Customers can be confident that ZB scroll compressors are coming from Emerson Climate Technologies experience of over 80 million 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. Available ZB Series is in the range of 2-15HP. Applicable refrigerants include R22, R404A, R507 and R134a.

* Complete range between 2-15 HP
* Proven reliability
* Superior efficiency
* Low sound levels
* Availability for HFC and HCFC refrigerants
* All voltage offering
* Oil sight glass & Rota lock features

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.

High-efficiency "Teflon" bearings:
High Efficiency "Teflon" is used for the upper main and drive bearing. "Space age" materials used in the compressor include:
(1) Porous bronze
(2) PTFE-lead overlay
There is exceptionally low friction. This also allows for extended operation without lubrication.

Refrigerating capacity data
Refrigerating capacity data listed in this manual are applicable for power frequencies of 50Hz (speed of motor equals 2900rpm) and 60Hz (speed of motor equals 3500rpm). The scope of compressor operation should not exceed listed conditions.
