Structure description of small VOC test chamber

Small VOC test chamber from the outside to the inside are: insulation shell, air jacket, work bin, the right side of the equipment bin.

1) insulation shell: metal shell, filled with polyurethane and other insulation materials inside, good insulation can prevent the loss of energy in the test chamber, while isolating the impact of the environment on the work bin, to ensure the stability of the state of the equipment.

2) Air jacket: is the sealed space formed between the inner wall of the insulation layer and the outer wall of the work bin, equivalent to the work bin is wrapped in a layer of air, indirect temperature control by controlling the temperature of the air in the sandwich.

3) Small VOC test chamber of the work bin: made of inert and smooth mirror stainless steel inside, the chamber is well sealed. Carefully selected expanded polytetrafluoroethylene and other clean materials sealed, and maintain a certain micro-positive pressure to prevent the entry of external pollution.

4) Equipment compartment: used to place equipment monitoring devices, temperature control devices, humidity control devices, air supply components, filtration and purification systems, circuit devices, etc.

5) Purification system (multiple purification, efficient control of background concentration)
