Ebac RM4500-H Whole House Ducted Dehumidifier – 150 PPD, WiFi Smartphone Monitor

Ebac RM4500-H Dehumidifier – 150 PPD with Smartphone Monitoring and Electronic Humidistat

The Ebac RM4500-H adds smartphone-compatible monitoring and an electronic humidistat to the RM4500's 150 PPD DualCool HGR extraction platform. Restoration supervisors track run hours, unit status, and performance data remotely — reducing site visits for status checks during multi-day drying operations. The electronic humidistat maintains target humidity automatically, stopping and restarting the unit to preserve its operating life during the drying-out phase when ambient humidity drops below the setpoint.

Remote Monitoring in Active Restoration

Restoration companies managing multiple simultaneous jobs benefit from the RM4500-H's smartphone interface when technicians cannot check every unit in person daily. The data logging captures drying progress over time — humidity curves and run-hours per job that support insurance documentation of the drying process. The electronic humidistat cycles the unit automatically at the target setpoint, preventing over-drying that wastes energy and can stress building materials.

Restoration Billing and Compliance

At 150 PPD the RM4500-H falls above the 85 PPD threshold — bill as Xactimate WTRDHM>XL. ETL and CETL listed. The DualCool reverse-cycle defrost system operates at 37°F minimum. Note: the spec table references 230V/50Hz metrics — the US unit operates at equivalent PPD on 115V/60Hz; confirm with the spec sheet for exact 115V output figures.
