Larger Size 500L/1000L High-Temp Vacuum Drying Oven

LAB1ST Largee Size VO Series Vacuum Drying Oven covers the full range from pilot-scale to production-scale vacuum processing in a single, configurable platform. Choose 500 L or 1000 L of chamber volume, then choose your heating architecture — uniform chamber heating for gentle, even drying, or independent shelf heating for faster ramp-up, higher temperatures up to 250 °C, and per-shelf temperature control. Every configuration shares the same core build: a stainless steel 304 working chamber, a calibrated 4th-generation LCD temperature controller with a 1–9999 minute countdown timer, an oil-filled mechanical vacuum gauge, a dedicated inert gas inlet valve, a standard KF vacuum port, an independent over-temperature protector, and a thickened electrostatic powder-coated cold-rolled steel cabinet. Key Features: Two chamber volumes, one platform — 500 L and 1000 L, fully customizable from 23 L to 1000 L Two heating architectures — chamber heating (up to 200 °C) or independent shelf heating (up to 250 °C) Up to 250 °C working temperature with ±1 °C stability and 0.1 °C control resolution on 1000 L models Vacuum down to <50 Pa via standard KF25 or KF40 vacuum ports Stainless Steel 304 interior — durable, easy to clean, non-contaminating Independent shelf temperature control — run a different temperature on each shelf in a single cycle Heating time under 30 minutes on the 1000 L shelf-heated models Calibrated 4th-generation controller with programmable 1–9999 minute countdown timer Dedicated inert gas inlet valve — N₂ or other inert gases; quick-plug Φ6 mm push-in fitting on 1000 L models Vertical chamber design for ergonomic front loading and a smaller footprint Ceramic fiber cotton insulation on 1000 L models — lower heat loss, lower surface temperature Comprehensive safety suite — leakage protection, over-temperature protection, overload protection, plus an independent over-temperature protector on 500 L models Thickened electrostatic powder-coated cabinet — strong corrosion resistance for production environments Wide option range — 7″ PLC touchscreen, digital vacuum gauge, vacuum controller, cold trap, chiller, oil-free screw pump, high-vacuum (<1 Pa), 300/400/500 °C high-temp builds Specifications: Parameter VO-18E VO-18P Capacity 500 L / 17.66 cu ft 500 L / 17.66 cu ft Temperature Range RT+15~200 °C RT+15~250 °C Heating Method Chamber heating (external chamber-wall heating) Independent shelf heating Shelf Quantity (Std / Max) 5 / 10 7 Shelf Size 780 × 625 mm 610 × 740 mm Interior Dimensions (W×D×H) 630 × 810 × 845 mm 630 × 810 × 845 mm Exterior Dimensions (W×D×H) 950 × 950 × 1115 mm 950 × 950 × 1115 mm Vacuum Port KF25 KF25 Vacuum Level <50 Pa <50 Pa Recommended Pump 8 L/s 8 L/s Gross Weight 600 kg 600 kg Power Input 3500 W 3900 W Power Supply AC220V 50Hz AC380V 50Hz / AC220V 60Hz Interior Material Stainless Steel 304 Stainless Steel 304 Exterior Cold-rolled steel plate, electrostatic powder coating Cold-rolled steel plate, electrostatic powder coating Chamber Design Rectangular, vertical Rectangular, vertical Interior Light LED LED Vacuum Gauge Oil-filled mechanical Oil-filled mechanical Inert Gas Inlet Dedicated valve Dedicated valve Safety Independent over-temperature protector with indicator Independent over-temperature protector with indicator Timer 1–9999 minutes (programmable) 1–9999 minutes (programmable) Parameter VO-1000P VO-1000P-C Capacity 1000 L / 35.31 cu ft 1000 L / 35.31 cu ft Temperature Range RT+15~250 °C RT+15~250 °C Temperature Control Resolution 0.1 °C 0.1 °C Temperature Stability ±1 °C ±1 °C Heating Time <30 min <30 min Heating Method Independent shelf heating Independent shelf heating Shelf Quantity 6 7 Shelf Size 980 × 880 mm 980 × 880 mm Total Heated Shelf Area ≈5.17 m² (≈55.7 sq ft) ≈6.04 m² (≈65.0 sq ft) Interior Dimensions (W×D×H) 1000 × 950 × 1000 mm 1000 × 950 × 1000 mm Exterior Dimensions (W×D×H) 1500 × 1200 × 1700 mm 1500 × 1200 × 1700 mm Vacuum Port KF40 KF40 Vacuum Level <50 Pa <50 Pa Recommended Pump 14 L/s 14 L/s N₂ Inlet Port Quick plug connector, Φ6 mm straight push-in fitting Quick plug connector, Φ6 mm straight push-in fitting Gross Weight 1000 kg 1000 kg Power Input 6200 W 6200 W Power Supply AC380V 50Hz / AC220V 60Hz, 3 Phase AC380V 50Hz / AC220V 60Hz, 3 Phase Insulation Layer Ceramic fiber cotton Ceramic fiber cotton Interior Material Stainless Steel 304 Stainless Steel 304 Exterior Thickened cold-rolled steel plate, electrostatic powder coating Thickened cold-rolled steel plate, electrostatic powder coating Chamber Design Rectangular, vertical Rectangular, vertical Vacuum Gauge Oil-filled mechanical Oil-filled mechanical Safety Leakage protection, over-temperature protection, overload protection Leakage protection, over-temperature protection, overload protection Controller 4th-gen LCD standard; 7" PLC touchscreen optional 4th-gen LCD standard; 7" PLC touchscreen optional
