Groundbreaking compressor technology offers up to 50% savings

Aermec has launched Aersave, a groundbreaking technology for scroll compressors that can protect customers from rising energy costs by improving the energy efficiency of their chillers and deliver up to 50% energy savings.

Aermec's Aersave can help customers improve energy efficiency

Compressors on chillers are large energy users and replacing them with more energy efficient systems is primarily the only solution.

But now there’s an alternative – Aersave, the latest addition to Aermec’s portfolio of chiller technologies.

“Energy usage is one of our customers’ largest costs and concerns. Aersave can help businesses significantly improve the energy efficiency of their chillers by as much as 50% whilst increasing their lifespan and boosting their ROI.” Says Paul Lawrence

Aermec’s Aersave is a major leap forward in chiller technology. It is a proven innovation that can help mitigate against rising energy costs whilst increasing performance levels, longevity of existing chillers and help customers transition towards the government’s net zero target.

The Aersave smart compressor controller converts any 3-phase fixed speed compressor to a variable speed compressor. Aersave can be used on any manufacturers’ chillers, operates with any refrigerant and is compatible with all brands of BMS systems.

By enabling compressors to work smarter, Aersave eases reliance on the electrical grid, increases reliability, offers compressor protection, and can easily be retrofitted by any air conditioning or refrigerant engineer.

The benefits are decreased noise levels, precise room temperature and humidity control, protects compressor from short cycling and there is no interference with existing controls.

Operation

Aersave comprises two sensors instead of pressure transducers. One connects onto the suction line of the compressor, the other to the discharge line.

Its unique compressor control gathers the temperature from the two sensors’ points, together with gathering data via Modbus from the device via the compressor, which are then input to an algorithm, which calculates what speed and compressor capacity is required for the complete system to achieve its demand capacity.

While working on lower frequency for prolonged periods of time an oil return sequence brings the oil back to the compressor to protect it

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 where the chiller delivered a reduction in electrical consumption of 41%.

Key features:

- Converts any 3-phase fixed 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

Aermec has a long history of innovative manufacturing. Aersave is the latest product that will enable customers to benefit from the best energy efficient solutions across a wide range of industries with minimal environmental impact.
