MAXIMUS MHXTEx-proof housing for thermal cameras

MAXIMUS RANGE ... Drillereye




These explosion-proof housings for the MAXIMUS range have been certified and designed to meet the strictest standards regarding installation in potentially explosive environments, i.e. where there is the presence of gas and flammable dusts.

The MAXIMUS range ensures excellent performance for monitoring critical processes in areas that carry a risk of explosion, such as refineries, gas pipelines, oil tankers, offshore platforms, industrial processes, chemical industries, etc.

Equipped with heating, the housing has the same installation and operating temperatures, of between -40° C and + 60° (-40°F / +140°F).

The wiring is made easier thanks to the removable connectors on the circuit board.

The housing can eventually be controlled by VMS through a video encoder with RS485 serial port.
