Introduction to Sundez EVI heat pump
With innovative EVI (Enhanced Vapor Injection) technology, Sundez EVI heat pump is designed for house heating.
It is able to work stable at ambient temperature as low as -25 Deg C, so that to cut down the power bill during heating season.
It is the best eco-friendly solutions to replace the traditional gas or electric boiler for house heating.
Horizontal blower design enables the quiet running and prolongs the life span of the heat pump.
Outdoor unit and indoor unit connected with hidden connector makes good-looking installation.

Standard features
With advanced EVI (Enhanced Vapor Injection) scroll compressor technology and EEV (Electronic Expansion Valve), the heat pump performs the best efficiency in cold area.
> Eco-friendly R410a refrigerant system is extremely high in efficiency and low noise.
> 2-speed blower with wide blade enables large air flow volume but low noise.
> Split system avoids the water piping freezing risk, with all refrigerant piping and power cables hidden at the back.
> It’s very easy and convenient to control the heat pump with controller on indoor unit.
Casing features
> Hot galvanized casing coated with powder painting performs very well in anti-rusting.
> Grey casing looks elegant and dirt-proof.
> Acoustic absorption measures, including compressor vibration reduction, plenty of sound deaden material, and so on, are taken to efficiently cut down the noise impact.
Control Features
> Reliable interactive control system provides with LED indoor backlight controller.
> It is easy to understand and convenient to operate on the controller.
> Timer function enables customized time to start or shut down automatically in order to avoid the electricity peak hours.
> Auto-defrosting function is realized by the controller.
