Computer Aided Design (CAD)

CAD is the process of drawing and modelling of diagrams and products in either two and three dimensions on a computer package, such as AutoCAD.  This serves many purposes:  in the first instance CAD is used to produce manufacturing drawings of components, which the manufacturer uses to produce components; secondly, these component drawings can be […]

Computational Fluid Dynamics (CFD)

CFD is a branch of fluid mechanics that has application in many fields, such as aerodynamics, weather simulation and environmental engineering. It uses numerical analysis and data structures to analyse and predict outcomes for situations involving fluid flow of either liquid or gas.  The geometry and physical limits of the exercise are usually defined using […]

Comparison : PICV vs DPCV

Pressure Independent Control Valves (PICV) ensure a constant flow, regardless of pressure fluctuations upstream. Each PICV has an internal chamber which is kept at a steady pressure differential relative to the valve outlet. This is done by directing the inlet flow through a set of concentric sleeves before reaching the internal chamber. The sleeve openings […]

Combined Heat and Power (CHP)

Combined heat and power (CHP) is the site generation of electricity and simultaneous use of process heat. It is also known as Cogeneration. Appreciable cost savings can be made by substitution of grid supplies, with by-product heat being captured for site use. The efficiency of fuel usage in CHP is much higher (typically around 90%) […]

Coanda effect

The Coanda Effect was defined by Henri Coandă, who first recognised the phenomenon as, “the tendency of a jet of fluid emerging from an orifice to follow an adjacent flat or curved surface and to entrain fluid from the surroundings so that a region of lower pressure develops.”  AirMasters harness the Coanda Effect not only […]

Closed Protocol

Closed protocol systems are those where the manufacturer withholds all essential supporting technical data. It means that any associated components must be obtained from the same source, effectively restricting customer choice.

Circulator Pump

A circulator pump is a specific type of pump used to circulate liquids, gases or slurries in a closed circuit. A common use is in hydronic HVAC systems (defined as those which use water as the heat exchange medium), circulating hot or chilled water for heating or cooling.  Circulator pumps used in hydronic systems are […]

CIM ball valves

CIM A Series ball valves with extended spindles reduce energy wastage by precise control of flows, which includes quick shut-off. The engineering of these valves is robust, ensuring all benefits are maintained throughout their long service life.  CIM A Series valves are unusual in being made from a solid ball, which eliminates any issues of […]
