Using a variable frequency drive and make-up unit with a stainless steel heat exchanger, the Nova Verta system warms air and safely recirculates it through the Prep Station – without exposing operators or other shop employees to the dangers of carbon monoxide. No other prep station or paint booth provides a prep cycle that creates OSHA-mandated working conditions, heats the air, maintains air pressure, brings metal to the desired spray temperature, and generates monthly utility savings of 35% or more when compared to competitive systems in its class.
