Removax

Gresham’s acquired firebox boiler technology from its licensor-Orr & Sembower Inc., USA for a range of Natural Gas / Oil / Firebox boilers. In 1971.

The advantage of the design is apparent: A large firebox furnace eliminates the "furnace" of a fire tube boiler. Heat is transferred to waterfall "leg" Tubes quickly and efficiently. The Flue Gas then enters second and third pass tubes, economizers.

An extremely safe, reliable and efficient design burns fuel completely, achieving over 99.9% combustion without Oxygen monitoring systems.
