The DTT6601B460LG is a three-phase 400/460 V top-mount air conditioner for industrial enclosures in the DTT 7000-14000 BTU/H indoor series. It suits OEM machine builders, panel shops and plant engineers who need to take a large heat load out of a NEMA 12 control enclosure from the roof, where side mounting space is not available. The Hammond spec sheet rates it at 11,000 BTU/h (3200 Watts) at +95/+95F (+35/+35C); the part page describes it as a 10700BTU unit.
The unit's technical data sheet gives cooling capacity at A35/A35 of 3000 W at 50 Hz and 3200 W at 60 Hz, and at A50/A35 of 2000 W and 2250 W. On 400 V/50 Hz it draws 1700 W with 3.16 A nominal current and 8.9 A starting current; on 460 V/60 Hz the figures are 2100 W, 4.5 A and 9.9 A. It uses 1250 g of R134a refrigerant and moves 1970/2180 m³/h of external air and 1420/1530 m³/h of internal air (50/60 Hz). Noise level is 62 dB(A) at 1 m.
Closed loop cooling keeps enclosure air separate from contaminated ambient air, and the patented condensate management system with condensate evaporation keeps water out of the cabinet. The thermostat is factory set at +35°C (+95°F) and adjustable +77 to +113F; a failure indication triggers above +50°C (+122°F) enclosure temperature. Self-diagnostics, LED fault indication, a hot gas bypass valve and a door contact input (no external voltage) are standard.
Overall size is 19.09 in (485 mm) H x 31.30 in (795 mm) W x 22.64 in (575 mm) D, with a 27.24 x 15.43 in (692 x 392 mm) cutout. The unit installs vertically, needs at least 200 mm clearance to walls and other units, and weighs 75 kg per the data sheet (shipping weight 170 lbs / 77.11 kg). Construction is steel and plastic, galvanized and electrostatically powder coated in RAL 7035. The DTT6601B460LG maintains NEMA 12, is IP 54 toward the enclosure and IP 34 toward the environment, and carries UR, cUR and CE.
