Dynamic pressure
In a closed, pressurised system with a circulating media, the total pressure consists of two elements; a static pressure and a dynamic pressure.
The operational efficiency of boiler systems that use natural gas as fuel can be improved by utilising the water content of the flue gas.
Efficiency curve
The curve shows the η (efficiency) of the pump. Efficiency is measured in %.
Efficiency performance standards
Efficiency performance standards regulate motor efficiency and stipulate minimum efficiency requirements.
Chlorination is probably the most common method of treating microorganisms in water. Electrochlorination is a safe and simple alternative to chlorine gas and commercial hypochlorite solution.
