Sunex FISH Carbon S4 – compact, durable composite buffer tanks and drinking water storage tanks (Ultra-light fiberglass composite)

Special note as a drinking water storage tank

The Sunex FISH Carbon S4 also functions as a reliable hot and domestic hot water storage tank.
Capacity: 200 liters with minimal space requirements.

Composite buffer tanks are a modern solution for buffering water in heating systems. Their durability and easy installation are impressive. The inner layer is made of high-density polyethylene, reinforced on the outside with fiberglass composite, ensuring a long service life of the tank without corrosion. Compared to steel tanks, they are much lighter, which simplifies transport and installation. In addition, all connections are located on the top of the tank, allowing the unit to be conveniently installed with various heating systems.

Additional Notes

Important note! 

The installation and commissioning of the devices must be carried out exclusively by specialist personnel. In the event of a complaint, professional installation/commissioning by qualified specialist companies (specialist contractor certificate and special qualification) must be demonstrated. If no proof is provided, all warranty and guarantee claims will expire.

Technical changes and errors reserved! Subject to prior sale! Illustration similar!

Refrigerant leaks contribute to climate change. Refrigerants with a lower global warming potential (GWP) contribute less to global warming in the event of a leak than those with a higher GWP. A leak of 1 kg of this refrigerant would therefore have a greater impact on global warming, proportional to the refrigerant's GWP value, than 1 kg of CO2, over a period of one hundred years. Do not attempt any work on the refrigeration circuit or disassemble the unit – always consult qualified personnel.
