Rittal Air Conditioner Cross Reference

Rittal enclosure air conditioners cross to the Pfannenberg DTS series for side mount, the DTT series for top mount, and the DTI series for internal and recessed mount. The tables below cover Blue e+, Top Therm Blue e and internal mount models, compared at the 95°F/95°F rating point, with the Pfannenberg adapter plate part numbers that make specific retrofits bolt over the existing cutout.

Rittal side mount to Pfannenberg cross reference

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.

Adapter plates for Rittal retrofits

These Pfannenberg adapter plates cover the existing Rittal mounting cutout, so the replacement bolts over the opening instead of requiring new panel work. The SK 3328 and SK 3329 take both plates as a pair. We confirm the plate and unit pairing on the quote.

Rittal top mount to Pfannenberg cross reference

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.

Rittal internal and recessed mount to Pfannenberg DTI

Rittal internal mount and recessed units cross to the Pfannenberg DTI partially recessed series. All DTI units are 230 or 460V, NEMA Type 12. Adapter plate P/N 18380000043 covers the SK 3366 opening. Send the cutout dimensions with the model number and we confirm the mounting 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:

1. Capacity at the rating point. Match 95/95 performance, not marketing BTU.
2. Voltage. 115, 230 or 460V must match the nameplate.
3. Enclosure rating. NEMA Type 12, 3R, 4 or 4X on the air conditioner must match the enclosure environment.
4. 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 Rittal SK 3304?

The Pfannenberg DTS 31X1. The SK 3304 publishes 4,299 BTU/hr and delivers 4,265 at the 95F/95F point; the DTS 31X1 publishes 4,000 and delivers 4,100 at 115V and 4,500 at 230V. Pfannenberg adapter plate P/N 18380000041 covers the existing SK 3304 cutout for a bolt-over retrofit.

Do adapter plates exist to replace a Rittal air conditioner with a Pfannenberg?

Yes. P/N 18380000036 covers the SK 3303, P/N 18380000041 covers the SK 3304 and SK 3305, P/N 18380000043 covers the SK 3366 internal mount, and the SK 3328 and SK 3329 use P/N 18380000028 and P/N 18380000044 together as a pair. The plate lets the Pfannenberg unit mount over the existing opening.

What is the Pfannenberg equivalent of a Rittal Blue e+ air conditioner?

Blue e+ models from the SK 3178 through the SK 3189 cross to the Pfannenberg DTS series by capacity at the 95F/95F point, from the DTS 3021/3031 up to the DTS 34X1C. Check the enclosure rating line: many Blue e+ listings carry NEMA 12R and 3R, while every DTS size carries Type 12, 3R, 4 and 4X across the range.

Can Pfannenberg replace a Rittal internal mount or recessed air conditioner?

Yes, with the DTI series, which runs from the DTI 6201 C at 3,410 BTU/hr to the DTI 6801 at 13,640 BTU/hr at the 95F/95F point in 230 or 460V. Adapter plate P/N 18380000043 covers the SK 3366 opening. Send the cutout dimensions with the model number and we confirm the mounting on the quote.
