Air-to-water heat pumps for mild climates
30-99 kW 34-107 kW
Adaptation and Environment
- Optimized design of high-performance air-to-water heat pump for warm climates and moderate conditions.
- Equipment with operating range for supplying water at high temperatures up to +70 ºC.
- Available with plate heat exchangers or with shell and tube heat exchangers.
Energy Efficiency
- High energy efficiency at both partial and full loads, reducing operating costs.
- Tandem multiscroll for improved seasonal energy efficiency.
- Electronic fans and electronic expansion valve for minimal energy consumption.
- Partial recovery system that utilizes residual condensing heat to warm water for domestic hot water (DHW) or industrial applications.
