NAVAC Inc. won Gold in the Electronic Tools category for its NRDC4M refrigerant recovery machine, which was created as an alternative to the conventional single- or dual-cylinder design.
“For most residential applications, those designs are adequate in terms of recovery speed,” said Stephen Rutherford, vice president of HVAC business at NAVAC Inc. “However, large HVAC systems used in commercial applications contain a significant amount of refrigerant, and conventional recovery units are too slow to do the job, or they require the use of cumbersome cart-mounted machines.”
