optaMAC Flash Dry Oven

The optaMAC Oven, available in gas or electric, features a 7036 mm (277 in) heated section utilizing 100% convection heat. Heated sections are available in any size at a minimum of 6096 mm (240 in).

Upper and lower ducts use forced convection heat to dry the top and bottom surfaces of the pasted plate without over drying the plate’s center. A 1,750 CFM power-assisted exhaust increases drying efficiency and maintains negative pressure inside the oven. This results in a cooler ambient temperature outside the oven and less distribution of lead into the factory air. In addition, now all ovens feature easy access internal oven clean-out doors.

When the surface-dried plates exit the oven they are fed to a MAC High Speed Stacker with In-Line Aligner, a MAC High Speed Stacker with Stack Aligner Brushing, or shingled horizontally onto an *optional 3 m (10 ft) off-bearing conveyor attached to, and driven by the oven.
