TUNNEL TYPE POWDER COATING CURING OVENS

TUNNEL TYPE POWDER COATING OVENS
Tunnel type ovens are convection ovens which allows to electrostatic powder coated work pieces to be cured usually around at 180-200°C in 10 minutes. Oven length is calculated properly according to the conveyor speed in order to achieve curing of work pieces quantities per shift. The powder coating ovens are designed by us according to the shape, quantity and weight of the product to be cured.

The ovens are conveyorised, product inlet and outlets are opened according to the biggest work piece sizes. Oven shape can be designed as a tunnel, U-shape or W-shape according to the project and the work shop sizes.

Electricity, liquid or gas fuel is used for heating the ovens.

OVEN BODY
Tunnel type powder coating ovens consists of an oven body made of sandwich panels with thickness of 150mm filled with rock wool, oven heating unit, circulation fan and a heat-exchanger unit with burner for gas/diesel fired ovens or electrical resistances for electrical source ovens. Air curtains placed at the inlet and outlet of the oven prevents from hot air loss from oven to the environment. Temperature controller is digital type and easy adjustable, an emergency thermostat is used for safety.

WORKING PRINCIPLE
Ventilation air created by the circulation fans passes through the heating chamber, getting the heating energy with the highest efficiency and is transferred into the oven. Adjustable air blowing openings on the air-duct located at the base of the oven maintains homogenous air distribution at the set temperature. The heating chamber is manufactured from high temperatıre resistant stainless steel.

Powder coating ovens are designed according to our long experience in order to work with the highest efficiency to achieve needed temperature with the lowest energy use.

The ovens are CE certificated and conforms to the European Norms.
