HRW-Units

Design of HRW-units – units provided with high-efficiency sorption wheel
The standard HRW-units include the following components:

•                      Supply filter class F7
•                      Extract filter class G4
•                      High-efficiency sorption wheel
•                      High-efficiency EC technology ventilators, electronically controlled direct current engine
•                      Fully integrated automatic

Constructions and options for the HRW-units with sorption wheel
The HRW-units are available in four constructions:

•                      HRW standard, air flow from 3,000 to 30,000 m³/h
•                      HRW C, unit with all connections on top, air flow from 3,000 to 4,500 m³/h
•                      HRW IC standard, air flow from 3,000 to 30,000 m³/h including integrated cooling
•                      HRW HP standard outdoors setting with heat pump outside part (maximum 50 kW)

HRW standard
The HRW standard is the standard construction. All options are possible here. The standard units can be expanded with, among other things, integrated valves, heater, cooler, change-over, and silencers. Special modifications for, for example, connecting openings are possible as well.

HRW V
The HRW V has all duct connections on top of the unit. The V stands for vertical. This type has many advantages if technical rooms in which the unit will stand is reasonably full with for example distributors for floor heating.

HRW IC
HRW IC is a complete standard unit with a fully integrated coo­ling system. Can be applied both as indoor and outdoor setting. In the air charge towards the room a cooling battery is included. The heat of the cooling machine is placed via the condenser and discharged in the discharge air. The complete unit is filled and delivered ready for use – including a log file.

The application of this unit is very broad. In the basis, the ventilation air can be cooled. If cooling capacity in the room is desired, a higher ventilation capacity is required. We are glad to help you.

HRW HP
HRW HP is an addition to the complete standard unit in outdoor setting. The units are supplied with a heat pump outside part linked to it. The complete system is fully connected and filled. The OJ regulation itself directs the outside part and automatically switches over the system from cooling into heating capacity. The maximum heat pump capacity in cooling operation is max. 50 kW. This type can only be applied as outdoor setting. In the air charge towards the room a change-over battery is included. As a result of this, the cooling and heating is done with the same direct-expansion battery. The complete unit is filled and delivered ready for use – including a log file. The application is very broad though. In the basis, the ventilation air can be cooled. If cooling capacity in the room is desired, a higher ventilation capacity is required. We are glad to help you. These units can be operated with the standard OJ automatic as well.
