5. Sealing

Sealing thermoelectrics is key to the success of designs in the field. Condensation can and will corrode the inner materials of thermoelectrics if not properly managed. Sealing can be done at the module and/or system level. Permeability, durability, adhesion, dielectric properties, thermal conductivity and manufacturability affect the sealant choice. Sealant choices could include o-rings, RTV, epoxy, PIB, and combinations of these and other techniques. Please contact the factory to discuss the proper sealing techniques for your specific application.
