VOC Emission Test Chambers

Copertina 636x534


Chambers for volatile organic compounds (VOC) and formaldehyde emission tests according to international standards as ISO 16000-9, UNI CEN/TS 16516, GEV testing methods, ASTM D5116, ASTM D6007, UNI EN 717-1, GREENGUARD UL2818, UL2819, UL2820, UL2821, UL2822, UL2823 and many other technical standards.

These systems are fully automatic: once either the required reference standard (e.g. ISO 16000-9, CEN/TS 16516 etc.) is selected for the test chamber the system loads the paramenters and times of the selected standard and:
. controls environmental conditions (Temperature, Relative Humidity, Air changes per hour and air velocity) inside the test chamber
. alerts the operator via mail, with the set advance, when the air sampling ir required
. ends the test and generates the test report, sending it by e-mail to the preset addresses.
. sends alarms, alerts and memoranda to the operator via mail

If desired the test parameters can be manually set.

A remarkable feature of the 250L/225L test chambers is that they are suitable both for VOC and formaldehyde emission tests according to the reference standards listed above and for formaldehyde tests according to UNI 717-1.

Standard available configurations:

. 8 test chambers, 110 L each, full-optional version

. 6 test chambers, 250 L each, full optional version
. 4 test chambers, 250 L each, full optional version
. 2 test chambers, 250 L each, full optional version

. 1 test chamber, 1000 L, full-optional version

. 1 test chamber, 6000 L, full-optional version

. 8 test chambers, 110 L each, basic configuration stand-alone unit, fully and independently operating VOC emission tests, w/o measures and controls inside the test chambers, ready to be implemented to the full-optional version (our standard design)

Note: all the 250 L test chambers can be supplied c/w a volume compensator to reduce volume to 225 L and c/w a second air velocity meter. In this way the 250L/225L can be used both for formaldehyde emission test acc. to UNI 717-1 and to VOC/formaldehyde emission test according to all the other standards.

These are our standard systems and the more frequently required by Customers; we can design and manufacture other configurations on request.

VOC emission test chamber Systems maintenance requirements and consumable replacement frequency depend upon use conditions. Filters life expectancy is fixed by the supplier to 2 years. 
CLR Srl offers two different service agreements that can be subscribed by the Customer with costs that remain fixed for 2 years including the cost of consumable parts as listed.
During scheduled maintence visits CLR engineer will operate preventive maintenance and diagnostics of all system components; every 24 months he will replace the filters at the inlet of the system.
In case no service agreement is undersigned, CLR Engineers are always available for technical assistance on site upon Customer request. The cost of this technical assistence is listed in our document “CLR - Service Conditions” and the replaced parts will be separately invoiced together with the service
The most important advantage of a scheduled maintenance agreement is to avoid any unexpected dowtime that, if occurring during a long term test, would lead to a loss of days of work.

VOC and Formaldehyde emission test chambers

Foto 8x110 2018General System description in the standard configurations

Test chambers walls: stainless steel, AISI 304, mirror finishing or supermirror finishing
Test chambers ports: stainless steel, AISI 304, mirror finishing, glass inspection windows
Seals on the test chambers ports: Sponge Viton, other seals: Viton, PTFE

Temperature conditions inside each test chamber
23°C±1°C (test to be carried out according to CEN/TS 16516)
23°C±2°C (test to be carried out according to ISO 16000-9)
23°C±0,5°C (test to be carried out according to UNI 717-1)
provided temperature in the room where the system is installed is conditioned to 23°C±0,5°C 23°C±1°C or to 23°C±2°C without stratifications

Relative Humidity conditions inside each test chamber
50% RH ±5% RH @ 23°C or 45%RH ±3%RH (UNI 717-1) in the test chambers.
Relative Humidity inside the test chambers may also be controlled to a value that can be set inside the limits "RH in the inlet air" up to 80% RH @23°C with an accuracy better than 3%RH @23°C

Air velocity
Air velocity control to a Set Point that can be set in the range 0,1 ÷ 0,3 m/s achieved through customized fans with brushless motors driven by a dedicated algorithm in the PLC/PC.
Test chambers required for formaldehyde emission test according to UNI 717-1 will be provided with q.ty 2 air velocity meters.

Inlet air (carrier gas) flowrate
Controlled by massic type flowcontroller, self adjusting, driven by the PLC (flow control not affected by possible pressure variations).

Inlet air diffusion system
One or more drilled cylindric diffuser inside each test chamber, designed to give proper carrier gas distribution in the chamber.

Sample withdrawal connections
Each chamber port will include q.ty 4 compression fittings for stainless steel tubings, 5 mm internal diameter, 6 mm external diameter. Q.ty 1 stainless steel tubing, 5 mm internal diameter, 6 mm external diameter will be supplied for each test chamber.

Air tigthness
Each emission test chamber are airtight and operated at a pressure slightly above atmospheric pressure in order to avoid uncontrolled air exchange with ambient air

A vent connection on each test chamber.

The chambers are installed, together with all other components of the system, on a self standing chassis, made in AISI 304 Stainless Steel and including wheels with brakes for easy movement inside the laboratory.

Port & Locking System
The test chamber ports will be wide open, with glass inspection windows. Port seals sponge Viton.
Each chamber port will also include a small shelf (e.g. to support sampling pump).
Each port will have a locking system and a safety interlock system (not for 1000 L and 6000 L) controlled by the PC/PLC (very important feature specially for the heated systems)
