Quality is more than a word Clean Oven

Ideal for heat treatment requiring air condition of Class 5 cleanliness. The high cleanliness is assured during the temperature heat-up and pull-down. ESPEC's Clean Ovens are used extensively for heat treatment of specimens and drying components in stringent clean air requirements of Class 5 cleanliness. A space-saving upright design, and a large LED display for improved visibility are some of the user-friendly features. Eight models to choose from, including high-performance models which ensure automated operation and dedicated cleanliness even throughout temperature heat-up or cooling...

Utility Class 5 cleanliness level Class 5 cleanliness level is achieved by employing HEPA filters and a back-tofront horizontal laminar circulation system which produces uniform hightemperature airflow. Distance of airflow in the chamber is shortened, resulting in smooth air delivery in between specimens and uniform heat treatment. Additionally, it prevents dust generated from specimens placed upstream from flowing downstream. T he upr ig ht desig n wit h i nst r umentation, heater, and other mechanisms gathered on the upper side saves installation space. Airtight structure ensures zero...
