The DYB-VL are sampling and small lots dyeing machines. Designed as a "bridge" between laboratory and production can perform all the technological cycles as the bigger size machines, allowing the same performances concerning dyeing quality, water aned energy efficiency, the chemical recipes can be the same as the big production machines. The DYB-VL uses an exclusive two direction reversing pump, specifically designed for reduced liquour volumes. The unique design of the impeller allows avoid the need for external piping for the flow circulation reverse, resulting in simple and bottleneck-free circuit, allowing to avoid any physical stress on delicate wool fibres, as well as guaranteeing low liquor ratio on cellulosic yarns.
The same features of DYB-V production machines, concerning the optimization of circulation and mixing effects, are obtained in small size context by the exclusive hydraulic circuit and pump. Basing on the selected version, the machine can allow dyeing from the single package, to the complete column, same as used in the production machines. In this respect, DYB-VL can be used to set all the parameters to drive the big size production machines, concerning circulation, temperatures and all the others.
