Water Chillers

What is the purpose of a water chiller?

Water chillers are needed in a variety of applications where precision and efficient cooling facilitates the smooth operation of machines. An industrial water chiller is especially beneficial to have in factories with large machinery that generates a lot of constant heat.  A water chiller works by absorbing, transferring and dissipating heat via a refrigeration cycle.

How does a water chiller work?

The essential components of a water chiller include a compressor, condenser, expansion valve and evaporator. Each of these parts work in unison to remove heat from a particular area in the following way:

• The compressor is responsible for circulating the refrigerant and convert it from low-pressure to high-pressure before it travels to the condenser
• The condenser cools the gas by transferring heat from the refrigerant to the outdoor cooling medium which is either air or water. Ultimately, the refrigerant is condensed and changes from has to liquid
• The expansion valve is what the liquid refrigerant passes through when its temperature and pressure is lowered. It is then passed onto the evaporator.
• The evaporator is where the heat exchange process takes place as the cooled liquid transitions into a subcooled vapour.

Our Capabilities

The Atlas Copco TCX & TCA ranges of chillers are specially designed for cooling water (or mixture of water and glycol) for multiple industrial purposes. The TCX4-90 series is a compact, all-in-one water chiller with an air-cooled condenser and integrated hydraulic module, with the ability to precisely control the temperature using an Elektronikon® MkV controller. The pump housing, tank and evaporator are made in stainless steel and the entire chiller is designed for easy maintenance with easily accessible safety components.

For large industrial applications the Atlas Copco TCA55-215 series offers a high level of energy efficiency and supplies complete safety for your day-to-day operations. Reliable and robust, equipped with proven scroll compressors in a twin circuit configuration, air-cooled microchannel condensers and integrated hydraulic module, it provides easy and cost-effective installation and maintenance.

For fully non-ferrous water circuits required for operations such as Medical MRI/CT scanning, we work with other leading manufacturers to offer the optimal solution for your specialist needs.  We can also advise on solutions for Laser and Biogas applications.

If you've recently installed a water chiller on your premises or are thinking about doing so, it is important to know how to maintain your equipment to ensure longetivity and the best performance. You can read our article on How to optimise the performance of your chiller for some advise on how to best care for your chiller.
