Units of this type are widely used in meat processing plants, butcher shops, slaughterhouses, cold storage warehouses, breweries, and the dairy industry to supply refrigeration and freezer rooms, quick-cooling tunnels, or technological lines for cooling liquids. The heart of the system is the legendary, 4-cylinder semi-hermetic Bitzer compressor, characterized by its exceptional performance, high energy efficiency (even under partial load), and unparalleled mechanical durability. The compressor is integrated with a horizontal Bitzer F 400 H liquid tank with a capacity of 39 liters (pressure resistance up to 28 bar), which acts as a buffer for the liquid refrigerant, stabilizing the operation of the entire system under varying ambient temperatures and evaporator thermal loads. The offered set also includes additional extensive supporting infrastructure: a vertical medium buffer tank (dimensions: Ø 1100 x 2600 mm), a high-performance Grundfos circulation pump, and a control switchboard with complete electrical equipment and protection devices (pressure switches, contactors). Thanks to this, the unit can be used directly as a complete, self-contained refrigeration machine room.

Condition: good (used), Kistler NC joining module with dual-station/spindle unit Kistler NCFH 60 servo press with feed slide & spindle station The Kistler NCFH 60 NC joining module is integrated into an industrial dual-station/spindle unit designed for automated series production (e.g., friction welding or precision pressing). The system is characterized by exceptional precision, integrated force-displacement monitoring (piezoelectric sensor technology), and an extremely robust design capable of withstanding continuous industrial loads. Precise press-fitting and joining: Ideal for high-precision assembly processes in the automotive industry, electronics manufacturing, or general mechanical engineering. Integrated quality assurance (force-displacement monitoring): Using built-in piezoelectric sensors, the module measures the exact tensile and compressive forces acting during the pressing process in relation to position. Flexible process control: Enables advanced functions such as "joining to block," position-controlled pressing, or force-controlled joining (when combined with a suitable controller, e.g., Kistler maXYmos). Automated workpiece holding: The coupled spindle station features an automated clamping function (pneumatically or hydraulically actuated via integrated cylinders), making it perfect for automated series production and assembly lines. Sturdy machine bed: The entire mechanical assembly is mounted on a heavy-duty welded steel frame to withstand the immense forces (up to 6 tons per side) generated during operation.
