Chillers

Chillers are the whales of the air conditioning industry. Big and solid, they can go on forever. Their ability to provide an enormous amount of kilowatt cooling at energy efficiencies makes them the most installed units for large plant. 

Chillers are essentially found in large office towers, hospitals, hotels, arenas and other large spaces to be cooled at one location. Tecair installs and service chillers nationally with brands such as Fujitsu, Powerpaxx, Rhoss and others on our books.

Chillers, while extremely expensive to purchase and install, do last from 20 to 25 years with proper maintenance. The unit’s engineering often includes bearingless propellers and other maintenance saving measures that make these units extremely efficient, given the amount of cooling capacity they are able to turn out.

Most chiller maintenance, other than monitoring, is in the annual overhaul which requires a two-day shutdown of the unit for extensive cleaning and maintenance. Chiller maintenance is typically conducted during the winter months so there is little disruption to cooling requirements. Chillers are a relatively low maintenance piece of equipment and highly efficient.

 Always located alongside chiller systems are typically a number of high capacity pumps which pump the cooled water to other parts of the building. In just about all instances there is backup capacity, with additional pumps waiting and ready to go. The chilled water, once distributed to locations throughout the building, is then pumped through a coil. A fan throws air across the coil, which then cools the air for the occupants of that area. The now warmed water is then pump back up, usually to a water cooling tower on the roof of the building where it is pre-cooled before being then pumped back to the chiller for a further temperature reduction. This circuit is closed and does not typically require additional water to function.
