ARMSTRONG FLUID TECHNOLOGY LAUNCHES NEW RANGE OF PRESSURISATION UNITS

Armstrong Fluid Technology has launched the 3760 range of pressurisation units for HVAC applications. For the consultant or M & E contractor the range offers maximum flexibility and space saving options for a plantroom’s specific needs, and for a facility manager, the range is designed to fit and forget. These compact units are designed to maintain the minimum system pressure of sealed systems up to 300,000 litres with some models also offering combined vacuum degassing and automatic chemical dosing as needed. Pressurisation only models are available for both floor and wall mounting, and floor-standing dual/multi models are also included in the range. Each unit combines a range of features to improve efficiency, save money, and reduce maintenance costs.

The 3760 Pro Floor Standing Pressurisation Units are digital units, designed for use on sealed systems, which offer enhanced BMS connectivity for multi-level monitoring. The unit’s controller maintains accuracy at the same time as reducing downtime, as changes can be made on the live system. With built-in dry run protection, anti-seize routine, and flood protection, they notify excessive starts and limit pump run time. These units are available in three models – 2LP, 2MP, and 2HP – with top up delivery pressure ranging from 1-8 bar. There is also the option of the DualSys model, which can control two sealed systems with the same benefits.

In addition to the 3760 Standard PRO models, the range includes ProVDG Pressurisation Units which combine pressurisation and vacuum degassing capabilities. These help prevent damage to pumps, heat exchangers, and valve seals by reducing magnetic accumulation. By effectively removing dissolved gases from the system, they also reduce system resistance and improve pump efficiency, allowing lower operational speeds. This results in improved heat transmission by keeping water at its optimal thermal potential, which saves time and money. These models also feature built-in dry run protection, anti-seize routines, and flood protection, providing notification of excessive starts and optimising pump run time. These units are available in three models – 2MP, 2HP, and 2UHP – with top up delivery pressure ranging from 1-8 bar.

The remaining models in the range are 3760 ProDoseVDG Pressurisation Units. These are 3-in-1 digital units combining pressurisation, vacuum degassing, and automatic dosing capabilities, making them an all-in-one solution for fluid management. They also maintain a minimum system pressure while proportionally providing additive on demand and effectively removing dissolved gases from the system fluid. These models feature built-in automatic chemical dosing capabilities, which enable 100% accuracy according to system requirements. This reduces costs and removes the possibility of human error. A key advantage of this feature is that it helps prevent particulate build-up and reduces costs by removing the need for yearly manual dosing maintenance. With built-in dry run protection, anti-seize routine, and flood protection, they notify excessive starts and limit pump run time. These units are available in three models – 2MP, 2HP, and 2UHP – with top up delivery pressure ranging from 1-16 bar. They are easy to install with a single connection, enabling fit-and-forget convenience.
