Solar Paint Shop Dryer

Solar Paint Shop Dryer

Automobile components, machine components and other almost all factory made gadgets use paint shop for creating good appearance as well as for resistance against exposure to rain, dust, chemicals, radiation and high and low temperatures. Paint coating of components is a complicated and step by step process, resulting in a 5-layer surface. Fossil fuels are used in paint shops, mainly air heating for paint curing. Curing air temperature ranges from 80° C to 150° C.

Why Solar

The purpose of solar air heater is to convert atmospheric air into hot air using sun radiation. The paint shop dryer/oven draws cold air and heating the air into 150°C by burning petroleum products. If pre heated air at 60°C to 95° C (depending upon the solar radiation) is provided to the dryer instead of cold air the fuel consumption could be reduced. Apart from creating profit to the paint shop using industries, environmental degradation including global warming is reduced by solar path.

What is the PEN solution

A 297 m2 area solar air heating system was installed, integrating on the south facing roof of the factory. The hot air obtained is drawn by a low electric power (1.5 kW) blower. The hot air is transmitted by insulated metal pipes to the fresh air inlet point of the paint shop dryer to preheat the air required for oven.
