KRONOS WDP chiller

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 KRONOS WDP chiller series from Secon is equipped with two semi-hermetic reciprocating compressors, which were specially developed for use with flammable refrigerants. The capacity control is either stepless via inverter or stepped.

So-called true-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 operation (partial load).

For applications with supply 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 stainless steel and components such as two flow monitors and temperature sensors are standard equipment.
