Blending station for polyol and Blowing agents:

blending-station-polyol-a-blowing-agentsSome PU application like for example spray systems require ready-made polyol component mixed with blowing agent. For such applications it is necessary to bring the blowing agent to the polyol mixture not on the mixing head of production line but in the blender already.
H&S offers blending stations for polyol and blowing agent based on batch process in conjunction with a buffer tank for storing the blend. Batch technology gives a number of advantages over the online mixing units, it provides more flexibility as it enables mixing and storing at the same time. That means in case of some possible breaks a stock of blend will be always available. Another advantage is that from the buffer tank it will be possible to supply all production lines and not only one. While handling blowing agents especially flammable ones it is important to consider production safety like for example ex-proof design of all electrical parts. H&S has a long experience and guarantees high level of processing safety and quality.
