strengthen enclosure the strength, adjust the length and gap of the joint of
associate components and limit the maximum surface temperature.
The enclosure is able to subject to static pressure test (1.5 times for at least
10s) specified in EN60079-01:2014/IEC60079-1: 2014, no leakage or
deformation allowed after test.
The maximum surface temperature will no more than 80ºC in normal operation.
Tempering glass is adopted in observation port, the tempering glass shall pass
the impact and thermal shock test.
Ingress protection level: IP66,IP68(2m/2h).
Protection the flameproof surface in maintaining of this product, otherwise the
damaged flameproof surface will affect the Explosion-proof performance.
When the product needs anti-corrosion treatment (especially carbon steel), the
