Heating and cooling - ground/ground water as heat source
Passive cooling with brine-to-water or water-to-water heat pumps
Passive cooling station with cooling controller
PKS .. Econ
Module for passive cooling via borehole heat exchangers. Consists of heat exchanger, brine circulating pump, temperature sensor,
passive cooling controller, 3-way distribution valve with electrothermal actuator included. Cooling operating mode is added to the
existing heat pump manager by an electronic connection between the heating and cooling controller. The components are permanently
mounted in a white sheet metal casing, which can be mounted vertically or horizontally.

Passive cooling controller
WPM Econ PK
Wall-mounted cooling controller with temperature sensors to record the flow and return temperatures. The passive cooling controller
adds the cooling operating mode to the existing heat pump manager. Both controllers are operated within the network and control a
combined system for heating and passive cooling with brine-to-water or water-to-water heat pumps. The cooling capacity is transferred
via a heat exchanger not included in the scope of supply. This heat exchanger must be dimensioned according to the cooling capacity to
be transferred, the volume flow and the water quality.
