The Exchange of Heat

There is often a need to cool, heat and or dehumidify air and this need can be met with a heat exchanger coil. There are several different types available here at HECAS and so we have created a quick guide to help you make the right choice.

Heat exchange coils are found in many different types of machinery and environments right across industry, from hospitals and shopping centres to offices and laboratories. Without them, key industry processes could not happen including drying, blast freezing and material temperature control.

The HECAS selection of coil options is designed to be comprehensive and efficient, with further bespoke optimisation available to exactly suit your unique requirements. Our heat exchanger coil options include:

Water Coils are designed to transfer heat energy between air and water, in the fastest, safest and most efficient way possible. Both heating and cooling coils fall into this category.

Heating Coils: take energy from hot water to an airstream

Cooling Coils: take energy from a hot airstream and add it to cold water

Casing options are economy, standard, enclosed and unitary.

Steam coils transfer heat energy from steam into air in a highly efficient manner. The energy is provided by the latent heat of vapourisation from the steam as its phase changes from vapour to condensate. Casing options are standard, enclosed and unitary.

Refrigerant coils are designed to transfer heat quickly between the air and refrigerant. Both condenser and evaporator coils fall into this category.

Condenser coils: transfer heat from refrigerant to air as refrigerant changes phase from vapour to liquid

Evaporator coils: transfer heat from air to refrigerant as phase changes from liquid to vapour

Casing options are standard, enclosed and unitary.

Run-around coils are heat recovery systems comprising two coil heat exchangers in an  integral unit. The matched pair of coils are connected by a continuous loop containing the heat exchange medium. Medium flows between the two coils are controlled accurately at the prescribed rate against total system resistance with the reclaim pump pack. Casing options are: standard, enclosed and unitary.
