Temperature-controlled facilities combine use of high-quality HVAC systems, dehumidifiers, and thermostats to ensure your items are maintained at a steady temperature. Climate-controlled units are typically kept between 55° F and 85° F year-round to protect items that could be damaged by extreme temperatures. The risk of rust and corrosion, yellowing, mildew, mold, vermin infestation and warping are highly minimized in temperature-controlled storage.
