Welcome to our comprehensive guide on refrigerants' chemical makeup and properties. As a leading pump manufacturer for regenerative turbine pumps, we understand the critical importance of selecting the right refrigerant for your specific applications. Refrigerants play a pivotal role in various industries, from HVAC systems to industrial refrigeration units, and their chemical compositions significantly impact performance and environmental considerations. On this page, we look at a list of refrigerants, detailing their molecular structures, thermodynamic properties, and environmental impacts. Whether you're seeking information on traditional refrigerants like R-22 or exploring the latest environmentally-friendly alternatives such as HFOs, our detailed analysis will equip you with the knowledge needed to make informed decisions for your pumping systems. Explore our in-depth resources to discover the ideal refrigerant solutions tailored to your requirements.

We have broken down the list of refrigerants by compatibility to our HP Series refrigeration pumps.
