and we obtained satisfactory results on many
boiler plants where other automatic feed
regulators have failed. Why this result ?

BECAUSE

“ Thermofeed ” Regulators are reliable under any circumstances I

Their efficiency is based on sound mechanical principles only—positive
and direct-acting—though their construction is simple !

They work independently of either temperature or pressures.

Our trained technical experts who specialise in modern
Boiler-house efficiency are always at our clients’ disposal.
Your own and the Empire’s interests demand the highest
efficiency of working plants and liberation of manual
labour which a reliable automatic machine can replace.
