Blue M Batch Oven

Batch Series Mechanical Convection Ovens

Blue M industrial batch ovens provide customers with reliable, superior performance. Available in six (6) standard sizes, these batch ovens are ideal for a variety of testing and industrial applications. The Blue M batch oven utilizes a high volume, horizontal air recirculation system which maximizes temperature uniformity and performance. Built to be compatible with shelves or trucks, these ovens offer the flexibility to meet your loading needs.
