Thermal Edge enclosure air conditioners cross to the Pfannenberg DTS series for side mount and the DTT series for top mount. The tables below cover the CS, NE, HC and TM series. Read the two capacity columns carefully, because they are measured on different bases.

Read the Thermal Edge curve correctly
Thermal Edge performance curves are plotted against return air temperature, not enclosure temperature. A curve reading shows the BTU/hr with return air leaving the air conditioner at 95°F, which is not the same measurement as capacity at 95°F ambient with a 95°F enclosure. The true 95/95 figure is lower than the curve number. For that reason the crosses below are made against the published 95/95 capacity in the first column, and the curve column is shown for reference only.

Pfannenberg DTS part numbers carry a voltage code, so a family name such as DTS 31X1 covers the 115, 230 and 460V builds. Where a 95/95 figure is shown as two or three numbers, they are the 115 / 230 / 460V values in that order. Send the voltage and we return the full orderable part number.

The Pfannenberg DTT top mount range runs from the DTT 6101 at 1,785 BTU/hr published to the DTT 6801 at 14,000 BTU/hr. The DTT 6601 and DTT 6801 are 460V. Final sizing is confirmed against the heat load on the quote.

Compare capacity at 95°F/95°F, not the nameplate
Enclosure air conditioner ratings are not published at a single standard condition, so nameplate BTU/hr numbers across brands are not directly comparable. The honest comparison is capacity at 95°F ambient and 95°F enclosure temperature, read off the manufacturer's performance curve. A unit sold as 3,900 BTU/hr can deliver 3,400 BTU/hr at the 95/95 point. Every table on this page shows both numbers where the curve is published.
Four things have to line up before a substitution is valid:
- Capacity at the rating point. Match 95/95 performance, not marketing BTU.
- Voltage. 115, 230 or 460V must match the nameplate.
- Enclosure rating. NEMA Type 12, 3R, 4 or 4X on the air conditioner must match the enclosure environment.
- Mounting cutout. A capacity cross is not a cutout cross. Pfannenberg adapter plates cover specific retrofits; otherwise send the cutout dimensions with the model number and we confirm the mounting approach on the quote.
Also check where the cold air supply sits relative to the hot air return. Several competitor designs place them within 2 to 6 inches of each other, which lets cold discharge short-cycle straight back into the return and cuts effective cooling. Pfannenberg DTS units separate supply and return across the full height of the unit.
Common questions
What is the Pfannenberg equivalent of the Thermal Edge NE040?
The Pfannenberg DTS 31X1, the 4,000 BTU/hr class side mount delivering 4,100 at 115V and 4,500 at 230V at the 95F/95F point. The NE040 publishes 4,000 BTU/hr at 95/95, so the two match at the rating point.
What is the Pfannenberg equivalent of the Thermal Edge HC121?
The Pfannenberg DTS 32X5, which publishes 13,000 BTU/hr and delivers 11,000 to 12,000 at the 95F/95F point depending on voltage. The HC121 publishes 12,000 at 95/95. Both run 115, 230 or 460V.
Are Thermal Edge performance curves measured at 95F/95F?
No. Thermal Edge curves are plotted against return air temperature rather than enclosure temperature, so a curve reading shows BTU/hr with return air leaving the unit at 95F. That is a different measurement from capacity at 95F ambient with a 95F enclosure, and the true 95/95 figure is lower than the curve number. Size the replacement against the published 95/95 capacity, which is the first capacity column on this page.
What do the digits in a Thermal Edge model number mean?
The trailing xx is the UL type: 12 is Type 12, 04 is Type 4, 4X is Type 4X, and 4XL4 is Type 4X mill finish. The yy pair is voltage: 12 is 115 VAC, 23 is 230 VAC, 48 is 460 VAC. S48 models are the 460V harsh environment builds of the NE series.
