Direct Gas-Fired Heating

Overview

  • Model DG

    Model DG

    Model DG sets the standard for an efficient approach to tempered make-up air applications. Several intake and filtering configurations are available and optional evaporative cooling can also be selected. The DG model can be constant volume 100% outdoor air or configured to be variable air volume (VAV) through a VFD or EC motor option (Vari-GreenĀ®). With a VAV arrangement, it can provide seamless integration with Vari-Flow and MelinkĀ® kitchen energy management systems.

    • 800 to 15,000 cfm and 2 in. wg
    • Up to 1,600,000 BTU/hr.
    • Optional evaporative cooling
    • ETL listed


  • Model DGX

    Model DGX

    Model DGX is a highly configurable direct gas-fired heating and cooling system that incorporates a modular design for maximum flexibility. In addition to constant volume 100% outdoor air operation, recirculation and variable air volume options are also available. The DGX can be configured with a forward-curved or backward-curved supply fan allowing for both belt driven or direct drive arrangements.

    • 800 to 48,000 cfm and 4 in. wg
    • Up to 4,800,000 BTU/hr.
    • Cooling options: packaged direct expansion, split direct expansion, chilled water, or evaporative cooling
    • ETL listed


  • Model TSU

    Model TSU

    Model TSU is a configurable, direct gas-fired heating make-up air unit that is that is capable of delivering larger volumes of air than the DGX. In addition to constant volume 100% outdoor air operation, recirculation and variable air volume options are also available.

    • 33,00 to 64,000 cfm and 3 in. wg
    • Up to 7,000,000 BTU/hr.
    • Optional evaporative cooling
    • ETL listed


  • Model VSU

    Model VSU

    Model VSU is a vertically configured direct gas-fired heating make-up air unit that offers a wide range of CFMs. The vertical configuration removes the concern of equipment weight loading from the roof and offers a more simplified means of installation. Ground level filters, dampers, and controls also greatly simplify equipment start-up and maintenance.

    • 800 to 64,000 cfm and 3 in. wg
    • Up to 7,000,000 BTU/hr.
    • ETL listed
