COMPRESSORS While working on lower frequency for
prolonged periods of time an oil return sequence brings the oil back to the compressor to protect it. With fl exibility in mind, Aersave also has multiple dip switch settings that can be switched dependent on the compressor type whether it is a reciprocating or scroll. It also controls the fan motor whether it is a condenser or evaporator fan motor.
As the technology can work with any type
of refrigerant, there is no need to cut into the refrigerant line.
Trial site The compressor technology was successfully
trialled by one of the largest fresh food manufacturers in Ireland. The unit was independently monitored and was shown to deliver a reduction in electrical consumption of 41%. Key features include:
■ Converts any 3-phase fi xed speed compressor to a variable speed

■ Controls and monitors the compressor with temperature sensors
■ Protects the compressor from working with abnormally high discharge temperatures
■ Voltage optimisation and eliminates inrush current.
According to UK government fi gures, 59% of energy consumed comes from the commercial
building sector with heating, air conditioning, ventilation, and refrigeration equipment amongst the highest electricity users. Aersave off ers a tangible solution for reducing the running of these systems. Customers across a wide range of industries can benefi t from system effi ciencies with minimal environmental impact.
