Heater with explosion-proof fan it may be used in facilities with special security requirements such as woodworking shops, paint shops, welding shops, etc. |
|
Control system - controls are chosen individually according to the explosion risk level in a given facility. They should be manufactured in an explosion-proof version of at least the same level as the fan. |
|
Selection - in order to maintain the maximum-security level, the controlling automatics and electrical connections should be chosen individually according to the explosion risk level in a given object. |
