ThermoCooler HP

Integrated reversible heat pump with stepless cooling and heating power

The reversible ThermoCooler HP heat pump can be integrated in our Envistar Top and Envistar Flex units.

Why choose ThermoCooler HP?

ThermoCooler HP is the optimal integrated reversible heat pump for the Envistar series.

All parts of the reversible heat pump are incorporated in a module section, which is located in the air handling unit. This means that you receive a total solution for heating ventilation air and comfort cooling in one unit. Since everything is integrated in the air handling unit, there is no need for heating coils, run-around coils or outdoor cooling installations. The installation is complete, CE-marked and always tested in our test facility before delivery.

A unit with integrated reversible heat pump is more energy efficient than a traditional cooling installation with external cooling unit and heating coil.

Stepless control

In some buildings, the air flow varies greatly, but there is still a requirement for close control of the supply air temperature. ThermoCooler HP meets the requirements through stepless control of the cooling and heating power via a frequency inverter.

The benefits of stepless control are:

low minimal air flow
optimal variable performance

Save floor space with top connection!

To achieve a comfortable indoor climate, air handling units are often installed in combination with cooling units on the roof. By integrating ThermoCooler HP, the roof can instead be used for something much more pleasant than equipment.

ThermoCooler HP is also available for our Envistar Top series, which saves floor space. An example from a recent construction shows that as much as 20 m² of floor space could be saved when installing three top-connected units compared to one end-connected unit.

Potential exists to significantly reduce the total construction cost or to create more leasable space.
