Features & Benefits: Overview
Trane propeller unit heaters feature
the largest selection of standard
sizes from any line in the industry. In
fact, vertical Model P and horizontal
Model S unit heaters provide
enough ‘off-the-shelf’ selections to fit
almost any application.
The versatile two-in-one Model P is
available in 15 sizes with capacities
from 41.3 MBh to 705.6 MBh. The
companion standard and bypass
Model S is available in 23 sizes with
the capacities from 8.0 MBh up to
360 MBh. Both are designed for
durability, attractiveness and
compactness. These features
combined with economical
operation, give strategically sized
Trane unit heaters an edge
unmatched by any other
manufacturer.
Two Units in One – The
Versatile Model P
The Trane Model P can be quickly
field converted from standard to low
final temperature PL design simply
by removing the unit’s patented
knockout air ports. This unique
two-in-one design allows the
stocking wholesaler to cut
inventories in half and still meet
most customer application
requirements.
Patented Trane louver cone diffusers
allow directional flexibility of heated
air.
The Space Saving Model S
The Side Connection type Model S
unit features functional styling in a
space-saving design. This hot water
unit heater is available in capacities
from 8.0 to 35.9 MBh and is ideal for
applications where clearance is
limited.
The Heavy-Duty Model S
The versatile Header-Type unit can
be used with either steam or hot
water systems and is available in
capacities from 18.0 to 360.0 MBh.
Rugged cast brass headers and
mechanically bonded fins provide
reliable heating to suit a wide variety
of solutions.
Note: Vertical louvers are available
for all Model S units to put
heat where it’s needed.
