Six Cylinders 2 Stage Cooler Condensing Unit Reciprocating With Mechanical Expansion Tube

Bitzer Six Cylinders 30HP 2-stage Semi-hermetic Reciprocating refrigeration unit S6f-30.2Y for cold storage and chiller
Features:

KUB condensing units

Shell with high-quality steel, surface spray, corrosion-resistant, beautiful appearance.The use of copper tube misplaced way, the use of mechanical expansion tube, so that the brass and fins in close connection, good heat transfer effect.Products after 2.5PMa air tightness experiments and system sewage treatment.Applicable to R22, R134a, R404a, R407c and other refrigerants.

BITZER sets standards in technology and performance with the 2-stage compressors of the .2-Generation for extended low temperature applications. This series is the result of extensive research based on many years experi-ence in the construction of especially efficient and robust reciprocating compressorsm

These compressors were further developed in important details and optimized with regard to the changed demands with the application of alternative refrigerants especially for operation with HCFC R22 as well as HFC R404A and R507C

The experience with components proven over many years could thereby be employed, to provide an especially robust construction for a comprehensive application range. Gas ports and working valves are especially matched to low temperature operation. Together with the motor and drive parts of the .2-Generation which are designed for the highest efficiency an even higher performance is thereby achieved as with previous low temperature systems

One common compressors series for chlorine free HFC refrigerants and the HCFC's.

1, Retrofitting for HFC refrigerants:Use a polyol-ester oil which is approved by BITZER (suffix "Y"in type designation)

2, Match the expansion valve of the interstage cooling to the HFC refrigerant.

The most important design features:
Short gas canals Generously sized suction connection
Minimum heat exchange
Solid valve plate design
Valve reeds of impact resistant spring steel

Minimal space requirements
Very compact dimensions
Quiet and low vibration
4 and 6-cylinder design with optimised mass balance giving especially quiet running
