Introducing the high low lift Liquid Pressure Amplifier, LPA® for Compressor cooling, for lower (CR) Compression Ratios, for increased efficiency and piece of mind. In addition the newly invented  DX ThermOstore© below has some unique features.  Newly developed and in production, Model 809-DS (Dual Stage) is a pump/motor combination that is designed to dissipate the entire […]

All HYSAVE® LPA® liquid refrigerant pumps have been assigned a design working pressure  of 80 bars thanks to very important design constraints engineered by their technical team over the past year. The HYSAVE team welcome the news and enhance their pressure testing and helium leaks testing facilities to meet with these higher operating pressures according to […]

The model 809-SS-050-STD-B-NH3 is supplied with Stainless Steel connections making it suitable for Ammonia refrigerant applications. Flow rates range between 0.5 to 5 GPM with pumping heads up to 18′ make this the ideal LPA pump for purpose. Contact us for higher flow rates if necessary. We have two different front housing designs, one as […]

“Initial testing and performance of the 820-DSâ„¢ liquid refrigerant pump far surpassed all expectations  in dual stage technology low / high lift applications for both compressor de-superheating, superheat suppression or liquid injection  cooling technologies provided. The 820-DS (Dual Stage) is a high head low NPSH fractional horse-power (0.33hp) liquid refrigerant pump that is self-unloading and unique in […]

Liquid Pressure Amplification, (LPA®) invented by HY-SAVE in 1986 is still the most efficient energy saving technology available for commercial refrigeration or air conditioning today. The LPA works by boosting liquid refrigerant through the refrigeration system. By increasing the liquid’s pressure, the associated saturation temperature is raised, while the liquid temperature remains the same. The liquid becomes […]

HY-SAVE expands their production facilities to include manufacturing of LPA® pumps, DX Free Cooling, DX Re-Circulation and DX Plate Thermal Storage Technologies. Over the past 10 years, HY-SAVE has developed a cost effective range of LPA pumps developed for high pressure fluids such as Co2 for energy efficient refrigeration or air conditioning applications. Installation is […]

A NH3 cascade style first stage condenser and liquid receiver application provides efficient operation for medium and low temperature refrigeration circuits for HFC or Co2 blends. Refrigerant delivered to both medium and low temperature evaporators use a combination of DX Free Cooling and low stage vapor compression to maintain desired temperatures.  

The Co2 LPA® pump is a semi-hermetically sealed unit with important design features: The impeller floats in a revolving magnetic field and is the only moving part.The magnetic flux is supplied by an external motor with a magnetic coupling device. Because the motor is external to the system, a burnout cannot contaminate the system. The […]

DXFCâ„¢ – Split Air Conditioner 48,000 to 60,000 Btu’s. View data sheet. COP (Coefficient of Performance) Up to 50:1  0.35kW of electrical consumption removes 17.5kW of electrical heat, suitable for data centers, office server rooms and other areas of intense heat extraction requirements at a fraction of the cost.
