Clear- Solar: The right choice for your solar water heater. These tanks are designed to withstand the very high temperatures of summer and antifreeze fluids, preventing leaks and damage to the system.
- Heating: Ideal for radiator systems and boilers. It absorbs the pressure created when the water in the heating network heats up, keeping the pressure stable and protecting your pipes from bursts.
- Water Supply: For potable water networks, pressure boosting systems, and boilers. These tanks have special sanitary certifications so they do not alter the clean water, while withstanding the continuous pressure fluctuations created by the pump/pressure system in your home.

- with Fixed Membrane: The membrane is permanently pressed and sealed to the inner walls of the tank during production. It cannot be removed or replaced.
- with Replaceable Membrane: The membrane is secured at the top with a flange (screws). In case of wear or puncture, the membrane can be removed and replaced with a new one, without needing to replace the entire tank.
- Protection against excessive pressure. For heating/radiators (which operate at low pressure), a vessel up to 4 bar is sufficient. For solar systems, boilers, or water supply pressure systems, choose 6 to 10 bar so it can withstand the high pressures of the network.
