Example 1: OHS040HGFC, is a CeilAir Overhead System with 40,000 Btu/h capacity, Horizontal Discharge, a Glycol-
Cooled refrigerant circuit, and optional Free Cooling.
Example 2: OHS072DAHUSF, is a CeilAir Overhead System with 72,000 Btu/h capacity, with Dual Circuits, in an Air
Handling Unit configuration, and with Same-Face Air Pattern.
Terminology. This manual will occasionally use forward slashes (/) to indicate a range of capacities, e.g., “models OHS-
012/040,” which includes OHS models with capacity 012 through 040.
Cooling fluid. CeilAir units utilize refrigerant (AHU, AR, or AS), chilled water (C), water (W), or glycol (G).
Refrigerant type. CeilAir units using refrigerant may be charged with R407C or R410A.
Condensers and condensing units. STULZ condensers and condensing units are documented in our Heat Rejection
Engineering Manual.
Pump packages and drycoolers. STULZ pump packages and drycoolers are documented in our Glycol Systems
Engineering Manual.
