Drive-inn steriliser were developed for cold and hot water, they where implemented with revolving-, sliding- (to the middle) and/or hydraulically lifted doors. Heating changed from the bottom of the steriliser to a seperate heating unit in the middle. Chemical dipping tanks for baskets, cold disinfecting tanks with tilt mechanism. In the 70's to 80's, 3 sons joined the business : Johan, Peter and Ron. They developed: a sorting- "cascade", export clean washing- and inline disinfecting machines. The export washer and disinfection machines were later developed into fully automatic washing, dipping and packing lines, which can recycle washing water. De-stack and stacking machines completed these lines.
The drive-in sterilizer are further developed to disinfection tank with hydraulic hoist and drying system, which operates fully automatic.
