Voltage optimisation

Seriously, voltage optimisation rocks! Voltage management is an umbrella term for various technologies aimed at optimising, stabilising, regulating, or plain reducing the amount of volts needed to run equipment. The implemented measure: Optimizes the operating voltage to the required value...

High-efficient motors

A high-efficiency motor (HEM) is an electric motor than performs above mandatory minimum. New materials, better design, and better manufacturing have led to major improvements in motor efficiency overall. Savings realised by using HEMs can quickly outweigh the purchase and installation costs because...

Motor power optimisers

When running at low load, electric motors are less efficient. A motor power optimiser (also known as load sensing optimisers) could save between 5 % and 15 % on electricity. Motor optimisers are solid-state devices that automatically monitor the load on an electric motor. Under low load conditions...

Variable speed drives (VSDs)

VSDs prove that speed really is relative after all Variable speed drives (VSDs) – also known as drive frequency converters, adjustable speed drives, or inverters – are an increasingly popular measurement and control system in industry. VSDs can adjust electricity supply to an AC induction motor...

Pipework insulation

Insulating the pipework and valves of a hot-water and heating systems could help cut heat loss or heat gain by up to 90 %. In one or two years, the investment could be recovered, and savings made. Take an office working on a single-shift system, for example. Fitting insulation to 100 mm pipework...

Flash-steam heat recovery

Flash steam released from hot condensate can be recovered and applied elsewhere in the plant to maximise overall efficiency. Recovery systems reduce steam-raising costs, utility bills and CO2 emissions, and help achieve significant savings in fuel, water and feed-water chemicals. The return on...

Blowdown heat recovery

On a daily or weekly basis, steam boilers blow down hot water from the boiler to avoid the formation of sludge. Blowdown heat systems can recover much of this waste heat and reuse it. The system is made up of a flash vessel and a heat exchanger. It works best when blowdown is carried out...
