A conveyor consisting of a series of slats generally made of metal or wood attached to an endless chain.

A sleeve or pipe of larger diameter installed around a pipeline, intended to protect or guide

A slide valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.

A valve that opens and closes a passageway by sliding over a port.

A ring of conducting material which is attached to and rotates with a shaft, so that the electric current may be transferred to a stationary circuit through a fixed brush pressing against it.

Is a wastewater treatment device used to increase the solids concentration in sludge by removing a portion of the liquid fraction, thus reducing the volume of sludge for subsequent processing or disposal.

A smart meter is an electronic device that records information—such as consumption of electric energy, voltage levels, current, and power factor—and communicates the information to the consumer and electricity suppliers.

A device that measures and communicates water usage from consumer to provider to facilitate water management and proper billing.

A detector that is intended to sense smoke.

A block through which a rope can be reeved without access to an end.

A panel and a photovoltaic module whose main parts are solar cells.

An electromagnetic coil, which is a cylindrical coil, the length of which is much greater than its transverse dimensions and which is used to produce a magnetic field.

A valve that has linear action which is fitted with a solenoid for quick operation.

An analyser intended to determine a mixture of solid particles in liquids or solid or liquid droplets in air.

Is a materials recovery facility that separates co-collected recyclable materials through automated and manual techniques into groupings of like materials so they can be processed and transported to appropriate remanufacturing destinations.

A device decreasing noise in a HVAC system.

A meter intended to measure a sound pressure level.

A physical object that is intended to keep other physical objects at a predefined distance and hence having a spacer function.

A device which removes incandescent particles from a gas stream. Spark arrestors are fitted to vehicles and stationary engines which are operated in potentially flammable atmospheres.

A device that is made as a tool to be used for a special purpose.

An analyser intended to determine specific gravity's of materials. Typically of liquids.

A physical object that consists of two discs with equal thickness and outer diameter connected with a flat bar. One of the discs has a hole, while the other disc is without hole.

A switch intended to give a on/off signal when the speed have reached a pre-set value.
