The Horizontal Jade Economizer is a versatile accessory that fits all 3-5 ton DBC, DBG, DBH, DSC, DSG, and DSH Daikin packaged units. It is designed to provide "free" air conditioning when outside conditions are appropriate. When the outside air is cool and dry, the economizer automatically opens to bring fresh air into a warm interior space, eliminating the need to run the air conditioning on cooler days.
