Chilled water is used as coolant inside tubes for the chilled water coil. The chilled water coils dehumidify the moist air that flows over the face area of the heat exchanger. To maintain higher rate of heat transfer, air and water normally follows as counter flow arrangement.
Chilled Water Coil
Latent heat of condensation of steam is utilized by steam heating coil to heat the outside and recirculating air. Heat is rejected to air when the steam and air comes in contact. STEM steam coils are designed to minimize the water hammering effect and maximize the heat transfer effect.
Steam Coil
Condenser is a major system component of a refrigeration system. Condenser coils uses air blown through the face area of heat exchanger to extract heat from refrigeration flowing in tubes. Subcooling region is added to condenser coil to ensure the heat is removed adequately before leaving the condenser.
Condenser Coil
In a DX coil, heat is absorbed by refrigeration in order to cool and dehumidify the air flown through the heat exchanger. In general, refrigerant is fed through distributor first in order to distribute the refrigerant evenly to the circuits to maximize the heat transfer rate.
DX / Evaporator Coils
A hot water coil is similar compared to chilled water coil, the only difference is hot water is used as the medium inside the tubes. Hot water coils are used to heat up the air passing through the heat exchanger and they generally come within the range of 1 row – 2 row.
Hot Water/ Booster Coils
Can be used in most clean room application. With a variety of materials allows us to design and fabricate the appropriate dry coil to meet your unique requirement. Fin spacing, circuiting and fin design can all be varied to assure your performance, air and water pressure drop limitations are maintained.
Dry Coils
Water cooled condenser is used to remove heat from refrigerant. Water source is usually from the cooling tower recirculating water or lake water if the HVAC unit is near the natural water source. Water flows inside the copper tube while refrigerant flows in between the steel pipe and the copper tube in a counter flow arrangement.
