Dynamic Air offers 16 different pneumatic conveying concepts:
LDP 10,000 Full Line Pressure Concept™
Continuous Medium Phase Pressure System
The LDP 10,000 Pressure Concept Conveying System is a medium phase, low pressure, low to medium velocity, continuous conveying system for longer distances. It is generally used to convey medium to high density, semi-abrasive, fluidizable materials which can be somewhat difficult to convey. Examples include coffee beans, powdered chocolate, ground limestone, calcium carbonate, alumina, iron oxide, cement and silica flour.
Typical conveying velocities are generally about 1500 feet per minute (7.5 m/sec) and the conveying pressure is up to 15 PSIG (1 barg).
This concept uses a pressure vessel to feed the material into the conveying line and DC-5 Air Saver technology to minimize and optimize the low pressure supply air which is supplied by a low pressure positive displacement blower.

HDP 4000 Full Line Concept™ - Dense Phase Pressure System
The HDP 4000 Full Line Concept Pressure Conveying System is a dense phase, medium to high pressure, low to medium velocity, batch type conveying system. It is generally used for conveying medium to high density, heat sensitive, semi-abrasive and/or very abrasive, cohesive, and/or very fragile materials in almost any particle size range over long distances. Examples include silica sand, glass batch, granulated sugar, powdered sugar, finished breakfast cereal, coffee beans, plastic pellets, bentonite, cement, starch, silica flour, ball clay, kaolin clay, zinc oxide and alumina.
Typical conveying velocities are generally in the range of 100 to 1000 feet per minute (0.5 m to 5 m/sec) and the conveying pressure up to 100 PSIG (7 barg).
This concept uses a single, non-fluidizing type pressure vessel to feed material into the conveying line at maximum density. DC-5 Air Saver technology is used to minimize and optimize the high pressure air which is supplied by a high pressure - up to 100 PSIG (7 barg) - air compressor. This concept does not need diverter valves but uses valve receivers which provide a distinct maintenance advantage as they are located on the silo tops for easy access.

The proven conveyor to transport dry, granular and free-flowing bulk material in a current of air under pressure.
KLEIN pressure vessel conveyors type T are used in the following industries:
foundry and steel, chemical and pharmaceutical, glass and ceramics, food and animal feeds, quarry and earth shifting, and sand feeding systems for rail vehicles.
Flow takes place in cycles, alternating between filling, and conveying from, the pressure vessel. Compressed air pushes the granular or bulk material out of the pressure vessel through a conveying pipe. In this process the end of the pipe immediately after the pressure vessel, is filled over the full cross section. Depending on the adjustment of the system and the properties of the conveyed product, a series of plugs is formed, and the distance between these will increase as the conveying distance increases. There is, however, no dispersal effect.
During each conveying cycle, solely the content of the pressure vessel is released into the conveying pipeline. The conveying pipe remains filled so that each conveying cycle is started against a full pipe. Thus, wear and material abrasion are considerably reduced.
Conveying plants equipped with a KLEIN pressure vessel conveyor type T make up a closed system and operate almost free of abrasion, wear and similar undesirable interaction. They are compact, easy to maintain, and generate little noise.

Vakuum-Conveyors with Inerting-Function:
Volkmann Inert-Conveyors INEX
Our Vacuum Conveyors INEX with Inerting function are based on the Vacuum Conveyor families VR and PPC. They transfer materials under inert conditions into all sorts of process machinery. Optional the whole conveying process itself can be done under Nitrogen or other inert gases. INEX Vacuum Conveyors are the reliable solution for transferring easily inflammable bulk materials, for the filling of reactors under atmospheric conditions, which have burnable liquids of gases inside.
In the first step, the product is conveyed under air or inert gas into the separator container of the vacuum conveyor. After filling of the separating container the conveyors product inlet is closed and the product inside the conveyor is set under vacuum (-50 to -90 kPa, depending on the application). Subsequently, the pressure inside the separator is balanced with inert gas. This inerting can be done several (usually 3) times, to ensure a high level of Oxygen reduction.
Then the material is released from the conveyor through its bottom discharge valve. Since ignitable gases may move upwards into the conveyor during its discharge through the discharge valve, a new inerting cycle is run to bring the interior of the conveyor back into inert conditions before the next material suction cycle.
INEX Vacuum Conveyors are highly interesting for the filling of reactors, if the solids can be brought into the vessels under atmospheric pressure conditions. If a positive pressure in the unit to be fed occurs during the following process, the INEX conveyor is disconnected by a pressure resistant valve (if necessary with safety monitoring and pressure relief). INEX vacuum conveyors have all the advantages of VR- and PPC Conveyors. They are lightweight, easy to assemble and disassemble, have superior material qualities and can be used in FDA applications. They are much easier in operation than pressure-proof vacuum conveyors and come with really working filter units with big filtration area.
A unit, which your production workers won't give away any more after installation.
