DZ-1BIV Series Precision Vacuum Drying Oven

The DZ-1BIV series precision vacuum drying ovens (DZ-1BIV, DZ-2BIV, DZ-3BIV, DZ-4BIV) provide efficient vacuum drying for heat-sensitive, easily decomposed, and easily oxidizable substances. Featuring 4-side wall heat conduction with shelf temperature brackets, intelligent PID temperature control from RT+10°C to 250°C, and a digital LCD vacuum gauge.

Temperature Range: RT+10–250 ℃ | Ultimate Vacuum: <133 Pa | 4-Side Wall Heating | Digital LCD Vacuum Gauge | Capacities: 24L to 215L

Key Features

4-Side Wall Heating: Four-wall heat conduction method with temperature sensor brackets accelerates heat transfer to shelves for enhanced drying efficiency.
Superior Chamber Sealing: Integrated inflation port and one-piece molded heat-resistant silicone sealing strip ensure excellent airtight vacuum integrity.
Double-Layer Observation Window: Inner bulletproof explosion-proof tempered glass combined with an outer protective resin shield ensures optimal laboratory operator safety.
Ergonomic Fastening Handle: Heavy-duty clamp handle allows easy, smooth opening and secure airtight door closure.
Intelligent PID Controller: Multi-group data display on a single LCD screen with dual-temperature-section PID regulation and PT100 temperature sensor.
Digital LCD Vacuum Gauge: Accuracy class 0.5 with switchable display units (MPa, kPa, bar, psi, and kgf/cm²).
Comprehensive Control Functions: Timing function (0–9999 min) with timing wait, fixed-temperature operation, auto-stop, sensor deviation correction, temperature overshoot self-tuning, parameter locking, and power-off parameter memory.
Safety Protection: Over-temperature audible and visual alarm system.
