Features and benefits
1.Robust and reliable
Copeland Scroll compressors have 70% fewer moving parts than reciprocating compressors and feature a scroll Compliance mechanism which makes them particularly robust and reliable under severe conditions including liquid slugging.
2.Dual compliance
Compliance means sealing between the orbiting and fixed scroll involutes. Dual compliance means the sealing is on both the axial and radial directions. This prevents refrigerant leak back across successive scroll pressure pockets. Compliance design also allows the scroll involutes to separate in both the radial and axial directions. This allows debris or liquid refrigerant to pass through the scroll involutes without damaging the compresso r. Benefits of Dual Compliance are:
• Increased efficiency
• Better liquid handling capability
• Better handling of debris
3.Scroll wear in
The scroll involutes of Copeland scroll compressor wear in, rather than wear out. So unlike in other compressor technologies among similar categories, there is no constant degradation of performance with time due to wear out.
4.Lower sound, vibration and pulsation
The compression process in a scroll set is symmetrical and continuous. This inherently reduces the sound, vibration and pulsation.This eliminates the need for use of vibration absorbers and suction or discharge mufflers in most of the applications. In further,ZB scroll compressors are engineered to produce smooth sound spectrum which improves the quality of sound.
5.Compactness
Copeland Scroll have the advantage of light weight and compactness with small footprint, making them ideal for the usage in condensing units, compact refrigeration systems or special process units. Weight and dimensions for refrigeration equipment is reduced accordingly
6.High efficiency all year round
Copeland ZB Scroll is designed for medium-high temperature refrigeration and process cooling applications. Motor, scroll and bearing are optimized for high seasonal efficiency, which helps end user reduce life cycle cost all year round.
7.Multiple refrigerants
ZB compressors are approved for R404A, R507, R22, R134a, R407F, R448A and R449A refrigerants.
8.Unloaded start
The scroll sets separate at the instant of compressor shutdown. This allows the scroll set internal pressures to equalize on compressor stops. In addition to this, the scroll sets are not engaged at the instant of starting. Scroll sets engage only after few milliseconds of startup. This allows easier startup of ZB scroll compressors. Due to this design feature, typically a start assist kit is not required even on single phase compressors.
