TH-1000 chamber explanation
l TH-1000 capacity is 1000L(Workroom dimension is 1000mm*1000mm*1000mm).
l TH-1000 chamber temperature range(-20 degree to +150 degree) and humidity range (10%~98%).
l Before doing the test, the workroom can be clean by 12m3/h air ventilation. We install activated carbon in the air inlet, so air will be clean before entering the workroom.
l After reaching the set points of temperature and humidity, then put the wood products into the chamber.
l We will provide a air pump for supplying the compressed air. The compressed air also be clean before entering the workroom by activated carbon. The compressed air flow velocity will show on the flowmeter, and you can calculate air volume according to testing time and air velocity.
l You can set air flow rate on the flow meter by valve. Flow meter can display and set air flow velocity.
l The Controller can control and display temperature and humidity. and only show workroom pressure.
l We can install 2 pcs valves to outlet air. The washing bottles will be connected to these valves for absorption formaldehyde gas.
l We will supply the washing bottles.

How to operate this chamber.
First, this chamber don't need any installation, you can directly use it. Before doing the test, you can set 12m3/ h air exchange for clean the workroom.
Second, you need set points of temperature and humidity, and adjust air exchange to 0.5m3/h.
Third, After finished test of all set points, you can open valve, Washing bottles will absorb formaldehyde gas.
Design and Construction
