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

• DHS710C (418 Liters): Internal dimensions are 620 × 750 × 900 mm (W×D×H) | External dimensions are 770 × 965 × 1622 mm.

• DHS810C (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: Designed for rigorous high-heat thermal testing, the operating temperature range for both models in the DHS series is from a minimum of Room Temperature + 10°C up to an exceptional maximum of 360°C.

Q4: What is the temperature distribution accuracy of the oven? A: Even with its large vertical footprint and extreme 360°C heat capabilities, the DHS series delivers phenomenal thermal uniformity. It provides a highly rigorous temperature deviation/distribution accuracy of ±4.0°C (at 360°C), alongside an incredibly strict internal temperature fluctuation of just ±0.1°C, guaranteeing that every single layer within the massive chamber receives precise, stable, and identical high-heat treatment.

Q5: How long does it take to reach the maximum temperature? A: The DHS series is engineered with high-efficiency stainless steel heating tubes with fins optimized for rapid thermal recovery at high temperatures. It is capable of safely reaching its extreme maximum operating temperature of 360°C in approximately 80 minutes, which significantly drastically reduces waiting times for industrial-scale batches.

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 against high heat, 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. Because this series operates at 360°C, the insulation utilizes advanced, high-grade aluminosilicate cotton. This specialized 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 DHS series is highly suited for high-volume QA/QC labs, aerospace component manufacturing floors, and advanced materials research facilities conducting temperature characteristic experiments above the standard 260°C threshold. Its key features include a dialog-based key input for simple complex programming (up to 90 segments), a high-visibility LED monitor, and a space-saving vertical footprint. It is ideal for facilities that need industrial-scale baking and curing at 360°C but lack the wide floor space required for traditional horizontal ovens.

Q8: What are the built-in safety features? A: Safety is a paramount priority for Yamato, especially when dealing with massive 558L volumes at 360°C. The DHS 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 key lock function, a power failure compensation function, and a dedicated door switch that instantly 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 DHS 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 (DHS710C) or 37 shelf layers (DHS810C) available at a 30mm spacing, it easily accommodates massive, dense, high-temperature 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), space-saving vertical engineering, and 360°C extreme-temperature capabilities, the DHS 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 specifically choose the DHS series when your laboratory requires three things: the massive volume of an industrial oven (418L to 558L), high-heat capabilities up to 360°C, and a highly constrained floor space. Its vertical design perfectly solves footprint issues without sacrificing Yamato's elite ±0.1°C fluctuation control. Furthermore, it is the ideal choice if your protocols require frequent venting operations, as the series is explicitly engineered to maintain its high-precision thermal control even when 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 and exhaust vents, the DHS 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 DHS 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 for your 360°C protocols, Yamato’s flexible manufacturing approach ensures your Fine Oven perfectly matches your facility's operational requirements.
