The Mobile Workstation for Manual Material Applications

Reliable Technology and Compact Construction on a Single Movable Chassis

The DM 70 COMPACT is a low-pressure mixing and dosing machine used for processing one or two components in manual operation for sealing, bonding, and potting. This reliable machine precisely processes and doses liquid, medium, and high viscosity compounds such as polyurethanes, silicones, epoxy resins, or other polymeric reactive materials

Simple Processing

The DM 70 COMPACT allows the operator to perform diverse programming tasks safely and DM 70 COMPACT is based on a non-recirculating system with continuous material dosing by utilizing precision gear pumps. The processed materials are mixed either with the dynamic mixing head MK 50 or alternatively the static mixing head MK 20. All machine components are placed on a mobile chassis enabling easy access to the machine and allowing fast and comfortable completion of service and maintenance work.

Guaranteed Quality

The DM 70 COMPACT mixing and dosing machine processes the used materials with reliable and consistently high production quality. 

The machine control allows the operator to store and monitor the main material-processing parameters, such as material reactivity data. 

In addition, parameters for rinsing or repeat shot dosing and dosing time can be programmed, as well as the material feed quantity and mixing ratio can be variably set.

Flexible Today, Flexible Tomorrow

The DM 70 COMPACT for the processing of one or two material components Processing one or two components with the DM 70 COMPACT permits the manual application of a wide range of materials utilizing a handheld mixing gun, selectable of either the MK 20 or MK 50 mixing head.

The functional design, proven technology and reliable processes guarantee the profitability of your investment. The DM 70 COMPACT as a mobile stand-alone system helps to save space in your production.
