Model RDH is the new rooftop, power-vented addition to the Reznor® line of Pre-Engineered Ventilation Air-Handlers (PREEVA™). Model RDH is available in 11 sizes from 75MBH to 400MBH. Each size is designed for a minimum 81% thermal efficiency and is available for use with either natural gas or propane. Model RDH rooftop, power-vented heaters are approved for commercial/industria
l installations in the United States and Canada by the ETL Testing Agency. Standard features include the Reznor® TCORE2® heat exchanger and single burner combustion system, a multi-try direct spark ignition with 100% lockout, pressure switch to verify venter flow, resiliently isolated venter motor, a high temperature limit control, and a centrifugal belt-driven blower capable of up to 3” w.c. of total external static pressure. Both the forward curved blower and the blower motor are factory installed on vibration isolation mounts. All published airflow data and sound data are supported by AMCA tested and rated airflow performance curves. The energy usage of the system has been designed to meet the current ASHRAE Standard 90.1 (maximum 1.2 bhp per 1000 cfm).
