Water Coils (Chilled / Hot)

Water Coils – Types and Purpose

Home >Our Products > Hvac Coils>Water Coils

Water coils are found in Air Handling Units (AHUs) and Fan Coil Units (FCUs) for cooling, heating and reheating purposes. 

Cooling/Chilled water coils are used to treat air, heat exchange and turn ambient air to cold air to cool down require spaces. For sub-zero applications, glycol will be added and mixed for anti-freeze purposes.

Hot/Heating and reheating coils are used to heat up moisture in the air to bring down relative humidity (RH) to desire range. Water coils common problems are sludge build up internally, oxidized/corroded or damaged fins causing supply temperature to raise as not able to heat exchange efficiently and this may indirectly result in affecting chiller’s efficiency too. Even at the tightest allowed space left with a small access door for a huge AHU coil replacement in some existing building, Unite Coils is capable of customising to ensure fitment and performance guarantee to revive and restore back to the first day performance and even further improve efficiency to reduce electrical consumption. 

We are expert in providing the best solutions for you.
