Units are also available for installation indoor with ducted condenser coils with centrifugal blowers.

    The cooling provides the highest efficiencies (EER) in the industry by utilizing digital scroll compressors, digital superheat controller, electronic expansion valves, and variable speed condenser fans. Cooling has been energy performance verified by Intertek / ETL to standard CSA C746:2006 and AHRI 340/360:2007

    Digital scroll compressors with rotolock valves set on vibration isolators within a compressor vestibule adjacent to the evaporator header. All refrigeration valves and controls are also located in the vestibule. All access doors are double wall hinged with handles for easy access for service and maintenance. Units are provided with winter filter sections which provide for year round filtration in colder climates where summer filters freeze in winter months.

  • Indirect Fired Make-up Air Units w/ Integral Packaged DX Cooling

  • Desiccant Dehumidifiers

    The desiccant dehumidification wheel is designed to provide maximum moisture removal with minimum pressure drop, and provide another tool to control humidity effectively and efficiently particularly in the low humidity range.

    They are widely used in the humidity control of ice rinks, refrigerated warehouses, and supermarkets. Standard product offering ranges from 2,000 to 35,000 CFM, however larger systems are available.

    All the units are customized for specific requirements and can be integrated into a complete custom HVAC unit with integral DX cooling and with additional indirect fired heating.

    Reactivation is available in either 25% or 50% of the wheel. The 50/50 split is used when integral DX cooling is incorporated as part of the system and the condenser heat (heat of rejection) is used for reactivation of the wheel. The wheels are available with 2 types of desiccant, Silica Gel (WSG) desiccant and specialty Molecular Sieve (LT3) desiccant. WSG is more widely used, and LT3 for low inlet % relative humidity and when a low dew point is required. The humidity controller w/ digital display is provided to very accurately control the humidity removal within the conditioned space.
