RC 6 SERIES

With the RC6, Grasso offers a new line of open reciprocating compressors with a number of specialized properties. In addition to innovative thinking in the field of compressor technology, these characteristics are also the result of the most advanced computer technology (CAE/CAM systems). In developing this new compressor, Grasso also utilized its extensive expertise in energy-saving techniques. Consequently, the new series of Grasso RC6 compressors represents the cutting edge of modern compressor technology. The RC6 compressors are significantly smaller than other comparable compressors, resulting in significant space savings.

Universal application

The Grasso RO6 compressor is ideally suited for use in refrigeration and freezing systems, in addition to heat pumps and air conditioning units.

Suitable for all halocarbon refrigerants

The Grasso RC6 compressor is compatible with all commonly used halocarbon refrigerants, such as R12, R22, R502, and R13B1.

Operating temperature range from -80°C to +-80°C

The Grasso RCE compressor has a maximum discharge pressure of 26 bar, allowing it to operate from evaporating temperatures as low as -80°C (R13B1) to condensing temperatures as high as +80°C (R12).

Extra high refrigerating capacity

Because the Grasso RC6 compressor is designed to operate on R13B1, it is possible to achieve extremely high refrigeration capacities at low evaporating temperatures.

Wider choice of drive units

The fastest speed that the Grasso RC6 compressor can go is 1800 rev/min. Because of this, there is a significantly greater selection of drive units available.

15% more energy saving

The RC6 is constructed so that its relative power consumption is extremely low. The result is a 15% reduction in energy consumption and ongoing cost savings.

Very high dependability

The Grasso RC6 compressor is exceedingly dependable, thanks to its high-quality construction. Two factors account for this:

• first its simple but ingenious design and

• Second, the high quality of the materials used, with particular attention paid to the wear-prone areas. The RC6 compressor’s maintenance schedule has been drastically reduced. special tools are not required
