Highline 260i EC Waterside Fan Coil Unit

Features: Electronically Commutated (EC) fan motor Specific Fan Power of 0.16 to 0.34 at NR Insignificant fan heat gain Designed to operate below NR at External Static Pressures of up to 50Pa Variable speed Fan adjustment Ceiling and Underfloor installation Low surface temperature on electric element Low Maintenance Highline 260i EC Waterside Fan Coil Unit

Highline 260i EC Waterside Fan Coil Unit Fan Coil Unit The most popular waterside control fan coil unit in the UK for the past 15 years, now available with EC fans having low Specific Fan Powers. Initially designed to be fitted into a ceiling void, the flexibility also allows the unit to be installed underfloor. Furthermore an alternative to the standard design is the Highline 260d, which incorporates a detachable discharge plenum and enables a more flexible discharge arrangement. Chassis Units are manufactured from 1.0-1.6mm hot dipped galvanised steel and are constructed without the use of self tapping screws. All thermal and acoustic lining is CFC and HCFC free and class O fire rated. All bearings and moving surfaces will operate without requiring further lubrication. All electrical components and electrical wiring comply with the current edition of the I.E.E. regulations. Each unit is factory tested to ensure that it will continue to meet its specified performance with the minimum of maintenance, throughout its life. Fans The fans are of the double inlet, double width centrifugal type. The scrolls are manufactured from galvanised mild steel, complete with forward curved aluminium or galvanised steel bladed impellers. All fan and motor assemblies are statically and dynamically balanced to prevent the transmission of vibration to the fan coil unit casing. Each fan and motor assembly has thermal overload protection fitted, via imbedded thermistors or the commutation electronics. The motors comply to BS 5000-11 and BS EN 60034. The motor frame is totally enclosed and fitted with maintenance free sealed for life ball bearings. Motors are insulated to BS 2757 class B (minimum) and tested to BS EN 61000-3-2 for Harmonic Distortion and BS EN 61000-3-3 for Flicker. Heat Exchangers Coils are manufactured from 0. mm thick solid drawn copper tubes, mechanically expanded into accurately pre-formed collars in rippled aluminium fins. The coils are arranged for single or multicircuit operation via headers. Each coil is fitted with a manual air vent and drain point. All coils are factory tested to a minimum of bar and are suitable for operating pressures of up to 12 bar static head. Coils are fitted with 15 mm o/d plain copper tails. Condensate Drip Tray The condensate drip tray is manufactured from hot dipped galvanised steel, welded at each corner. The tray is then degreased before anti-condensation insulation is applied to all internal and external surfaces. The tray is fitted with 15 mm o/ d plain brass connection (22 mm o/d optional). The tray has a built in gradient to ensure correct drainage of condensate. Temperature Controls (WATERSIDE) Temperature control shall be by modulation of the control valves allowing either chilled or heated water to flow through the appropriate coil. Air Filter Options Mesh Filter - The filter is permanent and is manufactured from a fine woven mesh of galvanised steel wire, welded to a rigid galvanised steel frame. It can be vacuum cleaned in-situ, or periodically removed for washing when necessary Media type filter - Filters are EU2 to Eurovent 4/5 and manufactured from a synthetic media secured to a wire metal frame and fitted with handles for ease of cleaning and replacement. Discharge/ Inlet Plenum The discharge and inlet plenums are attenuated and thermally lined with a CFC and HCFC free class O fire retardant non-migratory foam, which is both vermin and rot proof. The density of the foam is 11 kg/m³ thereby helping to reduce the total weight of the fan coil unit. Electric Heat Element (if required) The element is manufactured from stainless steel sheath with spiral wound stainless steel fins to minimise surface temperature. It is located upstream of the fan(s) to evenly distribute the heat to the final discharge spigots. Each unit shall incorporate a manual reset high temperature cut-out and a Pressure Differential Switch or Current Switch, wired to prevent operation in the event of a fan failure.

The discharge sound power levels shown above are based on all front spigots connected directly to an unlined plenum/grilles and measurements taken 1.5m from grille at 45 o. The NR levels shown above are for guidance only and are based on a typical office layout. We would recommend that advice is taken from an Acoustic Consultant to verify actual project noise levels. To achieve guide NR it is recommended that a maximum velocity of 2.5m/s per outlet is not exceeded.
