Thermal-XR Treatment – Power Logging – Berowra RFS Headquarters
CASE STUDY
Introduction
This report summarises the power used at the Berowra RFS Headquarters building before and after Thermal-XR, a thermally conductive coil coating was applied to the air conditioning units installed at the site.
Five Daikin 30kw heat recovery units are installed on the site, and the applicator has indicated that all units had the coating applied.
The report is based on data logged by Mt Colah Electrical, using an AEMC Model 8335 instrument to record power data including Amps, voltages and wattages for the complete building. The data provided covers the period from the 12th November 2019 through to the 4th December 2019 with the coil coating applied on the 22nd November.

Thermal-XR Coil Treatment
Thermal-XR is a condenser coil coating that is intended to recover/improve heat transfer of corroded condenser coils, the application process involves:
- Cleaning the condenser coils (the applicator has indicated that the coils, prior to treatment were “well serviced and relatively clean”.
- Pre-treating the coils
- Applying the Thermal-XR coating
The treatment is expected to optimise the heat transfer properties of the condenser coils thereby improving operating efficiency, lowering energy consumption and peak loads. The coating supplier has indicated that the coating is also “intended to provide ongoing corrosion protection and thereby extend the life of coils by at least ten years, with maintenance”.
Daily Power Usage
The energy usage data provided, was filtered to remove days for which the logged data did not cover a full 24hr period, this data was then plotted along with weather data for the closest BOM data site (Terry Hills, Sydney).

The above diagram and chart below show a reduction in energy usage between the pre-treatment (13 Nov – 18 Nov) and post treatment (25 Nov – 3 Dec) periods (coating applied 22nd November) even though the operating conditions might be considered to be slightly more onerous in the post treatment period – slightly higher temperatures and humidity.
Averages
Peak Currents
Prior to treatment occurring a safety protection device (SPD) was tripping, after treatment the device did not trip during the monitoring period. The graph below includes all data monitored and provides the peak amps measured on each day.
