Adaptation and Environment
- Reduced charge of low-GWP HFO refrigerant R-1234ze, minimizing the CO₂ footprint (99.5% lower GWP than R-134a or R-32).
- Wide equipment operating range.
- Condensing pressure control as standard for year-round operation.
- Latest-generation modular programmable AQUAMATIX Siemens electronic control.
- Adaptability to the installation, offering a wide range of models and options.
Energy Efficiency
- Units with INVERTER screw compressors, external variable-frequency drives and latest-generation shell-and-tube heat exchangers.
- Electronic fans and an electronic expansion valve as standard for minimum energy consumption.
- PANGEA ECO offers very high energy efficiency at partial and full load, reducing operating costs.
Heat recovery
System that uses residual heat from air condensation to heat water for both domestic hot water (DHW) and industrial applications.
- Recovery of up to 100% of the condensation heat.
- Free production of high-temperature hot water with partial recovery of hot gases.
- Reduction of electricity consumption in the hot water production system.
- Reduction of fossil fuels and CO₂ emissions with an efficient and renewable solution.
Reduction of fossil fuels and CO₂ emissions with an efficient and renewable solution.
