Description
IBO 12 BASIC Domestic Hot Water Expansion Vessel
IBO C.W.U. BASIC expansion vessels are expansion tanks designed for hot and cold water installations, used to maintain and equalize pressure resulting from changes in water volume. As a manufacturer, we design the C.W.U. BASIC series with a butyl membrane and a carbon steel body coated with epoxy paint, ensuring durable and trouble-free operation in water systems. The series is available in capacities from 5 to 50 liters.
Who is it for?
- Water and sewer installation companies – we supply proven, ready-to-install components for hot and cold water installations, with complete Dambat technical documentation.
- Sanitary installation designers – we offer vessels with documented pressure and capacity parameters, facilitating system selection and planning.
- Wholesalers and technical stores – we enable you to expand your product range with the economical C.W.U. expansion vessel series, available in a wide range of capacities.
- Service technicians and maintenance departments – we provide vessels covered by a 24-month manufacturer’s warranty and supported by Dambat’s authorized service center.
Applications
- Maintaining and equalizing pressure in hot and cold water installations – compensating for changes in water volume resulting from heating.
- Operation in installations filled with glycol mixtures at a maximum concentration of 50%.
- Protecting water systems in residential buildings, commercial facilities, and industrial installations.
- Cooperation with pumps and pressure systems requiring certified devices compliant with Directive 2014/68/EU.
Features, description, and technical data
The IBO C.W.U. BASIC series from Dambat includes expansion vessels for hot and cold water installations, available in capacities from 5 to 50 liters. High-quality materials and inspections at every stage of production ensure consistent parameters and long-term device service life.
The vessel body is made of thick carbon steel coated with anti-corrosion varnish and an external powder epoxy coating, guaranteeing durable surface protection. A butyl membrane is installed inside the steel shell; this material is characterized by high tensile strength and very low gas permeability. The membrane completely separates the water from the compressed air cushion, protecting the steel body against internal corrosion.
A sealed valve (automotive valve) is located at the rear of the vessel, under the cover, and is used to check and adjust the pre-charge pressure with a standard compressor. The vessels meet the requirements of Pressure Directive 2014/68/EU.
Parameters of the IBO C.W.U. BASIC series:
- Membrane: YES – butyl
- Gas permeability: very low
- Body: carbon steel coated with anti-corrosion varnish and powder epoxy paint
- Compliance: PED Pressure Directive 2014/68/EU
- Approved media: water, glycol mixtures with a concentration of up to 50%
Detailed technical data for individual models (pre-charge pressure, operating pressure, dimensions, and weight) is available in the manufacturer’s technical documentation. Warranty: IBO – 24-month (2-year) manufacturer’s warranty. Dambat is the only authorized service provider.
Frequently asked questions (FAQ) – IBO C.W.U. BASIC expansion vessels
What are IBO C.W.U. BASIC expansion vessels used for?
IBO C.W.U. BASIC expansion vessels are designed for hot and cold water installations to maintain and equalize pressure resulting from changes in water volume. The butyl membrane separates the water from the air cushion, stabilizing the operation of the entire system and protecting it against sudden pressure spikes.
How does the IBO C.W.U. BASIC series differ from the IBO C.O. BASIC series and GBV tanks?
IBO C.W.U. BASIC vessels are designed for hot and cold water installations and feature a butyl membrane. The IBO C.O. BASIC series consists of vessels for closed heating and solar installations, with an EPDM membrane and a pre-charge pressure of 1.5 bar. GBV tanks are vertical hydrofor vessels for water supply systems, with significantly larger capacities and a different range of applications.
Where can IBO C.W.U. BASIC expansion vessels be purchased?
As a manufacturer, we do not sell directly online. IBO C.W.U. BASIC expansion vessels are available from our trade partners, installation wholesalers, and authorized online distributors cooperating with the Dambat brand.
What is the warranty period, and where should service requests be submitted?
Expansion vessels from the IBO C.W.U. BASIC series are covered by a 24-month (2-year) manufacturer’s warranty. Dambat is the only authorized service provider – the contact form is available at dambat.pl/pages/serwis.
How is the pre-charge pressure adjusted in IBO C.W.U. BASIC vessels?
Pressure is adjusted using the sealed valve (automotive valve) located at the rear of the vessel, under the cover. Pressure is increased or reduced using a standard compressor. The pre-charge pressure value should be selected according to the parameters of the specific installation and the technical documentation provided by Dambat.
Are IBO C.W.U. BASIC vessels suitable for operation with glycol?
Yes – IBO C.W.U. BASIC expansion vessels are approved for operation with glycol mixtures at a maximum concentration of 50%.
What material is the membrane in IBO C.W.U. BASIC vessels made of?
IBO C.W.U. BASIC expansion vessels are equipped with a membrane made of butyl, a material characterized by high tensile strength and very low gas permeability. The membrane permanently separates the water from the compressed air cushion inside the tank.
