Upflow delivers industry-leading underfloor air distribution terminals, linear diffusers, and fan terminal units — engineered for raised access floor environments that demand performance, reliability, and architectural flexibility.
Modular PAP cables enable fast zone installation. DC magnetic motors factory-programmed for multiple control strategies.
Cast aluminum grilles conform to NFPA 90a and are rated to 567 kg — as strong as the floor tile itself.
All Upflow terminals rated ≤ NC-17 across all flow conditions — critical for open-plan offices.
10 standard colors with custom RAL/paint options. Stainless steel (304/316) grilles for premium applications.
VT7200 controller integrates with all major BAS platforms. PI algorithm eliminates temperature offset.

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.
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.
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.
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.
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.
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.
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.
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.
Simple openings draw conditioned air directly from the raised floor plenum. No valves or ductwork required.
Duct connections supply heated air from a dedicated source, independent of the cooling plenum.
VAV air valves modulate cooling supply in response to zone demand via BACnet-connected thermostats.
Combined duct connections and VAV valves within a single LTU terminal for full year-round climate control.
