Fernox has launched a new range of air and dirt separators, vacuum degassers, side stream filters and additives, all of which are specifically engineered for commercial HVAC applications, to help extend the lifespan and improve the efficiency of heating and cooling systems. With products suitable for retrofit and new build applications, Fernox is also able to draw on extensive experience and its own laboratory to assist in system diagnosis and selecting appropriate solutions.
In line with the guidance in BSRIA BG50 and BG29, commercial heating and cooling systems in buildings such as hospitals, schools, universities, offices and public buildings must be protected from the damage caused by circulating debris, air in the system and microbiological contamination.
Backed by more than 60 years’ experience in system protection, the Fernox commercial range includes all the high-quality devices and reliable chemical treatments required to address these issues effectively, and to provide continuous protection with minimal intervention. Designed to work optimally together, the range includes air, dirt and combi separators, vacuum degassers, side stream filters, automatic air vents and stainless steel dosing pots.
Among them is the new CC1 Side Stream Filter Air & Dirt 90. Developed to provide high-performance magnetic and fine particulate filtration, air removal, and a chemical dosing unit, it is suitable for commercial closed-loop systems up to 90,000 litres. The robust stainless steel device utilises three different methods to remove contaminants. A powerful magnet captures magnetic debris, and an air vent removes air that would accelerate corrosion.
Crucially, its anti-microbial filter cartridges prevent bacterial contamination and capture non-magnetic debris to ensure a robust, belt and braces approach to system protection.
Helpfully, Fernox offers a range of micron sizes too – down to 0.5 microns depending upon the condition and needs of the system. Finally, the integrated 5.5L dosing pot allows chemicals to be introduced quickly and safely without shutting down the system.
Another key advantage of the CC1 Side Stream Filter Air & Dirt 90 is that the system can remain in operation during servicing and maintenance, as the bypass it is installed on can be isolated while the captured debris is removed from the filter. This makes it ideal for buildings where downtime must be avoided.
Also featuring in the range is the CF1 Magnetic Dirt Separator, which magnetically captures ferrous debris and hydraulically separates non-magnetic sludge effectively. The range of devices also includes the CA1 Air Separator, a high-efficiency deaerator that continuously removes air and microbubbles from closed loop systems.
There is also the CC1 Combi Air & Dirt Separator and CC1 Magnetic Combi Air & Dirt Separator, which serve both functions. To remove dissolved and free gases from the system water there is also the CA1 Vacuum Degasser, a fully automatic solution that uses controlled vacuum conditions to effectively release entrained gasses.
Rob Jacques commercial business development manager at Fernox said: “Based on six decades of experience, we have created an enhanced range of commercial products that work hand-in-hand to prevent and treat corrosion, contamination and aeration to ensure system longevity, reduced costs and minimal disruption to commercial building occupants. The Fernox combination of products, specialist knowledge, and an in-house, UK laboratory to aid with system diagnostics, means we are ideally positioned to help customers select the solution and approach that is appropriate for their site.”
Supplied in pack sizes suitable for larger systems, the Fernox commercial chemical range also includes some of its most trusted formulations. This includes Protector F1 Inhibitor to prevent corrosion and limescale; Alphi-11 Antifreeze Protector for inhibitor protection in systems vulnerable to freezing; Protector + Filter Fluid F9 containing a dispersant to aid effective debris removal; and Biocide F7 to prevent microbiological contamination and biofilm formation in lower-temperature systems. Cleaner F3 is ideal for use as a pre commissioning cleaner, while Power Cleaner F8 is best suited for restoring heavily contaminated systems.
