The coated stainless steel obviously improves the adsorption capacity of the high-boiling-point materials and polar compounds in test chamber. The chamber absorbs over 80% of tetradecane and 4-phenyl-1-cyclohexene.
This is the pictures in 100* magnification microscope with special-coated and uncoated in VOC Emission Equipment interior stainless steel (which has great mirror-finished surface treatment）

The special invention about how to resolve the VOC recycling in VOC Emission Equipment has successfully applied in China,The United State and Japan.Till now, we are still applying for the patent in Europe.
Unique In United State
Unique In Japan
The VOC test equipmentprovides standard testing environment to determine the VOC emission rate and emission characteristics of interior decoration materials and products. Based on the test report, we can:
Determine the impact of environment variables on the VOC emission rate and emission characteristics.
Classify the level of products and materials according to the emission characteristics.
Develop and adjust indoor air pollution models.
Evaluate the IAQ (Indoor air quality) according to the pollution data and test report.
As being a significant means of VOC emission test, the VOC emission equipmentfinds a wide application in interior decoration, office furniture, engineered wood, carpets, plastics, leather, textile, toys and more.

Operation Testing Methods
The air is first processed by compressor to remove solid particles, formaldehyde and volatile organic compounds, and then enters into the test chamber.
The climate chamber is designed with an air jacket for conditioning the temperature in testing chamber.
By adopting dew point method, the humidity of climate chamber is well regulated and controlled.
In 2013, Simplewell VOC emissions chamber performance upgraded that R&D stainless steel surface easy adsorption VOC problems, VOC cabin prevent adsorption coating treatment. All the 46 sets of VOC chamber sold for free replacement, two VOC emission chambers sold to IKEA also been free upgraded. As the upgraded chamber has great effect on test accuracy,and Simplewell always keeping his integrity management, so IKEA has third purchase. After the VOC emissions chamber upgraded, the IKEA company using our chamber data to compare with Weiss Technik chambers, then they very satisfied with our chamber, since then the IKEA company plan to purchase our VOC emission chamber more for they the products testing;
In 2014, IKEA supplemented 1set of 5M3 VOC emissions chamber and compared the test accuracy with it from 1M3 simplewell chamber,( because they need bigger chambers to meet the product requirements.) And also, the 5M3 testing result is good;
In 2015, IKEA supplemented supplement Simplewell VOC emissions chamber once more.
In 2017~ till now, the IKEA supplemented 7 sets of VOC emission chambers.
Until now, IKEA all the VOC test chambers supplied by Simplewell.
By the way: SGS bought more than 50sets chamber from Simplewell. And 2 years ago, TUV also bought 1set of our VOC emission chamber to test with Weiss Technik, the testing result not bad also. Now they are building a laboratory in Guangzhou plan to buy the VOC emission chambers from us too.
