Evaporator Coils

An evaporator coil is one of the most important components of an HVAC and refrigeration system. The function of the evaporator coil is to extract indoor heat from the air and transfer it to the refrigerant. A refrigerant runs through its copper tubing that removes heat from the air.

Our evaporator coils are fin and tube type heat exchangers made up of highest quality raw materials. The tubes are made up of aluminum or copper and fins made up of aluminum.

Fins increase the overall surface area for heat exchange, thus drastically improves the heat conducting efficiency. Based on desired performance and application, we also offer anticorrosion coating for fins and tin coating for copper tubes, to make our products long lasting.

Headers and end plates used in coils are manufactured in our own press shop and header manufacturing unit to ensure highest quality.

Our evaporator coils meet the required international products and quality standards like UL certifications.

Our raw materials (copper tubes and metal sheets) and semi-finished & finished products (aluminum fins, copper headers and fittings, end plates, evaporator coils) are tested under our Standard Operating Process (SOP) at all the key stages of production.

Our design, production and testing team use their expertise to match the technical specifications set by our customers in terms of material, design, quality and performance.

Evaporator coils are used in heating equipment, ventilation equipment, and cooling or air-conditioning equipment used in domestic, commercial and industrial HVAC systems to control the temperature, humidity, and purity of the air.

We have a wide range of standard products and we are also capable of manufacturing customized evaporator coils in any dimension and capacity for our client’s specific need. And YES! We do this for you within the defined timeline and quality parameters!
