Description

BARTEC produces local control stations for use in areas with flammable gases and dusts. Depending on the application area, the control stations are designed with the type of protection “Increased safety” or “Protection by enclosure”.

The explosion-protected local control stations are available in aluminium, polyester or stainless steel. When selecting the version, you can choose between a cabinet with door and an enclosure with screw cover. Control, signalling and display devices and remote I/O systems are installed according to customer specifications. The installation of industrial standard equipment in controls for Zone 22, type of protection t “Protection by enclosure” is possible.

The control elements can also be mounted on a mounting rail or in the front wall. Free installation areas can be designated for the subsequent installation of BARTEC control and signalling devices, which are then sealed using blanking plugs. All explosion-protected local control stations are supplied prewired on terminals.
