Skorpion 650 EB is a stationary drum chipper designed for chipping flat edgings, round timber, various types of furniture and sawmill waste of a width to 650 mm. The drive section of Skorpion 500 EB chipper is a 90 or 110 kW slow-running electric motor. In contrast to high-speed motors, this motor is features more stable operation and higher torque. A slow-speed motor with the same power achieves greater energy transmission, and by increasing the diameter of the pulley on this motor, the service life of the V-belts is extended. The cutting system of the chipper includes a drum with 2, 3 or optionally 4 cutting knives and 1 counter-knife. Screen used in the construction of this chipper ensures high regularity in size of the product. The required size of chips can be obtained by adequate configuration of suitable number of knives on the drum and the diameter of holes in the screen.

CSB series drum driers manufactured by our company with a capacity of 2 to 15 t/h are intended for drying chipped biomass, including sawdust, microchips, straw, etc. All models of CSB series drum dryers are adapted to work with heat generators for both wet (humidity up to 55%) and dry biomass (humidity up to 20%). Our dryers are designed with a view to maximally increase the level of safety during their operation which is guaranteed by the significant reduction in the temperature of the drying agent, the application of a flap automatically cutting off the flow of the drying agent to the drum of the dryer and the implementation of a modern fire protection system and an exhaust gas purification system in all dryer models.CSB series drum dryers feature a solid construction and aesthetic design. They work stably and efficiently.

Our company offers BT series belt dryers from GermanSTELA Laxhuber GmbHand ATSS series from Polish company AMS elektronik. They are equipped with our proprietary control system and are designed for drying shredded biomass, such as sawdust, microchips, straw, etc. They feature a lower temperature of the drying factor than in drum dryers. The drying factor can be hot water with a temperature of up to 90°C, a glycol-based heating fluid with a maximum temperature of 120°C or, just like in drum dryers, hot air, but not exceeding 100°C.The upper temperature limit of the drying agent is imposed by the physical and chemical properties of the belt material. Belt dryers in the BT and ATSS series can achieve a capacity of 2 to 15 t/h.

The range of our products includes control cabinets enclosures for indoor and outdoor applications only from the most reputable European brands. Our cabinets are equipped with 3 mm thick mounting plates which allows us to mount even the most demanding equipment without losing the flexibility of the plate. The skeleton construction of enclosures based on closed profiles allows their unlimited expansion and joining switchboards in series. The devives used by us in every switchgear is feature durability and compactness. These are exclusively products of market-leading manufacturers such as SIEMENS, SCHNEDIER, Rittal or EATON. Besides, depending on their location, we install heating or cooling systems in each cabinet. We offer our clients a comprehensive service, starting from the design and construction of a control cabinet through its installation and commissioning.

Preparation system for granulation (PSfG) is our proprietary solution whose task is to stabilise and maintain the moisture content of the material fed to the granulation section at a level of ± 0.5% and to dose an appropriate amount of binder (e.g. corn meal), which significantly impacts on improving the physical and chemical properties of the final product. Stable moisture content and the addition of the proper amount of binder have a key impact on obtaining and maintaining high quality parameters of the pellets produced, such as: calorific value, hardness, strength, amount of ash after burning and dust content in the pellets. Proper moistening and maintaining the humidity of the sawdust at the required level greatly facilitates the compacting and binding of the material particles into granules, and thus enables to achieve a uniformly high quality of granules.

Our original control systems for technological processes are based on PLC controllers. In the installations designed and manufactured by us, we mainly use subassemblies from market-leading brands such as SIEMENS, Allen-Bradley or EATON. We can implement any controller offered by the manufacturers mentioned above to our systems. Our goal is to constantly develop, expand our knowledge and improve our workshop. In our projects, we strive to communicate the largest possible number of equipment used with one compatible communication protocol, thus avoiding additional electrical connections and gaining an easy possibility to diagnose problems caused in case of a potential failure. In our applications, we use SCADA and HMI systems. Each of them features a huge range of possibilities and allows to adapt particular requirements to specific solutions individually designed for a given client.

We design, manufacture, build, train and service The pellet production lines designed and installed by our company offer capacities ranging from 2 t/h to 20 t/h. The capacity achieved naturally depends on the number and power of the machines and equipment comprising the production line. Pellet production lines – the offer: •design (technical conceptual design, formal arrangements, technical documentation, manuals, cost calculation), •supply (machines, devices, measuring and control apparatus, control cabinets, and all installation materials), •installation (machines, devices, control cabinets, measurement, control and feed wiring, post-installation testing, acceptance measurements), •software (controllers, operator panels, visualisation and control systems), •commissioning (machines, devices, control cabinets, control and power installations), •training process operators, programmers and IT technicians and technical human resources, •service within the warranty period and beyon
