Forced-Air Circulation
Forced-air circulation moves hot air through the chamber for sample drying, constant-temperature heating, material pretreatment and quality-control testing.
Touchscreen Control Panel
The microcomputer P.I.D. controller and LED digital display make it easy to set and monitor temperature, supporting laboratory and quality-control applications that require stable temperature control.
Three Chamber Capacities
The DOS30, DOS45 and DOS60 provide 30 L, 72 L and 150 L capacities. Choose according to sample quantity, chamber space and loading requirements.
How to Choose a Hot Air Circulation Oven
For laboratory sample drying, R&D testing or quality inspection, first confirm sample dimensions, batch quantity, target temperature, drying time, temperature-stability requirements, available power and installation space. DOS30 suits smaller capacity needs, DOS45 offers a mid-size option, and DOS60 is intended for larger sample quantities or a larger chamber. Confirm the final choice against the samples and process.
