Customizable Eco-Friendly Environmental Test Chamber for Voc Sampling2.

Product Description

Product Description

Bag method VOC emission chamber

Muni offers 24m³ and 42m³ bag-based VOC release chambers, with customizable options.

Working Principle

In the bag method sampling chamber, materials or samples are placed inside. Temperature, humidity, and air change rate are adjusted as needed. Samples are taken for analysis, identifying pollutants and tracking concentration changes over time. Based on these, release rates and characteristics are determined.

Chamber Body Structure
Internal Material	The interior uses SUS mirror-finish stainless steel material. The exterior uses white color-coated steel plate, with intermediate PU insulation material (thickness 100mm) + fireproof treatment, and the edges are surrounded by dedicated aluminum profiles.
External Material	Dedicated warehouse board splicing structure (color-coated steel plate)
Internal Support Frame of Chamber	4.1 Equipped with adjustable brackets for easy sample placement. The brackets are made of stainless steel material and do not emit VOCs.
Chamber Door	Double doors, 2x1.9m (width x height). In the locked state, they can be opened internally. Each door is equipped with an observation window, measuring 600mm x 400mm, with transparent tempered glass used for the observation window.
Bottom	Designed to facilitate entry and exit of small vehicles.

Interior uses stainless steel mirror surface 304#, easy to clean and pollution-free.

Chamber connections use stainless steel mirror surface 304# with PTET, bolted.

Door sealing uses fluorine materials and stainless steel, preventing contamination.

Glass viewing windows sealed with PTET.

Outdoor lamp through glass; indoor lighting: 500lux at 1000mm. Divided control, switches at entrances/exits, control room. Emergency lights last >1 hour.

Floor: 2mm mirror stainless steel 304#, PTET sealing. Optional thermal panel.

Circulation fan blades use 316 stainless steel, high-temp resistant, anti-corrosion.

Inside chamber: no volatile materials, just glass and PTET stainless steel.

New air system with frequency conversion fan, mirror surface stainless steel duct. Air change rate ~10 times/hour, adjustable.

New air system ensures clean air, meeting cleanliness standards through replacement.

Positive pressure system holds 1000Pa: 42m³X10³/min. Maintains slight 10Pa pressure.

During background inspections, customers perform sampling tests; we adjust VOC concentration.

Sampling ports made on-site post-installation per customer needs.

Control System	Uses a TFT color 10-inch LCD human-machine interface touchscreen automatic controller, directly sets temperature, air change frequency and other parameters, and automatically operates.
Operation Mode	Program mode, set value mode
Setting Method	Chinese menu, touchscreen input, and remote centralized control.
Display Resolution	Temperature: 0.1°C; Time: 1 minute; Pressure: 1 Pa
Curve Recording Function	The device is equipped with battery-protected RAM that can save the set values and sampling values of the equipment as well as the sampling time. *The maximum recording time is 60 days.
File Printing Function	Through dedicated PC software, it can directly display and print test data/curves (the printed data table has an unmodifiable mark); or convert the recorded data into an ACCESS database file readable by MS OFFICE.
	When the circulating fan blower fails, stop the heater and sample power supply and alarm.
	Independent overheating protection mechanism: when the heating system exceeds the set temperature, the heater stops heating, but the system still runs normally. After returning to normal, the heater continues to run normally;
	Equipped with alarm lights for motor overload, indoor overheating, etc., sound and light alarm protection
Air Conditioning System	Temperature control: The air heater uses 24KW electric heating. Temperature control uses high-precision PT1000 temperature sensor
	Circulating airflow: Designed based on aerodynamics for circulating air ducts
	Internal circulation fan uses silent fans (68 decibels), meeting uniformity requirements for circulating airflow. The circulating air duct is equipped with exhaust devices.
Base Concentration	Clean air treatment system outlet air: TVOC < 200ug/m³; single VOC < 20ug/m³.
Air Change Rate	Adjustable, not less than 10 times/hour
Noise	Measurement value at a distance of 5m from the equipment is less than 70 dB (excluding air compressor)
