Ex d Explosion Proof Enclosure

Its function is to withhold an eventual explosion inside the enclosure without allowing it to escape to the surrounding atmosphere by means of flame paths.

This type of enclosure contains all the high power components (motors, transformers, lamps, electronic devices) that might cause arcs and sparks.

Ex i Intrinsic Safety

The protection is based on the principle of the energetic limitation, placing limits for applicable current and tension in dangerous zones also in the case of breakdowns by means of making suitable circuits.

The energy released from the circuit must be less than the minimum air-gas ignition energy present in the hazardous area.

Ex m Reasing Sealing

This is a type of protection based on a resin sealing of the electric parts that might ignite a dangerous mixture through sparking or overheating. It is generally used to protect solenoid valves and electronic circuits.

Ex q Powder Filling

This is a type of protection based on a powder filling of the electric parts that might ignite a dangerous mixture through sparking or overheating. It is generally used to protect control unit and electronic circuit.

Ex e Increased Safety

This is a type of protection based on the prevention and is suitable for: terminals, electric connections, non-sparking motors… It is generally used in our conversions for the protection of traction batteries and motors in alternative current.
