The upper and lower compartments are independently controlled for temperature and humidity, ensuring precise conditions are met for different materials within the same cycle.
Enhanced Safety Features
Equipped with an emergency stop device, an alarm indicator light, and a robust control system, the Nitrogen Purge Oven ensures maximum safety during operation. The nitrogen atmosphere prevents flammability issues, making the oven safe for handling various materials in a controlled and secure manner.
Fast Cooling & Temperature Control
The oven is designed with advanced compressor cooling technology combined with circulating water cooling. This allows for rapid temperature reductions from 250°C to RT+10°C within minutes (approximately 5°C per minute), ensuring fast and efficient turnaround times. The cooling system is engineered to withstand high-temperature environments without risk of damage, even under extended operation.
Precise Oxygen Removal Capability
One of the standout features of this oven is its ability to purge oxygen from the chamber to less than 100ppm in under 30 minutes. This capability is particularly important for materials that are highly sensitive to oxidation, such as certain biopharmaceuticals, polymers, and electronics.
Energy Efficiency and Durability
Thanks to a high-efficiency compressor and the forced air cooling method, the oven offers outstanding energy efficiency. With an installed power of 25kW and peak power consumption of 17kW, it operates economically while maintaining consistent performance.
