Stack Temp Controller – Complete System

$595.00

Take away all the work and worry of keeping a consistent operating temperature in your wood-fired maple syrup evaporator.  Let the automated Stack Temp Controller from Tetil Engineering do the job for you.  An advanced microcontroller continuously monitors the stack temp using an industrial thermocouple temperature sensor.  Implementing closed-loop control, the microcontroller rapidly checks the difference between the actual temperature and the desired temperature, and makes the necessary speed adjustments to the blower motor.  More air to the firebox means higher temp, less air for lower temp.  The microcontroller makes these adjustments at over 50 times a second, and almost like magic is able to precisely control to the desired temperature.  By controlling the stack temp, the overall arch/evaporator system temperature is controlled.  Better temperature control gives you a more consistent product, uses less wood, and cuts down on boiler time.  And you don’t have to worry about constantly fighting to maintain a stable temperature in your maple syrup evaporator ever again!

Some products on the market simply monitor the stack temp, which is important, but you still have the labor of maintaining the temperature.  Even a master fire tender will experience fluctuations in the tens to hundreds of degrees.  A common solution on the market is an AC blower motor controlled by a rheostat, but this has to be manually adjusted to account for varying wood species and moisture content.  Not to mention, you have to manually adjust for cold loads and re-loads.  The Stack Temp Controller addresses these issues, and more!

ADVANTAGES:

  • Creates a more consistent boil and draw-off.
  • Leads to a more consistent product.
  • Improves efficiency (use less wood).
  • Increases burn time.
  • Reduces boil time.
  • Adapts to different wood species.
  • Adapts to varying moisture contents.
  • Improves cold startup time.
  • Improves re-load recovery time.
  • Can be installed in about 10 minutes.
  • Designed and built in the USA.

FEATURES:

  • Simple easy to use interface.
  • Pluggable components for quick setup.
  • Rugged resistive touchscreen.
  • Touchscreen can be operated with gloves on.

DOCUMENTS:

Extensively tested and tuned for Smoky Lake maple syrup evaporators; however, the Stack Temp Controller uses it’s advanced algorithm to adapt to practically any forced draft evaporator.  This adaptive algorithm has also been proven highly effective for outdoor force draft wood boilers, and will open to that market soon!

4 reviews for Stack Temp Controller – Complete System

  1. D. Peterson, Lowell Vt (verified owner) –

    Installed this system on my 2×4 drop flue pan. Garrett provided excellent support when i needed it. For me the benefits were a much quieter fan, and as noted above, lower stack temps at a given draw off rate. Less wood burned. Worked as promised.

  2. Bulson Rd Natural Sweeteners (verified owner) –

    We are in upstate New York boiling on a Leader 2×8 drop flue w a Revolution syrup pan. The first time boiling with this controller we immediately could see how much smoother and more consistent our draws were. Also, we found we boiled just as hard and produced the same rate of syrup at a 800 degree stack temp as we used to pushing our old fan at max and a 1000 degree stack. Those extra 200 degrees are wasted heat and wood!! Longer more consistent burns between reloading and the confidence of knowing exactly what we have beneath our pans. We run a 430 tap, high vacuum, operation w a 300gph home built RO. This controller takes a pretty efficient hobby setup to the next level! Garret has been extremely patient and helpful correcting an error I made during setup. His customer service commitment and timeliness in responding would be commendable at anytime, but is especially refreshing in the current environment. He has a friend and supporter in us forever!

  3. Steve –

    I was constantly messing with the AC blower that came with my Smoky Lake evaporator. This controller reduced my labor, and I’m using less wood!

  4. Nick –

    Works extremely well, total game changer. Keeps temp spot on and lets me know when wood is needed.
