This replacement TEG module is specifically designed to be compatible with the Caframo Ecofan. Replacement is quick and easy. FREE DOMESTIC SHIPPING & HANDLING!
This listing is for our 35mm x 35mm TEG Mfg Part: ecofan-x35 We also sell: 30mm, 37mm, 40mm, 50mm & 62mm TEG Modules
This high performance TEG module is specifically designed to fit the CAFRAMO ECOFAN. The TEG module is the device that converts heat to electricity to power the fan motor. A bad or failed TEG module is the most common cause of fan failure.
Just measure your existing TEG module to determine the appropriate size for your application.Caf ramo carfamo Eco-fanâ„¢ Wood Stove Fan Magic Heatâ„¢ Wood Stove Fan Aspen self-powered fanâ„¢ Stovemate Kettle Fanâ„¢ Silent Partner Wood Stove Fanâ„¢ BioLite
GENERAL INFORMATION: Measure your existing TEG module to determine the appropriate size for your application. Select the size you need from one of our listings. Remember to apply a thin layer of thermal grease on both sides of the TEG module prior to assembly for optimum performance. Note: This item is an aftermarket equivalent designed for generating power from waste heat and is designed specifically to be compatible with the CAFRAMO ECOFAN. It may also be suitable for use in any other application where there is a need to generate power from waste heat.
Important Note
Regarding Wood Stove Fans
If
your fan has a defective motor replacing the TEG module (thermo electric
generator) will not fix the problem. The TEG module is the device
which converts heat to electricity. It is sandwiched between the
upper and lower sections of the aluminum extrusions. This allows heat to
flow from the hot base through the TEG module and to the upper fins where the
heat is then dissipated in the air flow. These fans operate in a
high heat environment which is hard on both the motors and the TEG
modules. Both items can and do go bad although the TEG module being
exposed to the highest temperatures is the component that fails more
often. You can test your motor using a common household battery to
determine if it is working correctly before you conclude that the TEG module
needs replacement.
When
replacing the TEG module be sure to apply a thin layer of thermal grease on
both faces of the new TEG module prior to assembly. This high thermal conductivity interface material is necessary to
achieve optimum performance and to extend service life. Thermal grease is generally available at any
store that sells computers and/or computer components. Stores like Best Buy sell thermal grease and
it can also be found online at eBay or many other sites.
Use
a straight edge to apply and spread the thermal grease across the entire
surface of the TEG. I’ve found that
using the edge of a credit card works best.
Gently
press and rotate the TEG against the mounting surface of the top heatsink. This will help “seat” the module with full
surface contact.
Re-wire
the new TEG module to the fan motor.
You can either solder the leads to the fan motor or splice them to the
short length of lead wire left from your old TEG module.
As you re-connect the top half of the fan
assembly (heatsink side) to the fan assembly base make sure you have remembered
to apply thermal grease to the bottom face of the TEG module. Again, gently press and rotate to “seat” the
TEG against the mounting surface. Be
careful not to damage the TEG during the re-assembly process. TEG modules are strong in compression but
they are weak in shear so do not pinch or over-torque. Use a bolt pattern when tightening the two
halves of the assembly together (similar to how you would mount an automobile
tire). This will prevent pinch points
that could fracture the TEG and will result in uniform compression. |
