Ibaiondo, specialist in pressure equipment for hydraulic applications and water supply

Founded in 1965, Ibaiondo has grown to become one of the leading European manufacturers of hydropneumatic tanks and expansion vessels. With a solid reputation built over more than 50 years, the company has earned the trust of its customers thanks to its wide range of products and its commitment to quality and service.


Ibaiondo started as a supporting company in the metal stamping and boiler sector in 1965. Over time, the company specialized in the manufacture of hydropneumatic accumulators, expanding its range and modernizing its production methods to meet growing demand.


With a focus on the development and expansion of its product range, Ibaiondo increased the production of tanks and developed new designs for their application in various fields, such as anti-water hammer tanks for hydraulic infrastructures and expansion vessels in heating, solar energy, and cooling systems.


In the last decade, Ibaiondo has focused on addressing the growing needs for energy efficiency in heating and cooling systems. This has led to the creation of inertia accumulators, air and sludge separators, hydraulic compensators, and automatic pressurization equipment.


Currently, the company strives to maintain its position as a leader in the national market and to become an international reference in the field of pressure equipment.

The product catalog of Ibaiondo is divided into the following categories:

  • Hydropneumatic Accumulators: Used in water catchments, installations for drinking water supply, and fire-fighting groups as an essential part of the pressure group.
  • Anti-water Hammer Tanks: Designed to reduce overpressure and depression waves in water conduits.
  • Expansion Vessels: Play an important role in heating and cooling circuits by absorbing volume increases caused by temperature rises.
  • Automatic Pressurization Equipment: Controlled by a compressor, they maintain constant circuit pressure by compensating for volumetric changes due to temperature variations.
  • Inertia Tanks: Designed for cooling systems and heat pumps, they reduce the number of starts and stops of the group during rapid temperature changes.
  • Hydraulic Compensators: Allow hydraulic separation of generation and distribution circuits in heating and cooling systems.
  • Air and Sludge Separators: Eliminate microbubbles of air and sludge sediments in heating and cooling systems.
  • Compressed Air Tanks: Accumulate air and regulate the operation of the compressor in compressed air networks.
