The DTT6801B460LG is the highest-capacity model in the DTT 7000-14000 BTU/H top-mount indoor air conditioner series. Rated 14,500 BTU/h (4250 Watts) at +95/+95F (+35/+35C) on a 400/460 V three-phase supply, it is built for OEMs, integrators and plant engineers cooling large, heavily loaded NEMA 12 enclosures from the roof when side mounting is not an option. The part page describes it as AIR CONDIT 14000BTU 460V LG.
According to the unit's technical data, cooling capacity at A35/A35 is 4000 W at 50 Hz and 4250 W at 60 Hz, and at A50/A35 it is 3260 W and 3495 W. Power consumption is 1601 W at 400 V/50 Hz and 1989 W at 460 V/60 Hz, with nominal current of 4.6 A / 4.5 A and starting current of 17.1 A / 19.5 A. The refrigerant is R134a (1250 g charge). External air volume is 1970/2180 m³/h and internal air volume 1420/1530 m³/h (50/60 Hz), with a 62 dB(A) noise level at 1 m.
- Closed loop cooling; enclosure air never mixes with contaminated ambient air
- Patented condensate management with built-in condensate evaporation
- Thermostat factory set +35°C (+95°F), adjustable +77…+113F; failure indication above +50°C (+122°F)
- Hot gas bypass valve, self-diagnostics on startup, LED fault indication, door contact input
The DTT6801B460LG measures 19.09 in (485 mm) H x 31.30 in (795 mm) W, with depth listed as 22.64 in (575 mm) on the part page and 22.60 in (574 mm) in the ordering table, and fits a 27.24 x 15.43 in (692 x 392 mm) cutout. It installs vertically with at least 200 mm clearance, weighs 77 kg per the data sheet and ships at 175 lbs (79.38 kg). The steel and plastic unit is galvanized and powder coated in RAL 7035, maintains NEMA 12, is IP 54 toward the enclosure and IP 34 toward the environment, and carries UR, cUR and CE.
Ideal For
- High heat load NEMA 12 enclosures on 400/460 V three-phase power
