Medical Water Chiller Explained

2017-11-08

There are a variety of industrial and medical applications that require years of reliable refrigeration. The latest technology, which we specialize in at Amrta air conditionng, will ensure that your medical lab or industrial facility can achieve steady temperatures for every type of process.

With our leased Water Chiller, you can maintain constancy while also being able to customize the temperature of each process through an easy to configure computerized dashboard. We thought it would be a good idea here to explain how a recirculating chiller works, especially to help a company in need of chiller leasing to keep their processes constant.

We believe that our clients should be able to source chillers of the highest quality without paying too much for electricity and water.

Exploring the Recirculating Water Chiller
A recirculating chiller typically runs on a pump, such as a centrifugal pump. It works in a cooling loop, which begins with the compressor, continues with the condenser, moves to the expansion valve, and concludes with the evaporator. After the evaporation process is complete, the cooling loop begins again with the condenser.

Each component in a recirculating chiller depends on the integrity of all parts within the unit. For example, if there is a blockage within the unit, then it will not function according to its design, and the temperatures that it provides for medical or industrial large processes will not be consistent.

You want to lease a Glycol Water Chiller unit with a recirculating pump containing free flowing liquids and gases that will be easy to service throughout its lifetime. Remember, any variation in the temperature provided by a medical chiller can potentially compromise the quality of what the process is producing (i.e. human tissues or pharmaceutical liquids to be used in human treatments), processing, or storing.

In a medical lab, for example, the failure to store human materials or materials to be used in human patients at the correct temperature could be disastrous.

How Does the Cooling Path Look in Your Application?
When it comes to choosing medical water chillers, we encourage you to first consider the types of heat (albeit mechanical, chemical, radiation) within the system that could affect the temperature of what must be cooled.

For example, you may have a liquid that needs to be maintained at a constant temperature a few degrees above freezing, but it becomes warmer due to heat buildup within its housing unit. We could help you choose the right equipment to create a closed loop system which provides a cooling liquid around the container.

This keeps the liquid within the unit cool (at a preferred temperature) and ensures that excess heat is pumped away by the cooling unit and released into the air through evaporation. Other units may include a cooling coil that is present within the liquid that must be cooled, ensuring that the contents never exceed the desired temperature.

Consideration of Waste Heat
It`s important to keep in mind that most medical chillers are going to contain chemicals that are regulated by the Environmental Protection Agency. The refrigerant that is present within your chiller may be one containing a CFC, which must, of course, be disposed of in a manner that does not harm the environment.

Another by product of any chilling process, whether you use a recirculating chiller or not, is waste heat. The heat that is released through the evaporation process must be pumped out of the building through a safe method.

For example, you don`t want excess heat to cause problems with cooling or refrigeration of materials in other parts of the industrial facility or medical lab.
