    Piping & ducting solutions for the HVAC industry

    The heating, ventilation, and air conditioning industry refers to the technology of indoor temperature control. A sub-discipline of mechanical engineering, HVAC systems are crucial in the design of residential as well as commercial structures. These systems control the temperature, and also the quality of the air that gets circulated, by replacing or exchanging the air in a particular space. Heating, cooling and ventilation systems require high-quality, precision-engineered parts, such as those manufactured by PROCO Products. PROCO operates worldwide, and maintains one of the largest product inventories in North America.

    Cement

    MEGTEC's extensive scrubber experience applies to the cement manufacturing process for the effective control of SO2 and HCl by the injection of lime slurry. Our customers can achieve up to 90% reduction of SO2 and 98% reduction of HCl using microfine or standard lime. The TurboSorb Spray Dryer Absorber (SDA) can often retrofit into an existing gas conditioning tower, or downcomer duct, to avoid the high cost of new capital equipment.

    Iron and Steel

    SoniCool™ Evaporative Gas Cooling & Conditioning uses a finely atomized water spray to cool EAF, BOF off-gases from over 2,400°F (1,315°C) to as low as 240°F (115°C), protecting ductwork and downstream air pollution control equipment from high temperature and sparks, while providing rapid cooling for dioxin and furan control. By optimizing humidity levels, SoniCool™ helps electrostatic precipitators. The water spray completely evaporates while cooling gases. There is no free water and no troublesome deposits in ducts, towers or hoppers. Turbotak rugged nozzles are made to the exact requirement, and ideally suited to the harsh conditions in the steel manufacturing process while still producing ultra-fine sprays, with precise control of dropsize and spray coverage.

  • Primary air control for coal-fired power plants

    Power Generation Combustion Air Measurements: The need for accurate, repeatable & reliable combustion air measurements in power generation plants is critical to efficient operation and safety throughout the entire facility and processes. Coal-fired power plant applications pose a number of challenges to obtaining these critical flow measurements includ¬ing large ducts, limited metering runs, poor velocity and temperature profiles, high vibration, temperatures up to 750° F and dirty `Fly Ash` laden air.

  • Secundary air flow measurement for power generation industry

    Secondary Air Flow Overview: The need for accurate, repeatable & reliable combustion air measurements in power generation plants is critical to efficient operation and safety throughout the entire facility and processes. Accurate secondary air flow measurement to the burners is critical for maintaining the proper air to fuel ratio, result­ing in more complete and stable combustion, better performance and lower emissions. Coal-fired power plant applications pose a number of challenges to obtaining these critical flow measurements including large ducts, limited metering runs, poor velocity and temperature profiles, vibration and high temperatures.

    Marine monitoring solutions for the SO2/CO2/NOx monitoring

    Process control of a SO2 scrubber on a ship is a challenge due to wet and corrosive gases. In such environment, extractive gas sampling systems require high levels of maintenance in order to operate correctly. OPSIS monitoring system solves this by using an optical, non-contact, cross-duct technique. A light beam is sent across the duct or stack to be measured, and the captured light is sent through an optical fibre cable to an analyser. The analyser measures SO2, CO2 and NOx concentrations using UV and IR absorption, approved reference methods.

  • Stack Testing for Power Generation Plants

    POWER GENERATION INDUSTRY: Conducted detailed measurements of volumetric flow, oxygen, and carbon dioxide levels in huge main ducts in the Economizer Outlet, Air Heater Inlet, and Exhaust Stack locations in order to evaluate overall plant and control system performance

    Fire detection solutions for the oil rigs

    The worse event that can befall on off shore oil rig is fire. The Model 125 is a smoke monitor designed to operate in hazardous areas, especially in oil rig air conditioning and ventilation ducts. The electronics are contained in an explosion proof container rated as EEX de II B T5; the sensing head uses fibre optic cables to transmit the near infra-red light to a reflector where it is returned to another fibre optic cable. The light level is then monitored by a photo-electric cell. The Model 125 gives an output in opacity which is transmitted to the rig safety systems.
