Description
Benefits:
R513A refrigerant has a low GWP and meets ErP Directive 2009/125/EC seasonal energy efficiency requirements.
High energy efficiency levels, especially for partial loads;
Smart, stepless cooling capacity regulation with self-adaptive control;
Cooling capacity regulation is highly accurate and adaptable.
Single compressors’ minimum capacity step is 25%.
Reduce pumping system management expenses by using heat exchangers with modest water side pressure decreases.
Integrated heat recovery systems (partial or complete heat recovery);
The water temperature at the condenser exit might reach 60 degrees Celsius.
Standard features:
High efficiency screw compressors with sophisticated stepless cooling capacity regulation optimized for the R513A refrigerant;
Check and shut off valves on the compressor’s discharge line;
Compressor crankcase heater and phase monitor.
Automatic circuit breakers for compressors.
Electronic expansion valves.
Single-pass shell and tube heat exchangers optimized for R513A refrigerant.
“Unloading” function that allows the start-up and operation of the units, even under conditions substantially different from the nominal ones;
Programmable microprocessor electronic control with high processing capacity and user-friendly interface, compatible with RS485 Modbus protocol supervisor systems;
Electrical cabinets have an IP54 protection grade.
Inspections and tests were conducted on all units;
Non-freezing oil and refrigerant are factory charged.
Options:
Features include soundproof compressor housing and a water-side heat pump with reversible arrangement.
MWT design, for low outlet water temperatures (down to -8°C);
Partial heat recovery: desuperheater (20% heat recovery);
