We, M/s Envirotech Gensets Pvt.Ltd take this opportunity to introduce ourselves as OEM of 'GREAVES' (Erstwhile 'Ruston & MWM') & ESCORTS diesel generating sets from 7.5 KVA to 550 KVA installed in large numbers and working satisfactorily for several specialized and critical installation especially with Defense, Telecom departments, Railways, Industries, Corporate Sectors and various other applications where quality power is required.
The Acoustic Canopies of various makes of DG sets from 5KVA to 1250 KVA are installed & functioning satisfactorily across the length & breadth of the country.
Also Well-established name in manufacturing of Sound Testing Anechoic Chambers & Room Sound Proofing of DG Sets.
Anechoic Chamber / Sound Testing Chamber is required for engineering precision grade sound power measurement. Such a chamber consists of a high insertion loss outer envelope constructed of modular steel Panels with an interior cladding of specific sound absorbing material in multi layers on roof, walls and floors.

These Chambers find their application for sound power testing, sound intensity, where there primary function is to control ambient noise and to increase the accuracy of intensity measurement by reducing sound reflections. Such as in automotive sector, air-conditioner manufacturing units, speaker testing, refrigeration units, fan, motors & compressors manufacturing units etc.

Other environments usually provide a moderate degree of sound isolation at best. Noise from building mechanical systems and here by activities intrude to some degree. The degree of acceptability of the situation depends on the relative levels generated by the equipment under test and the providing ambient. Thus, it's more likely that such a space will be acceptable for a loud sound than for a quiet one.

An Anechoic Chamber / Sound testing Chamber is deigned to provide a normal - incidence sound absorption coefficient greater than 0.99 for all frequencies down to its design cut off frequency. The design and production of effective Anechoic Chamber / Sound testing Chamber is an extremely difficult task and is best left to acoustic chamber manufactures
