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
