Built for the North American MarketVolcano Series combines ETL and AHRI certifications with R454B refrigerant and North American operating requirements. As the first Chinese R454B heat pump series to receive cETLus approval from Intertek, it gives brands and distributors a strong foundation for expanding into residential and light commercial heating markets. -
Full DC Inverter EVI TechnologyPowered by a Mitsubishi compressor and Full DC Inverter EVI technology, Volcano Series continuously adjusts its output to match real-time demand. It delivers dependable heating in temperatures as low as -22°F (-30°C), while operating more efficiently under partial-load conditions for stable comfort across the seasons. -
Refrigerant Leakage ProtectionVolcano Series incorporates a dedicated leakage protection design for greater confidence in connected water-based heating systems. If refrigerant leakage occurs, the system is designed to discharge it before it can travel through the water circuit into indoor spaces, adding another layer of protection for residential and light commercial installations. -
Smarter Energy & System ManagementA 5-inch full-colour touchscreen brings system settings, operating status and electricity consumption together in one clear interface. Wi-Fi connectivity, WarmLink app control and the PHNIX IoT platform extend this visibility beyond the equipment, making everyday operation, remote monitoring and service management easier.
