We are retrofitting heating of Washing machines in machine shops and Surface preparation tanks by RADHEAT gas heating elements. In washing machines in machine shops we are retrofitting Electric Heaters by Gas Heating Elements as a result we are getting a more uniform temperature of the water and solution in the washing machine , which in turn is helping in reducing the process time for cleaning of the machined pats, and also we are able to save upto 40% in energy cost , the payback of these systems are less than 1 year.
