“Don’t burn your profits,” was the message from presenter Brigitte Busch, who showed onlookers that she could change a valve without being injured from brazing heat. “OEMs do not have to face the expense of field replacements needed when valves fail due to unseen damage done by brazing heat.”
According to Danfoss, its bi-metal valve connections do not require an abundant amount of heat during brazing. They also retain brazing heat in the connection rather than conducting it to the valve body and power element, where it can cause hidden damage. First offered of its TU series of smaller stainless steel expansion valves, Danfoss said it now makes bi-metal connections available on larger brass-bodied valves for air-conditioning applications, and on a range of solenoid valves.

Lee also noted the broadening of its offering of type SC compressors for 115V and 230V at 60 Hz, adding 16 new models to its commercial line of fractional horsepower hermetic compressors. Approved for use with R-134a and R-404A/507, these compressors are suited to commercial applications such as vending machines, bottle coolers, ice machines, food and beverage merchandisers, and scientific equipment in all commercial refrigeration temperature ranges, said Lee.
