From the hopper to the briquette: how the Dinamic 70S turns your waste into resources
A machine designed for those who produce few chips and want maximum efficiency
The Dinamic 70S Briquetting Machine is a Made in Italy hydraulic machine designed to transform wood shavings and dust generated by industrial processes into compact cylindrical briquettes, ready to be reused as fuel or sent to collection centers. It is the ideal choice for small businesses—carpentry shops, woodworking shops, and small workshops—that are looking for a reliable, compact, and easy-to-use solution for everyday operations.
New Technical Improvements Introduced in Version 2026: Why Quality Is Everything to Us
- New anti-return system
The new anti-return system for the lower spoke, unlike the previous one with rod and spring, features a body machined from solid and equipped with an adjustable ball bearing which eliminates wear caused by rubbing. - New magnets
The type of magnets present in the suction area of the hydraulic pump have been replaced with a neodymium model, the best currently on the market, up to nine times more efficient than the current one in order to make oil decontamination even more constant over time due to component wear and oil changes without proper cleaning. - New drawer cylinder stem
The new drawer cylinder stem has been completely redesigned, significantly improving its build quality by replacing the mechanical drawer opening stop, which was very noisy, with a rod limit switch and a solenoid valve for the drawer stop function. We have also optimized the ease of assembly, thus reducing the risk of damaging the seals during replacement. - New Pressure Switches and New Location
Compared to previous models, the new pressure switches are of significantly higher quality and perform much better, with an operating range that has expanded from 50–200 bar to 40 to 400 bar, with precise and simple vernier adjustment—a significant improvement over the previous, less intuitive, and cumbersome screw-type adjustment. Their location has also been changed; previously difficult to access, they are now positioned on the electrical panel bracket for much more practical and functional use. - New general pressure gauge
The new pressure gauge is used to monitor all the machine’s operating pressures during the various work phases (clamp pressure – compaction pressure – general pressure). - Modified clamp opening valve
We changed the vice opening valve from normally closed to normally open to avoid residual pressure in the vice in the event of a power failure. - New power supply specifically for PLC
A new PLC-specific power supply has been inserted inside the electrical panel to adjust the input voltage and avoid any damage due to unregulated currents.
Components and Standard Equipment
Base serving as an oil reservoir, hydraulic cylinder for the drawer, hydraulic cylinder for the compactor, hydraulic system, pressure gauges for the clamp, the compactor, and general pressure, briquette ejection system with a clamp equipped with a hydraulic cylinder and a wear-resistant sleeve, and an electrical control panel with a PLC. Its compact dimensions—1165 × 1640 × 1460 mm for 500 kg—make it easy to install even in confined spaces without requiring dedicated infrastructure. Total installed power: 5.5 kW.
Compatible materials
Wood (all types), paper, cardboard, biomass, plastic, MDF, leather, and many other materials with moisture content between 8 and 17%. For non-standard materials, a free sample test is available at COMAFER’s R&D department.
Measurable operational benefits
Briquetting with the Dinamic 70S reduces waste volume by up to 90%, cuts recycling costs by 70%, and reduces handling and transportation costs by 80%. Briquettes made from natural materials also offer a heat output of 4,000–4,500 kcal/kg, which is 80% higher than that of conventional firewood: a tangible benefit for those who use briquettes as fuel for industrial boilers or fireplaces.
