--- title: MonTech increases RPA capabilities with -40C low temperature testing description: MonTech's unique rubber process analyzer design is now optionally enabled for -40C low temperature testing, allowing greater options for post-cure testing. image: https://resource.montechusa.com/hubfs/MCool-40_Featured_news-image-02-01-1.jpg --- [![MonTech](https://resource.montechusa.com/hs-fs/hubfs/MonTech%20Rubber%20Testing%20Solutions.png?width=500&height=160&name=MonTech%20Rubber%20Testing%20Solutions.png "MonTech")](http://www.montechusa.com) **MonTech's MCool -40°C Greatly Increases Range for Low Temperature RPA Testing** MonTech RPA now reaches -40°C for advanced post-cure testing | The MonTech MCool -40°C is an advanced external liquid cooling system for use in the [D-RPA 3000](https://www.montechusa.com/products/rubber-process-analyzer) and [MDR 30](https://www.montechusa.com/products/moving-die-rheometer/mdr-3000-professional)[00 Professional](https://www.montechusa.com/products/moving-die-rheometer/mdr-3000-professional). It is perfect for testing where extreme low te![Picture1](https://resource.montechusa.com/hs-fs/hubfs/Picture1.png?width=330&name=Picture1.png)mperatures are required, approaching glass transition temperature. The system works in conjunction with the pneumatic cooling system and cools both dies individually, reaching temperatures as low as -40°C (-40°F). This patented cooling system serves as an addition to the instrument’s temperature control, leaving the existing heating system in the dies unchanged and fully operational. All instruments equipped with the MCool -40°C cooling system maintain full functionality of a Moving Die Rheometer or Rubber Process Analyzer   For more information about the Rubber Process Analyzer and the  MCool -40°C Chilled Air Cooling System, [click here](https://www.montechusa.com/products/rubber-process-analyzer). | | --- |       ### Keep up to date on new rubber testing technology! © 2026 MonTech USA.
