Rick RolandRick Rolandis the owner and engineer of Certified Refrigerant Services, Inc. which is located in Punta Gorda, Florida. Rick has been in the refrigerant reclamation industry since its inception in 1995; one of the first reclaimers in the country. From the age of ten, he grew up in his father’s HVAC company and eventually became the owner of a Carrier Leadership dealer culminating over 40 years of hands-on experience. Rick has designed and built all the refrigerant reclaim and separation equipment used at CRS including a patent pending Modular Separation Machine™ (MSM). This advance technology is only possible by possessing an acute understanding of refrigerants and their technical characteristics. Rick is a well known qualified leader and authority in the refrigerant management industry.

R-22 AlternativesUnlike R-22 the R-4XX

alternative refrigerants are BLENDS, or “zeotropic.”

ZEO Who?

Zeotrope: A mixture made up of two or more refrigerants with different boiling points. Zeotropic mixtures are similar to near-azeotropic mixtures with the exception of having a temperature glide greater than 10° F. Zeotropic mixtures should be charged in the liquid state.

Azeotrope A mixture made up of two or more refrigerants with similar boiling points that act as a single fluid. The components of azeotropic mixtures will not separate under normal operating conditions and can be charged as a vapor or liquid.
