Year of construction: 2015, operating hours: 13,660 h, condition: used, filter area: 18 m², negative pressure: 2,000 Pa, suction capacity: 13,000 m³/h, Oil mist extraction unit for workshop halls – Plug & Play filtration tower designed for extraction of coolant and lubricant emissions in industrial halls. IVAT Ölnebel-T13K filtration and ventilation tower. Ideal for aerosols, oil mist, emulsion mist, and vapor extraction. Industrial hall filtration ventilation – suitable for numerous technological processes in manufacturing plants, particularly in metalworking operations. Very often, extraction systems with coolant recovery installed directly on machines are insufficiently effective or simply not present. Machine retooling, frequent opening of machine enclosures, or lack of enclosure at machining heads causes oil mist to escape from machine areas, exposing workspaces and personnel to harmful mist and vapors. Installing a filtration tower significantly improves air quality at workstations and should be considered an ideal filtration and ventilation supplement for halls where fully isolating oil mist using coolant recovery devices is either impossible or very difficult to achieve. Equipped with automatic air and temperature control for the workspace. An innovative PLC control system monitors data and detects threshold exceedances at the workplace, ceiling heat-up, and automatically regulates temperature and air quality.

Year of construction: 2026, condition: new, functionality: fully functional, Belt press POWERPRESS 300 is designed for pressing fruit, berry and vegetable mash. Fruit mash is supplied on the belt which presses it against shafts. The obtained juice flows into a small collection tank under the press with filtration sieve on top. Then the external pump or juice collection tank with pump transfers the juice from the press to a desired storage tank or straight to ROCKET pasteurizer for further processing. The pressing process is continuous. Capacity: 300 kg/h The most cost-efficient belt press in the market! The most evolutionary feature of our Belt press POWERPRESS 300 is one huge pressing shaft, which lets the machine to maintain the longer pressing time (belt length is 4900 mm) and huge shaft dimensions squeezes the juice efficiently by saving the costs and space. The juice yield of apples using our belt press is ~65-75 %. The yield highly depends on freshness and variety of fruits. There is a filtration sieve integrated into the juice collection tank. Because of that the belt press 300 filtrates the juice even during the pressing stage providing cleaner and purer product. The belt press includes a high-pressure washer, which continuously washes the belt of the machine. Our belt washing system is simple, does not contain any engines or reducers, so it prolongs the use time and saves service costs. Adjustable fruit inlet lever lets fruit mash supply onto the shaft easily. Crushed fruit mash can be supplied from MAXIMILL or straight from a bucket or basket. After work, belt press should be manually washed with a water stream. A full washing process takes around 15 minutes. Washing is simple and all the parts of the belt press are easily removable without any tools. Belt tension is adjustable. The machine is made entirely of stainless steel and has adjustable feet.
