NO.1 Coil heat exchange technology
heat energy, and the closed heat exchanger is used to exchange heat and take water. Pressurized water does not need to add booster
pump, and the water quality is fresh without secondary pollution.
NO.2 20 second rapid heat exchange
With the rapid heat exchange technology developed by sola sunshine, cold water flows through the stainless steel bellows heat
exchanger for 20 seconds and quickly turns into hot water. And the temperature difference between the water temperature and the
heat medium after heat exchange is 2 ~ 5 . Moreover, the water quality is fresh, does not contain nitrite and Legionella, is not
easy to scale, and can be used as kitchen water.
NO.3 Modular design and expandable water tank
NO.4 Three target coated vacuum tube
1. The water quality fresh and drinkable
Open water tank for heat storage, closed coil for heat exchange and water intake. Sola sunshine 20 second rapid heat exchange technology is adopted. The hot water is ready to use, and the water quality is fresh. It can be used as kitchen water.
2. Constant water pressure
3. Ease of use and maintenance free
The collector uses heat medium water without scaling; The heat exchanger adopts corrugated pipe floating heat exchange to take
water, which is not easy to scale.
The product is simple to operate and easy to maintain.
4. It can be connected with other energy sources
