Designed for the spaces that matter most
Upflow systems are deployed across a broad range of commercial environments where occupant comfort, acoustic performance, and design integrity are paramount.

Corporate Offices

Open-plan and private offices benefit from displacement airflow that maintains stratified temperature without draught. The Nova and PPD series integrate invisibly into access floor layouts. Low NC-17 noise supports open-plan acoustic comfort.

Data Centres

Under-floor delivery maximises cooling efficiency directly to server racks. The FTU fan terminal handles high-density heat loads up to 1,800 cfm per unit, while VAV control strategies adapt to changing rack loads in real time.

Trading Floors

LTU linear terminals integrate flush into perimeter and workstation access floor layouts with clean architectural lines. Multiple configurations — plenum, ducted, VAV — allow a single product to serve both heating and cooling zones.

Educational Institutions

Low-noise displacement diffusers maintain acoustic comfort below NC-17, supporting concentration and clear speech intelligibility. Ships fully assembled — installation in seconds minimises disruption to ongoing school operations.

Government & Civic

ETL-listed, fully NEC-compliant systems meet the stringent procurement standards of public sector projects. BACnet MS/TP connectivity allows full integration with government BAS infrastructure without proprietary middleware.

Hotels & Hospitality

Custom grille finishes in ten standard colors and bespoke RAL colors match any interior specification. Stainless steel (304/316) grille options meet the hygiene requirements of food service and spa environments.

Healthcare & Labs

Displacement ventilation from the floor up delivers fresh air to the breathing zone first, reducing cross-contamination risk. Tight shut-off dampers and non-binding flow adjustment maintain hygienic air quality at all times.

Retrofit Projects

Ships fully assembled — collapsible retention bars eliminate special tools for installation in existing raised floor systems. No "clear area" required around diffusers makes retrofitting into occupied, furniture-dense spaces straightforward.

Flexible airflow configurations
Upflow terminals support four primary airflow configurations to suit any project requirement.

Plenum Air Only

Simple openings draw conditioned air directly from the raised floor plenum. No valves or ductwork required.

Heating Only

Duct connections supply heated air from a dedicated source, independent of the cooling plenum.

Cooling Only

VAV air valves modulate cooling supply in response to zone demand via BACnet-connected thermostats.

Heating & Cooling

Combined duct connections and VAV valves within a single LTU terminal for full year-round climate control.
