cycle max time 999hrs.
3. Two chamber structures, high temperature chamber and low
temperature chamber, control automatically, stay and switch time
adjustable.
4. Perfect protection alarm functions: short-circuits, Leakage,
over temperature of work chamber; compressor over pressure, over
load, short water…
5. Control interface will display alarm reason and provide check
methods, machine has emergency stop button.
6. Cold and hot shock temperature recover within1 minute, which
complies with MTL, IEC, JIS, GJB and other international standards.
High temperature chamber:
1, Including three parts: heater, draught fan and air duct valve
2, Draught fan cyclically stirs hot air through heater
3, The basket with testing product drive to high temperature range
when doing high temperature impact test.
Low temperature chamber:
1, Including four parts: evaporator, energy storage piece, draught
fan and air duct valve
2, Draught fan cyclically stirs cold air through evaporator and
energy storage piece.
3, The basket with testing product drive to low temperature range
when doing low temperature impact test.
