Zilmet Ultra Inox-Pro Vertical Stainless Steel Expansion Vessel - 10 Bar. - 60Ltr

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.

Mains Liquid Boosting Setup

The MAINSBOOST MB 750SV-1 is intended for 'direct on mains' systems (unvented hot water cylinders and combination boilers) where the incoming mains pressure is greater than 2.5 bar. but the flow is insufficient to meet demand.
MAINSBOOST vessel systems do not require an electrical supply and operate silently.

System cold water storage capacity can be expanded simply by adding one or more MAINSBOOST Add-on pumps as required. 
If the incoming mains water pressure is less than 2.5 bar., a MAINSBOOST Charger pump can be utilised in conjunction with the MAINSBOOST vessel system to boost pressure.

The MAINSBOOST MB 750SV-1 features a nominal vessel size of 750 litres and a pressurised cold water water storage capacity of approximately 412 litres.
Each pump is supplied with a 35mm Upstream Kit (USK) as standard.

Constructed from an epoxy coated steel body and a highly durable virgin butyl diaphragm, all MAINSBOOST vessels are supplied with a 5 year warranty.

The Elbi AFH60 Litre Horizontal Accumulator Pressure Vessel - 60 Ltr - 10 bar. is a Pressure Vessel item. This product is manufactured by Elbi.

The accumulator vessel is a device that fitted into a pressurised water system will provide system water at a pre-set sustained pressure.

Its most common application is to supply systems in which the main supply pressure is too low and a pump is fitted to boost the pressure to an acceptable level.

As system demands take place the accumulator vessel will sustain system pressure by feeding additional water into the system at the required pressure.

This process will limit the number of times the pump needs to start (pump hunting) in order that system pressure remains at the optimal level.

The operating pressure of this is 10 bar.

MikroPro Potable XP Expansion Vessel - 60 Litre Capacity - 10 bar. This range serves heating, chilled and potable (drinking) water systems, with capacities up to 500 Ltrs to suit a wide variety of installations for commercial or residential. This item comes without a wall mount bracket.
