+ Main Controller – Pneumatic Tube System

Patchable for connection router to Main Control

The entire system has to be electronically controlled by microprocessors/ computer. The main control unit, which controls the sending process and the compressor unit, supervises all system components. The sending process has to be indicated on display devices. The device also has to provide information to find the cause of a system malfunction. Customer-specific data such as the system’s layout, target numbers, target names, arrival signals, priority and special functions must be selectable on site without change or external reprogramming of memory devices. A integrated uninterrupted power supply must provide the requested system back up time to paste all date before shutting down the system, so after power source is providing energy again an automatic system start will occur and the system status will get back in the operation mode as before. Chosen targets at stored containers must be kept in the memory to proceed them automatically after power failure restart.

All components of the pneumatic tube conveyor are constantly monitored; the operating software has to be based on action reaction control for any device. The status of each device can be checked by the master control unit. A test program must be included to automatically check, move and supervise all of the system’s devices, or specific selected devices, by access via service code from the Station control panel.

During both normal operation and testing, all devices inform the master control unit that the selected functional position has been reached. This ensures that this position truly has been reached. The system is designed in such a way that it does not allow the unobserved pivoting of devices. The system has to come with an efficient fault-clearance program that automatically recognizes operating errors, power failures, time-out errors and other system errors. It also allows the system to continue functioning; there is no need for the operating personnel to intervene.

+ Blower – Pneumatic Tube System

provided with all the mounting accessories and soundproof enclosure

It should have a separate Blowers 2.3 kW, 3 phase 400v/50Hz, 2850 rpm, 220 mbar pressure, 5.1 m3/min for flow rate, with low noise, unidirectional rotation with electronic air switch to switch between compressed air and vacuum.

Each blower should be provided with Frequency Converter for Control of slow speed for sensitive laboratory samples by frequency control of Compressor. The blower should be set go up to 75Hz with the help of Frequency Converter.

+ Station 160mm – Pass Through Type – Pneumatic Tube System

Pass Through Type – Pneumatic Tube System

The Pneumatic Station should be designed as a fully automatic dispatch and receiving unit and used as pass-through station.

  • The Pneumatic Station should be able to send and receive carriers.
  • The conveying direction of the carriers should be both sided (single tube reversing principle).
  • Inserting a carrier into the Pneumatic Station and selecting a target number should be possible independent from system status.
  • The carrier should be loaded on the top side of the Pneumatic Station.
  • The Pneumatic Station should be controlled by the use of the LCD display membrane key pad in non- critical areas and with integrated Touch Panel Display, in the critical areas.
  • The Pneumatic Station should be Steel made, maintenance free gear mechanism, with self-adjusting optical switches, with self-adjusting maintenance free gaskets for noise less operations, contact less censoring of the unit positions. There should not be any air exiting at the pneumatic station. With RFID readers for carrier ID and inventory, which should ensure automatic carrier redistribution to its home address & also non-acceptance of any items than authorized carrier.
  • The Pneumatic Station should have Air cushioned soft landing facility for arriving carrier to protect samples. Provided with carrier rack and receiving basket with cushion.

+ Forwarding Tube – Pneumatic Tube System

Made of PVC of 160 mm OD x 153.6 mm ID

Forwarding tube should include the cost of cable and other tube mounting accessories as are required for networking between Pneumatic Stations. Every Station and Diverter must provide transparent tube.

+ Diverter – Pneumatic Tube System

Smooth Connection between Incoming and Outgoing Tube

The forwarding tube diverter must provide one incoming and three outgoing delivery tubes.

The Diverter must provide a smooth connection between incoming and outgoing tube, to prevent impact on transported items. A maintenance free belt driven rotary oscillating pipe has to be pneumatically sealed to the device housing, to prevent air loss, self-adjusting Teflon gaskets have to provide airtight operation in vacuum and pressure operation.

+ Carriers – Pneumatic Tube System

With suitable holders of vaccutainers and a pair shuttle bung for each container

Carrier for hospital use should be with easy to operate swivel top mechanic, sealed load chamber, to prevent contamination of tubing in the unlikely event of spill of transported goods. This must be realized only by closing the sealed swivel top mechanism.

The “closed” position should be fastened in a lock-in position. The lid should be kept in this position by a spring force and has to be equipped with seals. Furthermore the design of the container must be done in a way that an open carrier can’t be sent. Any carrier has to be equipped with two free programmable data transponder, system according to send receive device used by the manufacturer in the Pneumatic Stations send magazines.

Transponders are used to electronically identify any carrier by a unique address and to offer the user automatic redistribution to home Pneumatic Station and optionally a second address for dedicated locations or special carrier use. The carriers must provide a easily visible wear and tear resistant color coding system, which must be changeable also on site by the user without damage and not requiring special tools.
