Bry-Air Centralised Conveying System is designed to handle the most crucial and critical process, Extrusion. The system has been designed keeping in view the continuity required in the extrusion process and thus no place for manual loading of the raw materials. The manual methods include diesel vehicles and other medium of transportation which causes both air and noise pollution. These vehicles are also not safe for the workers who are working on the premises. Manual feeding can also cause spillage of material.
Bry Air Conveying system is a one-stop shop to build accident-free shop floors. It automates resin conveying which helps to reduce downtime and increase uptime, thus reducing cost and improving competitive edge. It eradicates molding defects while simultaneously offering an effective material dust removal system.
Bry-Air’s Centralised Conveying System comes with:
- Receiver
- Regenerative Vacuum Pump Station
- Central Dust Collector
- BrySmart® Controller
Receiver
All the parts in contact with the material are made of SS304. The integrated proximity sensor activates material demand. The special dump valve design mounted on a bearing allows smooth movement of the dump valve’s blanking disc and closing during the conveying process.
The special flapper with long-life silicone seals a mesh filter, load valve and dump valve for a leak proof vacuum. This allows receiver usage at higher temperatures. The special flapper also served the purpose of deflecting incoming material away from the screen.

The Access Door allows servicing and inspection of dump valve assembly without any tools. The receiver comes with a highly effective magnet and a clearly visible tower light for the status of operation and fault. The receiver comes in capacity options of 6/15/30/60 and 75 litres.
Regenerative Vacuum Pump Station
The brushless regenerative pumps are noiseless and low in maintenance. They provide a powerful vacuum to convey free-flowing pellets and regrind. Every unit is fully assembled and permanently lubricated to deliver optimum vacuum and is consolidated on a compact frame.
The optional discharge selection valve allows exhaust air to be recycled back to the closed loop dry air system, or discharged to the atmosphere. Specially designed by-pass valve with silencer, which allows the pump to run on past system demand for prevention of rapid start/ stop cycles and pump overheating.
Safety relief valve and vacuum gauge to provide safety to the pump during certain unavoidable circumstances. State-of-the art microprocessor controlled pump safety system which indicates voltage, current, frequency, load bar graph and a fault display of overload, under voltage, over voltage, phase sequence reversal and failure.
Central Dust Collector
A CRC powder-coated self standing chamber that can be located anywhere between the pump and conveying system. The central dust collector protects the pump and reduces filter maintenance by collecting fines and dust. The separated dust and fines collected are easily cleaned and the sight glass in the chamber provides a view for inspection.
BrySmart® Controller
Touchscreen colour display with a password management system protects the data entry system. Independent controller for each receiver. Clear functional colour display of each receiver and regenerative vacuum pump station.
Possible to program load time, dump time and regrind in % conveying time with respect to source in case of usage of vacuum take-off box (p) and regenerative Vaccum Pump Station Seek Time.
Audio visual warning alarm with a message that conveys shortage, material not conveyed for long, receiver waiting for material and regenerative vacuum power unit tripped. RVPS Isolator switch off and emergency switch off. Alert message for cleaning the filter. The occurrence of setting the alert is programmable.
BCS Conveying System can cater to various requirements such as:
- Conveying and mixing of regrind material with virgin material automatically
- Purging or cleaning the material line at the end of every conveying cycle in case of conveying dried material
- Conveying the material with dry air
Two or more receivers are connected to a central regenerative vacuum pump station through a central dust collector. The PLC control unit performs the function of connecting each receiver to the central regenerative vacuum pump station, in sequence, depending on the demand of material from the respective receivers.
If the signal for material demand exists, it connects that particular receiver to the central regenerative vacuum pump station and the conveying cycle starts. The bypass valve closes and the vacuum valve in the respective receiver opens simultaneously. The differential pressure, which builds up in the vacuum line, continues through the receiver to the extraction point of the material line.
At the material extraction point, a mixture of air and granules is formed and rushes through the material line. The granule is screened off in the receiver by the screen lter. The dust particles contained in the granule, however, pass through the screen lter, and are collected at the central dust collector.
After the material conveying is completed, the PLC control unit checks the next receiver for the signal for the material demand. It starts the conveying cycle if the signal for material demand exists, otherwise, it opens the bypass valve and allows the atmospheric air to enter the regenerative vacuum pump station. The pump is switched off if the by-pass air valve remains open for a preset time. However, the PLC control unit continues to check each receiver for the material requirement signal. It switches on the pump, whenever there is a signal for material requirement from any receiver, and the conveying cycle starts.
