Hammond DTT6401B230LG 7160 BTU/h 230V Top-Mount Enclosure Air Conditioner

The DTT6401B230LG is the 230 V high-capacity model in the DTT 4000-7000 BTU/H top-mount indoor air conditioner series, rated 7160 BTU/h (2100 Watts) at +95/+95F (+35/+35C). It serves panel builders, integrators and plant engineering teams who need to remove a large heat load from an electrical enclosure but cannot mount a unit on the side of the cabinet. The part description lists it as a 7100BTU unit.

It runs on 230 V (+/- 10%) at 50/60 Hz, consuming 1049/1275 W with running current of 6.2 / 7 A and starting current of 16.8 / 20 A. The electrical connection is a terminal block with plug. A hot gas bypass valve prevents evaporator freeze up while minimizing heavy inrush currents on large BTU/H units like this one, and a door contact provision lets the unit power down when the enclosure door is opened.

Closed loop cooling ensures clean enclosure air is recirculated without mixing with contaminated ambient air. The patented condensate management system prevents condensate from penetrating the enclosure, backed by a built-in condensate evaporator. The unit uses R134a refrigerant and high capacity fans for continuous circulation, runs self-diagnostics on startup and indicates faults with an LED. Its thermostat adjusts +77 to +113F (+25 to +45C) from inside the enclosure.

The DTT6401B230LG measures 17.13 in (435 mm) H x 23.43 in (595 mm) W x 19.49 in (495 mm) D, with a 19.29 x 15.50 in (490 x 394 mm) cutout, and ships at 106 lbs (48.08 kg). Included are the gasket, mounting kit, cutout and drilling template, condensate drain hose and clamp; mounting uses tool-less sash fasteners. It is finished in RAL 7035 powder-coated galvanized sheet steel, maintains NEMA 12, is rated IP 54 and carries UR, cUR and CE approvals.
