This system has been developed for the same important Belgian Centre active in scientific and technical research, in supplying technical information, assistance and consultancy in the constructioon sector.

Main technical features

4 independent test chambers, with 250 L volume each

air filtration group on the inlet purified air

measure of T and RH in the distribution chamber

control of relative humidity of the carrier gas sent into the 4 chambers to a fixed value 50%RH ±5%RH

control of temperature of the carrier gas sent into the 4 chambers to a fixed value 23°C ±2°C

measure and recording of flowrate, temperature, relative humidity, air velocity in each chamber

separate air flowrate control capability on each test chamber, massic flowmeters, nominal flowrate range:
0 ÷300 NL/h, accuracy ±1% F.S.

separate air velocity control for each test chamber, 0,1 ÷0,3 m/sec, controlled by PLC through the fan rotation speed

separate and independent temperature control in the 4 test chambers; control range 23°C÷50°C ±2°C; all
the chambers are independently thermally isolated

Vent system on each test chamber including 1 stub, a flexible hose and a manual interception valve; the 8 vent hoses are fitted into a single hose connection on the rear of the system

Air purge system in all the test chambers. The air purge is completely automatic in chamber 1, driven by the PLC through a 1000 nL/h massic flowmeter; the air purge in chembers 2, 3 and 4 is manual, through interception valve and factory preset flow adjusting valve on each chamber.

VOC Emission Test Chambers

 Copertina 636x534

Chambers for volatile organic compounds (VOC) emission tests according to international standards as ISO 16000-9, UNI CEN/TS 16516, GEV testing methods, UNI EN 717-1, ASTM D5116.

CLR Srl has designed and manufactured a number of systems for VOC emission tests according to emission test chamber method.

We can design and manufacture different systems, according to customer requirements, not only concerning number and dimensions of the chambers, but also regarding the type of measures and controls, thermal isolation, air velocity, relative humidity and temperature adjustment inside the chambers etc.

A "typical" VOC testing system made by CLR includes a number of testing chambers varying from 1 to 8 or more, according to customer specification, having the volume required by the customer, that can range from 50 liters (or less) to 1 cubic meter (or more) (volume also depends on the number of chambers). Test chambers are made of internally electropolished stainless steel and have wide open ports for easy specimen insertion.
The chambers are assembled on a self-standing chassis, mounted on wheels c/w brakes for easy movement; the chassis also includes all required equipments and control instrumentation.
The latest systems we have supplied also include air filtration system for carrier gas.
A 3-way motor operated valve, controlled by the PLC, allows to partialize the amount of carrier gas that is sent to the humidification chamber.
The humidification chamber (including an ultrasonic humidity generator), is connected to a reservoir tank c/w level switch for automatic water refilling through a pump (supplied). The demi water refilling is automatically controlled by the PLC.
Before entering the test chambers the humidified gas passes through a distribution chamber where temperature and relative humidity are measured and recorded on a continuous basis. The measure of RH is used by the PLC for RH control in the carrier gas that is sent to the test chambers.
Air flowrate, temperature, relative humidity and air velocity are measured in each test chamber and recorded on a continuous basis.
Some systems have thermally insulated chambers and separate control of temperature in each test chamber.
One system has separate control of relative humidity in each test chamber.
Air velocity is separately controlled in each test chamber by the PLC that adjusts the fan rotating speed on the basis of the feed back signal for the air velocity meter.
All the measured values are sent to the PLC that manages the control of relative humidity in the distribution chamber, carrier gas flowrate and air velocity separately for each chamber; controls the water level in the humidification chamber and in the water reservoir. The PC acts as HMI and displays T, RH, flowrate and air velocity values of each chamber (actual values and historical trends).
The PLC records pertinent data of each test and at the end of each test provides a “.csv” file that can be easily downloaded on an USB key. An Ethernet connection for remote communication (up to the customer) is also provided.

Maintenance

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 ternm test, would lead to a loss of days of work.
