SAV adds to capabilities of centralised commissioning modules

17 June, 2006

SAV’s centralised commissioning modules can used to control the fan-coil units they serve with the addition of the new SAV Control Commissioning Module.

SAV has added centralised control to its commissioning modules for fan-coil units. By centralising the control capability for up to six fan-coil units at the module, site wiring is simplified — with only a single cable being required to connect to the module to the building-management system. It enables commissioning engineers to perform a range of tasks from a central point. Manufacturers of fan-coil units will not be required to undertake the laborious and costly task of fitting control sets to each FCU. All the waterside and fan-speed controls for up to six FCUs are housed inside the control commissioning module — a 250 mm-deep box that can be located in the ceiling or floor void. Quick-connect plugs link the control module to the commissioning module, and only simple wiring is required to each FCU. The commissioning modules house key components, including multi-port manifold, manual air vent and isolation valves, large strainer with fine mesh and specially designed commissioning valves. The module is connected to the fan-coil units by flexible, multi-layer pipes. Forward and back flushing for the whole system can be carried out from the commissioning module. Flows can be balanced by a single operative. The problem of trapped air is overcome by an air bleed valve in each module.

Government must do more to tackle heat pump and electric vehicle barriers, Which? says

Which? is calling on the government to provide more support for greener home heating and cars, as new research shows cost and other barriers are putting people off making the switch.

New study reveals job stress affects 70% of construction workers

A groundbreaking study conducted by researchers from the University of Cambridge has revealed that at least 70% of people in the construction industry report feeling stressed at work, and this not only has a negative impact on job performance but also personal life. The findings highlight the urgent need for effective strategies to combat workplace stress.
