    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.

    Disaster and Epidemic Response

    Anywhere there is a large gathering of people, respiratory infections can be acquired due to exposure to airborne pathogenic microorganisms. To help prevent the spread of diseases the Center for Disease Control (CDC) recommends that potential problem areas be isolated and the air purified by portable, HEPA air filtration equipment. OmniAire and OmniAire PAC portable HEPA air filtration machines provide a clean air supply necessary to protect the public in gathering areas such as schools, emergency shelters or temporary healthcare facilities. To comply with CDC guidelines to prevent the spread of disease and contamination of sensitive areas, OmniAire HEPA air filtration machines are commonly used to: -Create a negative air pressure in isolation containment -Supply purified air for required air changes (ACH) -Sanitize airflow in operating and patient’s rooms -Purify air in waiting rooms and public areas -Prevent contamination in compounding pharmacies

    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.

  • 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.

  • Smoke generator device for leak testing & building envelope testing

    Smoke is the perfect medium for discovering where leaks are and how big they are! Filling a `leaky` building, ductwork, pipes, aircraft or containment area with smoke and ideally adding a small amount of pressure to the area being tested, will result in a visible discharge of smoke and, simply put, the greater the volume of smoke, the bigger the leak. After Concept developed a bespoke system for their aircraft testing requirements, a spokesperson for the RAF commented: `The use of smoke as a means by which to detect cabin pressurisation leaks has been shown to be extremely effective and is unquestionably superior to any alternative detection method used to date!`

  • Air cleaning system for the retail

    Of the almost 5 million commercial buildings in the U.S., retail buildings account for the largest energy bills and are responsible for the second largest percentage of greenhouse gas emissions, according to the EPA.  There are a growing number of retail companies that are embracing the principles of sustainability, taking actions that are tangible, measurable and meaningful in reducing the use of scarce resources and improving the efficiency of their businesses.  For a large company, this can add up to millions of dollars in annual savings.
