CEMI has entered into a commercialisation services engagement with Norway based Gupex, to commercialise a game-changing heat-exchanger technology in Canada. CEMI believes that Gupex’s solution is a step-change in the area of greening the process whereby mining companies use propane to heat the winter air for underground mines.
Ventilation exhaust air from the mines is both warm and humid and therefore full of energy. This energy up until now has been released into the environment as waste. Gupex has a cost-effective patented method of recovering heat from this exhaust air and preheating the fresh ventilation air to the mine shaft. “This results in -45% reduction in CO2 related pollution and the system offers an attractive pay-back on capital investment. With a lifetime of over +50 years, the Gupex solution promises reduced environmental impact, savings in propane and electricity consumption.”
