Hydrocourse Trench Delivers Aesthetic Efficiency Dunham-Bush Launches New UK Manufactured Chiller Range Dunham-Bush Gives Boost to H&V's Next Generation A comprehensive range of steel spring hangers offering low frequency vibration isolation. Wide load ranges and fixing requirements are catered for. Specialist hangers combining steel springs and rubber elements are available and also higher deflection springs if required. Epoxy powder coated steel frame tested to 5 x rated load. Other steel parts are zinc plated. Colour coded helical steel springs to BS1726 Class B laterally stable with 50% overload capacity. Rubber inserts for high frequency attenuation on type SH also prevent the droprod contacting hanger frame. Captive assembly with droprod connector on Type SH allows pre-compression of spring prior to installation if required. Capable of up to 15° angular misalignment. Can be fitted in drop rod or direct to the supporting structure.

Axial Fans and Fan Coil Units. Any other suspended plant. Leaflet PL007 - Spring Hanger type SH Pipes should be supported on either side of changes of direction and additional hangers used to support heavy fittings and vertical droppers. For larger pipe sizes two hangers can be used at each support position.Versatile is one Irelands leading supplier of Valves ,Decorative valves, Control Valves ,Comisioning Centers ,Pressure Independant Contol Valves for Brands such as ‘Herz’ valves and ‘Poletti’ valves . BIM has arrived – click on the link below for more information Building Information Modelling (BIM) is a process involving the creation, generation, design, revision, construction and management of digital representations of physical and functional characteristics of places, buildings and general infrastructure throughout the planned lifespan of a project. The Model itself is created within a CAD design program that various interested parties are able to access.

Building Information Models (BIMs) are files containing data which can be incorporated into the model and as such can be viewed, exchanged, network or revised in one place. A BIM object is a combination of many things: As only the one Model exists, all interested parties can view the Model and all of them will see the same information, at the same time, but being able to concentrate on the section of the model that is specifically relevant to them. This is crucial, especially if there are any changes made to the Model that could affect how various components relate to each other. Notification of any changes to the various parts (or BIMs) means that all interested parties would be advised in “Real Time” rather than having to wait for a new set of drawings to be made on a conventional CAD system and then issued to the concerned parties.

Generally, they are connected to the ductwork that supplies air to and extracts air from the interior and can provide ventilation, heating, cooling, humidity control and filtration. For more information see Air handling unit. Fan coil units (FCU) consist of only a fan and a heating or cooling element, are located within the space they are serving, and are generally not connected to ductwork. They may either just recirculate internal air, in which case a separate ventilation system is required, or may introduce s proportion of ‘fresh’ air that is mixed with the recirculated air.

Fan coil units can be wall-mounted, freestanding or ceiling-mounted and may be concealed in ceiling voids. They may be controlled by local thermostats or by a building management system (BMS). Due to their simplicity, fan coil units are more economical to install than ducted air handling units. However, they can be noisy and can create vibrations because the fan is in the occupied space. Where fan coil units are supplied with chilled water and hot water from central boilers and chillers they are generally referred to as two pipe (either heating or cooling) or four pipe (both heating and cooling) units. Where the heating and cooling is provided locally, they may be referred to as variable refrigerant volume (VRV) or variable refrigerant flow (VRF) systems. Here, refrigerant is circulated between one or more fan coil units and is connected to an external heat exchanger. These systems may be more prone to refrigerant leakage than units that are connected to hermetically-sealed central chillers.
