GB/T 32710.10-2016 in English

1. Temperature control system

Standard requirementsElectric drying oven must be equipped with an over-temperature protection device independent of the main control system:

• The main heating element must be equipped with a double thermal circuit breaker, at least 1 of which is a non-automatic reset type
• The operating temperature of the protection device should be at least 50°C lower than the ignition point of the material
• Walk-in equipment must be equipped with an internal emergency unlocking device

2. Mechanical safety design

Special requirements for Electric blast drying oven:

• The door lock mechanism needs to prevent finger pinching (gap ≤4mm)
• The circulation fan is interlocked with the door, and the heating power is automatically cut off when the door is opened
• The glass observation window needs to be tempered and marked with an anti-scalding mark

Key points for equipment selection

1. Confirm that the protection level (IP code) marked on the equipment nameplate meets the use environment
2. Check whether the over-temperature protection device has an independent temperature sensor
3. IP21 and above protection models should be used in humid places

Maintenance and management specifications

1. Test the over-temperature protection device function every month (simulate over-temperature conditions)
2. Check the sealing of the door seal every quarter (heat leakage ≤5%)
3. Calibrate the temperature sensor annually (error within ±1℃)
