Heating/cooling coil

Different coil types provide a tailored solution for any large space. In addition to coils for connection to a boiler system or to a water chiller, special batteries (steam, electric heating coils) are also available.


The automatically adjustable Air-Injector reduces the temperature stratificaiton in interiors to 0.15 K per meter height, keeping heat loss through the roof to a minimum.


TopVent® are recirculation or supply air units for heating and cooling with recirculated air, mixed air or fresh air.

TopVent® TP (TopVent with Heat Pump)

The TopVent® TP unit is one of many TopVent units manufactured by Hoval. They are decentralised recirculation units intended for heating and cooling high spaces. They are equipped with an air/air heat pump system which generates both heated and chilled air for all year round operation. They utilise the energy in the ambient air for environmentally friendly heating and cooling.  TopVent® TP units have the following functions:

• Heating and cooling with heat pump
• Air distribution with adjustable Air-Injector
• Air filtration
• Recirculation operation
• Supplementary heating with electric heating coil (option)
• Supplementary heating with hot water (with connection to a hot water supply, option)

The TopTronic® C control system automatically controls each temperature zone in accordance with the customer requirements. The heat pump can be located up to 50m away from the TopVent® unit.
