Product Description

Product Description:

This is a pressurized system, with jacketed hot water storage tank and flat panel solar collector combined.We call it compact flat panel pressurized solar water heater.This closed loop system can prevent freezing and scale. Heated glycol-water mixture solution from the collector flows into the tank's jacketed shell heat-exchanger and then returns to the collector after heating up the domestic water.
The enamel is coated inside the water tank Germany with Which is of high corrosion resistance and of (EN12976 Standard)Great pressure bearing.Our Porcelain enamel tanks approved by CE, WATER MARK, ETL, WRAS, EN12977-3The whole system approved by SOLAR KEYMARK Imported blue titanium absorber from Germany withhigh absorptivity(95%) and low heat loss(5%).High purity oxygen-free copper pipes as circulationsystem with high thermal conductivity,anti-corrosionpressure-bearing and longer service life. Low-iron tempered solar glass as cover with 92% transmittance.Our flat panel solar collector approved by SOLAR KEYMARK(EN12975 Standard)

How It Works:
The system operates on the thermosiphon principle, meaning that heat transfer occurs entirely by means of natural convection, without pumps and control units. The solar fluid heated in the collector rises and transfers heat through a highly efficient jacketed shell. High-selectivity harp absorbers are used to guarantee the highest possible solar yield in this system.
