A wide range of semi-hermetic reciprocating single- and two-stage compressors with displacement range from 4 to 240
m3/h at 50Hz and electrical ratings from 0.50 to 80 HP. Suitable for conventional HFC-based , new low-GWP, HFO and natural refrigerants.
The compressors are suitable for use in a wide range of retail and industrial cooling applications, process chillers, air conditioning and
heat pumps; in single, multi-compressor systems and cascade systems. A wide range of accessories broadens their application versatility.
All models can work with inverter
Injection for motor cooling:
• Managed from the Motor Cooling
System module
• Very short duration
• Only the quantity necessary for motor
cooling is injected
• High efficiency
Motor Cooling System fully cabled in
the compressor electrical board
• TA module fully cabled in the
compressor electrical board
• Kriwan Diagnose available for the
compressor diagnostics
• It controls the motor temperature through AMS sensors during the critical starting phase!
• Detection threshold PRE-ALARM temperature: the module activates the liquid injection in the motor with correct quantity and duration
optimising the maximum COP
• Detection threshold CRITICAL TEMPERATURE: the module stops the compressor preventing the burn
• Stopping of injection in case of liquid absence in the system
• TA module included to stop the injection when the compressor is switched off
Possibility to manage the function directly from the control panel
