Installation fluid

The solar fluid is produced on the basis of propylene glycol, which means that it is completely safe for health in case of possible leakage into the domestic water. The fluid is hygienically certified by the National Institute of Hygiene, which is an additional guarantee of a high level of safety. The liquid is supplied in a 10-liter container in the form of a concentrate with a freezing point lower than -64 °C. After diluting with water, up to 30 l. of ready-to-use mixture is obtained, which is sufficient for typical installations

Diaphragm vessel (expansion tank), solar 18 l

Despite appearances, the diaphragm vessel is one of the most important components of a solar system. Selection of a vessel with too low allowable operating temperature or too low allowable pressure can cause frequent problems in use. The maximum working temperature of the diaphragm vessel included in the set is 120 °C, while the allowable working pressure is as high as 10 bar, which is a guarantee of high stability of operation of the entire system.

Connection kit

The set enables efficient and reliable connection of collectors and pipes. The set includes:

• 2 x compression fittings for connecting collectors together
• 1 x Clamping elbow with a ¾” GZ connection enabling efficient connection with corrugated stainless steel conduits
• 1 x cross-clamp connector with a ¾” GZ connection enabling efficient connection with corrugated stainless steel cables The connector is equipped with an air vent for easy filling and an immersion sleeve for the controller's temperature sensor.
  
  

NOTES:

In order to completely install the solar set, you must obtain, among others, a mounting kit for the collector, solar cables (pipes) and installation fittings necessary to connect the tank to the existing installation. The installation kit is not included as standard due to the need to adapt it to the type of covering and roof slope. You can buy all these products in our online store.
