Construction

• Interior: AISI 304 hermetical welded, vapor tight, stainless steel
• Exterior: Zinc mild steel with epoxy coating finish (color RAL 7035)
• Window: Observation window in multiple layer glass (only in heating chamber)
• Thermal isolation: Rock wool
• Interior illumination: 12V halogen (only in the heat cabinet)
• Doors: Total opening with lock, double silicone joints and heating to prevent condensation

Climate and Temperature

• TEMPERATURE CONTROL
  Temperature control is made by the PLC Touch Screen ClimaPlus V controller,
  developed by Aralab and exclusively for its environmental test chambers.
• TEMPERATURE SENSORS
  • PT 100 DIN Class A, located in the air treatment tunnels. One in each chamber
  • PT 100 DIN Class A, mobile sensor
• HEATING
  Heating is achieved by tubular stainless steel electric heaters located in the
  air treatment tunnel. Temperature is attained by a dynamic ventilator at ±2 m/s
  with programmed interruptions during the upwards and downward movements
  of the lift.
• COOLING
  Cooling is achieved without use of CFC’s, by a hermetically sealed Scroll
  compressor (with low noise levels with great cooling efficiency) and also
  by water cooled refrigeration system. Temperature uniformity is attained by
  a dynamic ventilator at ±2 m/s with programmed interruptions during the
  upwards and downward movements of the lift.
• THERMAL SECURITY
  Safety thermostat with High / Low temperature configuration controlled by
  independent thermostats with integrated alarms.
• TRANSFER BETWEEN HOT AND COLD CHAMBERS
  • Transmission through ball spindle drive to eliminate vibrations and system
  deceleration when reaching up / down positions
  • The commutation between cabinets is done through an electromechanical
  elevator, with a transference time of +/- 5 seconds
  • Security stopping and blockage of the elevator when opening the doors
  • Bright indicator of elevator position and cycle:
  –Green – heat cabinet
  –White – cool cabinet
  — Intermittent – to stabilize the
