High-performance Clean Oven PVHC|232MS¥332MS PV(H)C|212¥232¥332 CAT.No.E87197-U903

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...

3 Utility Fan Heater HEPA filter Door œ Horizontal laminar circulation system 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. The upright design with instrumentation, heater, and other mechanisms gathered on the upper side...

4 Automated operation throughout heat treatment process (High-performance model) An automatic damper is provided as standard for automation in all processes from temperature heat-up to heat treatment and temperature pull-down. To reduce pulldown time, an optional external atmosphere introducing blower forces air into the chamber to supple-ment cooling. High level of cleanliness during temperature heat-up and pull-down (High-performance model) The high-performance model delivers dedicated cleanliness throughout wide temperature ranges by employing HEPA filters which provide stable filtering...
