"NPO Center" offers consumers a Airlock feeders for dosing free-flowing powdery granular materials under a manufacturing agreement and is looking for partners to conclude a distribution services agreement.

Airlock feeder is a continuous-action device. It discharges dust without compromising the seal of the apparatus. It ensures a tight seal against the housing walls and maintains the airtightness of the valve.

The world's largest manufacturers of Airlock feeders include Coperion, DMN-Westinghouse, Rotolok, Zeppelin/Reimelt (often branded as Zeppelin or Reimelt), as well as a number of European and local manufacturers (e.g., Jaudt, NIRO, and specialized factories).

Zeppelin/Reimelt is a major German supplier of industrial equipment, often referred to as a manufacturer of rotary valves (Reimelt/Zeppelin).

Rotary valve feeders manufactured by NPO Center are designed for dosing free-flowing powdery granular materials (granule size no larger than 10 mm) with a surface moisture content of no more than 1.5% and a bulk density of no more than 1.8 g/cm³, as well as for unloading accumulated materials from bins, cyclones, silos, etc.

Rotary valve feeders are widely used in aspiration and dust and gas cleaning systems for the uniform delivery of dusty, granular, and small-piece bulk materials to process equipment (crushers, mixers, screens, dryers, granulators, trough washers, etc.).

In pneumatic conveying systems in the food, chemical, polymer, and other industries. Due to their compact size and uniform material discharge, rotary feeders are also used to feed various bulk products into scraper, screw, or belt conveyors, weigh feeders, vibrating screens, and other process equipment.

They are also used in "KI" grinding systems and "KK" classifying systems.

The MS MTT 1600 machine, TRK 80, W100, and 2H637G F1 machines enable the production of assemblies, mechanisms, and medium-sized parts weighing up to 20,000 kg.

The company boasts unique technological equipment, including 1L532 and 1540F1 vertical turning lathes, capable of processing large parts up to 4 m in diameter, up to 2 m in height, and weighing up to 60,000 kg. The company also boasts HAP 4100-160 CNC press brakes, IA 1434, and IB 2424A for bending and rolling metal sheets up to 25 mm thick and 5000 mm wide.

The welding department is equipped with modern, energy-efficient welding equipment operating in pulse mode, saving energy and ensuring high-quality welds. The company operates a mechanized RTK IRB 1600-6/1.45 gas-shielded welding and surfacing system, which reduces the labor intensity of applying wear-resistant coatings by 50% and increases product durability by more than 30%. It also has 30 welding stations certified according to DIN 188000-7 Class E.

The company's automated plasma cutting system for automated shaped and linear cutting of sheet metal products made of corrosion-resistant, ferrous, and non-ferrous metals offers high productivity and guaranteed cut quality (cut thickness: plasma – 0.5-80 mm, oxyacetylene – 20-250 mm). This system reduces material and energy consumption in manufactured products, and significantly reduces labor costs in production through the use of efficient automated metal cutting, eliminating additional machining and manual gas cutting operations.

The KGR-01 waterjet cutting system from NPO Center JSC enables cutting sheet metal and non-conductive materials of varying densities (from granite to foam rubber) with high productivity and guaranteed cut quality.
