High performance and peaceof mindWhatever the scale of your project, whatever the size of your budget – IMI-Pneumatex has a high-performance pressure maintenance solution to suit your every need.

03

For more than 60 years, IMI-Pneumatex has been a true pioneer in the pressurisation market.

Founded in 1909 in Basel, Switzerland, we have a proven record of innovation and developing products that remain market-leading technologies to this day. This includes the first closed expansion system equipped with a Butyl Bag, which was developed in 1955.

We have never swayed from our belief

that ‘prevention is better than cure’. This is why we continue to seek new and ground-breaking technologies that will keep the HVAC system clean and free from gas, dirt and sludge, ensuring stability, long life and effective pressure control. However, innovation for innovation’s sake is not what we’re about. We work closely with

our customers to understand the challenges they face and work even harder to create pioneering hydronic solutions to satisfy our customers’ most demanding engineering challenges.

Over the decades, we have developed a cohesive and comprehensive family of high-performance pressure

maintenance solutions. With the advanced hydronic knowledge and technical know-how to back-up our products, our customers can obtain the pressurisation device that is right for them, and thanks to our continued support they can rest-assured that they will provide years of long-lasting and high-standard performance.

The secret of our success is built on a simple, solid principle - we build

our systems to last, ensuring optimal performance, reliability and most

importantly, the long-term peace of mind of our customers.

The Butyl Bag Vessel: A quality and durable solution

Our air-proof bag vessels are the hallmark of IMI-Pneumatex and our most robust and efficient solution.

Our heritage vessels are equipped with a bag that contains the expansion water, so it never touches the walls of the vessels. The bag, made from high-quality, vulcanised Butyl, is the rubber with the lowest gas diffusion rate, providing five to ten times higher gas resistance than other conventional membrane materials.

Together, this winning combination helps to avoid corrosion to sustain the water quality of the system and ensure

its pre-set pressure remains stable over the years, resulting in reliable functionality with virtually no need for maintenance.

IMI-Pneumatex guarantees the traditional air-proof standard of our Butyl Bags by means of in-house manufacturing and independent quality control procedures. It comfortably exceeds the requirements of EN 13831. A five-year warranty underlines its impeccable standards.

We are actually the inventors of closed expansion systems with fixed gas cushions and launched the revolutionary Butyl Bag in expansion vessels back in 1955. The product has evolved since, but each vessel is still being constructed according to the fundamentals of the Statico principle to guarantee quality, reliability and durability.

Two technologies – Multiple solutions

07

The Membrane Vessel: An affordable and trusted solution

The membrane vessel comes as a cost-effective alternativeto the Butyl Bag vessel and is a great addition to the IMI-Pneumatex portfolio.

This vessel holds the expansion water and it is the membrane which separates it from the area that contains air. The total surface that is exposed to the area with air is limited to the membrane, hindering the amount of air that can enter.

Another factor that will impact the amount of air that can enter into the system is the diffusion tightness of the membrane’s material. Squeeze’s

membrane is made from SBR, which does not reach the diffusion tightness of Butyl, but it is higher than EPDM – another popular material used in other expansion vessels in the market.

Membrane vessels are a standard technology on the market with comparable functionality and price points. What can differentiate them in terms of performance and durability is

the material of the membrane e.g SBR or EPDM, as well as the quality of their production and the materials used.

Squeeze offers best in class in terms of construction and quality of materials. Manufactured in a world-class factory in Switzerland, its entire production process embodies the renowned Swiss reputation for quality, precision and reliability, guaranteeing its high-precision value.

We have so far trained more than 200,000 HVAC professionals on energy consumption best practices, product selection and system design as well as providing sound, technical support throughout a system’s lifespan.

In order to acquire knowledge that is worth sharing, our global salesforce

and technical support teams have had a vast amount of first-hand, on-site experience involving high-pressure maintenance systems and all types of hydronic distribution projects. We work alongside our customers from the design stage right through to final commissioning to help create compliant, sustainable and highly efficient HVAC installations.

Knowledge is power and we are committed to sharing our industry-leading insight to help our customers achieve their goals.

“IMI-Pneumatex offers a series of vessel’s shapes and sizes that are practical, durable and suitabe for any system’s needs. Some of our Partners still have several old Pneumatex installation from the eighties that are still perfectly functioning.”

Vágó Lajos TA International Service Kft Hungary

But don’t take our word for it; you can hear directly from our customers who have experienced IMI-Pneumatex products and knowledge first-hand:

“IMI-Pneumatex offers top-quality products that have a long expected durability and thanks to the help provided by my sales rep I can be sure to choose the right products for my projects.

In addition, my job has been greatly improved since working with IMI-Pneumatex because I receive no complaints of water loss during the installation.”
