Among the sectors most affected by current transformation processes, HVAC often faces new challenges in terms of environmental sustainability, energy efficiency, and safety. In this context, Fandis presents its latest solution: filter fan units for control cabinets, equipped with ATEX-certified fans, designed for use in systems operating with natural refrigerants such as propane R290.
For over forty years, Fandis has supported the technological evolution of its customers by offering thermal management solutions aligned with market demands and the latest regulatory updates.
Propane R290: a sustainable choice with specific technical requirements
Propane R290 is gaining ground as a practical alternative to traditional fluorinated refrigerants, thanks to its low environmental impact—with a global warming potential (GWP) of just 3—and its wide availability. However, since it is a flammable gas, its use requires components suitable for operation in potentially explosive environment. This calls for careful evaluation by designers, especially for components installed in electrical enclosures integrated into heat pumps or chillers: in the event of a localized leak, the risk of gas ignition must be minimized. Therefore, every element in the HVAC system—including the enclosure ventilation system—must ensure the highest safety standards.
The new filter fan units with ATEX II 3G fans
To meet these needs, Fandis has expanded its range of filter fan units by introducing new models equipped with ATEX II 3G certified fans, compliant with Directive 2014/34/EU and suitable for use in Zone 2 environments, where flammable gases may be present occasionally and for short periods.
These filter fan units are designed to ensure:
- Efficient air extraction from electrical enclosures housing power and control components;
- Continuous or controlled ventilation, capable of minimizing the risk of gas accumulation;
- Reliable performance even in demanding environmental conditions.
Uncompromised safety, even in compact spaces
One of the distinctive features of the new Fandis filter fan units is their compact design, making them easy to integrate even into smaller electrical enclosures. Their compatibility with standard industrial mounting systems and customizable options make these units highly versatile and suitable for a wide range of HVAC systems using propane R290.
The entire range has been engineered for long-term reliability, minimizing maintenance needs and ensuring uninterrupted operation even in high-risk contexts.
A concrete solution for the HVAC industry
The adoption of propane R290 is rapidly expanding in the industrial cooling and climate control sector, driven by the need to reduce emissions and adopt more sustainable technologies. With its new filter fan units with ATEX-certified fans, Fandis provides manufacturers of heat pumps and chillers with an advanced technological solution—compliant with safety regulations, environmentally responsible, and high performing.
