DNF Series - Energy Saving & Air Velocity Controllable Oven
DNF301 / DNF411 / DNF611 / DNF811 / DNF911
Laboratory Oven is essential for general heating routines from drying food samples to curing microchips. Lab Oven is one of the fundamental instruments every laboratory should have.
DNF Series is a High-performance, energy-saving, programmable constant temperature, forced convection oven with air velocity control and exhaust dampers. The first 2 in 1 system in the industry!
Two types of circulation, forced and natural convection, in one unit (compatible with model 300/400/600).
Eco-oven with improved air velocity control system and adjustable damper.
Program featured to reduce power consumption significantly.
Superior heat tightness and insulation of chamber.
Excellent dust tightness, dust can hardly enter the chamber.
Air velocity changeable in 10 stages using digital setting of controller.
Standard with 99 step program operation with repeat operation, auto start, auto stop and quick auto stop functions.
Adjustable damper position at chamber front to optimize operation.
Fluorescent display, interactive input method, calibration off-set function.
