They Already Trust Us

What our customers say about us?

  • I had some good feedback from the client who uses our MH3 compact thermoelectric counter top cooler: • The filters are very easy to install. • They should help extend the life of the chillers. • They haven't had to replace any chillers that have the filters installed.

    Mike FennellMTL Technologies, Purchasing & Process Improvement
  • I reached out to Permatron about putting branded labels with part numbers on every Thermo King air filter. Some of our customers replaced original equipment air filters with look-alike filters, which had a negative impact on the performance of their equipment. While working on the air filter labels we added a packaging project, requiring a few more labels and packaging material. The project was big, but thanks to an awesome communication flow, the changes were completed fast and implemented seamlessly. Now our customers can easily differentiate between original equipment and non-original equipment air filters.  Because the branded air filters come prepackaged from Permatron, our dock-to-stock time improved by over a week.
