Reciprocating Compressors


High-pressure reciprocating compressor units

High-pressure hybrids of CMO and SMC reciprocating compressors, with swept volumes of 100–1100 m3/h

The blocks of the compressor units in the HPO/HPC/HPX range are cast in high-strength ductile iron, making them particularly strong and capable of operating under exceptionally high pressures.

This results in condensing temperatures of up to 90 °C, and makes HPX and HPO/HPC compressors ideal for use in conjunction with heat pumps and hot water applications, and as an extra “supercharge” stage in traditional ammonia plants. The renowned SABROE® high-pressure compressors are ideal for use with either ammonia or CO2 as refrigerant.

SABROE high-pressure compressors provide exceptional reliability and big savings on operating costs, because they are based on the high-volume CMO and SMC compressors, and they share the majority of castings and parts.


  • High coefficient of performance (COP), with excellent performance under partload conditions
  • Variable-speed drive (optional) provides stepless capacity control over the entire operating range
  • Provides exceptionally high condensing temperatures – up to 90 °C
  • Designed for easy service access, and repairs can be undertaken in situ, without removing the compressor
  • Special oil separator design based on coalescer technology
