Monorail Overhead Conveyor Oven

The jobs are hanged at a comfortable height through hangers on the conveyor to pass through tunnel type oven. The conveyor can be chosen from 3 wheel with T-track, 4 wheel conveyor or I beam conveyor. The jigs / fixture are designed for product to product and NSW reveal its expertise for the same. The oven is supplied with oil fired heat exchanger and high power blower. The system can also be provided with electrical heating elements and temperature variation from zone to zone.

• Construction: The oven is made out of Mild steel or stainless steel sheets from both inside and outside or mild steel from outside and stainless/ G.I sheets from inside. The oven is duly painted with Enamel Paint giving a rich look from outside. The body is fully insulated with mineral wool to minimize the heat losses and the thickness of the wall varies from 50mm to 150mm depends up on the maximum working temperature of the oven.
• Choice of Air circulation: Vertical, horizontal or combination
• Heating Media: Electrical / Diesel / Gas
• Temperature Range: Ambient to 300°C
• Control panel: with Standard Controls
• Voltage Stabilizer: in case of diesel/gas fired heating system

• Temperature controller: PID with or without temp. Profiling (ramp & soak) can be provided with SSR/ SCR for optimum accuracy. The programming of PID can vary from 4 programmes to 99 programmes.
• Safety/Blind Temperature Control: Digital /Analog temperature controller can be provided for safety. It acts as a backup & does not allow temperature to shoot up in case of main temperature controller fails to operate.
• Conveyor speed control: Variable frequency drive is to increase or decrease the speed of the conveyor.
• Temperature Recorder: To monitor the uniformity of temperature at different points at the same time, Microprocessor based multi point strip chart or paper less, Temp. Indicator cum Recorder can be incorporated with the system.
• Automatic Exhaust System: Automatic forced exhaust system with or with out timer is used for materials which produce vapors in high volume.
• Doors: Insulated door can be provided to minimize the heat losses at both entry and the exit side of the oven. These doors can be the screw type manual operated or can be fully automated adjustable doors. In case of automated system, the door closes as soon as product clears the door and re-opens when the product approaches the oven.
• Servicing windows: To ease in accessibility, for the servicing and maintenance, Windows can be provided on different areas of the machine.
• Door switch: Door interlocking system with the conveyor system can be provided in case of automated door and servicing windows.
• Automatic Loading & Unloading: NSW provide automatic loader & unloader of components on the conveyor system.
• Heater Failure Indicator: Particular heater can be easily identified whether it is in working condition or not. If damaged can be easily replaced in very short span.
• Product Sensing Device: A sensor with output alarm can be provided to sense the component at unloading area so that it do not fall down from the conveyor.
• PLC With HMI / MMI: PLC can be provided for automation and integration of whole system, data feeding, process display and fault indication can be seen in MMI.
