LECU – LOCAL ENVIRONMENTAL CONTROL UNIT Product Guide


Description The Denco Local Environment Control Unit (LECU) is an intelligent, underfloor air distribution terminal, combining the benefits of displacement ventilation, induction and fan coil technologies. When used in conjunction with Denco Zone units, the area served by each LECU is maintained at occupant-defined conditions, by recirculation of a varying mix of room return and underfloor conditioned air. Requiring only a small single-phase power supply, units can be moved around as required to suit ever-changing office layouts, with no more disruption than that caused by the relocation of a desk. It is this flexibility that offers a real alternative to traditional rigid methods of providing air conditioning within the workspace.

Main Features Airflow: Variable between a nominal 0.1 m3/s giving 1.0 kW cooling at a noise level of NR20

and a nominal 0.2 m3/s giving 2.5 kW cooling at a noise level of NR45. Construction: Components mounted within sheet metal tray, with separate side mounted controls

section. Designed and built in accordance with BS EN ISO 9001. Operation: A modulating damper dictates proportion of room or underfloor air to be supplied,

according to load in the local space, local set point and underfloor air condition. Fans: Dual double inlet, double width forward curved centrifugal fans are directly driven by

a five speed, enclosed motor. Heaters: Although not usually required, the LECU can incorporate a small electric heater

battery to give more precise control. Controls: Units incorporate user-friendly local stand-alone controllers, each complete with large

LCD display. Options are available for networked controls, with or without local display.

Fresh Air: An adjustable orifice gives each LECU a controlled and continuous supply of underfloor oxygenated air at all load conditions, meeting statutory ventilation requirements.

Ancillaries: Air grilles can be supplied to match the height and compliment the colour of any desired floor finish.

Variants: Special “Slimline” units can be supplied using tangential fans, for applications with restricted height raised floor voids.

Local Environmental Control Unit “LECU” The LECU is dimensioned to fit within a standard 600mm x 600mm raised floor tile and can be supplied with matching grilles and surface covering. Units can be positioned as dictated by day-to-day office operational requirements.
