Product Description
The Yamato DKV Series is the programmable tier of forced convection laboratory ovens: four chamber sizes from 90 to 545 litres, all driven by the VSD-1 controller with a 3.5-inch colour LCD. Where a basic oven holds one setpoint, the DKV runs a multi-step program — ramp, soak, ramp again — and repeats it identically every time.
This is the oven specified when the thermal profile is part of the method rather than an afterthought: resin curing schedules, controlled dry-down, stability and accelerated ageing work, and any protocol an auditor will ask you to reproduce.
Key Features
- VSD-1 programmable controller with 3.5-inch colour LCD and program preview
- Operating range to 270 °C (220 °C on the DKV-910), with temperature fluctuation as tight as ±0.5 °C
- Clock timer that schedules a start up to 31 days ahead
- Six operation modes including program operation and timed program auto-start
- Operation trend display and calibration offset
- RS-485 communication, 4–20 mA temperature output, time-up, error and recorder terminals for logging and integration
- Temperature upper and lower limit alarms, fan-off delay, power failure return mode and security management
