Thunder is a new energy-efficient air-cooled reversible heat pump with natural refrigerant R-290. It is available in the 40 to 85 kW capacity range and has a seasonal efficiency in heating SCOP (W55) up to 3,63 – exceeding the minimum requirements of the Ecodesign (ErP) directive. The solution has been designed with full-inverter technology on latest-generation scroll compressors and axial fans.
The Thunder guarantees heating, cooling and domestic hot water production up to 75°C and an operating range in heating from -20°C to +42°C ambient air.
The company behind the new unit says Thunder is “perfect both for meeting the minimum requirements for new buildings and for use in refurbishment due to its ability to produce hot water at high temperatures, making it suitable for use as an alternative and replacement for boilers, in combination with classic radiator systems. Thanks to the careful design, the unit delivers a heat capacity very close to the nominal data, even at very cold outside air temperatures.”
Thunder offers three acoustic levels, without varying the size of the unit:
– Acoustic configuration with compressor soundproofing (SC): basic version;
– Silenced acoustic configuration (LN): from -2 to -4 dB (A) less compared to SC version;
– Super-silenced acoustic configuration (EN): from -6 to -10 dB (A) less compared to SC version
Thunder has been designed in full compliance with European safety standards, and additional safety measures such as the ATEX gas leak detector sensor and extraction fan are installed as standard. All components are suitable for the use of R-290 refrigerant.
Modular design
The solution is designed for modularity and the company says dedicated hydraulic connections simplify and speed up the installation phase. Up to six units can be hydraulically connected in parallel and up to 16 units can be managed in a local network.
Product Manager Giuseppe Barreca commented: “Thunder is the optimal solution for pursuing the European decarbonisation goals of the coming years. Thanks to the use of an ultra-low GWP refrigerant such as propane (R-290), and the very high levels of efficiency obtained by adopting full-inverter technology, the unit contributes to the reduction of both direct and indirect greenhouse gas emissions, while guaranteeing maximum comfort and application flexibility.”
