ZB19KQE-PFJ-558 COPELAND ZB SERIES SCROLL COMPRESSORS
Copeland refrigeration scroll compressors offer outstanding solutions for medium and high temperature applications. ZB Series of refrigeration scroll compressors are ideal for compact system designs that require a high degree of reliability and energy-efficiency. Applicable refrigerants include R22, R404A, R507 and R134a.
Dual Compliance:
This design ensures good sealing between the scroll spirals. It allows the scroll spirals to contact and separate along the radial and axial directions. Debris or liquid can go through the scroll disks without damaging the compressor. This results in: * longer lifetime and better reliability * better liquid handling capability * better handling of debris.
Designed for high energy-efficiency:
The scroll spirals in a scroll compressor wear in, rather than wear out. Over time, the wear-in improves performance. This ensures a very high volumetric efficiency.
Designed for lower noise and vibration:
The scroll design creates a smooth sound spectrum and better sound quality. The layout of the compression chambers is symmetric, making for very minimal imbalances. Manufacturing accuracy of scroll compressors is quite high. Scroll compressors do not normally require any vibration-absorbing device.
"Unloaded Start" technique:
After shut down, the two scroll forms are separated from each other. This enables full internal pressure equalization at shut down. For this reason, additional start capacitors are not normally necessary at start-up of single phase models.
