Hammond DTI6401A460LG 6820 BTU/h 460V Semi-Recessed Indoor Air Conditioner

The DTI6401A460LG is a semi-recessed indoor air conditioner rated at 6820 BTU/h (2000 Watts) of cooling capacity at +95/+95°F (+35/+35°C). It is a mid-range model of the DTI Series for 460 V, 60 Hz power, with a deeper 120 mm internal section than the smaller units. The DTI Series is designed for recessed mounting on any enclosure surface where high capacity system cooling is required, making it a fit for control panel builders, OEM machine builders and facilities teams protecting heat-generating electrical equipment.

Closed loop cooling recirculates clean enclosure air without ever mixing it with contaminated ambient air, and the airflow path keeps maximum clearance between the warm inlet and cold outlet to reduce hot spots. The condenser uses 3 mm fin spacing for protection against strongly contaminated and aggressive ambient air. The unit uses R134a refrigerant, a multi-controller with energy saving mode integrated by default, a hot gas bypass valve against evaporator freeze-up, a built-in condensate evaporator, self-diagnostics on startup and a provision for a door contact to power down when the enclosure door is opened.

Overall dimensions are 60.51 in x 19.09 in x 8.58 in by the part listing; the ordering table gives H 60.51 in (1537 mm), W 19.09 in (485 mm) and overall depth 10.94 in (278 mm), split into 6.22 in (158 mm) external and 4.72 in (120 mm) internal depth. The enclosure cutout is K 59.45 in (1510 mm) by L 17.72 in (450 mm). Electrically it is rated 460 V ±10%, 60 Hz, with 911 W power consumption and a 7.7 A starting current, connected through a spring-type terminal block with plug.

A gasket, mounting kit and template for the cutout and drilling are included, along with a condensate drain hose and clamp. The unit maintains the enclosure's NEMA 12 rating, is rated IP 54, carries cUL and CE marks, and is finished in RAL 7035 powder-coated galvanized sheet steel. It is RoHS and REACH compliant.
