Air-to-water

Reversible Gas Fired Absorption Heat Pump


For Heating, Cooling and DHW production.

Benefits

  • The heat pump benefits from Robur's Summer Rebate for the USA.
  • Ultra efficient unit: heating efficiency at rated conditions 126%, saving up to 40% in operational costs compared to the best condensing boilers, recovering 34% of renewable energy from the air.
  • With a single machine it is also possible to provide heating, cooling and supplemental Domestic Hot Water.
  • Stable operation down to -20°F: efficiency over 100% even at -4°F.
  • Complete flexibility and modularity: to increase seasonal performance factor and total heating and cooling capacity.
  • 87% reduction in electrical power requirement (0.75 kWe for 120,400 BTU/h of heating output or 57,700 BTU/h of cooling output), compared with traditional electrical compression systems.
  • Single Phase Power.
  • For applications requiring standby power, the electric generator size and electric output will be considerably lower.
  • High Reliability due to few moving parts inside the unit.
  • Easy Maintenance, similar to gas fired boilers.
  • No Water Consumption. No need for cooling tower (no problems associated with legionella).
  • No use of Harmful Refrigerants.
  • Outdoor Installation.
  • No comfort reduction during defrosting cycles: the unit supplies about 50% of its total heating capacity.
