WICU® Solar

WICU® Solar and WICU® Solar Duo are an integrated system, designed by KME, for solar energy heating systems.

WICU® Solar Duo is made up of two perfectly insulated copper tubes (thermal insulation in polyester) wrapped in a polythene tape and includes an electrical wire for powering the probe. The exterior of the system is protected by a very strong low density polythene covering.

Characteristics of the copper tubes

• Manufactured in accordance with European Standard EN 12449
• Physical state: R200 (coils)
• Absolute roughness: e.= 0.0015 mm
• Linear thermal expansion coefficient: 0.0168 mm/m°C
• Do not soften at high temperatures
• Completely impermeable to gases
• Resistant to UV rays

Characteristics of the covering

• Tubes thermally insulated with a double layer of polyester and wrapped with a single layer of polythene tape.
• External protection of low density polythene (PE-LD): Thickness = 1.5 mm
• Thermal conductivity of the polyester insulation: λ≤ 0.037 W/mK
• Thickness of the single layer of polyester thermal insulation: 4mm
• Excellent resistance to external agents
• The system is complete with an electrical wire for powering the probe.
