Here we have an example of our PerMix Sanitary Paddle Mixer with an electropolished finished on the interior & exterior. Part of creating an electropolished finish is also the need to have a Passivation Certificate shipped with the mixer. This experience is why PerMix leads the industry in mixing technology, creating a sustainable partnership between the customer and our team. And the PerMix Best In Performance, Best In Quality, Best In Price, & Best In Warranty philosophy is why we are winning the hearts of our customers and becoming the most disruptive brand in the industry, setting the standards others follow.
