Absorption Technology Efficiency evolution
A key technology with a great potential for innovation
G.U.E. - Gas Utilization Efficiency
1968 - ACC Gas absorption chiller. ARKLA (Arkansas Louisiana Gas Co.) introduces the first water-ammonia absorption units, with 300,000 pieces sold.
1991 - Robur Corporation was established to acquire absorption technology from Dometic, a company of Electrolux group.
1998 - ACF The gas efficiency in absorption units was improved by 34%. Efficiency was becoming a crucial element.
2002 - GAHP-W LB was introduced to the market: a worldwide innovation. This GAHP version has put Robur into the high efficiency heating market with an efficiency much higher than electric heat pumps and boilers.
GAHP-AR High efficiency Gas Absorption heat pump for alternative heating or cooling. The first reversible Gas Absorption Heat Pump in the world.
2004 - GAHP-A High efficiency Gas Absorption Heat Pump for heating. Heating efficiency higher than condensing boilers. The most efficient product in gas heating sector worldwide.
ACF-HR The unit with heat recovery was developed and introduced to the market. The heat recovery for production of domestic hot water at temperature up to 85 °C makes the unit very competitive: the total efficiency of the unit is up to 173%.
2005 - GAHP-WS and GS High efficiency Gas Absorption Heat Pump for simultaneous production of hot and cold water, ideal for geothermal systems and process applications.
2008 - Modulating and condensing Gas Absorption Heat Pumps.
E3 Solution Hydronic heating system with modulating condensing Gas Absorption Heat Pumps.
