The new Across International AccuTemp-450 vacuum oven now features stainless steel internal tubing that is 2.5X larger than the previous one, for a quicker vacuum purge and release. We have also added an additional door handle to provide a better sealing on the door gasket.
The AccuTemp-450 series digital vacuum oven features a gigantic 450 liters easy-to-clean stainless steel chamber with a large 3/4" tempered glass safety window. With our new internal shelf heating technology, each shelf in these ovens has its own heater, in-shelf temperature sensor and temperature controller, together with great thermal-conductive aluminum and our new low proportional controller technologies, the result is perfect uniformity, accurate temperature, super-fast heating rates, minimum heat loss/exterior temperature and very low power consumption.
Every one of our vacuum ovens goes through a 2-time 24-hour vacuum leak test, and is quality controlled in New Jersey or Nevada before leaving our warehouses.
- Six well thermo-conductive aluminum heated shelves with individual in-shelf temperature sensor, heater and digital temperature controller.
- All stainless steel internal vacuum tubing and compression fittings that holds vacuum 10 times longer and deeper than with rubber tubing. They also provide you the most sanitary working environment, while last for decades without maintenance.
- Oil-filled mechanical vacuum gauge ensures the most accurate and stable measurements.
- Built-in secondary over-temp dial for added protection.
- Adjustable vacuum and vent port with needle valves gives you control over vacuum and vent rates, while also largely enhanced durability.
- 3rd gen low proportional gain temperature controller keeps your oven temperature within +/- 1°C accuracy, in either °F or °C.
- Built-in white LED lights
- Best choice for the curing and converting of oil extracts. With deep vacuum level, they can operate at temperatures which allow the degassing/purging process to occur rapidly, thus increase productivity and allow for the production of superior quality products with minimal processing time.
- Dual layer observation window with 3/4" tempered safety glass.
- Easy-to-clean stainless steel interior for exceptional durability and ease of maintenance.
- A vacuum environment lowers the boiling point (great for processing heat sensitive materials) and reduces drying time for materials like paste or powder which cannot otherwise be easily dried.
- Built-in alarm alerts you when oven has been shut down by safety circuitry due to out of range temperature.
- Built-in station-able swivel casters with locks for ultra-portability.
- All ovens shipped from our Nevada or New Jersey locations for quick delivery, and come with one year warranty and lifetime US-based parts and service support.
- Guaranteed US based phone and email assistance within 30 minutes from our engineers.
