Product Details

Premium Evacuated Tube Solar Collector for Efficient Heating

Product Name: High Efficiency Evacuated Tube Collector | Solar Thermal Heating

Welcome to the future of renewable energy heating. Our Evacuated Tube Collector (ETC) is a high-performance solar thermal solution designed to capture maximum solar radiation, even in cold or cloudy climates. Whether you need to heat water for your home, swimming pool, or commercial application, this collector delivers unmatched efficiency and durability.

Unlike flat plate collectors, evacuated tube technology uses a vacuum-sealed layer to trap heat, preventing heat loss and ensuring optimal performance year-round.

What is an Evacuated Tube Collector?

An Evacuated Tube Solar Collector consists of parallel rows of transparent glass tubes. Each tube contains a smaller copper pipe (or heat pipe) attached to an absorber plate. The air is evacuated (removed) from the tube to form a vacuum, which acts as a perfect insulator. This allows the collector to maintain high temperatures even when the outside air is freezing.

Key Features & Advantages

Why choose our Evacuated Tube Collector over other solar thermal systems?

1. Superior Insulation (The Vacuum Effect): The vacuum eliminates conductive and convective heat loss. This means the system works efficiently in sub-zero temperatures, snow, and high winds.

2. High Temperature Output: Capable of reaching much higher temperatures than flat plate collectors, making them ideal for commercial hot water and space heating applications.

3. All-Day Performance: The cylindrical shape of the tubes allows them to capture sunlight from all angles (morning, noon, and afternoon) without the need for expensive tracking systems.

4. Modular Design: If a single tube is ever damaged, it can be replaced easily without draining the entire system or removing the whole collector.

5. Durability: Resistant to corrosion and weather damage, ensuring a lifespan of 15-20 years with minimal maintenance.

Defect:

Non-Pressure,solar water heater system can't work with the situation of one tube break,and have to be maintained at once.

Applications

This Solar Thermal Collector is versatile enough for various uses:

1. Residential Water Heating: Connect to a storage tank to provide hot water for showers and cleaning.

2. Commercial Use: Ideal for hotels, hostels, and hospitals requiring large volumes of hot water.

3. Industrial Pre-heating: Used to pre-heat boiler feed water, saving industrial fuel costs.
