Fine Oven (Tall)(DFS710C) - Laboratory & Industrial Drying Oven

Q2: What are the internal size, external size, and capacity in Liters for the DFS models? A: The DFS series offers two massive vertical capacities designed for high-throughput precision processing while taking up minimal floor space:

• DFS710C (418 Liters): Internal dimensions are 620 × 750 × 900 mm (W×D×H) | External dimensions are 770 × 965 × 1622 mm.

• DFS810C (558 Liters): Internal dimensions are 620 × 750 × 1200 mm (W×D×H) | External dimensions are 770 × 965 × 1922 mm.

Q3: What are the maximum and minimum operating temperatures? A: The operating temperature range for both models in the DFS series is from a minimum of Room Temperature + 10°C up to a maximum of 260°C.

Q4: What is the temperature distribution accuracy of the oven? A: Even with its large vertical footprint, the DFS series delivers exceptional thermal uniformity. It provides a highly rigorous temperature distribution accuracy of ±2.0°C (at 260°C), alongside an incredibly strict internal temperature fluctuation of just ±0.5°C and an adjustment accuracy of ±0.2°C, guaranteeing that every layer within the massive chamber receives precise and identical heat treatment.

Q5: How long does it take to reach the maximum temperature? A: The DFS series is engineered with high-efficiency stainless steel heating tubes with fins (4.5kW for the 710C and 6.0kW for the 810C) optimized for rapid thermal recovery. It is capable of safely reaching its maximum operating temperature of 260°C in approximately 50 minutes (for the 418L model) and 60 minutes (for the 558L model).

Q6: What are the internal and exterior materials, and what are the advantages of the insulator? A: The internal chamber is constructed from premium stainless steel plate, offering excellent corrosion resistance, durability, and effortless daily cleaning. The exterior is robustly built from cold-rolled steel plate finished with a chemical-proofing coating, protecting the unit from harsh environments. The insulation utilizes advanced aluminosilicate cotton. This high-grade insulation aggressively prevents heat dissipation, ensures rock-solid internal stability across the massive chamber, lowers energy consumption, and keeps the exterior completely safe for operators to touch.

Q7: What applications is this oven suitable for and what are its key features? A: The DFS series is highly suited for high-volume QA/QC labs, manufacturing floors, and research facilities conducting various temperature characteristic experiments and advanced thermal processing. Its key features include a dialog-based key input that makes complex programming remarkably simple, a high-visibility LED monitor, and a space-saving vertical footprint, making it ideal for facilities that need industrial-scale baking and curing but lack the wide floor space required for horizontal ovens.

Q8: What are the built-in safety features? A: Safety is a paramount priority for Yamato. The DFS series comes fully equipped with a highly responsive self-diagnostic circuit that instantly detects temperature sensor anomalies, heater disconnections, automatic overheating risks, and SSR short-circuits. It also includes an independent overheating prevention device, an overcurrent leakage protection circuit breaker, a control cabinet switch, a key lock function, and a dedicated door switch that halts operation to protect the user if the door is opened.

Q9: What is the shelf load weight capacity? A: Every single model in the DFS series features heavy-duty stainless steel wire mesh shelves structurally engineered to support a substantial load capacity of 30 kg per layer. With up to 27 shelf layers (DFS710C) or 37 shelf layers (DFS810C) available at a 30mm spacing, it easily accommodates massive, dense sample batches.

Q10: Is the price affordable while maintaining Japanese quality? A: Absolutely. Yamato is fiercely dedicated to providing incredibly cost-effective laboratory solutions. Even with its massive capacities (up to 558L) and space-saving vertical engineering, the DFS series is deliberately NOT priced at a premium. This gives your laboratory direct access to an elite standard of Japanese manufacturing without breaking the budget. You receive an instrument built with over 130 years of Yamato’s strict quality control, rigorous testing, and rich engineering heritage, ensuring complete confidence in the long-term reliability and value of your investment.

Q11: When and why should we use this oven? A: You should choose the DFS series when your laboratory requires the massive volume of an industrial oven (418L to 558L) but you are highly constrained by floor space. Its vertical design perfectly solves footprint issues. Furthermore, you should use it when your protocols require frequent venting operations, as the DFS series is specifically engineered to maintain its high-precision thermal control even when the exhaust dampers are in use.

Q12: What standard ports and optional accessories are available? A: Standardly equipped with a 30mm inner diameter cable port located on the right side, the DFS series can be comprehensively customized. Options include extra stainless steel shelves, an automatic vent, an N2 (Nitrogen) introduction device, a micro printer, a data logger, combination warning lights, a temperature output terminal (4~20mA), an external alarm output terminal, a timer output terminal, a touchscreen controller upgrade, and centralized monitoring software.

Q13: Can these ovens be customized to suit specific customer needs? A: Yes. Recognizing that every laboratory has distinct workflows, Yamato can customize the DFS series to a certain level to suit specific customer needs. Whether you require specific port placements for external testing cables, unique data output terminals, specialized centralized monitoring integrations, or automated exhaust venting, Yamato’s flexible manufacturing approach ensures your Fine Oven perfectly matches your facility's operational requirements.
