BVV Neocision 3.2CF Vacuum Oven, Built Around Heated Shelves
Heat in this oven comes up through the trays themselves. This BVV oven runs four individually heated shelves, and each one has its own PID controller holding its own setpoint. Under vacuum there is almost no air to carry warmth. Conduction from a heated shelf reaches a slab far faster than radiant heat from the walls. The result is a preheat of about 20 minutes and temperature uniformity within 4% of setpoint. Stability holds at ±1.0°F across a working range from 18°F above room temperature to 212°F. The chamber is 304 stainless steel at roughly 17.7 in on each side, giving 3.2 cu ft of interior volume. Each shelf measures 17 x 17.25 in, about 293 sq in, for roughly 1,173 sq in of heated tray space. Paired with a 12 cfm two-stage pump, it reaches full vacuum in about five minutes and bottoms out below 500 microns. It draws 1050W at 120V, so no 240V run is needed in the lab. The cabinet measures 30 x 27 x 27 in and weighs 260 lb.
Running a Vacuum Oven With Heated Shelves in a Growing Lab
Separate PIDs per shelf are the real working advantage here. A lab can run a gentle low-temperature purge for terpene-rich material on the top tray while a firmer slab finishes on the shelf below. Lay material on parchment directly over the heated plate, pull vacuum first, then bring temperature up once the initial bubbling settles. The glass door and LED strips make it easy to watch each slab pillow and fall without venting the chamber. At around a gram of extract per square inch, a full load lands a little over a kilogram per cycle. Faster heat-up also means more cycles in a shift, which is where this size earns its floor space. The KF25 inlet ships with a 1/4 in JIC adapter, a clamp and HVAC hose, so a standard two-stage pump connects without hunting for fittings. Four shelves is the trade-off. Every slab has to sit on one of those heated plates, so tray count tops out at four. Plan on a dedicated circuit, a level floor and a pallet jack or a few helpers for delivery day.
Key Features
- Four Individually Heated Shelves: Conductive heat goes straight into each tray, which shortens purge cycles compared with heating the walls alone.
- Separate PID Per Shelf: Each shelf holds its own setpoint, so different materials can purge at different temperatures in one run.
- ETL Lab Certification: An ETL mark on the electrical system is the first thing an inspector looks for in a licensed lab.
- Quick Heat-Up: A short preheat lets a lab load, purge and reload more often across a working day.
- 120V Operation: Standard single-phase power keeps installation simple in buildings without spare 240V capacity.
- Window and LED Lighting: A tempered-glass door with LED strips shows every shelf without breaking vacuum.
