The drying and curing ovens we produce at LEM Impianti in Carate Brianza are used for monoblock or panel-type painting, in line or with a bell applicator.
Our ovens consist of a sturdy internal steel structure with walls made of folded galvanized sheet metal, which is designed to ensure uniformly distributed ventilation throughout the interior of the oven.
The rock-wool insulation panels have an overall thickness of up to 200 mm depending on the operating temperatures.
The external walls are made of galvanized sheet-metal panels or insulated panels.
The maximum operating temperature is 300°C and methane gas or diesel may be used as fuel.
The rock-wool insulation panels have an overall thickness of up to 200 mm. The hot-air distribution assembly, which consists of a series of deflectors located near the bottom and resting on end, is useful for uniform heat distribution.
The combustion chamber is composed of:
- an opening in the upper part of the generator for air intake from the oven
- an opening in the lower part of the generator to expel air into the oven
- recirculated air renewal unit complete with regulation damper and chimney connection flange
- centrifugal fans to circulate air inside the oven, specially made for high temperatures with a cooling fan, connected to a 3-phase 4-pole asynchronous motor
- support structure made to allow the fan to be extracted
- suitably sized heat exchanger consisting of a combustion chamber in AISI 430 30/10 stainless steel, closed on one side with a removable plate containing holes for the burner and spy-hole, as well as a tube bundle
- electronic temperature control with 0–250°C digital indicator;
- probe for detecting the interior oven temperature
The entire system is designed for easy maintenance and internal cleaning and may also be extracted. The equipment is contained in a special case to be mounted on the electrical control panel.
