Task of the KTL curing oven is the curing of KTL paint on the part surface. The curing oven is built from sandwich panels, internal holding frame, air heater unit, internal and external air technology. Depending on design they have doors or air curtain. The inner air circulating of the KTL curing oven is more intensive, than the circulating of the powder curing oven. The oven has an airproof structure to have minimal heat loss during the operation. The KTL curing oven can have continuous or tact operation. A diagram can be made about every single curing. The controlling can happen with relays (at smaller, simpler oven) or with PLC. In case of PLC controlling we ensure remote supervision. The structure of the plant (panel elements) has at least 3 layers and mineral wool isolation with 120 kg/m3 consistence. The structure is made with panel connection protection, so we can minimise heat loss.
