Targeted FAQs

  • Should I use a humidistat control with the HRSM?

    Humidistat controls work best for applications requiring 80% RH or less. If you need to maintain RH above 85%, do not consider using a mechanical humidistat control.

    If you are interested in evaporative cooling and have thermostatically controlled exhaust fans, using a humidistat control is a great choice. The two independent systems will work very well together, for cooling as well as for providing a maximum set point for relative humidity control.

  • Can I use a metering pump with the ORSM?

    Connecting the ORSM to a metering pump and product supply is an ideal set-up; however, we do not supply the pumps or any odor control products. Some pumps are fairly expensive, and we recommend working directly with a pump supplier to ensure that you purchase the correct size for your application.

  • How much pesticide should I use in a CRSM?

    Typically, the same amount as you would use in a back-pack sprayer or any other type sprayer. The only difference in ultra low volume systems is the use of less water to disperse the same amount of chemical pesticide product. The CRSM comes with an easy-to-follow dilution chart that can be found on page 8 of the CRSMs operator's manual.

  • Can I achieve evaporative cooling indoors?

    In most cases, you cannot create evaporative cooling in an indoor environment; however, if there’s a strong ventilation system available, and a significant increase in humidity would not have a negative impact, then it is possible.

    Every gram of water that evaporates absorbs 536 calories of heat, producing humidity that builds quickly. Without ventilation, cooling effects attenuate quickly as the humidity builds. At 100% RH, no cooling occurs.

  • How do I know when the environment is near 100% RH?

    For best results, measure RH using a quick responding digital humidity indicator with a range up to 100%. Please note: the device should not be kept inside the application room for extended periods of time.

    If you want a less expensive way to measure RH, or want to monitor the humidity in the application area for extended periods of time, then place a block of aluminum and a block wood next to one another. The aluminum will attract condensation at 85% RH and the block of wood will attract condensation at 100% RH. So maintaining a wet block of aluminum along with a moist block of wood is a good indicator that you are near 100% RH.

    • If the block of wood gets wet, rather than moist, then you will know that the area is likely being over-humidified, with the possibility of product damage occurring. In this case, a decrease in fogging output is needed.
    • If the block of aluminum is dry, then you know that the area is below 85% RH and an increase in fogging output is needed.
