Description
DHW expansion vessel 5 BASIC
IBO expansion vessels for domestic hot water. BASIC are expansion tanks intended for hot and cold water installations, used to maintain and equalize the pressure resulting from changes in water volume. As a manufacturer, we design a series of C.W.U. BASIC with a butyl membrane and a carbon steel body covered with epoxy paint, ensuring durable and failure-free operation in water installations. The series is available in capacities from 5 to 50 liters.
For whom
- Water and sewage installation companies – we supply proven, ready-to-install components for hot and cold water installations with full Dambat technical documentation.
- Designers of sanitary installations – we offer vessels with documented pressure and capacity parameters, facilitating the selection and planning of the system.
- Wholesale and technical stores – we make it possible to expand our offer with an economical series of expansion tanks for domestic hot water. available in a wide range of capacities.
- Service technicians and maintenance departments – we provide dishes covered by a 24-month manufacturer's warranty and support from an authorized Dambat service.
Application
- Maintaining and equalizing pressure in hot and cold water installations - compensation for changes in water volume resulting from its heating.
- Operation in installations filled with glycol mixtures at a maximum concentration of 50%.
- Protection of water systems in residential buildings, commercial facilities and industrial installations.
- Cooperation with pumps and pressure systems requiring certified devices in accordance with Directive 2014/68/EU.
Features, description and technical data
IBO DHW series BASIC by Dambat includes expansion vessels for hot and cold water installations, available in capacities from 5 to 50 liters. High quality materials and control at every stage of production ensure repeatability of parameters and long-term operation of the devices.
The body of the vessel is made of thick carbon steel covered with anti-corrosion varnish and external epoxy powder paint, guaranteeing lasting surface protection. Inside the steel jacket there is a butyl membrane, characterized by high tensile strength and very low gas permeability. The membrane completely separates the water from the compressed air bag, protecting the steel body from internal corrosion.
At the back of the vessel, under the cover, there is a sealed valve (car valve) used to control and regulate the initial pressure using a standard compressor. The vessels meet the requirements of the Pressure Equipment Directive 2014/68/EU.
Parameters of the IBO DHW series BASIC:
- diaphragm: YES – butyl
- Gas permeability: very low
- Body: carbon steel coated with anti-corrosion varnish and epoxy powder paint
- Compatibility: Pressure Equipment Directive PED 2014/68/EU
- Approved media: water, glycol mixtures up to 50% concentration
Detailed technical data of individual models (initial pressure, working pressure, dimensions, weight) are available in the manufacturer's technical documentation. Warranty: IBO – 24 months (2 years) manufacturer's warranty. The only authorized service is Dambat.
Frequently asked questions (FAQ) – IBO expansion vessels for domestic hot water. BASIC
What are IBO DHW expansion vessels used for? BASIC?
IBO expansion vessels for domestic hot water. BASIC are designed for hot and cold water installations in order to maintain and equalize the pressure resulting from changes in water volume. The butyl membrane separates water from the airbag, stabilizing the operation of the entire system and protecting it against sudden pressure spikes.
What is the IBO DHW series? BASIC differs from the IBO C.O. series. BASIC and GBV tanks?
IBO DHW BASIC are designed for hot and cold water installations with a butyl membrane. IBO C.O. series BASIC are vessels for closed heating and solar installations with an EPDM membrane and an initial pressure of 1.5 bar. GBV tanks are vertical hydrophore vessels for water supply systems - with much higher capacities and a different scope of application.
Where can you buy expansion vessels from the IBO DHW series? BASIC?
As a manufacturer, we do not sell directly online. IBO expansion vessels for domestic hot water. BASIC are available from our trading partners, installation wholesalers and authorized online distributors cooperating with the Dambat brand.
What is the warranty period and where to report service?
Expansion vessels of the IBO DHW series. BASIC are covered 24-month (2 years) manufacturer's warranty. The only authorized service is Dambat - the contact form is available on the website dambat.pl/pages/serwis.
How to adjust the pre-pressure in IBO domestic hot water vessels. BASIC?
The pressure is regulated by a sealed valve (car valve) located at the back of the vessel, under the lid. Pressure is added or reduced using a standard compressor. The value of the initial pressure should be selected according to the parameters of a specific installation in accordance with the technical documentation of the Dambat manufacturer.
Are IBO domestic hot water vessels? BASIC are suitable for working with glycol?
Yes – IBO expansion vessels for domestic hot water. BASIC are approved for working with glycol mixtures at a maximum concentration of 50%.
What material is the membrane in IBO DHW vessels made of? BASIC?
IBO expansion vessels for domestic hot water. BASIC are equipped with a membrane made of butyl - a material characterized by high tensile strength and very low gas permeability. The membrane permanently separates water from the compressed air cushion inside the tank.
