Floor-mounted, wall-mounted or side-mounted, depending on final layout
Heating System
The oven is electrically heated using low-watt-density, sheathed tubular Incoloy/Inconel air heaters. The heaters are installed inside an isolated recirculating-air duct or plenum, preventing direct radiant heating of the product.
Parameter
Offered/Proposed Specification
Heating-element type
Sheathed tubular Incoloy/Inconel air heaters
Proposed heater capacity
Approximately 45 kW
Heater arrangement
Distributed inside an isolated recirculation duct/plenum
Heater control
Thyristor-based three-phase proportional power controller
Power-controller type
Slim three-phase electronic power controller
Component brands
Autonics, Schneider Electric, L&T or equivalent reputed brands
Heat distribution
Indirect forced-convection heating
Heater safety interlock
Heater operation interlocked with the air-circulation blower
Air-Circulation and Exhaust System
A heavy-duty centrifugal blower continuously recirculates heated air through engineered ducts, plenums and adjustable baffles. This arrangement minimizes temperature variation throughout the usable chamber.
Parameter
Offered/Proposed Specification
Air circulation
High-volume forced-air recirculation
Blower assembly
Heavy-duty motor-driven blower – 1 No.
Proposed blower motor
3 HP / approximately 2.2 kW, continuous-duty
Proposed airflow capacity
Approximately 4,500–6,000 m³/hour, subject to final duct-pressure calculation
Air distribution
Engineered rear and side plenums with suitable internal baffles
Fresh-air inlet
Adjustable fresh-air provision
Exhaust system
Adjustable vapour-exhaust outlets with damper arrangement
Exhaust points
Up to five vapour-exhaust points, as per final process design
Cooling performance
Designed to cool to approximately 70°C within 30 minutes after heater shutdown, subject to load, ambient conditions and airflow settings
