Emerson Copeland Liquid Injected Scroll Compressor ZF49KQE-TFD-564 Threaded Commercial Applications

ZF, ZFI series compressors for R22, R404A, R407A/C, R407F, R134a, R448A and R449A refrigerants.

(R134a is available in some models).

- Copeland's unique flexible scroll design, relying on centrifugal force to engage the scroll disks with each other, to ensure efficient operation while reducing gas leakage.

- ZF, ZFI series compressors can operate at condensing temperatures as low as 4.4°C, providing high seasonal energy efficiency.

- Dynamic exhaust valves on the compressors allow the compressor discharge pressure to be adjusted according to requirements, preventing recompression of the gas inside the compressor and providing a significant increase in energy efficiency at high pressure ratios.

- The Jet Enhancement technology allows the ZFI compressor to be more efficient than a single-stage compressor at low temperatures, resulting in superior performance.

- The ZF and ZFI compressors are equipped with built-in motor protection to prevent motor overheating due to phase failure or insufficient refrigerant charge.

- The ZF series is equipped with a DTC injection valve to control the compressor discharge temperature.

- The ZFI series can be equipped with Emerson's EVI injection kit to control the injection circuit and ensure that the compressor operates at a safe discharge temperature.
