Pressurized U Tube Solar Thermal Collectors For Central Hot Water Systems

U-Tube Evacuated Tube Solar Collector

The U-Tube Evacuated Tube Solar Collector is a pressurized solar thermal collector designed for stable and long-term heat generation. Its U-shaped metal flow channel separates the heat transfer circuit from domestic water, allowing efficient solar heat collection without direct water flow inside the vacuum tubes.

The collector is ideal for centralized hot water systems, commercial buildings, hospitals, hotels, schools, and large-scale solar thermal projects.

Key Features

Pressurized & Stable Operation

The U-tube design supports pressurized operation while keeping water out of the evacuated tubes. This helps reduce the risks of freezing, overheating, scaling, and leakage and improves long-term system reliability.

Efficient Heat Transfer

Solar energy is absorbed by the aluminum fins and transferred rapidly to the U-shaped metal flow channel through high-conductivity materials, providing stable thermal performance under changing operating conditions.

Freeze-Resistant & Durable

The separated heat transfer circuit helps protect the collector in low-temperature environments. Copper and selected alloy materials provide corrosion resistance and thermal stability for long-term operation.

Low Maintenance

The sealed heat transfer circuit reduces the impact of water quality on the collector and helps minimize maintenance requirements during long-term operation.

Flexible & Customizable

The modular structure allows customized dimensions and configurations for different solar array layouts and building requirements. The brushed silver finish also supports architectural integration.

High-Quality Components

1. 3003 Aluminum Fins – High thermal conductivity and corrosion resistance.
2. Copper Flow Channels – Efficient heat transfer with excellent corrosion resistance.
3. Silver-Copper Welding – Strong and durable connections for long-term operation.
