Introduction

The Industrial Designed Model P Unit Heater

The Clean-Line Appearance of the Model S Unit Heater

The square, compact design of the Model P and rectangular Model S allow easy handling and installation. In most cases, only one person is needed to carry a unit. And because both feature compact Sigma-Flo®fins they’re lightweight, making them easy to hoist and put into place.

What’s more, the Model P can be stored standing on end.This means several units can be loaded on a single skid for moving from one point to another.Trane maintains a complete stock of both Model P and S units that are available to ship anywhere in the United States.

Yet, the benefits of this compact design go beyond ease of installation.They continue with attractive styling.The Model S unit’s simple, clean-line symmetry and the Model P unit’s classic modern shape enhance any industrial facility.
