AET Flexible Space - Underfloor Air Conditioning System Configurations

System Configurations - FlexTouch - Underfloor Air Conditioning - UFAC - Fantile

UfAC Product Overview

Underfloor air conditioning (UfAC) systems make use of the plenum beneath a raised access floor to create the air ventilation zone. Systems are configured according to cooling load requirements and are typically comprised of standard and optional equipment options.

CAM Downflow Unit

The CAM-C / CAM-V delivers conditioned air into the supply plenum and receives return air either from the underfloor plenum (CAM-C) or at high level (CAM-V) for re-conditioning. The units come with a 3-row coil as standard offering cooling capacities from 8-36kW and airflow from 2,130 to 12,010 m3/h. Options include AC or EC fans, 1-row coil for hot water supply, 2 stage electric heater and humidity control.

Fantile (TU4 / TU350)

The Fantile (Fan Air Terminal) is designed to replace a standard 600 mm x 600 mm raised access floor panel and is recessed into the floor. It extracts conditioned air from the plenum below the raised floor and introduces it into the workspace, and also re-circulates room air. Fantiles feature two temperature sensors (floor and room), a motorised damper and the integrated Fatronic controller allows user adjustment of fan speed and temperature. A master-slave function can be configured for large zones with multiple units. Cooling capacity of up to 2.5kW is achieved with a nominal airflow of 500m3/h. Options include standard or slimline units, AC or EC fans, electric trim heaters and hot water coil. A minimum clearance of 180mm is required under the floor.

Console (TUC-500)

A floor standing fan terminal unit designed for areas unsuitable, or with inadequate space for recessed terminals. The unit is positioned over an opening in the raised floor, extracts conditioned air from the plenum and delivers it into the space.

Fresh Air

The fresh air model FA7/FA5 draws additional fresh air from outside and delivers it directly into the CAM to mix with spent air often used when central air treatment plants are not installed. They can also be used in the supply zone to boost airflow within large areas. The unit achieves nominal air flows of 430 m/h and 630 m/h.

Supply Air Grilles

Light aluminium alloy grilles featuring hatch access to the Fantile’s integrated controller. Designed to be part of the walkable surface and height adjustable to fit level with different floor finishes. Circular or custom shape grilles and different colour finishes are available on request.

Return Air Grilles (CAM-C Systems only)

Light aluminium alloy grilles. They are designed to be part of the walkable surface and are height adjustable to fit level with different floor finishes. Different colour finishes are available on request.

Floor Boxes (CAM-C Systems only)

Dust collection trays and acoustic cross-talk attenuators are available to fit underneath the return air grilles. The attenuator design is based on 90° duct bend attenuation effect enhanced by high frequency absorbent lining.

Air Segregation Baffle (CAM-C Systems only)

Fire-resistant and airtight fabric made from glass fibre cloth which is used to divide the underfloor plenum into supply and return air channels.

Raised Access Floor

A raised access floor creates the underfloor plenum which becomes the ventilation zone for the supply (and return) of conditioned air. The substructure must have slotted pedestals and stringers for maximum support and air tightness. 600mm carpet tiles or bonded floor finishes are recommended for future reconfiguration of space.

FlexTouch Controller

Wall mountable, touchscreen remote controller for Fantiles which allows user adjustment of fan speed and temperature and measures CO2 and humidity. PIR sensor detection available. Master-slave function available for large zones with multiple units.

Flexmatic Display

Display unit allowing visual access and control of CAMs, Fantiles and zone communications. The Flexmatic can monitor up to 16 CAM.


All CAMs and Fantiles can work independently or connected in a network. Flexvisor BMS software is available for independent remote monitoring and supervision, with local access using network IP address, or remote access using remote access web address. The Flexgateway interface module can connect the UfAC system to the Flexvisor software, or to a central BMS using either Modbus or BACnet protocol.
