Refrigeration Compressors.

Most industrial refrigeration compressors are large, mechanical units that form the heart of industrial cooling and heating. They draw refrigerant from the evaporator at a relatively low pressure, compress it and then discharge it to a condenser where it is cooled.

The refrigerant then moves to the expansion valve and the evaporator – where it absorbs heat as it changes physical state - before being compressed again.

There are different types of compression mechanisms that are typically used in factory environments: reciprocating (piston), rotary (vane) and screw compressors (three different types).

The refrigeration compressors typically cool a glycol-water mixture or brine contained within a closed thermal exchange system, which is then used as a secondary coolant and pumped as required to chill or freeze environments or equipment, enabling producers to
lower the temperature of a product dramatically over a
short period of time.

Energy

A 45kw Screw Air Compressor running for 12hrs per day @ 50p/kWh, will cost £98,550 per annum to run (@ June 2022 prices). A 10% reduction in consumption due to optimisation will save nearly £10,000 every year.

Maintenance

  • Reduce the risk of unplanned failure, avoiding secondary damage and reducing MRO spend
  • Vibration data can highlight over or under lubrication of key components
  • Protect mechanical assets such as compressors using multiple vibration bands, combined with ‘smart’ early-warning alerts.
