HVAC Coils
Heat Exchanger Coils are required in AHU to provide heating, cooling, or both to change the supply air temperature, and humidity level depending on the location and the application. Such conditioning is provided by heat exchanger coil(s) within the air handling unit air stream, such coils may be direct or indirect in relation to the medium providing the heating or cooling effect. We Design, Fabricate and Supply various Heat Exchanger Coils for Project Base, OEM and MRO market. Our products are fabricate directly from factory and certified by AHRI. We are capable to fabricate coils with dimension of 2.5m Height (not limited) and 12m Length. We made:

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

Our rated heat pipe coupled with our AHRI certified heat transfer coil, performance is guaranteed and able to provide significant improvements in operational effectiveness.

Heat Pipes

Stainless steel coil is used for heating/cooling application in a very corrosive environment either acidic or alkaline. It is also widely used to withstand the corrosive nature of some synthetic oils and refrigerants flowing in the tubes.

Stainless Steel Coil

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.

Tube in Tube Condenser

Shell and tube heat exchanger is commonly used for high-pressure applications and high cooling requirements. The heat exchange is between cooling water and hot refrigerant or reverse cycle and they are arranged in counter flow arrangement.
