System Description

SAS Integrated Service Modules (ISMs), sometimes referred to as Multi Service Chilled Beams (MSCB), have at their heart a Chilled Beam, which is enclosed by an architecturally designed metal casing.

ISMs integrate luminaires and other building services into the metal casing. Building services, which can be integrated within ISMs include, but are not limited to: infrared sensors, smoke detectors, fire alarms, voice and data cabling, sprinkler systems and security equipment, such as CCTV. Chilled Beams use water as the heat transfer method and cooling is provided by the pumping of chilled water through the system.

System Features

Design led cooling system
Energy efficient: high operating temperatures and pressure drop
Active or passive cooling
Compatible with ground-sourcing and free cooling technologies
Off-site prefabrication, testing and commissioning available
Integration of services
Flexible in terms of future room layouts
Lack of moving parts, resulting in low maintenance regimes
Facilitates thermal mass cooling

Access

Via hinge-down panels.

Sizes & Shapes

A range of shapes, widths and lengths is available to suit most applications.

Finish

Polyester Powder coated, supplied as standard with a RAL 9010 smooth finish; a fine textured finish (SAS FT), anti-bacterial coating (SAS AB) and other colours are available. See paint finish for a full range of options.

Perforation

For optimum performance an open area of 50% is recommended for passive ISMs, while for active ISMs an open area of 63% is recommended.

Weight

Varies depending on size of cooling element with services integrated and whether it is a passive or active ISM.

Performance Data

ISM with Passive Chilled Beam	Cooling capacity (approx).*
Watts per square metre - area (at 3m centres)	130 W/m²
Watts per metre (W/m) - length	400 W/m

ISM with Active Chilled Beam	Cooling capacity (approx).*
Watts per square metre - area (at 3m centres)	150 W/m²
Watts per metre (W/m) - length	up to 500 W/m

*Performance is dependant on individual system design.

Design & Performance

ISMs are manufactured to meet specific design requirements, as well as strict performance guidelines. They are available in a variety of dimensions and integrate specific building services.

Legislation

Regulations continue to evolve to ensure the energy efficiency of the built environment. Water based ISMs offer reduced whole of life costs, which in turn reduces a building's energy usage and carbon emissions.

Operating Temperatures

The water supply and return temperatures for ISMs are typically between 14°C and 17°C, which allows for free cooling for parts of the year. Energy consumption is less than other cooling methods.

Maintenance costs

ISMs contain no moving parts and the resulting reduction in scheduled maintenance requirements helps to reduce the cost of ownership over the life cycle of this product.

Planning grid / layout integration

ISMs are flexible in term of accommodating future occupant needs, such as partitioning. Module lengths and widths, along with the incorporation of in-fill panels facilitate the reconfiguration of the space at a future date.

Thermal Mass Cooling

The specification of ISMs offer the added benefit of opening a concrete soffit for thermal mass cooling. This is natural process, which absorbs heat during the day and releases it at night when it is not required. This method has the potential of producing a cooling output of 25 W/m².

Comfort Cooling

ISMs generate minimal air movement and noise, especially when compared to mechanical alternatives, increasing occupant comfort and potentially increasing productivity.
