Product description
The hydraulic station is used for highly efficient heat and cold recovery in closed-cycle systems.
In winter, heat is extracted from the exhaust air flow from an exhaust air unit and transferred to a heat exchanger in the
central supply air unit.
The integrated controller monitors the operating conditions and regulates the optimum brine circulation amount. Frost
on the exhaust air heat exchanger and freezing of an optional heat feed are prevented by the control system.
Power control is achieved by a frequency-controlled pump and a power regulating valve.
The brine circulation amount is continuously recorded and can be used together with the temperature measurement for
heat quantity metering.
The decision whether heat recovery is possible and how much heat should be recovered must be made by a higher-level
building control technology.
Together with the building control technology, the station thus makes a significant contribution to saving energy and
reducing operating costs.
Optional components for extended use are:
Plate heat exchanger for heat feed
Plate heat exchanger for cold feed
Redundancy pump for increased operational safety
Warnings and faults are displayed and forwarded via potential-free contacts.
The control system can be easily integrated into higher-level systems via permanently configured bus systems: Modbus,
Bacnet/TCP-IP are available.
Our products are subject to continuous quality control, and comply with the applicable regulations.
