HAMMANN was part of the ZIM-joint project WÄRMER from 2014 till 2016. In that cooperation, we developed an innovative service package for the effective cleaning of heat exchangers without chemical cleaning agents.

This service package contained preparation, cleaning and monitoring based on our COMPREX®-technique. At the same time, the process enhanced for the effective cleaning of heat exchangers.

Cleaning of heat exchangers with COMPREX® results in remarkably short times of shutdown and lower effort. Due the avoidance of chemical cleaning agents, the cost and effort for discharge can be decreased significantly. The monitoring while cleaning is a highly innovative feature but also a requirement for the automatic control of the cleaning process.

The IWW water centre (Mülheim, Germany) develops model deposits, characterizes and quantifies deposits. Furthermore, the success of cleaning deposits such as biofilms. The IWW is also involved in case studies and experiments in the pilot plants to evaluate the performance of the COMPREX®-process. The Institute for Chemical and Thermal Process Engineering (TU Braunschweig) evaluates possible applications and does the thermal characterization of the cleaning process.
