About BTR Series

Aurum’s BTR Series is our replacement solution for outdated blow through fan coil units. By keeping the basic operations on this system, Aurum has revolutionized our fan coil unit to provide better energy efficiency, airflow and overall comfort. The slide in chassis is designed for an efficient, non-invasive replacement.

Retrofit Specifications


Aurum Manufacturing’s coils are manufactured with type L copper tubing, aluminum fins and stainless-steel side rails. All coils are brazed for maximum strength. Copper piping is insulated to prevent sweating in summer months. Prior to delivery all coils go through pressure tests and visual inspection. Coils are customizable for job specifications, and/or to meet building configurations. (ie. Allowing for an upwards supply feed).


The BTR series Chassis is assembled with 100% 20-guage stainless steel material. The interior of the chassis is insulated with closed cell insulation to prevent moisture buildup and reduce noise from vibrations.

The dimensions of the chassis vary with different BTR Series models, as can be seen in the dimensional chart below. VIEW CHART
