Yamato DKV-400 Programmable Forced Air Convection Oven 90L with Color LCD Controller (115V)
Product Description
The Yamato DKV-400 is a programmable forced air convection oven designed for precise thermal control in laboratory and bioprocessing environments. Featuring a 90-liter chamber with dimensions of W450×D450×H450 mm, it supports uniform heating with a forced air circulation system and PID microcomputer temperature control ranging from 0 to 270°C. This oven is equipped with a high-visibility 3.5-inch color LCD controller (VSD-1) allowing easy operation across multiple modes, including fixed setting, quick auto stop, auto start, and programmable operation – making it critical in biopharmaceutical production pipelines and essential for molecular cloning workflows.
Key technical features include:
- Superior temperature accuracy with ±0.6°C gradient at 270°C
- Rapid temperature rise speed of 4.4°C/min reaching max temperature in approx. 55 minutes
- Extensive safety systems: self-diagnostic functions for sensor errors, heater disconnection, SSR short, overheating prevention, fan and relay abnormalities
- Built-in exhaust ports (2 pcs top) and cable hole (right side) to support controlled environment needs
- Durable construction with a stainless steel interior and chrome-free electrogalvanized steel exterior with baked-on coating for corrosion resistance
- Supports heavy loads up to 15 kg per shelf, total chamber load of 30 kg with 11 adjustable shelf steps at 30 mm pitch
- Auxiliary functions such as calibration offset, power failure recovery mode, temperature alarms, fan OFF delay, and external communication terminals (RS-485) for integration with lab automation and monitoring systems
This forced air convection oven is widely used in biotechnology research, clinical diagnostics, biomedical engineering, and synthetic biology research where controlled, repeatable heating conditions are mandatory. The robust safety features and programmable operations make it a reliable choice for laboratories requiring consistent incubation, drying, sterilization, and thermal processing.
