will be prone to damage and the cost of maintaining equipment will go up significantly.

Hospital Equipment Is Vital

Hospital equipment is vital for operations and patient diagnosis. When a machine is out of order, it increases the risk of misdiagnosis and patient care. For example, MRI is an essential piece of equipment for imaging for all types of patients. Doctors can see things internally without the need for surgery.

When an MRI scanner is unavailable, it puts patients’ safety in peril, especially those who need stat imaging procedures like critical vehicular accident patients, and more. Time is essential when providing proper treatment and care. Otherwise, patients may need to go elsewhere for diagnosis and treatment. For this reason, hospitals must invest in medical chillers for MRI to maintain their equipment and to serve their clients well.

Medical Chillers Increase the Longevity of Hospital Equipment

A working cooling system will ensure that professionals can use different expensive equipment to provide an appropriate procedure and care for a long time. Health care workers use different modalities to help map out every patient’s disease process. With the help of specialized equipment, they can learn about a client’s condition, and come up with the most suitable care for the patient.  Besides, the longer these apparatuses work optimally, the more profitable a hospital becomes.

Providing care is not limited to bedside procedures. Medical equipment also plays a role in making sure that patients get the best possible care in a hospital. Doctors and nurses also base their patient care interventions on measurable data from the use of medical equipment.

Many air-cooled chiller application systems also come with backup systems that fulfill the standards for medical cooling. Moreover, highly-specialized systems and equipment must employ specifically-trained staff that can troubleshoot the equipment anytime. If you're a hospital or a laboratory owner, make sure to invest in a good cooling system to protect your equipment and maintain the integrity of your work.

How Helium Is Used in MRI Machines


An MRI of your body uses a computer, radio waves, and a magnetic field to generate photos of the inside of your body. These images are used to assist with diagnosis and treatment for many conditions within your abdomen, chest, and pelvis. Here's how helium is used in MRI machines.

What Is an MRI Machine?

MRI, also known as magnetic resonance imaging, is a method that uses radio waves and a magnetic field to generate comprehensive images of your body's tissues and organs. Many MRI machines are large, tube-shaped magnets. Once you lay down inside of an MRI machine, the magnetic field briefly realigns hydrogen atoms in your body. The aligned atoms deliver very low signals caused by the radio waves and they are used to generate cross-sectional MRI images.

Why an MRI Is Done

An MRI is a non-invasive approach to examine your tissues, organs, and skeletal system. The images that are generated can be used to diagnose multiple issues and to monitor how well your body is responding to treatment. When an MRI is done on the brain and spinal cord, it looks for brain injury, cancer, spinal cord injuries, stroke, and multiple sclerosis. When an MRI is done on the heart and blood vessels, it looks for heart disease, blocked blood vessels, issues with the structure of your heart, and damage caused from a heart attack.

MRI Machine Chiller

An MRI cooling system ensures that the scanners function at the highest levels. There are two methods available for cooling and that's air and water-cooled chillers. The MRI machine chiller is in charge of removing heat from the MRI scanner. The MRI scanner chiller uses different means of transferring the heat. If your establishment does not have a dependable water source, then an air-cooled chiller is your only option.

How an MRI Machine Uses Helium

An MRI machine is comprised of wires, coils, and a magnet. Helium is used to cool down the superconductive magnet's coil in the MRI scanners. The temperatures must be below 10 Kelvin. Superconductivity allows an electrical current to circulate through an electrical conductor without generating electrical hindrance. The machine needs an element so that it can maintain a cold temperature. Helium is the only source that is cold enough to support superconductivity in metals. The typical MRI machine uses 1,700 liters of helium.

Important Aspects to Consider before Buying an Industrial Chiller


The types of uses for industrial cooling systems differ in each industry and the chillers have various shapes and sizes. The type of chiller that you use depends on your operational needs and other factors. Knowing the appropriate information can help you choose the right chiller for your operation. There are important aspects to consider before purchasing an industrial chiller.

What Is an Industrial Chiller?

An industrial chiller is a refrigeration system that dehumidifies air or cools fluid in industrial or commercial businesses. The chiller uses an absorption cycle or vapor compression to cool. The chillers are used for multiple purposes such as chemicals, food and beverage, and machine tools.

How Does a Chiller Work?

In many cooling processes, a pumping system circulates cool water from the chiller to the process. There are two types of condensers developed by industrial chiller manufacturers, which are air-cooled and water-cooled. Air-cooled condensers use moving air to cool and condense hot refrigerant gas back into a liquid. With water-cooled condensers, water that comes from the cooling tower condenses the refrigerant.

Factors to Consider

Size of Business:

The size of the business is a determining factor for the capacity of the industrial chiller systems to use in it. Some businesses produce substantial amounts, so they call for larger equipment than others. Food industry businesses require the chilling of mass quantities of food. They utilize large-sized chillers that are capable of handling bulk loads rather than using smaller chillers.

Type of Industry:

There are industries such as meat, electronic, and medical that need to use various types of chillers. These industries have different products and services and their operations are varied. The type of industry determines what chillers will meet their needs. With printing industries, chillers are used to cool the printer rollers and the paper, but in the plastic industries, chillers are used to cool hot plastic.

The Chilling Process:

The chilling process is different in each industry. Prior to purchasing a chiller, you must figure out what equipment needs to be cooled, how much water pressure is required, and the amount of flow throughout the process. Your operation may need an air chiller, water chiller, or portable chiller.

How to Make Your Chiller System Last Long


Many businesses rely on OEM chillers to produce, store and sell perishable items continuously. However, operating and maintaining your equipment can be tricky especially since they're on 24/7. Many factors affect your chiller system’s performance, and if you want to get the value that you paid for it, then there are ways to get it to work efficiently and make it last longer.

Keep a Daily Chiller Diary for Every Shift

Record your chiller’s operating conditions every day or work shift to see if it’s working in top shape. Temperature, fluid levels, and other factors are important determinants of your chiller’s performance and must be in your daily report. If you see a trend with the values that you record, then expect some issues with your machine.

Clean Regularly

Dirt can decrease the performance of your OEM chiller, so it is essential to clean it daily. Also, consistent and day-to-day cleans will help your chiller transfer heat efficiently. Also, watch out for the accumulation of contaminants along your chiller’s condenser tubes to ensure optimal performance.

Monitor Refrigerant

Your chiller must move refrigerant through your compressor adequately to make it cool down faster. Pay attention to leaks and increased condensation because this means that you may need to refill your coolant. Also, when the refrigerant is low, your compressor works hard double time, significantly decreasing your chiller’s efficiency and service span.

Watch out for Corrosion

Monitoring water quality can help give you an idea about your chiller’s corrosion. Pooling water can become stagnant, and breed bacteria and foul odor so treat your condenser loops for water quality regularly.

Monitor Water Flow

Maintain water flow at ideal levels within your tubings to keep your chiller working efficiently and help you save on energy. Watch out for noises and vibration which could indicate that your flow rate is decreasing. The ideal amount of flow rate is at 3FPS. Anything below or more than that can cause your chiller to break down.

Schedule regular maintenance or your chiller. Professional OEM chiller manufacturers can provide you with the right systems that you need and help you maintain and determine potential problems that you might miss upon daily inspection later on. Also, when your system is working poorly, your operations and profitability could suffer because it could result in spoilage or worse, purchase of new equipment.

Choosing the Right Laser Machine Chillers

chiller High-powered lasers produce tremendous amounts of heat. That heat can impede performance if not properly monitored. Excess heat must be removed from the system so that overheating doesn't occur, thereby damaging critical components. All types of lasers, from excimer lasers to solid-state and dye lasers, rely on liquid cooling to remove excess heat. Choosing the appropriate laser machine chillers is vital to maintaining a precise laser wavelength, keeping an optimum beam quality, and diminishing heat stress on the laser system. Here are a few things to consider when looking at laser water chillers.

Recirculating Chillers

Readily, commercially available, recirculating chillers are convenient for any laser system. As a closed-loop system, they're more environmentally friendly and cost-effective than any system that uses tap water, and they provide a constant flow to the system without any diminishing of the coolant's quality. Though keep in mind, it's important that the pressure is maintained as too much water pressure can result in vibrations in the laser head.

Liquid-to-Liquid Cooling

Transferring to facility water via a liquid-to-liquid heat exchanger, the temperature can be accurately maintained, making the liquid-to-liquid cooling system (LCS) an ideal choice for any system where high heat load, or excessive ambient temperature applications have a nearby facility where chilled water can be utilized. This is a perfect option for any laboratory with several large lasers in operation.

Ambient Cooling

An ideal alternative to refrigerated chillers where extreme accuracy in temperature control is not required, ambient cooling simply relies on the heat moving from the water circulating through the laser system and coming into contact with the outside environment. While not providing temperature stability, they are a cost-effective alternative to the more sophisticated chillers.

Cold Plates and Heat Exchangers

Important elements in liquid cooling loops, cold plates work best when combined with a recirculating chiller. Heat exchangers play an important role in many types of cooling systems. Oftentimes, manufacturers would rather obtain heat exchangers themselves so they can connect them to their own pumps and reservoirs.

To keep high-powered lasers operating at peak performance, they require cooling. The beam quality, the precision of the laser's wavelength, and the laser's high-output efficiency often require the finest in machine chillers, so you'll want to be sure to choose the right one.

Different Types of Medical Process Chillers

chiller Medical equipment needs to be maintained at an optimal temperature to perform efficiently. The equipment can generate tremendous amounts of heat, so it's very important that there is machinery on hand to counteract that heat, so the equipment can run as it's intended. Medical process chillers are required to keep the equipment functioning properly. Whether you're researching Filtrine medical chillers, or Riedel medical chillers, here are some examples of medical process chillers and the challenges they will encounter.

Open Loop Chillers

Open loop chillers rely on a water source for cooling, instead of air. This means there is less energy required for operation, and they can be a smaller size since there is no fan required. Their smaller surface area makes them ideal for CT scans, and MRI machines, and makes them more conducive with the world of pharmaceuticals.

In-Line Chillers

Relying on a remote water tank and operating via a nearby pump sending fluid under pressure with an evaporator inside the chiller, in-line chillers are perfect for CT scans and any other job that requires the pump near the tank.

Drop-In Coolers

In this type of chiller, there is a controller which monitors the temperature of the fluid within the tank and regulates the temperature so that it is constant and safe. The drop-in chillers sit on top of a tank and rely on the cool fluid in an evaporator coil that is submerged within the tank and circulates throughout to maintain proper cooling.

Closed-Loop Coolers

Perfect for PET scans and x-ray machines, closed-loop coolers rely on coolant that is circulated from a tank that resides within the cooler. The coolant is transported through a sealed loop where it gives off heat before returning to the tank. A controller is on hand to maintain the appropriate temperature, and to sense if there are any variations in the coolant.

MRI machines, CT scanners, and PET scanners create surplus heat that can impede their operations and even shut them down. Medical process chillers not only keep the machinery running, but keep them running at maximum efficiency.
