Our history
Our history
Relocates some production from Italy to Slovakia and begins Shell & Tube Heat Exchanger production in Italy
Designing products for use with natural refrigerants and energy efficient systems is our key process.
Natural refrigerants
Roen Est designs its products for the potential use of CO₂, Propane and Ammonia natural refrigerants after the sale. To accomplish this, our products can be produced in different materials as needed, choosing between copper and stainless steel.
AMMONIA (R717)
Ammonia is the most widely used natural refrigerant for large industrial applications. With a GWP of 0, Ammonia is a cost-effective, efficient, and sustainable alternative refrigerant.
CO₂ (R744)
CO₂ is a naturally occurring, non-ozone-depleting refrigerant that addresses today’s concerns about the global warming potential (GWP) of common F-gases. With a GWP of 1, CO₂ is widely and effectively used in commercial and industrial refrigeration systems.
PROPANE (R290)
With its excellent thermodynamic properties and a GWP of 3, Propane is an energy efficient, reliable, versatile, and cost-effective natural refrigerant.
WATER (R718)
With a GWP of 0 and relative stability in cooling capacity compared with other refrigerants, Water is an ideal natural refrigerant for heat exchanger applications.
