The Crafco Patcher is an oil-jacketed melter specifically designed to melt mastic sealants. The Patcher features digital controls to assure that mastic temperatures are held within specifications at all times. The Patcher has angled and staggered agitation blades which provide superior material agitation and aggregate suspension for a consistent material blend. A 6:1 gear box delivers high torque to eliminate agitation stall when using high-density material. The Patcher is equipped with many safety features, including an automatic shut-off on the lid to prevent injuries during operation. With an array of options – like the heated swivel chute – placing mastic is fast and easy.
