Compressors

Large single-stage compressors with swept volumes of 200–1350 m3 /h

SMC compressor units are ideal for use in medium-sized refrigeration installations where reliable service is a major priority. They are particularly effective under partload conditions. SABROE SMC compressors are world-renowned for their exceptional reliability, making them an economical, low-maintenance solution for heavy-duty refrigeration, using all common refrigerants. Range Fifteen different models are available to provide swept volumes of between 226 and 1357 m3 /h.

High-pressure hybrids of CMO and SMC reciprocating compressors, with swept volumes of 100–800 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.

Two-stage versions of CMO and SMC reciprocating compressors, with swept volumes of 150–1000 m3 /h

SABROE TCMO/TSMC two-stage reciprocating compressors are an economical operating alternative to single-stage compressors in smaller low-temperature refrigeration installations. TCMO/TSMC compressor units are also ideal for mediumsize industrial refrigeration installations that involve a big temperature range, such as freezer installations. Furthermore, these units are easy to customise with intermediate cooling systems. Using a two-stage set-up built together as a single unit helps avoid equipment duplication – and thus reduce costs and save space. Range Eight different models are available to provide swept volumes of between 146 and 1018 m3 /h.

Small screw compressor units with swept volumes of 160–950 m3 /h

SABROE SABflex screw compressors are specially designed for installations where the requirements for refrigeration capacity vary over time. These smaller-size units are optimised to ensure exceptional part-load performance as well as the best possible energy efficiency. Everything about these units is configured for use with variable-speed drive (VSD), doing away with the traditional capacity slide and ensuring skip-free performance across the entire 1,000–6,000 rpm capacity range. The VSD drive can be mounted on the unit, or separately in an appropriate switchboard room. Range SABflex units are available to provide swept volumes of 160–950 m3 /h at 6000 rpm using a high-speed motor, or 160–570 m3 /h at 3600 rpm using a standard motor.

Small single-stage compressors with swept volumes of 200–1000 m3 /h

SABROE SAB screw compressors are designed and configured to tackle smaller-scale industrial refrigeration requirements where a combination of exceptional reliability, high performance and low operating costs is essential. These small units can be used with all the most common refrigerants and process gases, and all the components are selected for good accessibility and ease of service, ensuring cost-effective maintenance. Range Eight different models are available to provide swept volumes of 204–1016 m3 /h.

Large single-stage compressors with swept volumes of 850–11000 m3 /h

The bigger models of SABROE SAB screw compressors are specifically engineered to deal with larger-scale industrial refrigeration installations in which requirements prioritise exceptional reliability, high performance and low operating costs. All the components are designed and configured to ensure low maintenance costs as a result of good accessibility and ease of service. Like their smaller counterparts, these large-capacity compressor units can be used with all common refrigerants and process gases. Range Thirteen different models are available to provide swept volumes of 848–11016 m3 /h.

Variable-speed high-pressure screw compressor units with swept volumes of 100–4200 m3 /hour, for use with ammonia or CO2 as refrigerant

These unique high-pressure compressor units are ideal for large site-built ammonia heat pump installations that condense at either 90°C or 72°C. They are also the ideal choice for larger CO2 systems or low-temperature two-stage freezer installations, such as carbon dioxide–ammonia (R744–R717) cascade refrigeration systems. Using CO2 as refrigerant makes it possible to make big savings on installation, piping and compressor costs because a single compressor unit can replace multiple compressors using traditional refrigerants. SABROE SAB high-pressure screw compressors are specially designed for variable-speed operation and maximum flexibility, doing away with the traditional capacity limitations of slidevalve technology. The capacity range of all SAB models extends from 1000rpm to maximum rpm. The SAB 193, 233, 283 and 355 high-pressure configurations, all ductile iron-cased versions of the large SABROE compressor units, provide substantial base load capacities along with providing exceptional flexibility in frequency converter operation. This ensures the robustness and reliability derived from the thousands of compressors in long-term service in refrigeration plants worldwide.
