Working with Mechanical Solutions Inc. (MSI), a small business in New Jersey, the U.S. Department of Energy’s (DOE’s) Building Technologies Office has found a potential solution to allow for cold climate heat pumps: a “supercharger” that enables heat pumps to efficiently operate in the coldest U.S. climates, with zero backup heat.

The Robur RTAR is a modular, reversible cycle gas absorption heat pump system capable of producing hot water up to 140°F and chilled water down to 41°F.
