    Gas monitoring instruments and systems for compressed breathing air

    Compressed breathing air is subject to strict limits of harmful contaminants defined in European standard EN 12021 and various defence standards such as DEF STAN 68-284 issue 3. The testing interval of breathing air compressors and associated equipment is 3 months and gases tested include carbon monoxide, carbon dioxide and oil vapour defined as hexane and heavier hydrocarbons. EN 12021 covers underwater applications including self-contained open circuit compressed gas breathing (SCUBA) and compressed gas line breathing (hard-helmet diving), respiratory equipment used on ground for escaping from toxic atmospheres and for working in contaminated atmospheres. It also covers breathing gas for hyperbaric operations and synthetic air. While EN 12021 does not cover aerospace applications, the British MOD publication DEF STAN 68-284 and its counterparts in other countries cover also the breathing gases used in aviation.

    Waste water treatment plants Screening area: stripping

    Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. To ensure the safety of operatives in the screening building/area of waste water treatment works an H2S analyzer has been installed in the main building to complement the protection provided by individual monitors. Chromatographic measurements show that other sulfurous compounds including Methylmercaptans are present in the air in addition to H2S.

    High quality gas sensor solutions for building and IAQ

    Precise measurement of air quality. The carbon dioxide content of room air gives a measure of the air quality, especially as it relates to the health and comfort of the people occupying the building. Air quality can be adversely affected by increased levels of carbon dioxide, carbon monoxide, volatile organic compounds (VOCs), particulates, or bacteria. Increased ventilation reduces the level of all of these unwanted contaminants. Measuring the CO2 concentration provides an economical way of ensuring that there is sufficient air circulation and prevents over-ventilation which can add unnecessary heating or cooling costs.

    Indoor Air Quality Monitoring

    Accurate control of critical indoor environmental parameters is not only essential for the well-being and comfort of building occupants, but also has a major impact on energy efficiency. A multitude of parameters can affect indoor air quality (IAQ) from gases such as carbon dioxide (CO2), carbon monoxide (CO) and volatile organic compounds to particulates, humidity and bacteria such as legionella. CO2 is one of the greatest variables affecting indoor environmental quality since it is produced by people occupying the building. CO2 production is a function of the number, size and activity levels of the people present in the building. Local concentrations can therefore vary dramatically – for example when a meeting room is occupied, or while workers are on lunch or coffee breaks. Excess CO2 levels can lead to tiredness and a lack of concentration and can contribute to the symptoms of Sick Building Syndrome such as headaches, eye, nose and throat irritation, itchy skin and nausea.

  • PLAZKAT systems for treatment (removal, neutralisation) of smelly substances from the air

    PLAZKAT Aero units are used to neutralize bad smells from waste treatment facilities, caused by the presence of sulfur and nitrogen compounds - hydrogen sulfide, mercaptans, and ammonia. Urban waste treatment facilities, local waste treatment systems in factories, pumping stations in waste water treatment systems are characterized by a strong smell of sulfur and nitric compounds.

  • Indoor air quality (IAQ)

    Indoor Air Quality (IAQ) refers to the effects on human health of various factors that are properties or constituents of the air we breathe and generally indoors. Very briefly, we can say that a series of events led to the finding that many chemical or biological substances can be inhaled which can cause various health problems which start as simple disorders but lead to serious illnesses. Of similar importance are several natural parameters of the so-called `interior environment`.

  • Air cleaning system for the higher education areas

    Dynamic Air Cleaners are an ideal indoor air quality solution for schools, colleges and universities. Without sacrificing budgets, higher education institutions can utilize these highly-versatile air cleaners to lower energy costs and establish greener, healthier learning environments for teachers and students. A report from The American Institute of Architects, The Redford Center, ICLEI USA – Local Governments for Sustainability and the U.S. Green Building Council (USGBC) estimates inefficiency costs the average school $100,000 each year. The report also states 14 million students attend schools considered below standard or dangerous, with more than 15,000 schools having air deemed unsafe to breathe. Generating a return on investment in three to five years, Dynamic Air Cleaners remove dangerous airborne particles that other air cleaning systems miss, including odors, smoke, bacteria, allergens, fine dust, mold and pollen, without producing any harmful ozone.

  • Air cleaning system for the office buildings

    According to the U.S. Environmental Protection Agency, we spend over 90% of our time indoors. Much of this time is spent in our offices. Studies show that cleaner air in office buildings can improve productivity and reduce absenteeism. High Efficiency Air Cleaning – Dynamic Air Cleaners remove dangerous airborne particles that other air cleaning systems miss…including odors, VOCs, smoke, bacteria, allergens, fine dust, molds and pollen…without producing any harmful ozone. When properly applied Dynamic Air Cleaners can have a significant impact on removing odors from outside air as the air comes through the ventilation system.
