Features

The 8000 Series facilitates easy anti vibration treatment and can be applied directly to the steel base frame, which is integral to the package. The ARMPak and 8000 Series Vertical In-Line packages use Armstrong Vertical In-Line technology.

Because of the direction of the rotational forces and the dynamically balanced impeller the vibration generated from these packages is minimal and as such the units can be installed onto the plant room floor with just neoprene rubber pads inserted between the concrete slab and the package base frame.

The Armstrong 8200 Series ARMPak is available in twin and triple configurations, with fixed or variable speed control. This variety of configurations provides the energy savings of parallel pumping, combined with the reliability of an optional standby pump.

ARMPak is unique amongst other pumping packages with its compact modular design. This interchangeable system allows, for example, a fixed speed ARMPak and a variable speed ARMPak to be connected, creating a packaged pumping and control solution for a constant primary, variable secondary chilled water system.

By interchanging ARMPak units for any desired combination of HVAC pumping system configuration, designers can optimise plant room space. The variable speed ARMPak includes controls with pre-designed terminal block connections for seamless communications between units.

Benefits

Health and Safety issues surrounding the construction of pumping systems are removed by pre-packaging the product offsite. At the factory, equipment can be assembled on modular bases with open access on all sides, and overhead lifting equipment for the movement of large components. It is impossible to replicate this level of control on onsite. By transferring these issues from the customer, the company is providing a significant level of added value in an industry where health and safety (and the monitoring of it) is paramount.

Independent research by BSRIA shows that off-site manufacture of plant rooms can reduce the overall project cost by as much as 24% compared to conventional methods. Off-site manufacture also offers faster assembly and streamlined planning as weather constraints, skills shortages and other issues related to building onsite are removed. The system arrives ready assembled on the day you want it and requires only the minimum time and resource to complete installation and commissioning. This ensures costs and timescales are significantly reduced giving the customer peace of mind.

Risk is shared through the partnering process and is therefore minimised and controlled on behalf of the customer. Building in the factory removes the “unknowns” and reduces the risk of costly on-site delays, waste and rework. This allows the customer to focus time and resources on other important areas within the project and be secure in the knowledge that their product will arrive on time and within budget.
