Series 9000 ECT
Extreme Cold Temperature Option


  • In conditions of high relative humidity.
  • If the damper is closed approximately 80 % of the time.
  • When there are extreme temperature differentials.
  • For air intake and exhaust.
  • Where low leakage, maintenance-free dampers are required for ducted, or non-ducted outside walls, or plenums.
  • Caution: In applications where the humidity level is unusually elevated, or where there are extremely high levels of dust and dirt particles, we recommend that the damper linkage and bearing system should be cleaned once a year. This can be done easily with the use of a domestic strength steam cleaner. The loosened dirt and water droplets can then be blown out with compressed air.

   Air leakage:

  • Leakage Class 1A at 1” w.g. static pressure differential. Standard air leakage data is certified under the AMCA Certified Ratings Program.
  • Thermally broken frame, coupled with thermally insulated blades, reduce or eliminate condensation and freeze-up.
  • Aluminum, insulated dampers, installed as “Flanged to Duct” type, create a true thermal barrier between outside air temperature and desired interior temperature.
  • Energy savings are obtained from the resulting thermal efficiency and low air leakage rates.
  • Specifically designed for extreme cold temperatures, below -40°F (-40°C) and down to -100°F (-73°C).
  • Formula for the ECT silicone seals is the same as that used by NASA for its Aerospace program.
  • Constructed with all of the maintenance-free bearing and linkage components of other quality TAMCO products.
    (Caution: Never use any lubricants, such as grease or silicone on TAMCO dampers.)
