The Model S Coil

Features and Benefits

The Model S Coil

The Model S unit heater features a unique single tube serpentine coil.This compact, efficient coil has piping connections at the back for added space savings, convenience and appearance. Model S single circuit coils use threaded connectors at the back of the unit.

The Model P Motor

The Model P motor is mounted below the top panel inside the heater casing. This reduces unit height and permits the unit to be installed closer to the ceiling for added headroom.

Compact Design

Trane designed Model S and P propeller unit heaters for easy installation and low maintenance.TheTrane Sigma-Flo®fin design allows coil size to be reduced while maintaining high capacity performance equal to larger flat-fin coils. Reduced size and weight makesTrane unit heaters easy to handle and install.

Rectangular Draw-Thru Coils

The Model P draw-thru coils use short lengths of steel pipe threaded for supply and return connections.These features make piping connections much easier for the installer.
