Gomax Quadra: Flexible solutions for reliable connections in AC&R units

In modern AC&R units, system reliability depends not only on the main components, but also on the quality of the connections connecting them. Pressure lines, oil returns, and test points directly impact refrigerant tightness, operational stability, and service continuity.

As systems become more complex and demanding, connections become essential. Compressor vibrations, thermal cycling, and stress can lead to leaks, inefficiencies, or unscheduled maintenance over time.

In this context, designing reliable connections means ensuring durability and reliability throughout the unit's life cycle. This is where a significant part of the efficiency and quality of AC&R systems plays out today.

Gomax: Fluid Expertise Applied to Refrigeration

Gomax was born with a specific goal: to improve the management of connections in AC&R systems by building on consolidated expertise in the transmission of fluids under high pressure and temperature conditions.

Gomax is backed by the experience of Transfer Oil, an industrial company with a long tradition in the design and production of high-performance thermoplastic hoses. This technological heritage allows the transfer of solutions already validated in more demanding application areas to the AC&R world, maintaining an approach focused on quality and long-term continuity.

Flexible pipes for more efficient connection management

Gomax represents an alternative for making connections in AC&R units. Not just a simple component, but a complete system based on flexible thermoplastic tubing, dedicated fittings, and assembly tools.

This approach allows us to overcome the on-site processing logic typical of rigid piping. Connections are made through simple and quick operations, with a direct impact on assembly quality and installation times.

The flexibility of the tube allows the lines to be adapted effortlessly, reducing tension and critical points and contributing to more efficient space management within the unit.

Overcoming the limitations of rigid connections

Traditional connections require processing that introduces variability, lead times, and potential problems. The flexible piping approach simplifies the process.
In particular, it allows you to:

• eliminate welding and brazing, simplifying installation
• reduce risks for the operator, avoiding hot work
• absorb compressor vibrations , limiting stress on the lines
• reduce the risk of cracking, leaks and noise
• reduce installation times , with faster and more standardized operations

The result is a more stable connection, less subject to variability and more consistent with the operational needs of modern AC&R units.

Gomax Quadra range: diameters and applications

The range is structured to cover the main connections within AC&R units, with three diameters that meet specific application needs:

• DN2 (2 mm) for test and control connections, such as pressure gauges, pressure switches and pressure points
• DN4 (4 mm) for instrumentation and oil return lines
• DN6 (6 mm) for high flow oil equalization and return lines

This dimensional logic is accompanied by color coding (orange for high pressure, black for low pressure), which allows for standardized connections and reduces the risk of errors during production and maintenance.
