Flame arresters are safety device designed to exitinguish or chek the travel of flame in pipelines and ducts and to prevent flame spreading from them into or put of plant and equipments. Available in sizes from 1″ to 12″ elements are stainless steel with a cast alluminium , carbon steel or stainless steel casing. testing as CMRI standard.


Cable Float Switch is a control device for automatic On/Off pumps, motor and magnetic valves. It is also an alarm device at certain pre-determined surface levels. It is suitable for use in non-flammable liquids at 250 volts. In dangerous environments (e.g. wells and pumping stations) we recommend 24 V voltage. In potentially explosive atmospheres (e.g. oil tanks) the Switch can be used in conjunction with (Ex) I-isolator switch units.


Level switches. work on permanent magnet reed switch basis. The floats which contain permanent magnets move freely between their stops rising or falling with liquid level movement. Hermetically sealed within the tube are reed switches, completely isolated from the medium. The magnet’s field actuates the reed switch as the float moves while the stoppers restrict overrun and prevent the reed switch returning to its original position. Stopper positions should not be changed.
