project background
In order to promote the construction of ecological civilization, implement the Special Implementation Plan for the Rectification of Volatile Organic Compound Pollution in Key Industries in Hebei Province, strengthen the operation and management of volatile organic compound emission control facilities, and meet the growing demand of the people for a beautiful ecological environment. Emery Technology, in collaboration with industry elites such as the University of Science and Technology and fifty-four institutes, has carefully developed an online detection VOC over limit alarm sensor device (VOC over limit alarm) that is widely applicable to fixed pollution sources and unorganized emissions in various industries such as chemical and rubber. Intended to ensure emissions (exhaust pipes and chimneys) meet standards through improved monitoring technology.

Scope of use
The AMLVOC series VOC over limit alarm sensing device from Emery Technology is mainly used for emission sources with emission rates less than 2.5kg/h or exhaust volumes less than 60000m3/h; Especially suitable for monitoring unorganized emissions after collection and treatment; Unorganized emission workshops, factory boundaries, and other places that require excessive monitoring can retain samples for exceeding the standard.

system composition
Alarm based online monitoring system analysis host;
Gas analysis sensing device;
Gas sampling device (optional pre-processing);
Excess sample retention unit (optional);
Temperature, pressure, flow and humidity measuring instrument (optional);

Product advantages

Choosing Emery means choosing:
VOC over limit alarm that complies with national and local standards, specifications, technical requirements, and policies;
It is difficult for peers to achieve VOC over limit alarms that can be installed by enterprises in one go and reduce rectification;
The supply price is 10% lower than the average price of peers, with a lifetime free software upgrade for one investment, while peers only offer free software upgrades for one year.
