GAHP AR
Reversible absorption heat pump powered by gas and air source renewable energy.
For high efficiency heating and cooling.
Benefits
- Up to 33.3% utilisation of air source renewable energy. Designed to exceed peak efficiencies (GUE - Gas Utilization Efficiency) of 150%, reductions in annual heating costs and in CO2 emissions compared to the best condensing boilers.
- The most beneficial heating system to enhance the energy qualification of buildings, because it permits a considerable promotion of the building's energy classification with the consequent increase in the value of the building.
- Ensures efficiency levels in excess of 130% even at -7 °C. so it is also used in especially cold climates. No back-up systems are required.
- Reduces electricity requirements up to 86% compared to traditional electrical systems, thanks to the prevalent use of natural gas.
- With a GAHP-AR, every year 3.6 Tons of CO2 emissions are saved, which are equivalent to those absorbed by 518 trees or those produced by 2 green cars; every year 1.6 TOE are saved.
Versions
- Available in standard and low-noise version.
- Available also in:
- pre-assembled groups Link on demand: for configurations of more power or combined with Robur gas absorption chillers or condensing boiler;
- Trivalent Integrated Outdoor Package with condensing boiler Gitié ARAY.
Applications
- Ideal for heating and cooling industrial, commercial, accommodation and tertiary utilities, for refurbishment and retrofitting.
- For outdoor installation.
