Forced Convection Oven Programmable Energy Saving 300L Overview
Forced Convection Oven Programmable Energy Saving 300L (DNF811) is a programmable mechanical convection oven from Yamato Scientific, offered by LabSupplies.com as an authorized dealer. The 300 L chamber operates from ambient +15 °C up to 260 °C. Energy-saving programming reduces power consumption across long heating and drying cycles.
Chamber interior uses stainless steel plate, while the exterior is chrome-free electrogalvanized carbon steel sheet coated with a chemical-proof baking finish. Tight heat sealing and insulation stabilize internal temperature. Dust tightness limits particle entry, protecting sensitive samples during extended runs.
Power input is 220V, and the unit arrives ready to run on that supply. Footprint measures 32 × 32 × 73 inches at a 330 lb shipping weight. Manufactured in Japan, the oven is backed by Yamato Scientific's ISO 9001:2015 and ISO 14001:2015 certifications.
Key Features
- Energy-saving program: dedicated programming reduces power consumption significantly during operation.
- 99-step programming: supports repeat operation, auto start, auto stop, and quick auto stop functions.
- 10-stage air velocity control: airflow is set digitally through the controller for precise circulation.
- Adjustable front damper: the chamber-front damper position can be tuned to optimize exhaust and uniformity.
- Sealed, insulated chamber: superior heat tightness and dust tightness shield samples from drift and contamination.
- Fluorescent display: interactive input method paired with a calibration off-set function.
How to Choose the Right Convection Oven
Selecting a forced convection oven means matching chamber volume, temperature ceiling, and control sophistication to your protocol and available bench power.
- Capacity: chamber volume determines batch size; the DNF811 offers 300 L for larger or multiple-load workflows.
- Temperature range: confirm the ceiling fits your process — this unit reaches ambient +15 °C to 260 °C.
- Control type: programmable multi-step control suits repeatable, multi-stage cycles, while analog suits simple holds.
- Voltage: verify circuit availability; the DNF811 runs on a 220V supply.
- Footprint and weight: plan placement around the 32 × 32 × 73 inch envelope and 330 lb mass.
- Airflow management: adjustable air velocity and dampers help dial in uniformity for delicate samples.
