About HY‑SAVE®
Engineering Liquid Refrigerant Innovation Since 1984
Founded in Portland, Oregon in 1984, HY‑SAVE® has spent more than four decades advancing the science of liquid refrigerant pumping and liquid stability technologies. Our mission is simple and consistent: to enable cleaner, more efficient, and more reliable refrigeration and heat‑pump systems worldwide.
From the earliest LPA® prototypes to today’s advanced liquid‑stability solutions, HY‑SAVE® has remained focused on engineering innovation that delivers measurable improvements in system performance, energy consumption, and long‑term reliability.
A Legacy of Technical Innovation
For over 40 years, HY‑SAVE® has supported the development of:
- New liquid‑refrigerant pumping technologies
- Improved methods for stabilising refrigerant under low‑pressure conditions
- System designs that reduce compressor workload and energy consumption
- Solutions that support modern low‑GWP refrigerants and evolving global standards
Our technologies are used across commercial, industrial, and residential applications, helping engineers design systems that perform reliably in all climates and operating conditions.
LPA® — The Core of Our Product Range
At the centre of our product line is the LPA® (Liquid Pressure Amplification) pump — a fractional‑horsepower liquid refrigerant pump engineered to maintain a stable liquid supply to the expansion device.
For more than four decades, LPA® pumps have been trusted by OEMs, system designers, and engineering firms worldwide to:
- Improve liquid stability
- Prevent flashing in the liquid line
- Enhance TEV/EEV performance
- Enable floating‑head and low‑ambient operation
- Reduce compressor energy consumption
LPA® remains the industry’s benchmark for reliable, efficient liquid‑refrigerant pumping.
Our Commitment
HY‑SAVE® continues to invest in research, development, and engineering support to help the industry transition toward:
- Higher efficiency
- Lower environmental impact
- Greater system reliability
- Compatibility with next‑generation refrigerants
We remain dedicated to providing technologies that support global sustainability goals while delivering long‑term value to our customers.
