The explosion-proof boxes of the MAXIMUS series have been certified and designed to meet the strictest standards relating to installations in potentially explosive environments, due to the presence of gas and dust flammable. The MAXIMUS series guarantees exceptional performance for surveillance critical processes in areas at risk of explosion, such as: refineries, gas pipelines, oil installations, off-shore platforms, processes industrial, chemical industries, etc. Equipped with heating, the box has assembly and service temperatures coincidental, from -40 deg C to +60 deg C. In the version with wiper, MHX is equipped with a telemetry receiver integrated which allows, via the RS-485 serial interface, to receive remote data for activating the wiper/washer and for the switching on of a possible external projector. Wiring is made easy thanks to the removable connectors on the connection circuit. The control card with extractable connectors is also equipped with a input for activating the wiper by dry contact. The box can, optionally, be controlled by a VMS using an encoder video equipped with RS485 serial port.
