LRE provides high-performance, energy-saving, programmble constant temperature, High Accuracy Mechanical Convection Ovens with air velocity control and exhaust dampers.
Constant temperature ovens achieve an energy-saving rate of 30% to 40% compared to previous models. Air velocity can be changed in 10 stages using the digital setting of the controller. Operability has been enhanced by locating a slider-type open/close adjustment knob on the front side of the main unit.
