Product information

The liquid-cooled chillers of the KRONOS WDP series have a closed machine housing and are designed for indoor installation as standard. With the optionally available weatherproof housing, however, they can also be installed outdoors. The capacity control is either stepless via inverter or stepped.


So-called dual plates are used on the evaporator and condenser sides that means both refrigerant circuits are merged into one hydraulic circuit. Only with True-Dual is the respective refrigerant circuit 100% in contact with the heat transfer medium and therefore guarantees full efficiency, even when the other refrigerant circuit is out of service (partial load).


The Compact chillers of the FXP series are particularly space-saving liquid-cooled chillers. They are designed exclusively for indoor installation. The units can be operated as an individual unit or in a hydraulic network consisting of several compact chillers. The modules are ideal for retrofit applications in existing buildings with very limited installation areas. The capacity control is either stepless (obligatory for single units) via inverter or stepped (only for compound applications).


The series is characterised by extremely low refrigerant charge. Depending on the model, the refrigerant charge size per circuit is between 0,7 and 2,5 kg, which makes installation below ground level easier. Individual units have an integrated control system. In compound systems, the unit can be controlled either centrally or by a master system control (both optionally available).


Both model series are equipped with semi-hermetic reciprocating compressors, which were specially developed for use with flammable refrigerants.


For applications with outlet temperatures above -5°C, R290 (propane) is used. For lower outlet temperatures and especially for LT-applications, R1270 (propene) is preferred. The series can also be used as a hydraulically reversible heat pump. If this involves heat pump operation in the high temperature range (> 60°C), R600a (Isobutane) is used.


All components used comply with the highest quality standards and valid safety requirements. All units are subjected to a test run with functional checks before delivery.


The hydraulic piping is made of copper or stainless steel and components such as two flow monitors and temperature sensors are standard equipment.
