Advantage chiller model numbers encode a series, a capacity, and often a configuration code (single- or dual-zone, air- or water-cooled, and so on) in one string. Knowing the series prefix tells you the general product line before you ever look up an exact spec sheet.
The table below lists the series prefixes used across the Advantage product lines and what each one covers in general terms. Every series has its own page with a model-by-model listing and a page for each part number; this index is the shortcut from a prefix to the right one of them.
If you already know a part number from an old quote, nameplate or spec sheet, send it to us directly and we'll confirm the specs and current equivalent. If you're starting from scratch, the Chiller Selection Guide will get you to the right series and capacity by heat load and required temperature, which is a faster path than guessing at a part number.
The leading letters of an Advantage model number, naming the product line before the capacity and configuration codes that follow. Read it first and the right spec sheet is one click away.
Prefixes by Product Line
Find the prefix on your nameplate or quote, then follow the line to its series page.
| Series Prefix | Product Line | Typical Range |
| M1 | Portable chillers | Small single-phase portable units |
| MG / MGD | Portable chillers | Portable units, single and dual-circuit variants |
| Titan | Central chillers | Indoor/outdoor central chiller packages |
| OACS | Central chillers | Outdoor air-cooled central chillers, single and dual zone |
| APT-RC | Central chillers | Remote-condenser central/portable configurations |
| WPT | Central chillers | Water-cooled process chiller packages |
| BC / BG | Glycol chillers | Indoor and outdoor glycol chiller packages |
| VE / G / Temptender | Temperature control units | Portable temperature control units |
| G300 / T300 | Temperature control units | Mid-size temperature control units |
| Regal | Temperature control units | Temperature control unit series |
| MZC (OACS "D" models) | Central chillers | Dual-zone outdoor chillers on multizone control |
HOW TO READ A MODEL NUMBER
What Each Part of the String Tells You
A full model number is built from the series prefix above followed by digits and, on many series, a suffix letter or two. Read left to right, the pieces generally answer three separate questions: which product line the unit belongs to (the prefix), how much capacity it carries (the digits that follow), and how it's configured (a suffix or code indicating single- versus dual-zone, or air- versus water-cooled condensing, where that option exists for the series).
The exact digit-and-suffix convention differs from series to series rather than following one universal pattern across the whole product line, which is exactly why this page points you to the series prefix first rather than trying to teach one decoder ring for every Advantage model. Once you know the series - say, OACS for an outdoor air-cooled central chiller, or BG for an outdoor glycol package - the remaining digits on that specific series' spec sheet tell you the capacity and configuration directly.
This is also why we don't recommend guessing at an exact part number from tonnage alone. Two series can offer overlapping capacity ranges with different standard features, footprints or condenser options built in, so the right model comes from confirming the full requirement - not just matching a number.
Fastest Path to the Right Model
- Have an old part number? Send it to us directly for confirmation
- Starting fresh? Use the Chiller Selection Guide first
- Know your product line but not capacity? Tell us the series and your heat load
- Unsure which series fits? Describe the application and we'll place it
