ULTRA-PRO is appropriate for any modern installation and can be applied to any type of irrigation pump, centrifugal pump and booster sets.

The food grade membrane is replaceable. This product is manufactured by Zilmet. The membrane pressure tank's real volume is superior than that of a normal tank, therefore, it has a smaller footprint at equal water yield, minimum pump starts and is energy saving. The wide range available, the vertical and horizontal version, the galvanised and Stainless Steel connection flange makes Zilmet pressure tanks suitable for any application. The tank is factory tested and certified according to EU directive 97/23/EC. Maximum duration of the membrane is assured as the membrane itself cannot bend or rub against the plate as it is fixed above to the connection and below to the flange.

The tank's lifetime is practically unlimited as the membrane can be replaced.

Built for sealed heating (EN 12828) and chilled-water systems, Flexcon Premium Expansion Vessels stabilise system pressure by absorbing thermal expansion so plant runs safely and efficiently.

A new TPO (thermoplastic polyolefin) diaphragm on 1235 Ltrs models delivers high flexibility and extremely low permeability, helping the pre-charge hold for longer. Lighter construction cuts material use and transport emissions; packaging is FSC-certified to reduce CO₂ impact.

• Sustainable design lighter TPO membrane uses up to 50% less material
• Long service life 15-year warranty
• Low permeability pre-charge pressure maintained for longer
• Heating & cooling suitable for LPHW and CHW installations

Vessels comply with EN 13831 and the Pressure Equipment Directive 2014/68/EU. Red epoxy powder coating (RAL 3002). Flexcon Premium 3580 are supplied with feet and a mounting kit.

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.
