A good maintenance regime can go a long way in minimizing operating costs while increasing the life of your chiller systems. Industry statistics indicate that chillers regularly maintained can serve up to 20 years or more, while problems created by the absence of maintenance cause failure within a decade. Besides, proper and regular maintenance can lead to energy savings of at least 10 to 15, which is a significant figure in an area where energy is expensive. 

Here, we highlight effective techniques for maintaining commercial chillers, address common breakdowns, and highlight the essence of professional service providers in the UAE for maintenance or repair. Adhering to these guidelines would only allow businesses to enjoy the peak performance operation of their chillers for comfortable living in the environment.

Understanding Commercial Chillers

Before that, knowing the commercial chiller and how it works is essential. Commercial chillers remove heat from a liquid through vapor-compression or absorption refrigeration cycles and circulate this chilled liquid within a building or process to absorb the heat. The process is very important in the following applications:

Air Conditioning: Comforting indoor environments for people in offices, hotels, and shopping malls.

Industrial Processes: Cooling the machinery or products in a manufacturing facility.

Food Preservation: Keeping perishables below safe temperatures in supermarkets and restaurants.

Types of Commercial Chillers

Several types of commercial chillers are most common in the UAE.

Air-Cooled Chillers: Refrigerants are cooled by air in these units, making them best suited for small applications or where water is available.

Water-Cooled Chillers: These are more efficient than air-cooled units as they transfer the heat to water supplied by cooling towers.

Absorption Chillers: These systems cool with heat sources instead of electricity, like natural gas; hence, they are most economical and used in industries with heavy applications.

Before implementing any form of maintenance practices, understanding the kind of chiller you have is of great importance.
