TVK-07-S Explosion-proof thermohousing in a galvanized low carbon steel body
Distinctive features and characteristics
- It is made of galvanized low carbon steel.
- The main purpose of the explosion-proof housing: video surveillance for maintaining security, safety and technological process control with simultaneous prevention of ignition or detonation of the media surrounding the camera due to faults in the camera’s electric circuits.
- It allows avoiding use of special explosion-proof cameras, which, combined with the large effective volume of the thermohousing, extends the range of cameras that can be installed in it.
- It can be used in underground (mining) development and extraction of coal, mineral salts and other mineral deposits.
- Availability of the hounsing’s internal volume heating system allows applying this device at an ambient temperature of up to -60 °С.
- Explosion proofness marking: РВ Ex d e I Mb X / 1Еx d e IIC T6 Gb X.
- Ingress protection rating of thermohousing enclosure is IP66/IР67 as per GOST 14254.
- Video equipment can be installed by the customer.
- New option! If necessary, it can be equipped with mounting adapter AK-S (pole mount) and AK-U (angle mount).
TVK-07-S is entered into Stock item identification guide MTR “Gazprom” OJSC.

The maximum current consumption of 3.3A is indicated for extreme opering conditions at ambient temperatures below -20°С (up to -60°С); it is necessary for heating of the interior space of TVK-07 and the sight glass. At an ambient temperature equal to -20°С or higher current consumption of TVK-07 does not exceed 0.8A, including the surveillance video camera’s current consumption.
