Blending stations for polyol and blowing agents

Some PU applications such as spray systems require a ready polyol component which is blended with a blowing agent. For such applications, it is necessary to not just add the blowing agent on the mixing head of the production line, but already in the blender.

H&S provides blending stations for polyol and blowing agents based on the batch process in connection with a buffer tank for storing the blend. The batch technology has a number of advantages

compared to blending systems installed in the production line, as it provides higher flexibility through simultaneous blending and storage. This means that there will always be a certain quantity of blend in case of system failures. Another advantage is that the buffer tank can supply all production lines (not just a single line). When handling blowing agents, particularly flammable blowing agents, it is important to consider the production safety, for example through the explosion-proof design of all electrical parts. H&S has long-standing experience in this area and guarantees a high degree of processing reliability and quality.

Basic and optional devices for H&S blending stations comprise:
