AT-Series Selection Guide

To create a complete air turnover unit, choose one base unit and one burner/manifold package using the tables on the following pages. Prices apply for natural gas or LPG units.

1. Choosing A Base Unit Package

Base Unit Package choice is based on model choice. First locate the correct set of tables on the following pages which corresponds to the required type of unit. Locate CFM and MBH requirements on the appropriate set of tables to determine the unit model. If more than one model is applicable, choose the smaller model.

Btu/h Output Required = CFM * 1.08 * Temperature Rise

MBH = Btu/h / 1,000

2. Choosing A Burner/Manifold Package

Choose Burner/Manifold Package based on input, burner type and insurance requirements. Choose a Burner/Manifold Package that can fulfill the maximum output of the model. Note that burner INPUTS are listed rather than outputs.

Burner Input = Burner Output / .8
