Fluorocarbon refrigeration unit

Features

• High efficiency

  (1) If one compressor fails, the remaining compressors can continue operating.
  (2) Fully automatic operation supports efficient performance and low running costs.
  (3) Systems can be configured for refrigerants including R22, R134a, R404A and R507A.

• Energy efficiency

  (1) Staged capacity control combines multiple compressors to match cooling output to actual demand.
  (2) Carefully designed piping minimizes pressure losses and improves unit efficiency.
  (3) An efficient main oil separator helps improve heat exchanger performance.
  (4) Multiple suction branches support energy-efficient operating conditions.

• Reliable operation

  (1) High-quality imported compressors and control valves support reliability and long service life.
  (2) Parallel operation balances compressor running hours automatically. The source states a service-life increase of over 30% compared with a single-compressor unit.
  (3) A condensing pressure stabilizer maintains a relatively steady pressure for stable system operation.
  (4) An efficient gas-liquid separator and dedicated piping design help reduce the risk of liquid slugging.
  (5) Protection covers phase loss, reverse phase, overvoltage, undervoltage, high and low oil pressure, high discharge pressure, low suction pressure, low liquid level and motor overload.
  (6) Fault isolation allows other compressors to continue operating when one compressor fails, helping maintain production.

• Staged capacity control reduces electrical startup impact

  Sequential, time-delayed compressor starting reduces the electrical impact on the customer’s power supply.
