Features

High temperature resistant high efficiency filter, keeping the internal Cleanliness level of the high temperature chamber (in a class 10000 cleanroom) at grade 100 through vertical circulation.
Circular arc in the chamber designed to prevent accumulation and settlement without dead angle.
The inner chamber adopts jacket design, ensuring the cleanliness of the inner chamber during cooling.
Using air to achieve rapid cooling, saving a lot of nitrogen compared with traditional models.
Special temperature controller.
Small temperature fluctuation and deviation.
Manually adjusted nitrogen flow and display of the float flowmeter scale
The solenoid valve controls the nitrogen flow to decrease when the temperature is stable (after oxygen content is reached).

Optional Function

Automatic regulation of inert gas flow by electronic flowmeter software
Online oxygen concentration analyzer
