Is a shaft (civil) intended to transport flue gas to a high location in the atmosphere. It may also be used to supply fresh air via a separate flue.

A choke 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 can be used to obstruct the fluid passing inside, and has the ability to reduce the pressure from the inlet port to the outlet port.

An analysing instrument that applies the principle of chromatography to analyse the molecular composition of a substance.

A mechanical switching device that at regular intervals interrupts an electric current.

A covering or coating applied to a structure to make it weathertight.

A mechanical device made for keeping objects firmly in place or position, temporary or permanently.

A clarifier is a settling tank used to remove suspended solids by gravitational settling and produce clarified liquid as an overflow, especially the removal of flocculated solids in treated wastewater or separation of liquid-solid slurries in chemical and industrial processes.

A classifier is a device that segregates materials into multiple streams according to size, shape, density or other physical characteristics by means of air, vibration, centrifugal motion or inflow.

Any mechanical or electrical device that transmits or modifies energy to perform or assist a cleaning operation in the performance of human tasks.

A net in an open-meshed fabric twisted, knotted, or woven together at regular intervals made for climbing.

An analysing instrument that is intended to determine the cloud point of a fluid.

A transmission that is intended to transmit energy between two shafts providing the capability to connect and disconnect the shafts.

A gravity separator where two liquid substances separates and where the substance with the less gravity can be skimmed off.

The temperature at which either the fuel specimen ceases to flow through a filter within 60 seconds or fails to return into the test jar is recorded as the Cold Filter Plugging Point.

An artefact and a cooling appliance comprising a thermally insulated compartment and a heat pump-chemical or mechanical means-to transfer heat from it to the external environment, cooling the contents to a temperature below ambient.

A support which is a cylindrical or slightly tapering body of considerably greater length than diameter, erected vertically as a support.

Is a device used in pipeline systems to automatically release accumulated air and admit air during negative pressure conditions.

A compactor is a machine or mechanism used to reduce the size of waste material.

A compactor truck is a heavy commercial vehicle equipped with an internally-mounted hydraulic press plate system that compresses, contains, and transports dense refuse, trash, or recyclables.

A device compensating for axial or radial movement between two elements that is connected.

A compost plant is a facility that processes organic matter like food scraps, yard waste, and biosolids through controlled aerobic decomposition into fertilizer or soil amendments suitable for agricultural and gardening applications.

A physical object that is driven by a prime mover by which energy is either constantly or periodically added to an amount of gas in order to increase its pressure.

A physical object that can store data and program(s) that operates on the data. A general purpose computer can be programmed to solve any reasonable problem expressed in logical and arithmetical terms.
