Reznor Reznor® PDH Series Indoor, Power-vented Pre-Engineered Ventilation Airhandler Model PDH400A

Model PDH is the new indoor, power-vented addition to the Reznor® line of Pre-Engineered Ventilation Airhandlers (PREEVA™). Model PDH 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 PDH indoor, 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 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 (@ 1.2bhp per 1000cfm). Operation is controlled through an integrated circuit board. The circuit board monitors heater operation and has LED diagnostic indicator lights to identify abnormalities in heating control functions. Optional features include three newly designed, factory assembled, modular sections- a draw-through cooling coil cabinet module with either chilled water or DX coil; an inlet air mixing box module with a variety of configurations and damper options; and an evaporative cooling or electronic air purifier module. A complete heating and cooling advanced digital control package is available in addition to common industry standard analog heating only and makeup air controls.
