Packaged plant roomsOverview
Armstrong Integrated Systems manufactures all of its plant rooms using 3D modelling. A virtual 3D plant room is e-mailed to the client, who can then oversee the application to identify any potential difficulties.
CAD technology is used to develop the technical drawings before the plant is assembled. 3D and CAD technology enables the company to tailor plant rooms to exact client specifications.
Armstrong also offers a CPD-accredited audio-visual presentation that can be shown to specifiers on or off the company premises.
Composition and manufacture
Armstrong’s plant rooms are manufactured off-site in a manufacturing centre using Lean Manufacture and 5S Workplace Organisation techniques. They have a mild-steel galvanised base frame to BS EN ISO 1461, and are manufactured in accordance with the Pressure Equipment Regulations 1999.
The packaged plant room enclosure comprises a heavy-gauge, mild-steel base frame, hot-dip galvanised to BS EN ISO 1461. A mild-steel galvanised slotted superstructure for rapid attachment of fittings is fitted to the base frame.
The complete structure is designed to accommodate the full operating load of the installed equipment, both point loads and uniformly-distributed loads. Powder-coated double or single-leaf construction doors are available, complete with high-security locks or locks to suit clients’ requirements.
Size and weight
Plant rooms are available in 14 standard self-enclosed sizes. Modular plant rooms are also available, manufactured from any combination of the standard sizes. Non-standard sizes and sizes greater than 4m width can be accommodated; consult manufacturer for details.
Appearance
All plant rooms manufactured by Armstrong are offered in powder-coated paint finishes. Available in 29 Corus HP200 Colorcoat colours with colour-matched walls, roof panels, doors and rainwater pipework (optional). Consult manufacturer for further details.
Non-slip rubber matting is provided, to protect the pre-painted and varnished steel-plate floor.
Effect of fire
The plant rooms conform to Class 1 surface spread of flame to standard BS 476:Part 7:1987, and Class 0 as defined by The Building Regulations.
Moisture properties
Steel doors prevent distortion of doors or frames, as moisture is not absorbed. Plant rooms have insulated floors that prevent condensation, thus protecting the floor plates against corrosion. Ridge ventilation aids the provision of high-level ventilation in accordance with BS 6644:1991.
Thermal properties
LPC 45mm thick composite insulated building panels give a thermal transmittance value of 0.43W/m2K.
HCFC-free urethane core provides an ozone-depletion potential (ODP) of zero.
Durability
Expected performance life of wall and roof panels is 25 years in normal environments.
Sitework
Off-site construction minimises the requirement for work on-site, which reduces health and safety risks, and the risk of the plant being damaged due to inclement weather. Work on-site is also more efficient, with fewer delays to plant assembly.
Cleaning and maintenance
Warranty: minimal maintenance is required for the plant rooms. Fall-arrest system bracketry minimises the risk to health and safety should roof access be required. Armstrong Integrated Systems offers a 10 year guarantee on all UK plant-room enclosures, pipework and valves, subject to client investment in a cost-effective, annual maintenance plan.
A warranty period of 12 months from delivery or 6 months from commissioning is also offered, and Armstrong can attend to site problems within 48 hours. Extended warranties are available on individual system components. Consult manufacturer for further details.
