How to Decode an Applied Comfort PTAC Model Number
Applied Comfort model numbers look cryptic, but most series follow a similar pattern, with a few differences noted below. Once you can read one, you can check a quote, spot an ordering error, or tell us exactly what you need over the phone.
The pattern
Take a 16 Series example: 16EE09K34E7N.
| Part | Example | What it means |
|---|---|---|
| Series | 16 | The chassis family, which sets the sleeve size |
| Heat type | E | E = electric resistance, W = hydronic (hot water or steam), H = heat pump |
| Design version | E | In the 16 and DM Series, E marks the current R-454B design |
| Cooling size | 09 | 09 = 9,000, 12 = 12,000, 15 = 15,000 BTU/h |
| Voltage | K | K = 230/208V, L = 115V, N = 208V, R = 277V |
| Heater | 34 | Electric heat in kW: 25 = 2.5 kW, 34 = 3.4 kW, 50 = 5.0 kW, 00 = none |
| Controls | E | E = electronic, S = standard mechanical |
| Cord | 7 | 6, 7, 8 = 15, 20, 30 amp LCDI cord; 1, 2, 3 = standard cord; 0 = hard-wired |
| Fresh air | N | M = mechanical door, N = none, P = power damper |
Series by series
- DM Series: DMQE or DHE first. DMQ is the electric heat air conditioner, DHE the heat pump. Example: DMQE09K34E7.
- K Series: KEE, KWE, or KHE. Here the third letter is the controls (E = electronic), not a design version. Example: KEE12K25_6 is a 12,000 BTU, 230/208V unit with 2.5 kW heat and a 15 amp LCDI cord.
- EA Series: EAEE for electric heat, EAWE for hydronic. Example: EAEE12K34_7.
- 16 Series: 16EE for electric heat, 16WE for hydronic.
An underscore in a catalog model number stands for a position that varies, usually the controls letter.
Three checks before you order
- Voltage letter matches the building. A K unit will not run on a 277V circuit, and an R unit will not run on 208V.
- Heater matches the circuit. Larger heaters need larger circuits. A 5.0 kW heater at 230V needs a 30 amp circuit and plug, which is why those models end in 8.
- Cord matches the receptacle. If the old unit was hard-wired, order a 0 or a permanently connected model.
Older model numbers
Earlier Applied Comfort units used other design letters. The EA's previous generation was the EAEC, and earlier DM units were the DMQC and DHPC. Those used R-410A. Current units with the E design letter use R-454B but fit the same sleeves.
Send us the number
If you have the old unit's model number, from any brand, send it with your request. We translate it into the current Applied Comfort equivalent. See all Applied Comfort PTACs.
Send the model and serial number from the old unit's nameplate, or the inside sleeve dimensions, through the contact form or call 800-866-1210. We confirm the fit before anything ships.
