What is a recuperator?

With recuperator – or mechanical ventilation system – it is possible to keep the air clean and fresh in the building, while the system prevents the escape of heat energy.

Why is this necessary?

Due to the strict energy standards the newly built buildings are insulated better and because of this, natural ventilation is reduced, so that the exhaust air is not exchanged as appropriate.

Recuperator operation

Opening the doors and windows, the ventilation can be solved, but due to this method, the building loses valuable heating energy. On the other hand, the recuperator’s heat exchanger absorbs the heat energy and returns it to the building.

The types of recuperators

There are also active and passive recuperators. The active systems include a built-in heat pump. Because of the heat pump, the active recuperator’s efficiency is much higher than the passive type. Although the system costs are higher, the investment returns on a long-term.

The advantages of recuperators

• The heating costs could be reduced to 80-70%
• Dust or other contaminants could be filtered
• The pollen filter could reduce allergic reactions
• The constantly rotating air eliminates mildew or fungus
• Since the windows can be kept permanently closed, noise could be reduced significantly
• There is no draft
• Because the system saves energy, reduces exhaust emissions

Magma Energy awarded its first geothermal concessions in Peru

Vancouver, April 14 /CNW/ – Magma Energy Corp. (TSX: MXY) is pleased to announce that it has been awarded two geothermal exploration concessions in Peru, known as Crucero and Loriscota. These concessions cover 37,400 hectares of land in southern Peru and are underlain by young volcanic rocks with numerous hot springs and other promising indicators of large geothermal systems.

During 2011, Magma will conduct geological, geochemical, and geophysical work to advance each concession´s potential for geothermal power production. Magma expects to receive additional Peruvian geothermal concessions during the year.

Dr. Catherine Hickson, Magma´s Chief Geologist and Vice-President Exploration, said, “I am very pleased we have received these long-awaited concessions and can now begin active fieldwork. Peru has promising geology for world-class geothermal systems and I hope we can replicate in Peru the success we have experienced to date in our Chilean projects.”
