Pressure vessels for dense phase pneumatic conveying of bulk materials

All TPA vessels are certified to PED standards and, on request, can be certified to ASME or other international standards. They are available in the following versions: • carbon steel; • AISI 304 stainless steel; • AISI 316 stainless steel; • with finishes for food application; The pressure vessels of the TPA line are designed for handling a wide range of materials and blends of different products. They are also recommended for applications over long distances and with large rates; also able to ensure the integrity of the material and limit wear on the pipes. Pressure vessel configuration TPA...

Conveying phases A total cleaning transport system is managed with the complete emptying of the line according to following steps: 1. Fill the conveying vessel. 2. Pressurization with consequent transport e emptying the line. Total cleaning or conventional pneumatic conveying is suitable for handling various materials and is indicated in cases where it is required a complete cleaning of the line after each cycle. It is widely used in multiple applications, for example unloading of weighing systems for the transfer of dosed products or at the mixer discharge where it is necessary to preserve the...

Conveying phases Full pipeline transport is an innovative method in which pressure management is entrusted to a PLC with a specially designed control program to keep speeds constant during conveying. The full pipeline system always uses boosters and keeps the conveying pipeline full following these steps: 1. Fill the pressure vessel. 2. Pressurization and subsequent transport. 3. Depressurization of the empty tank and of the line full of product. The full pipeline conveying is suitable for handling all materials in particular fragile, delicate or abrasive, it is suitable for long distances and...

TPA FULL PIPELINE CONTINUOUS Conveying phases The full pipeline continuous system uses two TPA full pipeline vessels connected in parallel to allow a continuous passage of the material inside the pipeline. The convey phases are the same as those of the full pipeline method with the difference that the pressure vessels are loaded alternately. Full pipeline continuous is suitable for long distances: the use of two vessels with smaller dimensions and overall dimensions than the same cycle carried out with a single tank, allows optimal performance. Conveying times are reduced by alternating the loading...

Pneumatic panels are devices dedicated to the control of pressure and air volumes used in dense phase conveying. In most cases are applied for air regulation, but they can be also used with other inert gases such as nitrogen. For the proper functioning of the systems Air-Tec System, it is necessary to supply air dry or nitrogen at a pressure of 7.5 bar. The pneumatic panels are connected directly to the air storage tank located downstream of the compressor and have the scope of controlling the power supply of both the pressure vessel and the bypass line dedicated to boosters. In the case of handling...

CONTROL PANEL The standard electronic control panels for the TPA line are complete with Siemens S7 1200 series PLC and color touch screen operator panel. Available models: All standard panels have a terminal block with clean contacts for the main I / O signals and, on request, can be programmed for data exchange with Modbus TCP / IP protocol. They are equipped with quick connection systems that allow, thanks to the use of a multipolar wire, can be easily connected to the junction box. In the case of systems installed in Atex zones 22 or 21, the electronic panels must be positioned in a safe area....
