Solar set 3 x SR 30 vacuum tube collector without storage tank

Solar set with 3 WEBER vacuum tube solar collectors SR 30 without DHW cylinder.

SOLAR KEYMARK certified to take advantage of subsidy programmes!

GENERAL INFORMATION

High-quality solar set with 3 solar tube-vacuum collectors SR 30 by WEBER. The set does not include a DHW cylinder.

The assumed collector area provides efficient water heating of approximately 50% of the annual demand. The remaining 50% (winter period) is to be provided using a central heating cooker connected to the upper storage coil or by means of an electric heater.

Installation fluid

The solar fluid is produced on the basis of propylene glycol, which means that it is completely safe for health in the event of any leakage into the drinking water. The fluid is hygienically certified by the National Institute of Hygiene, which is an additional guarantee of a high level of safety. The fluid is supplied in a 10-litre container as a concentrate with a freezing point below -64°C. After dilution with water, up to 30 litres of ready-to-use mixture is obtained, which is sufficient for typical installations.

Solar expansion vessel (expansion tank) 18

Despite appearances, the diaphragm vessel is one of the most important components of a solar installation. The selection of a vessel with too low a permissible operating temperature or too low a permissible pressure can cause frequent operating problems.

The maximum operating temperature of the diaphragm vessel included in the set is 120°C, while the permissible operating pressure is as high as 10 bar, which guarantees high stability of the entire system.

Connection set

The kit is equipped with a system of brass compression fittings to enable efficient and secure connection of the collector to the pipes.

•  1 x Compression elbow with ¾" socket connection for efficient connection to corrugated stainless steel pipes
•  1 x compression cross-connection with ¾" GZ connection for efficient connection to corrugated stainless steel pipes. The connector is equipped with an air vent for easy filling and with an immersion sleeve for the temperature sensor of the controller
• 2 x double clamp connection fi 22

REMARKS: As a standard, in the presented auction we offer a vacuum solar collector complete with an assembly kit for a sloping roof. If you wish to mount the collector on a flat roof, you will need to purchase such a kit or please contact your sales advisor.
