Features and Benefits

Model P

Simple Hanger and Piping Connections The Model P uses weldnut type hanger connections, while the Model S uses a nutsert type hanger connection. Hanger rods screw easily into threaded anchor points. Piping connections can be made equally as easy. Model P units provide threaded connections for inlet and outlet, top and bottom.

Model S

Fully Accessible for Easy Maintenance Model S and P unit heaters are fully accessible for maintenance. Only four main bolts are needed to disassemble the Model P. And when quick access is needed, the Model S features a one-piece back that can be easily removed and slid over pipes without breaking connections.

Motors can also be easily removed. Both units feature totally enclosed motors with thermal overload protection. As an added benefit, Model P fan-motor assemblies can be conveniently removed from below through the fan outlet.

External Couplings

The Model S provides threaded connections for supply and return on the back of its casing. In addition, back connections reduce the amount of space needed for installation.
