Description
Tunnel type ovens are convection ovens that are used for curing of electrostatic powder coated workpieces usually at the temperature range between 180 and 200°C in 10 minutes. These ovens are used in the powder coating systems.
Our long experience in designing of powder coating systems defines how our new powder coating curing ovens are designed currently. When working on the design we always consider how these ovens should work and provide the highest efficiency as well as achieve desired set temperature while showing the lowest use of energy.
Our ovens can be produced in different size options in order to satisfy any customer’s requirements and desire. However, it is made for extra price but the given price does not include trolleys.
