Ceiling-mounted pipe distribution hubs, which can each serve up to 7 Fan Coil Units (FCUs). Commissioning Modules (CMs) are supplied in vapour-sealed rectangular boxes and comprise the following:

• Selectable flushing pathways for ease of commissioning 
• Self-balancing pressure controls between FCU circuits 
• Ultrasonic energy meters for soft landings and in-service monitoring

CMs are offered with multilayer interconnecting piping, either bare or insulated. All component assembly is done at Works, with hydraulic testing completed before delivery. Design support remains available, in the event of future change of use with reconfiguration of FCUs.
