A physical object intended to reduce a noise level.

An acoustic device producing a loud sound as a signal or warning.

A modular, prefabricated unit consisting of equipment, pipes, instruments, controls, structural elements, and other components mounted on a frame that allows the assembled unit to be easily transported and installed as a self-contained process subsystem.

Device which separates oil from water by mechanically wipe the oil of the water surface.

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 devices that measure and communicate water usage from consumer to provider to facilitate water management and proper billing.

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

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

a set of equipment that is designed to remove hazardous substances quickly and efficiently should they spill.

Is a support structure intended to support a flare or vent pipe.

A filter that is separating solid particles from a fluid by passing the fluid through a wire mesh, screen or metal plates containing perforations or slits.

Is a thermal energy storage system that involves layering water at different temperatures within a storage tank to maximize efficiency in cooling systems.

the part of a power system, concentrated in a given place, including mainly the terminations of transmission or distribution lines switchgear and housing and which may also include transformers.

Is an artefact intended to collect a heavy phase by making use of gravity.

A switchgear and controlgear bearing a set of switches for connecting and disconnecting the various circuits of an electrical system, as of a telegraph, telephone, etc.

A physical object that is a general term covering switching devices and their combination with associated control, measuring, protective and regulating equipment, also assemblies of such devices and equipment with associated interconnections, accessories, enclosures and supporting structures.

A vessel intended to contain fluid for storage. Typically a receiving or collecting function for further distribution. Typically with a vertical and cylindrical or square shape and a flat or conical bottom.

A physical object that converts sound signals into corresponding variations of electric current (or potential), which is transmitted by wire or radio to a distant point where it is reconverted into sound.

A detecting element intended to sense temperature.

Is an artefact that store available energy in a thermal reservoir for later use in heating, cooling, or power generation applications.

A transformer that, by electromagnetic induction, transforms a system of alternating voltage and current into another system of voltage and current usually of different values and at the same frequency for the purpose of transmitting electrical power.
