Clamps, wires, spools

Earthing clamps can be used in two configurations – as a set of two simple clamps connected with each other by a spiral cable, or as a connection of the clamp to a earthed container and a ring clamp, which is located at the end of the cable, to a earthing strip.

Simple earthing clamps for single- and two-core cables

Cen-Stat earthing clamps are made of stainless steel, with sharp tungsten carbide teeth, able to break through the paint, laminate, dirt, etc.

Earthing conductors ATEX EX

Earthing conductors are characterised by a very high mechanical resistance. They have a hytrel jacket resistant to chemical and mechanical factors, which allows for their application in difficult conditions occurring in many industries.

Conductor reels

An alternative method for coiled or straight conductors is a reel for carrying away electrostatic charges. It is a very popular method ensuring a reliable connection between a ground bus and a container.

Earthing control systems

Earth control systems
with process lock (tanks, big bags)

You can use them in the field of earthing monitoring of e.g. road tankers, railways, big-bags, as well as components of process plants. Earth-Rite systems verify easily and safely that the stored loads are properly discharged to the ground through a monitoring unit with a signal lightning diode. If the earthing is not performed properly, the controllers block the process.

Multiple elements earthing control system

Multiple elements
earthing control system

The MULTIPOINT II system is a device designed to control the earthing of up to 8 self-acting or interconnected system components at the same time. According to the guidelines of international standards for the control of unwanted static discharges, the correctness of earthing will only be confirmed by the system if the resistance of the earthing node on each channel is less than 10 Ω.

Clamps with earthing control

Clamps with earthing control
(IBC tanks, drums, big-bags)

We can offer you clamps with monitoring the state of earthing of barrels, tanks, etc. These solutions, in addition to earthing the equipment operating in production rooms, by means of a monitoring unit with a signalling diode, easily and safely verify that the charges accumulated on the equipment are properly discharged to earth.

The electrified human body is one of the most serious sources that pose a fire or explosion hazard in industrial conditions. An example of a solution that checks footwear for its ability to dissipate electrostatic charges before an employee enters an area with flammable atmospheres is the Sole-Mate shoe control system.
