Have you been struggling to find a closed loop transfer system for your application because you are handling under pressure? Well look no further than our pressure packs, comprising Schaefer stainless steel containers (available in sizes 20L to 200L) with the innovative Micro Matic MAV pressure valve. The container is fitted with a special pressure neck which securely holds the MAV valve once fitted. The valve is held in such a way to make it impossible to remove if there is any pressure in the container, making it extremely safe. It then delivers the same closed loop transfer safety, sustainability and value benefits as all the Micro Matic products. As well as the safe and secure closed transfer you expect from the Micro Matic extraction systems, the Macro Valve (MAV) is designed with unique keyed flanges to emphasise product integrity and eliminating cross-contamination. Our UN approved pressure packs are the safest, most sustainable and cost-effective way to transfer, store and transport your valuable product under pressure. Contact us to discuss your application and see how our closed transfer systems can solve your chemical handling issues.
