Purpose
This article explains how to identify and convert GI model naming into the equivalent General Airstage Applied model naming format.
Use this guide when reviewing technical documents, spare parts references, service requests, or customer enquiries where the unit may be referred to by either the older GI model type or the newer General Airstage Applied model type.
Model Name Structure
The model name is made up of three main sections:
| Section | Meaning | Example |
|---|---|---|
| Unit Type | Identifies the specific type of unit | AAC |
| Version | Identifies the unit version or configuration | IK/A/WP/SSL |
| Size | Identifies the unit size or capacity | 218P |
Example model format:
AAC/IK/A/WP/SSL 218P
This can be broken down as:
- AAC = Unit type
- IK/A/WP/SSL = Version
- 218P = Size
GI to General Airstage Applied Model Conversion
The first part of the model name identifies the specific type of unit. The table below shows the GI model type and the equivalent General Airstage Applied model type.
| Unit Type Description | GI Type | General Airstage Applied Type |
|---|---|---|
| Aircooled units with axial fans | CHA | AAC |
| Aircooled units with radial fans | CRA | ARC |
| Watercooled units | CWW | AWC |
| Condenserless units | MEA | AME |
| Condensing units with axial fans | MHA | AMH |
| Condensing units with radial fans | MRA | AMR |
| Remote aircooled condensers | RCA | ARA |
| Dry-Coolers | RCW | ARW |
| Remote hydronic modules | MR | MH |
How to Interpret the Model Code
When reviewing a model number, focus on the first three letters.
For example:
CHA in GI format converts to AAC in General Airstage Applied format.
Therefore, a GI model beginning with:
CHA
should be interpreted as:
AAC
in the General Airstage Applied model range.
Example
GI Model Reference
CHA/IK/A/WP/SSL 218P
General Airstage Applied Equivalent
AAC/IK/A/WP/SSL 218P
Only the first section changes from the GI unit type to the Airstage Applied unit type.
The remaining sections of the model name generally continue to describe the version and size:
| Section | GI Example | Airstage Applied Example |
|---|---|---|
| Unit Type | CHA | AAC |
| Version | IK/A/WP/SSL | IK/A/WP/SSL |
| Size | 218P | 218P |
Internal Handling Guidance
When a ticket, quote request, spare parts enquiry, or service request references a GI model:
- Identify the first part of the model number.
- Match the GI type to the equivalent General Airstage Applied type.
- Confirm the version and size remain consistent.
- Use the converted Airstage Applied model when searching internal documentation, spare parts records, or technical references.
- If the model cannot be matched using the table above, escalate to Technical Support before confirming parts or technical advice.
