About SavaWatt (UK)
Establish in 1985, Savawatt (UK) commercialize an improve design from NASA (Frank Nola -USA), to provide commercial customers achieving energy efficient & electrical power saving on motor/compressor loads with their trademark SavaPlug & SavaControl. Thousands of customers with more than a million units installed worldwide incorporate with endorsement from independence institution on the effectiveness.

Together with continuous technical enhancement, SavaLight is the newer generation of product design, target to lower electrical consumption in conventional lighting operating using electromagnetic ballast. They are very effective for florescent tube, high-pressure sodium, halogen etc. to cut down electrical consumption with 30% average.

SavaController – for AC motor, air-conditioning compressor, AHU etc.

Picture on riding a bike - unless you want to go flat out, you pedal a bit, freewheel a bit and you use far less energy than just pedaling gently all the time.

SavaController work on the similar fundamental principal – to supply sufficient power to motor (not excessive) to keep the motor in correct operating torque all the time.

After motor load overcome the inertia momentum, SavaControl analyze the back emf from the motor & adjust the correct power deliver to motor.

Especially on part load situation, When SavaControl manage the voltage & current supplying (reduction) to the motor, the following result obtained:

· Motor eddy-current core losses, proportion to the apply voltage - reduce

· Motor winding losses, proportion to the current square (I2) – reduce.


Now less (wastage) power is going into the motor during operation & efficient improve. Also, less wastage power is now generating in the motor & motor runs cooler & the positive cycles continue to maintain & improve motor efficiency & extending motor life span for mid/long run.

The general energy conservation by SavaControl are 15% (3-phase system) & 20% (1-phase system). However, we do not wish to claim this figure as the saving is also dependence on the loading condition of motor.

Some units that we installed in our customers sites record energy saving up to 30% (40% in some installation in Europe).

As we understand the significant of motor design, to oversize motor rating due to the initial start up current, wear-&-tear frictional, changing of loading condition etc. Thus this design practice do allow SavaControl to enhance the efficiency improvement & achieve energy saving.

SavaLight – for Lighting design with electromagnetic ballast operation – florescent tube, High-pressure Sodium, halogen, Metal halide etc.

The principle behind the SavaLight operation is that once the lights strikes and reaches their operating temperatures, normal utility supply voltage is not required, so it can then be lowered to keep the continuous lighting operation. There is a very marginally reducing light output (generally not noticeable by the human eye and would require a light level meter to determine).

By using this technique of voltage control, savings in excess of 25% can be realistically expected and in many cases the savings are in excess of 30%.

As an added bonus, light fitting with lowering operating temperature can expect an increase in life span ~30% longer.

Addition:

Savaplug, SavaControl & SavaLight are the trademark of Savawatt (UK) with product design & manufactured in Savawatt UK factory.

These are devices installed & studied by many independence institution university (Cranfield Institute of Technology states, Staffordshire University [Dr. Sarath B. Tennakoon –Vodafone case study]) on the effectiveness of motor control using SavaController.

I hope the above info not too heavy, yet comprehensive to explain the fundamental operation of SavaControl & SavaLight.

I do not wish to over-claim on the achievement by SavaController & SavaLight. However, in most cases, overall saving for a project installation should allow customers to benefit on electrical energy saving 10%~25%. As the electrical tariff continue to rise, the electrical cost saving will be significantly increase in the mid-long run. Not to forget on the equipment life span extended & result in customers’ maintenance & equipment replacement expense.
