Product Recovery Technology

Lip Pig
Tangent pig

The pig - as clean as the pipeline itself.


Safe discharging of pipelines

Use your product to the last drop and finalize your production the way it begins - with a free pipeline. Gain high-quality product from your pipeline and reduce the cleaning effort for economic production. With the product recovery technology of AWH you can process your valuable product almost entirely. The pig shoves the last drop for processing out of the pipeline. You gain an enormous saving potential for the subsequent cleaning process. You save product and reduce the cleaning effort significantly. Merely a thin residue film is left in the pipeline and the pipe's surface is accessible for short and effective CIP cleaning.

Good reasons for product recovery technology

  • effective usage of the product
  • less cleansing agent
  • less water consumption
  • rapid cleaning results
  • short-term amortization of investments

Product recovery / pipe drainage

The pig can be applied there, where:

  • pumpable products are conveyed
  • frequent or short-term product switch is required
  • product blending of two successive phases should be avoided
  • a product has very poor flowing characteristics
  • the product value does not allow any waste
  • regular cleaning is performed
  • the water contamination should be reduced to a minimum

Process control

AWH's product recovery systems are a well-proven solution for eliminating the product as well as for gentle filling of process pipework systems for sensitive products and products liable to foam.
