Description
IBO ITALY SOLAR 19 Diaphragm Expansion Vessel
IBO ITALY solar diaphragm expansion vessels are pressure devices designed for solar installations, used to maintain and equalize pressure resulting from changes in the volume of the heating medium. As the manufacturer, we equip the IBO ITALY Solar series with EPDM diaphragms from an Italian factory and carbon steel bodies coated with epoxy paint, ensuring durable operation under the extreme temperature conditions of solar installations. The series is available in capacities from 8 to 100 liters.

Applications
- Maintaining and equalizing pressure in solar installations with solar collectors – compensating for changes in the volume of the medium resulting from heating.
- Operation with glycol mixtures of up to 50% concentration, used as a heating medium in solar systems.
- Domestic hot and cold potable water installations – maintaining stable operating pressure.
- Solar systems in single-family and multi-family buildings, farms, and public utility facilities requiring pressure compensation.
IBO ITALY solar diaphragm expansion vessels are intended exclusively for media compatible with the technical parameters specified by the manufacturer – detailed operating conditions are set out in the Dambat documentation.
Features, description, and technical data
IBO ITALY solar vessels are a specialized series by Dambat, designed to meet the specific requirements of solar installations, including extreme operating temperatures and the need to work with glycol-based media. The series includes eight models with capacities ranging from 8 to 100 liters, allowing the device to be precisely selected for installations of different sizes.
The vessel body is made of thick carbon steel coated externally with a special anti-corrosion coating and powder epoxy paint, ensuring durable surface protection even under difficult environmental conditions. Inside the steel shell is an EPDM diaphragm manufactured in an Italian factory. This material is highly resistant to temperature and has very low gas permeability, which is crucial for maintaining the long-term tightness of the air cushion in solar installations.
The EPDM diaphragms used are approved for operation with glycol mixtures of up to 50% concentration, making IBO ITALY solar vessels a suitable component of complete collector systems with antifreeze heating media. The long-term maximum operating temperature of the medium is 110°C, while in short-term operation (up to 2 hours) it can reach 130°C, corresponding to solar installation stagnation conditions.
A sealed valve (car tire valve) is located at the rear of the vessel, under the cover, allowing the air pressure to be increased or reduced using a standard compressor. The devices meet the requirements of Pressure Equipment Directive 2014/68/EU.

Frequently asked questions (FAQ) – IBO ITALY solar diaphragm expansion vessels
What are IBO ITALY solar diaphragm expansion vessels used for?
IBO ITALY solar diaphragm expansion vessels are designed to maintain and equalize pressure in solar installations with solar collectors. They compensate for changes in the volume of the heating medium (water or a glycol mixture of up to 50%) resulting from heating, protecting the installation against excessive pressure increases and water hammer.
How do IBO ITALY solar vessels differ from standard IBO ITALY diaphragm tanks and the IPRO FIX line?
The IBO ITALY Solar series was designed specifically for solar installations. The key differences are an approved operating temperature of up to 110°C (short-term up to 130°C) and an EPDM diaphragm adapted for operation with glycol mixtures of up to 50%. Standard IBO ITALY diaphragm tanks (e.g., the GBV series) are intended for general water supply installations without high temperatures, while the IPRO FIX line with a BUTYL diaphragm is dedicated to raw water installations and comes with an extended 5-year warranty.
Are IBO ITALY solar vessels suitable for operation with glycol?
Yes. The EPDM diaphragm used in IBO ITALY solar vessels is approved for contact with glycol mixtures of up to 50% concentration, commonly used as an antifreeze heating medium in solar collector installations. This is one of the key features distinguishing this series from diaphragm vessels intended exclusively for water.
Where can I buy IBO ITALY solar diaphragm expansion vessels?
As the manufacturer, we do not sell directly online. IBO ITALY solar diaphragm expansion vessels are available from our sales partners, installation wholesalers, and authorized online distributors cooperating with the Dambat brand.
What is the warranty period and where should I report a service issue?
IBO ITALY solar diaphragm expansion vessels are covered by a 3-year manufacturer’s warranty. Dambat is the only authorized service provider – the contact form is available at dambat.pl/pages/serwis.
What maximum temperature can IBO ITALY solar vessels withstand?
The long-term maximum operating temperature of the medium is 110°C. Under short-term conditions, such as during solar installation stagnation, the vessels can operate at temperatures of up to 130°C for a maximum of 2 hours. These parameters correspond to the actual operating conditions of solar collector installations, including those in the Polish climate.
How do I select the right IBO ITALY solar vessel model for my installation?
The IBO ITALY Solar series includes eight models with capacities ranging from 8 to 100 liters. The 8–50 l models are equipped with a ¾" connection, while the 80 l and 100 l models have a 1" connection. The vessel capacity depends on the volume of the heating medium in the installation and the parameters of the pressure system. Detailed guidelines are provided in the Dambat technical documentation.
