Cabinet: Double-walled cabinet with outer made of mild steel, and inner chamber can be of mild steel or stainless steel as required.
Insulation: Glass wool filled between the walls to a minimum thickness of 2 inches.
Door: The door is fitted with heavy chrome plated brass hinges, and it contains a 'spring and roller' type latch.
Element Cover: The element cover is without perforations and it covers the heaters completely.
Finish: Outer side is painted with enamel paint. The inner side (in case of mild steel) is painted with heat-resistive aluminum paint.
Heating and Control
Heating: Heating is carried out by a specially designed low-rating electric heater.
Control: The temperature is controlled by a thermostat. For better accuracy and safety of the oven, Digital Temperature Controller (PEW-202) can be provided at an extra cost.
Temp. Range: For PEW-150ST: 5OC above the ambient temperature to 250OC maximum.
For PEW-150 FAC: 5OC above the ambient temperature to 150OC maximum.
For PEW-150 FAD: 5OC above the ambient temperature to 250OC maximum. (up to 300OC can be provided, at an extra cost)
Accuracy: Better than ± 5OC.
PEW-150 ST: The fresh air from the bottom inlet passes over a set of heaters and enters into the working chamber through the perforations of the false side partition wall. The hot air is exhausted through the chimney provided at the top. No separate blower is provided. The butterfly valve provided in the chimney can control air circulation.
PEW-150 FAC: The air passes over a set of heaters and enters into the working chamber through the perforation of the false side partition wall. The hot air draft from the top is again re-circulated by passing it to the inlet of the blower by means of the ducting. The butterfly valve provided in the ducting can control air circulation by feeding totally hot air or a mixture with the fresh air to the inlet of the blower.
PEW-150 FAD: The air is circulated by means of a motorized blower, that is, forced air draft is used instead of natural air. No re-circulation of air is possible
Note1: The inner chamber size can be modified according to the requirements.
Note2: PEW-150 FAD can be provided to work on 440V AC (3 phase).
