Premium-Grade Construction & Design

Robust Double-Wall Cabinet

The cabinet is designed in 6 / 12 / 24 / 48 / 196 tray configurations, featuring:

  • Heavy-duty MS & SS angle frame
  • Inner & outer walls with 18 SWG SS / 16 SWG MS sheet
  • 60 mm thick glass wool insulation to prevent heat loss
  • Industrial-grade fabrication to ensure long-term strength

This double-wall construction improves thermal efficiency and reduces energy consumption.

Heavy-Duty Airtight Doors

  • Each door is built with:
    • 16 SWG MS sheet construction
    • 50 mm glass wool insulation
    • Ball-catch locking system for secure closing
    • Asbestos gasket rope (40 mm) to maintain airtight sealing

    • Designed to withstand continuous high-temperature operations with zero heat leakage.

Efficient Air Circulation System

  • Uniform hot air circulation is ensured through:
    • Heavy-duty MS multi-blade fans
    • Ball-bearing pedestal mounting
    • Driven by 1 HP TEFC electric motor
    • Adjustable inlet & outlet dampers

    • This ensures consistent drying across all trays, improved heat transfer, and faster drying cycles.

High-Quality Heating System

  • Steam / Thermic Fluid Radiator
    • Finned Tube & Strip Tube radiator made from 14 SWG ERW tubes
    • 26 SWG CRCA MS fins (6 FPI) for superior heat exchange
    • Pressure-tested pneumatically at 7 kg/cm² (100 PSI)
  • Electrical Heating (Optional)
    • Strip-type heaters installed along sidewalls
    • Operates on 415V, 3-phase, 4-wire system

These heating options deliver stable temperature control and improved energy efficiency.

Industrial-Grade Trolleys

  • Each tray trolley is designed to withstand heavy loading and continuous operation
    • Frame built from 40 mm MS angle
    • Horizontal supports using 25 mm MS angle
    • Optimized design for smooth airflow
    • Fitted with 2 swivel castor wheels + 2 fixed wheels for easy mobility

Advanced Control Panel

  • A pre-wired control panel includes:
    • Digital temperature indicator & controller
    • Motor contactor & overcurrent relay
    • Fuses, pilot lamps, push buttons
    • Main isolator switch
    • Safety-protected electrical system
  • Premium Surface Finish
    • Inside & structure: Two coats of high-temperature aluminium paint
    • Outer cabinet: Red oxide primer + hammer tone finish This ensures long-term resistance to heat, corrosion, and industrial wear.
