Energy-Saving Forced Convection Lab Oven (27L-540L) | Revolutionary 2-in-1 System with Programmable Air Control
Yamato's DNF Series delivers the industry's first revolutionary 2-in-1 forced and natural convection system with advanced energy-saving technology and programmable air velocity control. These high-performance ovens feature dual circulation modes (forced and natural convection in select models), 10-stage adjustable air velocity control (600-1500 rpm), superior chamber sealing with excellent dust protection, and comprehensive 99-step programmable operation with repeat functions. Perfect for research laboratories, pharmaceutical facilities, quality control labs, and industrial applications requiring precise temperature control, energy efficiency, and versatile convection options for diverse sample processing needs.
Performance and functions
- 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
Key Benefits
• Revolutionary 2-in-1 design eliminates need for separate ovens • Energy-efficient operation reduces operating costs • Precise air velocity control optimizes sample processing • Superior chamber sealing prevents contamination • Flexible programming accommodates complex protocols • User-friendly controls simplify operation and reduce training time
Safety features
• Advanced chamber sealing technology • Programmable safety functions • Calibration offset for precision maintenance • Interactive control system with error prevention
Includes 1-year manufacturer warranty for reliable performance and peace of mind. Ready to experience the industry's first 2-in-1 convection system with energy-saving technology? Discover the versatility and efficiency of Yamato's DNF Series Forced Convection Ovens today.
