Non-Pressurized Integrated Flat Panel Solar Water Heate
This non-pressurized flat solar water heater adopts integrated copper-aluminum absorber core with silver brazed joints, equipped with high-transmittance low iron tempered glass (4/5mm). The whole system works under 0MPa atmospheric pressure, matched with dense PU foam or glass wool thermal insulation to reduce heat loss effectively.
The aluminum frame is treated by electrophoresis for excellent anti-corrosion performance, with complete silicone sealing structure to avoid water leakage. Multiple sizes (2m×1m / 2m×1.5m) are available for families, villas and rural residential buildings, easy installation and long service life.
Features:
· 0MPa non-pressurized design, adapt to rural low water pressure environment
· Copper-aluminum unified absorber core, high heat transfer efficiency
· Low iron tempered glass with 90%+ light transmittance
· Double insulation: glass wool + rigid PU foam, low heat loss
· Electrophoresis aluminum frame, anti-rust & anti-corrosion for coastal areas
Specification:
· Size: 2m x 1m x 70mm/80mm/90mm;2m x 1.5m x 70mm/60mm/90mm
· Material of core: Copper and aluminum unified core, heat pipe
· diameter:22mm/25mm.Few welding line, high intension, and strong pressure resistance.
