Evacuated Tube Collector Sunsystem VTC 15

Discover the future of energy efficiency with the high-efficiency SUNSYSTEM VTC solar collectors with a dry vacuum tube based on innovative Heat Pipe technology. Designed for maximum use of solar energy, these collectors are the ideal solution for anyone looking for a reliable, economical and environmentally friendly way to heat domestic water.

Built to work flawlessly even in the harshest climatic conditions, our collectors guarantee low heat losses and exceptional durability. With them you are not just investing in a product, but in a cleaner future and significant savings on energy bills, gaining comfort and independence.

Heat Pipe technology: the heart of efficiency

At the core of the superior performance of SUNSYSTEM VTC is the patented Heat Pipe technology. Each vacuum tube is a feat of engineering, consisting of two concentric glass tubes with a deep vacuum between them. This vacuum insulation is the key to minimal heat losses, allowing the collector to keep its efficiency even at low outside temperatures.

The inner tube is covered with a special selective layer designed to absorb the maximum amount of solar radiation while minimising heat radiation back to the environment. The result is an exceptionally high efficiency, giving you more hot water with less sunlight.

At the centre of the vacuum tube there is a hollow copper tube, known as the Heat Pipe. A non-toxic fluid circulates in it, which evaporates when heated by the sun's rays and quickly carries the heat to the top of the tube, where it releases it to the heat transfer fluid in the collector manifold. This cyclic process is highly efficient and provides fast and continuous water heating, guaranteeing a constant supply of hot water.

Game-changing advantages:

• Exceptional durability and quality: The vacuum tubes are made of toughened borosilicate glass, which is extremely resistant to mechanical impact, hail and temperature changes. The heat-conducting plates are designed to withstand high stagnation temperatures, guaranteeing a long and trouble-free system life.
• Maximum absorption efficiency: Thanks to the selective coating, our collectors absorb sunlight with maximum efficiency, turning every ray into useful energy for water heating.
• Reliable operation and longevity: The Heat Pipe TU 1 copper heat transfer pipes are made with a minimal number of welds, which ensures perfect tightness and significantly reduces the risk of deposit build-up. The system is designed to operate even with one or more broken tubes, which guarantees uninterrupted operation and peace of mind.
• Flexible and easy installation: With two connections on the header pipe (manifold), which can be connected as heat transfer fluid inlet or outlet in any direction, and a temperature sensor that can be mounted on the left or right, installation is extremely adaptable. The collectors can be mounted on a flat or pitched roof or on a facade. Easy transport, installation and maintenance reduce operating costs and installation time.
• Resistant to all conditions: SUNSYSTEM VTC is built to withstand wind, hail, snow and dust, providing reliable and efficient operation in all seasons, regardless of climatic challenges.
• Scalability and adaptability: You can connect several SUNSYSTEM VTC collectors, which allows you to expand your system as your hot water needs grow or to adapt the capacity to your requirements.

With high-efficiency insulation of the header manifold, these solar systems are designed for maximum heat retention, minimising any loss to the environment. Choose SUNSYSTEM VTC and enjoy the comfort of hot water generated in an ecological and economical way, ensuring reliability and significant savings year after year.
