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
3003 Aluminum Fins – High thermal conductivity and corrosion resistance.
Copper Flow Channels – Efficient heat transfer with excellent corrosion resistance.
Silver-Copper Welding – Strong and durable connections for long-term operation.
Climate-Adaptive Heat Transfer Medium – Selected according to ambient temperature and operating conditions.
The U-tube collector is particularly suitable for cold regions and large solar thermal systems where stable output, low maintenance, and long-term reliability are important.
Why Choose U-Tube Solar Collector?
Pressurized Operation · Freeze Resistance · Stable Heat Transfer · Low Maintenance · Customizable Design
The U-Tube Evacuated Tube Solar Collector provides a reliable solar thermal solution for commercial hot water and large-scale heating applications, with flexible system expansion and architectural integration.
