• ASHRAE Standard 62, Ventilation for Acceptable Indoor Air Quality, defines the minimum outdoor air ventilation rates required to achieve acceptable indoor air quality.  This standard, which is referenced in part or whole by all building codes in the United States, recommends that outdoor air quantities be increased from 5 cfm per person to 20 cfm per person (in an office environment) to avoid adverse health effects.  Although most owners, architects and engineers recognize the benefits of bringing in more outdoor air, many are concerned about the impact on equipment and operating costs.

    SEMCO Modular Climate Changer (hereinafter, SMCC) provides the solution to the ASHRAE 62 mandate.  It precools and dehumidifies the outdoor air during the cooling season and preheats and humidifies the outdoor air during the heating season.  As a result, the outdoor air quantity can be increased from 5 to 20 cfm per person without increasing energy costs.

    As importantly, the first cost savings associated with the reduction in chiller and heating/humidification capacity typically pay for the added cost associated with the installation of the total energy recovery equipment.
    The SMCC Series Wheel technology affords a number of benefits:

    • Independently certified wheel performance. 
    • Equal latent and sensible heat transfer.
      • Highest effectiveness for fast payback, given the size of equipment.
      • Field adjustable purge section.
    • Wheel independently certified to pass NFPA 90A requirements for flame spread and smoke generation based upon ASTM E84 fire test method.
      • Reliable operation.
      • Low maintenance.
      • Low operating costs.
      • Long life expectancy of wheel media.
      • Can be applied where stationary heat exchangers cannot.
      • Reduced utility peak loads.
      • Lower first cost on new installations.
      • Greatly improved air quality.
      • Increased outdoor air quantity without increasing the heating/cooling plant.
