Product Description
EVI Air Cooled Scroll Chiller, Air Cooled Scroll Chiller, EVI air cooled modular chiller
Ruidong's EVI Heat Pump is specifically designed to meet the heating and hot water needs of cold climate regions. With the inclusion of air supplementation and enthalpy increase technology, the heat pump effectively increases the exhaust volume of the compressor, allowing it to operate reliably even in low ambient temperatures. This makes it an ideal solution for maintaining room heating and hot water supply in extremely cold climates.
The EVI heat pump is not only efficient but also highly cost-effective. By harnessing free renewable energy from the air, the unit operates with exceptional efficiency, resulting in significantly lower running costs compared to conventional gas boilers or electrical heaters. In fact, its efficiency can be up to 3~4 times higher, making it an environmentally-friendly and economical choice for domestic water heating applications.
Features:
● Eco-friendly refrigerant: R407c.
● Applied range: sanitary hot water, floor heating.
● Enhanced vapor injection famous brand compressor.
● Two speed fan motor: further improve unit operation under high ambient temperature.
● Electronic expansion valve regulates the flow of refrigerant precisely.
● Heat-exchanger cycle technology to further improve operation under low ambient temperature.
● Air exchanger(Fins-coil) with hydrophilic coating.
● Galvanized plate shell, powder coating.
● LCD display wire controller.
● Set the operating time freely.
● Unit runs or stop automatically according to water temperature.
● Control the auxiliary heating (e.g. electric heating).
● With hot water return control, to keep the water warm in supplying pipe.
● Water flow protection control.
● Automatic prevent freezing function in the winter.
● Automatic defrosting.
● Failure diagnosing function.
● Modular design, units combine freely.
