Overview
Cooper&Hunter Light Commercial Slim Duct systems deliver an inconspicuous, ducted comfort solution that can be concealed in attics and ceiling crawl spaces—without the energy loss typical of many central ducted systems. This bundle pairs the CH-24MDT-W slim duct indoor unit with the CH-ES24-230VO outdoor condenser as a single-zone system on 208–230V power.
Slim Duct installation can be highly flexible—duct runs can be directed into separate areas while being collectively controlled by a single thermostat/controller, making it a clean option where wall-mounted heads are not preferred.
