Partel launches decentralised Lunos ventilation system Galway-based company Partel has announced the launch of the Lunos decentralised ventilation system to Ireland. Lunos, founded in 1959, is one of Germany’s fastest growing companies and sells in 26 countries worldwide. “They produce the world’s smallest and most efficient heat recovery ventilation unit. The flagship model the e² can recover up to 99.5% of heat lost and costs less than five euro per year to operate,” said Partel’s Hugh Whiriskey. The award winning e² and Ego systems operate via a regenerative heat exchanger. A ceramic storage element is charged with extract air for 70 seconds, then for the next 70 seconds fresh air is supplied and heated when passing through the storage element. The e² has a very low power consumption of just 1.4 watts in base load operation (0.09 w/m3/h) and an almost silent measuring surface sound pressure level of 16.5 dB(A). The Ego for wet rooms incorporates two fans so that supply and exhaust air can be transferred simultaneously. In early 2014, Partel will launch the Lunos e² Mini, a smaller version of the e² that can be retrofitted
in existing 100mm ventilation ducts. “Our systems are not only duct free but can be used in both new and retrofit construction. They are particularly suited to passive or low energy houses. The systems which are completely hidden in the wall, can be concealed even further externally by using Lunotherm, a system used to conceal external grills in reveals,” Whiriskey said. Lunos have been producing humidity activated decentralised ventilation systems for decades, with whole apartment systems available from just €1,200. Humidity sensitive ventilation can be upgraded to the e² at a later date giving greater flexibility for homeowners. Whiriskey said demand control ventilation systems can operate at up to 91% efficiency and are ideal for large scale developments and retrofits. “They have over 20 million installations and when we visited Lunos in December we were informed of Lunos fans that have been running constantly for over 50 years,” Whiriskey said. In early 2014, Lunos will be launching new whole house touch screen controls that can also control humidity and CO2.
