Zubadan – Reliable Performance in Low Temperature Outdoor Conditions New-generation Zubadan*1 provides powerful heating in cold regions. Zubadan’s rated heating capacity is maintained even in outdoor temperatures as low as -15°C*2, guaranteeing total home comfort when you need it most. *1 Zubadan only available on specific models – see specification tables pages 9, 11 and 15. *2 For Zubadan Model PUHZ-SHW112VAA (according to EN 14511). Zubadan Inverter Technology New-generation Zubadan*1 Inverter Technology provides powerful heating in cold regions where heat pump performance can diminish. With Zubadan, rated heating capacity is maintained even in outdoor temperatures as low as -15°C*2, with guaranteed heating operation at -25°C. Zubadan guarantees a warm, comfortable home when you need it most. Furthermore, Zubadan can provide even faster tank heat-up times in low ambient temperatures compared to standard models. Flash Injection Circuit Heat Interchanger (HIC) Injection Compressor Flash Injection Technology The Flash Injection Circuit is an original Mitsubishi Electric Technology. A heat exchange process at the heat interchanger transforms liquid refrigerant into a two-phase, gas-liquid state and then compresses the gas-liquid refrigerant at the injection compressor. This circuit secures a sufficient flow rate of refrigerant for heating when outdoor temperatures are very low. Thanks to an improved heat interchanger and the introduction of a new injection compressor, the Flash Injection Circuit is now more powerful then ever.
