Chillers for outdoor installation (with "winter relief")

WRK-FK chillers are L&R chillers with integrated "winter relief" for outdoor installation. Winter relief (free cooling) means that a supplementary heat exchanger register is incorporated in the machine, via which cooling is effected when outside temperatures are low. During this time, the cold compressor does not need to operate, which creates significant energy savings. This additional cooling option also means double operational reliability in the transitional and cold weather seasons.

Complete control of the system is carried out via the L&R "Frigocontrol I" controller. This controller is a PLC with a Siemens control device. It controls the system and displays operating and fault reports in clear text. The controller automatically selects the most economical running mode and switches to "winter relief" mode automatically. The fans are speed-controlled.

Optionally, a router can be integrated into the control system in order to monitor the system from our service centre and to provide rapid assistance in the event of faults. We produce these systems with a cooling capacity ranging from 50 to 1,400 kW, expandable by modules.

Chillers are fitted with piston or screw compressors, depending on the cooling capacity. Depending on the customer's wishes, chillers are built with one refrigerating circuit or with a number of separate refrigerating circuits for greater operating security. The system is constructed according to the customer's requirements.
