  • Intellisenc Greenhouse Controllers for control of CO2, Humidity and temperature

    Optimum and accurate CO2 level is important for effective and efficient plant growing. Too much CO2 creates diminishing return on expense and too little fails to utilize your capital investment. Optimum control of all facets of the growing environment results in high productivity at less costs. Plants need to be able to shed moisture to maintain their capacity to draw in nutrients from the soil. ...


  • Why is Humidity / Moisture Control Important in a Fuel Cell?

    The root of all of this is that Nafion membranes must stay hydrated to function properly. If they are not fully humidified the conductivity decreases and therefore more of the electricity is converted directly to heat before it leaves the membrane (I2R heating). If it gets too dry it basically stops functioning as a proton transporter. ...

  • New technologies for measuring the humidity of biomass

    Methods applicable to a great variety of solid biofuels In recent years, systems have sprung up which use near infrared X-ray (NIR) spectroscopy, radio frequency (RF) and microwave spectroscopy as alternatives to the traditional method of measuring humidity by weight difference in the fuel burner. What these methods have in common is that they can be used for a great variety of solid biofuels, ...

  • Intellisenc Building Air Quality Controllers control CO2, CO, VOC, O3, Humidity and temerpature.

    The quality of the air we breathe indoor (Indoor Air Quality, IAQ) is typically defined by the air chemical or gas composition and particulates. The sensors available today for sensing the gas composition of IAQ have many features and options. There is a wide application base for IAQ sensing with the most common being the regulation of HVAC ventilation systems for lower energy cost. Using an IAQ ...


  • Humid, corrosive and malodorous waste gases - Case Study

    Example: Production of bio-ethanol Similar tasks: Dryers, Fibre board industry The production of bio-ethanol - fermentation, distillation, pelleting and drying - generates odorous and humid waste gas. Upstream lamellar demisters reduce both drop formation - causing lower VOC destruction efficiency - and solid matters. The regenerative thermal oxidiser (RTO) ...

  • Stability and accuracy of CIRAS-2 Water Vapor (reference humidity): control option 1

    Summary Rapid large-scale fluctuations of carbon dioxide and water vapor, although unnatural and artificial in the plant world, are desirable attributes for gas exchange systems from a sampling efficiency standpoint. As PP Systems’ benchmark IRGA system for gas exchange and photosynthesis research, CIRAS-2 was designed for and expected to have exceptional response times to ...

  • Performance of a GAC and ultrafiltration hybrid process under high humidity and temperature conditions

    The performance of a granular activated carbon (GAC) and ultrafiltration (UF) hybrid process and changes in UF membrane properties were studied. This hybrid process reduced total organic carbon by 59 ± 12% and UV absorbance (UV254) by 88 ± 31%, with GAC accounting for 93 and 98% of total reduction, respectively. Selected pharmaceuticals and personal care products were reduced by 32–92% during the ...

  • Control water – control mold

    There is no single universal way to eliminate all mold growth.  But the single most effective method of controlling mold is to eliminate their source of moisture.  Moisture doesn’t just mean actual water; it can also be high humidity.  Few molds grow when the humidity is under 70%.  If they do, it is very ...

  • Coal fired power plant – humidity measurement during briquetting process

    Our subsidiary SWR Engineering has launched the M-Sens 2 sensor for the continuous measurement of humidity on solids of all kinds. It can ideally be used, for example in container outlets, conveyor belts, conveyor screws, mixers and conveyor dryers... Application An operator of a coal fired power plant uses brown coal for the ...

  • Performance characteristics of a Thin-film aluminum oxide humidity sensor - Case Study

    Summary A laboratory study was made of the performance of a miniature-size, thin-film aluminum oxide humidily sensor over a range of ambient temperatures from 0°C to 40°C and encompassing humidities from 40 to 78,000 parts per million by volume (ppm-v). Hysteresis and temperature effects of the sensors were obtained from tests performed at ambient temperatures 40°C, 25°C and ...

  • Control water – control mold

    There is no single universal way to eliminate all mold growth. But the single most effective method of controlling mold is to eliminate their source of moisture. Moisture doesn’t just mean actual water; it can also be high humidity. Few molds grow when the humidity is under 70%. If they do, it is very slowly. It is safe to say that you cannot stop mold growth until you stop the moisture. ...

  • Evaluation of AnnAGNPS and its applications in a semi–arid and semi–humid watershed in Northwest China

    The main goal of this study was to evaluate the performance of AnnAGNPS (Annualised Agricultural Non–Point Source Pollution Model) in simulating runoff, sediment loading and nutrient loading in a semi–arid and semi–humid watershed of an area of 1481sq km, located in Northwest China. This model was first calibrated and tested by historic monitoring data and then the validated model was used to ...

  • Controlling Mold Growth in Buildings Prevention and Control Strategies

      In background quantities, molds can be found everywhere-in air, water, our homes, our clothing and even on our pets. They are present in such small numbers that they don"t trigger reactions in humans, except in ultra-sensitive individuals. But, when molds find the right combination of ...

  • Corrosion Control in data Center

    CORROSIVE GASES: Small concentrations, serious consequences EU standard 2002/95/EC, or RoHS (Restriction of the use of certain Hazardous Substances in electrical and electronic equipment), which was implemented in July 2006, restricts the use of hazardous substances in the manufacture of electrical and/or electronic equipment. One of the banned substances is lead (Pb), which is used for soldering ...

  • CFD Analysis for NOx-Control in a Refinery

    Refineries are required by law to reduce the emission of nitrous oxides (NOX) to the atmosphere. Spray nozzles are key components in the gas conditioning equipment used to control the humidity and temperature of the gases, providing controlled volumes of liquid with predictable drop size and consistent spray coverage. Knowing these values is vital for the optimization of gas conditioning ...
