T-ND-2 Series Hood
T-ND-2 Series
Exhaust-Only Hood
ThermoTek's flagship T-ND-2 series hood is a wall or island canopy, Type I, exhaust-only unit that operates at low CFM. It is ETL Listed for use over 450°F, 600°F, and 700°F cooking surface temperatures.
Offering A Fully Integrated Package, Pre-Engineered For Optimum Performance
  • Exhaust Flow Rates: Superior exhaust flow rates. A 4' Hood can operate at 150 CFM/ft or 600 total CFM.
  • ETL Listed: ETL Listed for use over 450°F, 600°F and 700°F cooking surface temperatures, provides flexibility in designing kitchen ventilation systems. ETL Listed to Canadian safety standards, ETL Sanitation Listed and built in accordance with NFPA 96.
  • Capture and Containment: Insulated, double-wall rigid front has aerodynamic design that reduces radiant heat into kitchen, prevents condensation and provides exceptional capture and containment of cooking vapors. This is accomplished with the signature T-ND-2 "triangle" on the front of the hood’s capture area and the "C-shaped" design of the hood’s capture area.
  • Stainless Steel Construction: Polished stainless steel on the interior and exterior of the front enhance aesthetics. Fully welded and polished front corners.
  • Reduced Weight: Rigid single wall end panels reduce weight.
  • Convenient Design: Factory pre-wired lighting to illuminate the cooking surface is accessible from the bottom of the hood. Easily accessible hanging angles. Will accommodate 16 inch risers.
  • Channels: Hood comes standard with structural channels on top and wrapper channels on the bottom.
  • Grease Extraction: All hoods come standard with a Patent Pending fully welded grease sub-assembly, high efficiency stainless steel baffle filters, and a deep grease trough which allows for easy cleaning. Captrate ComboŽ and Captrate SoloŽ filters are optional.
  • Reduced Lead Times: Produced on a high volume assembly line with a Patent Pending stud welded assembly process reduces lead times.
  • Clearance to Combustibles: Standard built in 3" rear standoff to meet NFPA 96 requirements, when installed in a wall application.
  • Controls: Hoods can be equipped with modular utility cabinets and end standoffs. Optional UL Listed light and fan control switches flush mounted and pre-wired through electrical chaseway.
  • Optional Make-Up Air: Make-up air can be supplied through an optional front and side plenums (T-ND-2 Series with PSP Accessory).
