As an industry leader in temperature-controlled storage solutions, Leer is committed to staying at the forefront of ever-changing technologies, market demand, and the world we live in. We strive to continuously adapt to these conditions so we can consistently offer our customers best-in-industry products.
Since Leer began manufacturing Ice Merchandisers in 1952, R290 will be the fourth primary refrigerant offered.
R12 was the go-to refrigerant from its introduction in the 1930’s until the 1990’s. Since then, technology improvements and environmental awareness have driven refrigerant transitions every 10-15 years. Our last transition was in 2007 when we began using R404a. Technology and global environmental awareness have enabled the introduction of a much-improved refrigerant, R290, in 2020.
Ozone Depletion Potential (ODP) = The measure of the effectiveness in removing ozone, relative to standard compound (CFC-11/R11).
Global Warming Potential (GWP) = The measure of the ability of a gas to trap heat in the atmosphere, relative to carbon dioxide (CO 2 ).
Thermal Conductivity = The ability of material to transfer heat, measured in Btu/hr-ft- o F. Values listed are via ASHRAE. A higher value is better.
