Description

Thanks to the concept of the vacuum tube, heat loss is practically zero.

 

The physical properties of the collector provides the operating principle of thermal diode so that it can provide heat in one direction, from collector to fluid.

 

The vacuum tubes that make up this collector are able to capture diffused sunlight on a cloudy day, allowing the unit to heat the fluid to usable levels.

 

Due to its dry connection, breakage or destruction of the collector is avoided since there is no fluid circulating through the tubes.

 

The aesthetics of the unit lends itself well to an easy integration with the architecture of most buildings.

 

Heat Pipe Technology enables an inclination angle from 15 to 90º, being able to project easily to countless applications such as production of hot water, pool heating, climate control, etc.

 

This collector consists of a series of small, individual boilers (each tube), so that repairs and replacements can be performed easily and inexpensively, simply by replacing the defective tube without stopping the installation.

 

The Heat Pipe collector enables the measuring of the temperature output without needing to install additional elements into the water circuit. It has an opening for inserting the sensor directly into the output.

 

This collector has exceptional qualities to adverse weather conditions, withstanding impacts of hail of 25 mm and winds up to 120 km/h.

 

It consists of 2 concentric tubes of borosilicate glass. These tubes exist between a pressure below 0,001 atmospheres, and there is also an absorbing layer on the inner tube that captures the sun's rays and provides tremendous heat.

 

This system uses a sealed heat pipe containing a nontoxic liquid that vaporizes when heated. The vapor rises to a head where it transfers heat to the fluid flowing around it. As cold water flowes around the hot tube, the cooled vapors inside the tube condense and falls back into liquid form to start the same process again, thus simulating the natural cycle of rain.
