Evaporator Coils

An evaporator coil is one of the most important components of a HVAC systems and industrial, commercial and transportation refrigeration systems. Mainly they are used in close control air conditioners, rooftops, showcasing, fan coils, dryers and other systems. The high-quality cooling of the working environment depends on it, which means that it is largely responsible for the durability and wear resistance of the unit. And that is why a properly selected and manufactured evaporator is the basis of the correct operation of the entire 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. Fins increase the overall surface area for heat exchange, thus drastically improves the heat conducting efficiency.

Large range of the fin space 1.15 till 8.5 mm permits us to manufacture the evaporators for practically all evaporating temperatures used in HVAC and refrigeration systems. Since condensate is formed during the operation of the evaporator, we often offer a special hydrophilic pre-coating of the fins. In this case, water droplets are carried out with the air into the cooled space, which is usually undesirable.

If the capacity of the refrigeration machine is large enough, then air evaporators are made with two or more cooling circuits. Each circuit has an independent refrigerant supply through a distributor connected to it by thin pipes – capillaries. All circuits are made so that are filled with equal amounts of refrigerant. We can unite two evaporators in one block that used often in industrial and transport applications.

For defrosting the holes may be provide for installation of electrical heaters, or a special circuit for defrosting by hot gas may be previewed.

We can manufacture bent coils with end plates, which are widely used for heat pumps in domestic and commercial applications.
