Beschreibung

Reznor's SDH is the new separated-combustion addition to the line of Pre-Engineered Ventilation Airhandlers (PREEVA). Available in 11 sizes (75MBH to 400MBH), each size is designed for a minimum of 81% thermal efficiency and is available for use with either natural gas or propane.

Model SDH separated-combustion heaters are approved for commercial/industrial installations in the United States and Canada by ETL Testing Agency. All published airflow data and sound data are supported by AMCA tested and rated airflow performance curves.

Complies with ASHRAE Standard 90.1

Note: Model SDH separated-combustion units require installation of either a horizontal or vertical vent/combustion air kit that includes a specially designed concentric adapter box. The unique box design allows for only one building penetration for both the flue outlet and combustion air inlet.
