Grundfos GT-H are maintenance-free multi-purpose pressure tanks with a capacity ranging from 2 to 100 litres.
The tanks are designed for a maximum operating pressure between 10 and 16 bar and a maximum liquid temperature of 90 °C.

The tank is a steel pressure tank made of a virgin propylene liner. The tanks have a non-replaceable FDA-approved high-grade butyl diaphragm, which is pre-charged with compressed nitrogen (1.9 bar).

To ensure long-lasting durability, the diaphragm and liner are both reinforced in specific wear areas. All internal parts, including the air valve, are rounded to prevent piercing of the diaphragm in extreme conditions. The water connection uniquely provides a dual water and air seal ensuring a completely leakage-free pressure tank. Combined with booster and irrigation systems as well as thermal expansion and hydraulic hammer arrestors, the tank is appropriate for drinking-water and grey-water applications. It provides optimised comfort and a patented stainless-steel water connection. The tank also features:

GT-HR-100 PN6 R1 V

Grundfos GT-HR are pressure tanks with a capacity ranging from 8 to 1000 litres. The tanks are designed for a maximum operating pressure of 6 bar and a maximum liquid temperature of 90 °C.

The tank is a steel pressure tank with a non-replaceable rubber diaphragm for heating applications. The tanks have a non-replaceable diaphragm, dividing the tank chamber into two compartments: the upper compartment is pre-charged with compressed nitrogen (1.5 bar) while the lower compartment contains the diaphragm itself, which is a polypropylene (PP) liner.

A pressure tank ensures controlled pressure in the water supply and thereby limits the switching frequency of the pump unit in case of low water consumption or loss due to leakage. This ensures increased comfort in your installation by limiting the start and stop frequency of your pump. It also creates a more stable assembly by compensating for pressure drops when a tap is opened, while reducing problems with water hammer in the pipes.

Built for sealed LPHW/CHW systems, this Airfix Expansion Vessel delivers reliable performance with a tidy, installer'friendly form.

For use in potable water, or fresh-water installations.

The Airfix D expansion vessels operate in such a way that the water flows right through and they are continuously flushed with fresh water from the mains.

This prevents tepid, stagnant water from collecting in the vessel in which bacterial growth could occur.

Therefore, users can be assured of high quality potable water.

Applying an Airfix D expansion vessel to a water heater prevents the opening of the safety group or safety valve each time the potable water is heated.

Engineered for day'to'day plantroom demands, it helps maintain stable operation, protects equipment, and simplifies maintenance.

• Reliable absorption of system expansion
• Factory pre-charge for quick commissioning
• Durable diaphragm construction

Pair with suitable isolation, safety devices and treatment to meet site requirements and best practice.
