For facilities with extensive refrigeration requirements, refrigeration costs can easily account for up to 50% of the total energy bill.

As operations such as food stores, supermarkets and warehouses are discovering, the installation of hy|save refrigeration systems can significantly increase the energy efficiency and capacity of conventional direct-expansion refrigeration systems- well above that of standard, industry accepted systems.

As electric utility deregulation looms, there is no better time to fine-tune your existing commercial refrigeration for peak operating efficiency.

Non-OEM- specific hy|save refrigeration units can be retrofitted easily on your existing compressors.

hy|save Liquid delivery System (LDS).

Improving Refrigeration Dynamics For Peak Efficiency.

Patented hy|save refrigeration technology provides the most diverse means currently available for increased system efficiency. The formation of vapour or "flash gas" in the liquid refrigerant line is a major cause of inefficiency in the vapour compression type refrigeration cycle. Traditional cooling systems counteract flash gas formation by using elevated head pressures, which can prove costly in terms of energy use, operating efficiencies and maintenance/repair downtime.

The hy|save Liquid Delivery System (LDS) employs a specially designed liquid refrigerant pump to provide solid delivery of liquid refrigerant to the expansion valves.

Pumping liquid refrigerant is significantly more efficient than using elevated compressor head pressures. Pump pressure subcools the refrigerant by increasing the pressure in the liquid line which helps to ensure quality liquid refrigerant will reach the expansion valves.

The compressor no longer needs to work hard to maintain design head pressures which can now be "floated" with the ambient temperature.

Some Benefits:

• Internet monitoring and analysis.
• Stable refrigeration plant performance.
• Simple installation and commissioning.
• Pre-condensor discharge vapour de-superheating.
• Eliminates liquid line "flash gas".
• 100% liquid delivery to the expansions valves.
• Optimising and extending floating head pressures.
• Typically reduces energy consumption by 45%.
• System low refrigerant warning/alarm.
