Plexus; Star of Chilled Beam Portfolio
Lindab is a market-leading international group which develops, manufactures and markets system solutions for the ventilation industry, offering everything from ventilation components to complete indoor climate solutions. It has approximately 5,000 employees operating in 30 countries worldwide, including Ireland where it has its own, fully-owned company — Lindab (Irl) Ltd : which arose out of its acquisition of; the Aervent Group late last year.
Its product portfolio is extensive, catering for virtually every ventilation and indoor comfort requirement. It is the recognized brand-leader in key market segments, one of them being chilled ceilings where it has pioneered a number of significant industry firsts.
Essentially, a chilled beam is a heat exchanger which transfers the heat from the air in a room to a cooled water circuit. This transfer takes place in two ways —radiation between the surface of the beam and the surrounding surfaces in the room; and by way of convection between the air adjacent to the surface and the surface itself. These two heat transfer values are added together to determine the total heat transfer.
Obviously, the manner in which this process is managed and maximised to deliver optimum performance is quite sophisticated but Lindab is recognised as being at the forefront in developing technologies and system solutions which do just that.
One of the flagship ranges within the Lindab chilled ceiling portfolio is Plexus. The Plexus unit integrates both cooling and heating functions from the climate baffles, together with the supply air terminals technique. A unique feature is that the air is supplied in a 360° pattern instead of a traditional 4-way pattern, which allows for approximately 30% shorter throws
Plexus units are available in many variants to suit most needs for effect and integration in all building types. When comfort is a priority, Plexus I60 which measures 595x595 is suitable as a standard tile replacer, and I120 which measures 1195x595 is suitable as a double tile replacer, both produce effects that are suitable for both small and larger installations. Where large primary air supply is required, the Plexus G/H is the solution. Plexus I and G units are suitable for ceiling-type T15/24 lay-in while Plexus X/H 60 or X120 fits the hidden T-bar or clip-in cassette.
For applications where the project requirements are for a large effect, Plexus M60 is the answer. M stands for magnum and the Magnum unit, with its large battery and lowered faceplate, delivers under the most demanding of situations. It fits ceilings of the T154/24 lay-in type but also comes as a visible unit like the Plexus F60. As standard Plexus is delivered pre-set with a certain air flow by a certain pressure. It comes with selectable side or top connections for both water and air. The unit is ready for use, whether it is for cooling or heating. On arrival at site it only needs to be mounted and thereafter the system started up. Adjustment and commissioning time is minimised.
For service and maintenance all Plexus units are fitted as standard with an inspection and cleaning hatch, and can be fitted with an optional partial detachable battery which makes the process even easier still. Full control of the indoor climate is via the Lindab Regula which controls both heating and cooling actuators sequentially. Regula Combi can be used to control the rooms’ temperature from the one unit. It can also be built in to the Plexus M/F models, or as an external regulator. Regula Secura is provided if the application calls for condensation protection while Regula Connect is used for controlling more than one Plexus unit. Plexus also comes with Drypac, which makes it possible to use very low water temperatures, without condensation.
Full details on Plexus, and the entire Lindab chilled ceiling range, are available with full technical support from Lindab (Irl).
