A physical object that supplies and mixes air to a liquid or solids.
A propeller like device with agitational or rotational movement located in a tank to prevent the content of the tank to build component segments.
A circuit-breaker in which the contacts open and close in air at atmospheric pressure.
A cooler that is intended to use air as the cooling medium.
An electric motor driven by alternating electric current.
A direct current power supply unit for charging batteries.
A dynamic pump that contains impellers provided with vanes to generate centrifugal force to achieve the required pressure head.
A mechanical switching device that at regular intervals interrupts an electric current.
A mechanical switching device having only one position of rest, operated otherwise than by hand, capable of making, carrying and breaking currents under normal circuit conditions including operating overload conditions.
A terminal box that is used as accommodation for control function circuits.
A switchgear and controlgear that is an insulated panel carrying terminals, fuses, etc, for controlling a number of subsidiary electrical circuits.
An energy transducer that transforms non-electric energy into electric energy.
An electric machine for transforming electric energy into mechanical energy.
An electronic converter that changes direct electric current to single-phase or polyphase alternating currents.
A separator intended to remove solids from vapour or liquid.
A detector that is intended to sense a flame.
is a process unit with gentle agitation used to bring together fine particulates in wastewater into larger clumps or flocs through physical contact to enhance the subsequent separation and removal of solids in sedimentation basins.
A detecting instrument intended to measure and indicate flow rate and/or produce a signal which represents the measured flow rate.
A circuit-breaker in which the arc develops in a blast of gas.
A gauge that is intended to display a representation of a measured level.
A functional switch that is intended to give an on/off signal when particulate material or fluid level have reached a pre-set value.
A transmitter that produces a continuous standardized output signal dependent of a received input signal from a level sensor.
An artefact which contains fins or vanes intended to control a flow of air. Typically also to separate water droplets from an air stream.
A valve that is regulated with hand power.
A circuit-breaker in which the contacts open and close in oil.
