R.W.FLAME: 62 DOE certified models

R.W.FLAME has 62 basic models certified to DOE as of 2026-11-03: 55 portable ACs (5,000 to 10,200 BTU/h SACC), 3 window ACs (6,200 to 8,100 BTU/h) and 4 dehumidifiers (24.83 to 49.86 pints/day under the 2019 DOE test). 49 are the same unit as models filed under other brands. How their efficiency compares with their DOE class is below.

Key findings

  • Highest certified cooling capacity among its portable ACs: R.W.FLAME A5410CE, R.W.FLAME NPH-10C/X1E, R.W.FLAME NPH-10CE and 1 more tie at 10,200 BTU/h SACC.
  • Most efficient for its class: R.W.FLAME OL-A018DD10N3BP/S, CEER 12, higher than 1,035 of the 1,044 single hose portable ACs certified to DOE.
  • Highest certified cooling capacity among its window ACs: R.W.FLAME 54091EWA0-8K-RW and R.W.FLAME 54091EWA1-8K-RW tie at 8,100 BTU/h.
  • Most efficient for its class: R.W.FLAME 54091EWA0-8K-RW, CEER 16.3, higher than 102 of the 105 in its DOE class (window ACs, 8,000 to 13,999 BTU/h).
  • Highest certified water removal among its dehumidifiers: R.W.FLAME D026W-50Pt3M at 49.86 pints/day.

A higher CEER means more cooling per watt. A higher IEF means more water removed per kWh.

Who makes R.W.FLAME portable ACs, window ACs and dehumidifiers?

DOE's database has no manufacturer field, so the evidence is whose model number each unit is filed under and which other brands file the same unit.

R.W.FLAME shares 49 units with 42 other brands. Its other 13 basic models are filed by R.W.FLAME alone. Brands it shares with, and how many units each:

R.W.FLAME units filed under one DOE basic model with other brands, 12 of 49. DOE data as of 2026-11-03.

How much do R.W.FLAME models cost to run?

While cooling, R.W.FLAME portable ACs draw about 696 to 1,291 W (certified SACC divided by CEER). That's 13¢ to 23¢ an hour, or $30.34 to $56.27 for 30 days at 8 hours a day. The lowest is R.W.FLAME AC7290-10K (5,500 BTU/h SACC, CEER 7.9) and the highest R.W.FLAME A5410CE (10,200 BTU/h SACC, CEER 7.9).

While cooling, R.W.FLAME window ACs draw about 460 to 610 W (DOE's listed power input). That's 8¢ to 11¢ an hour, or $20.05 to $26.59 for 30 days at 8 hours a day. The lowest is R.W.FLAME 54091EWA0-6K-RW (6,200 BTU/h, CEER 15.1) and the highest R.W.FLAME 54091EWA0-8K-RW (8,100 BTU/h, CEER 16.3).

Running nonstop at DOE's test conditions, the 4 R.W.FLAME dehumidifiers with both figures use 6.91 to 11.71 kWh a day. That's about $1.26 to $2.13 a day, or $37.65 to $63.79 for 30 days. The lowest is R.W.FLAME 75025EDE0-WHITE-EL (24.83 pints/day, IEF 1.7) and the highest R.W.FLAME 75026EDE0-WHITE-EL (49.74 pints/day, IEF 2.01).

Real use cycles on and off with the humidity, so the dehumidifier figures are the upper end for a day of nonstop running.

At 18.16¢ per kWh, the US average residential price for August 2026 (EIA Electric Power Monthly, table 5.6.A). Worked out from the certified figures.

Questions about R.W.FLAME

Is R.W.FLAME a good dehumidifier brand?
How its 4 dehumidifiers compare on efficiency with their DOE class is above. 4 of them are the same unit as another brand's model. We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.
Does R.W.FLAME make a 50 pint dehumidifier?
Yes, by the 2019 DOE test: 2 of its models certify 49.5 pints/day or more, led by R.W.FLAME D026W-50Pt3M at 49.86 pints/day. By DOE class: 1 in the up to 25 pints/day class and 3 in the 25 to 50 pints/day class. How the 2019 test changed pint ratings.
Which R.W.FLAME dehumidifier is the most efficient for its size?
R.W.FLAME D026W-50Pt3M, at IEF 2.2: higher than 293 of the 296 in its DOE class (portable dehumidifiers, 25 to 50 pints/day). At the other end is R.W.FLAME 75025EDE0-WHITE-EL, at IEF 1.7, higher than 94 of the 253 in its class.
Is R.W.FLAME the same as Antarctic Star?
For 49 units, yes: both file them under the same DOE basic model (A010L-8K, A011D2-10K, A011E-8K, A4208K-WHITE and 45 more). The other 13 R.W.FLAME basic models aren't filed by Antarctic Star.
