SERIES PRESSURIZED PACKAGE SYSTEMS

Our Products

The pressurized solar energy package system operates based on natural circulation, eliminating the need for any pumps or similar machinery.

Our systems, functioning in a closed circuit, utilize a solar fluid-water mixture within the solar collector. This mixture, when heated by the sun, decreases in density and begins to rise within the closed circuit towards the section surrounding the tank’s jacket. Here, the solar transfer fluid & water mixture cools down after transferring its heat to the utility water, increases in density, and returns to the solar collectors.

This cycle continues as long as sunlight is present, effectively heating the water in use. In this system, the hot water pressure directly corresponds to the mains pressure and operates at the same level. Closed-circuit pressurized solar energy systems are favored in all climates.

The system's design without an expansion tank provides ease of use without the need for frequent maintenance.
Easy to install, robust, and stylish due to galvanized open profiles and an aluminum carrier stand.
Leak-proof connections between collectors and the boiler are ensured with flexible chrome flex and klingrit gasket connections.
An optional additional heating source, such as a thermostat-controlled electric heater, can be connected.
Dense insulation keeps the water warm even in the coldest conditions.
