Zilmet Hydro-Pro Vertical Expansion Vessel - 10 Bar. - 150Ltr Zilmet HYDRO‑PRO pressure vessels are designed for potable water and booster systems where stable pressure and efficient pump.

Zilmet Cal-Pro Vertical Expansion Vessel - 6 Bar. - 150Ltr Zilmet CAL‑PRO expansion vessels are designed for sealed heating systems to absorb thermal expansion as water temperature increases.

Built for sealed potable hot and chilled water systems in domestic and commercial settings, these Potable Water Expansion Vessels stabilise pressure by absorbing thermal expansion for safe, reliable operation.

A nitrogen pre-charge helps retain set pressure longer, while a single threaded steel connection with plastic insert provides a durable, non-flow-through design. Suitable for central heating, cooling and tap water applications (not for solar collector circuits).

• Nitrogen gas filling for longer pre-charge retention
• Single threaded steel connection with plastic insert (no flow-through)
• Potable use supports domestic hot/chilled water
• Heating & cooling compatible for sealed systems

Designed for long service life with broad operating limits and glycol tolerance for demanding installations.

The HeatWave Vessel - Vertical - 150Ltr is a Pressure Vessel item.

The HeatWave™ series hydronic expansion tanks provide quality protection for closed loop hydronic heating systems from excessive pressure due to thermal expansion.

Easy to install and featuring an incorporated hex nut connection, HeatWave™ tanks feature an air chamber sealed with a brass air valve and O-ring sealed air cap.  developed to be supported by either system piping, wall-mounted bracket (inline models) or be freestanding (vertical model with base), the HeatWave™ has a maximum working temperature of 99° C / 210° F .

The operating pressure of this is 6 bar.

• Diaphragm design
• Patented Stainless Steel (vertical models) or chromed steel (inline models) water connection

• Two-part polyurethane, epoxy primed paint finish
• Leak-free, O-ring sealed air valve cap
• Maintenance Free

Includes & Benefits

The PressureWave Vessel - Vertical - 150Ltr is a Pressure Vessel item.

The operating pressure of this is 10 bar.

• Booster systems
• Well systems
• epoxy primed paint finish
• Leak-free, O-ring sealed air valve cap

Grundfos GT-D are maintenance-free double-diaphragm pressure tanks with a capacity ranging from 100 to 450 litres.
The tanks are designed for a maximum operating pressure of 10 bar and a maximum liquid temperature of 90 °C.

The tank is a steel pressure tank with a patented controlled-action CAD-2 diaphragm assembly, pre-charged to 1.4 bar. The tanks have a non-replaceable, chlorine-resistant 100 % butyl diaphragm with a precision-moulded copolymer polypropylene liner for superior air and water separation. The diaphragm assembly seals water in a truly non-corrosive chamber, while the air chamber is sealed with a fixed O-ring and closed cell foam, which provides long-lasting and service-free durability.

The tank is appropriate for drinking-water applications in combination with installations with booster systems, well systems, irrigation systems, thermal expansion, hydronic heating expansion, hydraulic hammer arresting and clean water backwash for ultra-filtration systems. The tank also features:
