DC Compressors

DC Compressor with inverter regulation

Innovative

Thanks to the brushless DC synchronous motor, a wide

modulation between 20% and 100% of the delivered

cooling capacity is possible.

The "High Pressure Shell" (HPS) system allows optimum

lubrication of the compressor even at the lowest speed,

separating the oil from the refrigerant directly inside the

compressor.

Simple

Thanks to the direct control via the Modbus® Master pro-

tocol a continuous monitoring of the compressor oper-

ating conditions is possible with direct access from the

terminal unit, or remotely via connection to supervision

systems and building management systems (BMS).

Flexible

Thanks to the wide adjustment range, the compressors

will automatically adapt to the actual cooling demand,

guaranteeing the optimal supply of cooling capacity even

in the presence of varying thermal loads.

Efcient

By optimizing the working conditions and efciency of the

brushless DC motor, it is possible to reduce the annual en-

ergy consumption by 35% in partial load.

It is moreover possible to increase the energy efciency

ratio (EER) by over 25% compared to a system with a

xed speed compressor.

Reliable

Thanks to the inverter control system, the brushless DC

motor and the "High Pressure Shell" system, it is possible

to ensure the system high functional efciency, minimiz-

ing the need to service the cooling circuit.

The direct expansion units of the SysTemp close control air

conditioning range can be equipped with DC compressors

with inverter regulation, which allow the delivered cooling

capacity to be varied, maximizing the motor performance

and reducing energy consumption.
