Product Description

Main components: 
Hitachi / Copeland EVI R410A compressor
High  efficiency Swep/GEA plate heat exchanger
Saginomiya electronic expansion valves for throttling
Carel pressure transmitters and Saginomiya electronic expansion valve  is adopted  to control  enhanced vapor injection , optimize  performance
Environment friendly R410A refrigerant
Built-in differential pressure flow switch
Carel  controller with user-friendly interface ,easy to understand and operate.
Good look and long lasting galvanized sheet or stainless steel cabinet

Heating and produce hot water (cooling is optional)
EVI models delivers higher capacity at low evaporating temperature thereby better responding to heating requirement thanks to EVI compressor.

PWM circulation pump control, water pump runs as the desired speed, less energy consumption. 
It also results in less supplementary heating to cover the full heating demand on the coldest days.
Workable ambient temperature range - 25℃ to 43℃.
Panasonic EC fan motors. The speed of fan varies so only the required amount of air is utilized. The blades are specially designed to move as much air as possible at the lowest noise level.
Timer ON/OFF
Automatically turn on electric heater in pre-set time period  to heat water up to pre-set temperature to prevent  Legionnella
Antifreeze function and hot gas auto defrosting.
Varied heat curve. Controlled water temperature varies according to ambient temperature
Most components are well sealed to retain heat and prevent dripping.
