VOC Environmental Test Chamber

The VOC Environmental Test Chamber LEVOC is a sampling bag type emission chamber for vehicle interior parts such as floor coverings, seats, trim and instrument panels. The part is conditioned at a set temperature and humidity and the air around it is collected in a sampling bag for analysis, following ISO 12219-2:2012(E) for vehicle interior parts and materials. Two series are offered: LEVOC-BIR from RT+20 °C to 90 °C or 120 °C in 24, 32, 36, 48 and 56 m³, and LEVOC-WT from 15 °C to 90 °C or 120 °C in 21, 24 and 32 m³.

How it works

The sample is placed in the chamber at the required temperature and humidity. Background air passes through primary-efficiency and high-efficiency activated carbon filtration: with an inlet VOC concentration below 6.0 ppm the removal rate exceeds 90 percent, and outlet air reaches TVOC of 350 µg/m³ or less, with benzene, acetaldehyde, methylbenzene, ethylbenzene, xylene, formaldehyde and acetone each at 15 µg/m³ or less and styrene at 2 µg/m³ or less. At the set times the operator draws gas from the sampling bag and analyzes it; concentrations taken over time give the emission rate and emission profile of the part.

The chamber is flame retardant, with a stainless steel skin over a polyurethane interlayer. The sealing door measures (1 m + 1 m) × 1.9 m with a T5 tempered glass observation window, both edged in stainless steel; a double-door version joins the panels with stainless steel plates and PTFE tape. Blinds provide ventilation.

What is included

• Chamber LEVOC-BIR or LEVOC-WT in the selected internal volume
• Sealing door with observation window, single or double door type
• Activated carbon filtration, primary efficiency and high efficiency
• Inlet and outlet pipes (wall drilling by the customer)

Specify for your project

• Series and internal volume, 21 to 56 m³, for the parts to be tested
• Upper temperature limit, 90 °C or 120 °C, and humidity control required
• Door type: single sealing door or double door
• Site: 220 V 15 A supply, wall penetrations for pipes, location away from high VOC sources
• Analysis method used downstream of the sampling bag

Application of VOC Environmental Test Chamber LEVOC

The LEVOC test chamber with sampling bag is applicable for car floor,seats,interior decoration and instrument board,etc.

Technical Parameters of VOC Environmental Test Chamber LEVOC

Structure Features of VOC Environmental Test Chamber LEVOC

1. The test chamber has flame retardant capacity,thanks to the stainless steel cover and PU interlayer.
2. Two types of doors are provided.The sealing door has a size of (1m+1m) ×1.9m and the observation window utilizes T5 tempered glass.Both door and window are edged with stainless steel.For the double door type,the chamber joint uses stainless steel plates Teflon tapes.
3. Blinds are used for ventilation.
4. The filtration system utilizes activated carbon primary-efficiency and high-efficiency activated carbon.

Technical Parameters of VOC Environmental Test Chamber LEVOC

When the concentration of VOC is less than 6.0PPM,the sampling bag type VOC test chamber ensures a removal rate of more than 90%.And the concentration can be lowered to 0.35mg/m³(350ug/m³) and the concentration of other volatile organic compounds is as follows:

The testing by this LEVOC test chamber is compliant with ISO 12219-2:2012(E) standard for the determination of the emission of volatile organic compounds from vehicle interior parts and materials.

Installation Environment Requirements

1. The equipment cannot be installed near a place with high-concentration LEVOC emission.
2. 220V 15A power supply is required.
3. The inlet and outlet pipes are offered by our company.Customers need to help us with wall drilling and other auxiliary work.
4. When installing,the fire alarm and sprinkler should be closed temporarily in case for mal-operation.
5. If needed,we can sand the floor below the machine.
