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.
