WHITE BEAR LAKE, Minn. — Tjernlund Products Inc. of White Bear Lake, Minnesota, offers a pair of unique, energy-saving fans that are capable of automatically and simultaneously ridding basements or other areas of stale, musty, or smelly air and drawing in fresh outside air.
Called “XCHANGER,” the fans come in two styles. Model X2D is designed for mounting directly next to an outside wall, and Model X2R can be connected to the outside intake/supply hood with 6-inch ducts, so it can be installed in a different room than where the outside wall hood is located. Both models feature two reversible 90-cfm fans that can be positioned to move air in either direction. The user has three options: exhaust air from the interior, draw outside air into the home, or reverse one fan for balanced air exchange with no bypass from either airstream.
The company says although the initial cost of the XCHANGER is comparable to a dehumidifier, the dual fans in the XCHANGER use 35 watts of electricity compared to more than 1,000 watts for the typical portable dehumidifier.
In basement applications, the XCHANGER is normally installed through an opening in the rim joist between floor joists. Electrical cords are plugged into a control box that is plugged into a standard electrical outlet. The control senses the amount of humidity and automatically turns the XCHANGER on or off.
Optional control methods for the Model X2D include a wireless switch, a plug-in timer, or plug-in dehumidistat control. The X2R does not include a dehumidistat control so that it can be paired with the type of control that best fits an end user’s needs. For more information, visit www.tjernlund.com.
