Product Information
Eco-Friendly R290 Refrigerant
R290 distinctive advantages compared to other alternative refrigerants:Improve COP up to 4.8, reducing running costs; Low GWP of 3, exceptionally eco-friendly and benefit to carbon neutrality, curbing global warming; Water temperature can achieve up to 75℃ with higher energy efficiency; Legionella prevention in water temperature up to 65°C and higher; Wide working range from –25°C to +46°C
DC Inverter Technology
Designed to withstand the extremely cold condition, LANSTEP heat pumps have passed the extremely cold operation test, it can stably operate at -25°C, maintain high COP and reliable stability. Different from fixed speed systems, inverters automatically ramps up and down by the variable speed compressor, which means it can adjust the output needed at the lowest energy consumption based on the ambient conditions as well as maintain temperature at the most comfortable level. Therefore, it achieves higher COP, more efficient heating/cooling & hot water even under extremely cold climate, and greatly saves energy costs, cut down electricity bills.
Low Noise Mode, Super Quiet
By LANSTEP upgrade technology and the unique soundproof internal structure design, the sound pressure of Storm Series Air to Water Heat Pump is kept to as low as 38dB(A) at 2.1 meter distance (Min. Flow).
Main Component and Dedicated Structure
LANSTEP Heat Pump is designed with a comprehensive and rigorous logic system, which controlled by the intelligent console software PCBA to increase the security, efficiency and reliability of the unit operation.
