Drying - Baking - Preheating

« back to production program

Application:
Gas fired continuous drying kilns are designed for drying, curing, baking and preheating up to 200°C.

Equipment Description:
Kilns are divided into heated sections with burners, cooling sections with ventilating flaps, final cooling usually by a battery of fans. Input and output table according to the technology.

Light steel construction is made of sectional steel and covered with a metal sheet covering. The kiln is lined with fibre felts which provides excellent economy, low thermal lost, fast heating and cooling, low weight and power input. The charge is transported on the wire belt. The belt velocity is adjustable, controlled by the convertor. The belt moves on the steel supports. Return part of the belt is supported by the rollers.

Radial recirculation fans situated on the kiln ceiling forces the air through the channel between outer and inner casing to the working room. The temperature is accurately controlled by means of process controllers and burner control units. Temperature is usually measured by thermistors and recorded by means of point - recorder.

Instruments are selected to provide a full range of features at an economical price. Consideration has also been given to selecting instruments that are easy to understand and use. Electric equipment and control devices are placed separately in the switchboard.

Electric heating

High quality heating elements – heating wire on ceramic tubes or closed into steel tubes. Power control by contactors, continuous or contact-less by thyristor units or solid state relays.

Gas heating

Gas burners are designed for different kinds of application and assembly alternatives. Complete sets of easily installed equipment and control units for safety operation.

Ovens and furnaces for heat treatment up to 450°C

Electric resistance box furnaces, car hearth furnaces or continuous furnaces are designed for baking, drying, preheating or any other heat application at temperature to 450°C.

Technical features:
Light steel construction is made of sectional steel and covered with a metal sheet covering. Light weight and fibre insulation provide excellent economy and minimum thermal loss, fast heating and cooling and low power input. Choice of horizontal or vertical air flow, rear, side, or top mounted heat chamber, electric or gas heating units. Electrical furnaces are heated by high quality heating elements.

Manual door opening or powered vertical lift doors. Automatic door switch turns off blower and heat when door is opened. Nominal voltage: 3 PEN, 400V, 50 Hz. Accurate temperature control (standard controller or programmable controller). Power control by solid state relay, thyristor units or contactors. Instruments have been selected to provide a full range of features at an economical price. Consideration has also been given to selecting instruments that are easy to understand and use.

Electric equipment and control devices are placed separately in the switchboard. Anti-explosive design available. „REALISTIC“ furnaces are designed according to your requirement.
