DUBAI, UAE, 17 July 2023: Armstrong Fluid Technology has expanded its portfolio of pressurisation units for HVAC applications. Making the announcement through a Press release, the company said that the new 3760 Pressurisation Unit Range offers a complete suite of products and a combination of features to ensure the effective operation of sealed HVAC systems in large domestic, commercial, or industrial settings. The company added that each model in the range had been engineered with a space-saving design to maximise usable space within the building while ensuring an effortless installation. The company further added that its ‘fit and forget’ design also delivers maximum flexibility, enhanced efficiency and reduced maintenance expenses. 

According to Armstrong, the units will maintain the minimum system pressure requirements by continuously monitoring conditions and logging top-up demand. The company said the 3760 Standard Pressurisation units are available in wall, floor and dual system variants, offering easy commissioning and seamless BMS connectivity, and enabling preventative maintenance, ultimately leading to a longer HVAC system lifespan and yielding cost savings over time. Further, the company added that all three variants of the Standard Pro units are offered in single and twin configurations operating at 50Hz; the Pro 2MP & Pro 2HP models are available at 60Hz to ensure compatibility throughout the GCC region and the top-up delivery pressure ranges from 1-8 bar.

Furthermore, the release said that within the full 3760 Pressurisation Unit Range, all models have built-in dry run protection, anti-seize routine, and flood protection. In addition to this, Armstrong said they provide notifications for excessive starts and optimise pump run time to safeguard the system against wear and tear. The remaining three new units in the range – the ProVDG, the ProDose, and the 3-in-1 ProDoseVDG – are each equipped with enhanced features and capabilities, the company added.

According to Armstrong, the ProVDG Pressurisation unit combines standard pressurisation capabilities with vacuum degassing, helping to prevent damage to the pumps, heat exchangers, and valve seals; the ProDose Pressurisation unit features automatic dosing to maintain minimum pressure while balancing chemical additives with 100% accuracy, and, the 3-in-1 ProDoseVDG combines the features of the units mentioned above, incorporating pressurisation, vacuum degassing, and automatic dosing capabilities.
