Link integrated units
Integrated units with heat pumps, chillers and gas boilers
For heating, cooling and DHW production.
Benefits
RTA Series
- Use: Heating
- Type: Air to water
- Heat transfer fluid: Water
- Heating capacity: From 247,000 to 617,500 Btu/h
- Renewable energy percentage contributing to the total heat output: 38
- Heating efficiency: 129%
- Outlet water temperature: 140 °F
- Main applications: High efficiency medium-low temperature hydronic heating systems: radiant panels, fan coils, swimming pools, industrial heating and residential DHW.
- Main advantage: Savings up to 40% in heating operational costs in comparison with the best gas boilers, due to the energy recovered from a renewable source (air)
