"Flexibly aligned to your requirements thanks to the modular design"
Design of an AWH product recovery system
The AWH product recovery system consists of:
The pig sending and cleaning station for storage of the pig during production and cleaning processes.The pig sending and cleaning station is integrated in line with the pipeworks and fully designed for CIP and SIP application. It serves to store the pig during the production and cleaning processes. The pig is constantly and entirely streamed by media, guided in its position and secured by a pneumatically operated bolt. By means of the constant streaming around the pig with product or CIP medium, the pig is as clean as the pipeline itself. The pig sending and cleaning station works as transmitting station in a single product recovery system or a transmission and receiving station in a double product recovery system.
Drive media feeding for sending and returning
For safe transportation of sensitive products we offer complete modules for drive media feeding. This compact module provides all connections for driving, release and discharging.
Drive media control for sending and returning
A constant and steady pigging speed is ensured by the well-proven AWH drive control. Independent from the tube length, the flow rate and the pigging speed are controlled mechanically.
Pig receiving and returning station
A pig receiving station consists of a modular flange tube with a retention bolt. A second pig station can be applied as receiving and cleaning station. Hence, the pig is rinsed before it is returned. For pig recognition this is equipped with a magnetic field sensor.
AWH pig with integrated magnet
Tangent pig – one for all purposes
The pig is a one-piece solid body made of food suitable and low wear elastomer. Thanks to its design, it has the optimum, low-wear sealing lip as well as a dimensionally stable guiding bullet.
The AWH tangent pig has proven particularly well in narrow 1.5D bends thanks to its tapered centre. The tangent pig can be applied with T-pieces that are appropriate for pigging and not reduced.
Lip pig – when the going gets tough
The AWH lip pig is a multi-part flow body made of food suitable plastic with a toughened sealing lip made of low-wear elastomer. Its shape of the lip grants long life and operating times, even in abrassive media. The lips can be exchanged separately. The AWH lip pig has proven particularly well in 2.5D bends.

Benefits of the AWH product recovery systems
- developed for fully automatic, validatable operation
- hygienic design, free of dead space, without compromises
- designed for CIP and SIP cleaning
- closed pipe system for safe operation
- the pig remains permanently in the system during cleaning and production. unloading of the pig is not necessary
- pig recognition via the pipe work by magnetic field sensors
- upgradable for existing plants
- design optionally as single or double pigging system, one-way or two-way system
