Temperature Shock Chamber Fitoterm 150 CTE

The temperature shock test chamber FitoTerm 150CTE2, features two independent chambers on the same chassis, with the upper (Hot) chamber – heated by electric heaters and air circulation – reaching uniform temperatures of 200ºC; and the lower (Cold) chamber – with dynamic ventilation +/- 2m/s for homogenization and temperature uniformity – reaching cold temperatures down to -75°C.

Description

TEMPERATURE SHOCK CHAMBER
FITOTERM 150 CTE

The temperature shock test is carried out by transferring the test specimens between the two chambers through an electro-mechanical lift, with +/- 5
seconds of transfer time. Aralab’s evolution of the mechanical lifting system made possible to eliminate all vibrations on the lifting cradle, making a
smooth up and down movement while performing the tests.

  • Temperature changes: from -75° C to 200°C in 5 seconds.
  • Two independent (Hot/Cold) test spaces in the same chassis
  • Upper space has electrical heater and air circulation for optimal uniformity
  • Lower space has dynamic ventilation at +/- 2m/s for homogenization and uniformity of the temperature

Key Features

  • Simple and reliable functioning
  • Two independent (Hot / Cold) testing areas connected by electromechanical lift
  • Multifunctioning Hot and Cold testing zones can be used independently
  • Energy saving technology, temporarily cutting of the Hot or Cold zones when not in use during cycles
  • Nonpolluting construction and cooling system
  • Equipped with digital touch-screen CLIMAPLUS V controller
  • Reduced investment, low maintenance, reliable and accurate performance
  • Compliant with international standards and requirements EN, IEC, DIN, ISO, NP and UNE

 

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
