Hammond DTS3265A115N3LG 9-12000 BTU/H 115V Light Gray Type 3R/4 AC Unit

The DTS3265A115N3LG is a 9-12000 BTU/H side-mount outdoor air conditioner, the high-capacity light gray model in this DTS range with a Type 3R, 4 rating. It is built for large control and electrical enclosures where substantial heat must be removed through a closed loop, serving OEMs, integrators and facilities teams.

Clean enclosure air is recirculated in a closed loop and never mixes with contaminated ambient air, while the wide spacing between warm inlet and cold outlet reduces hot spots. The condenser has 3 mm fin spacing for protection against strongly contaminated and aggressive ambient air, so the unit runs filterless. It uses R134a refrigerant with a 1200 g charge, a hot gas bypass valve against evaporator freeze-up, and a built-in condensate evaporator. The exterior case is galvanized sheet steel finished in RAL7035 Light Gray; an ANSI 61 Gray version is ordered by replacing LG with GY in the part number.

As the 115 V 60 Hz version, the DTS3265A115N3LG operates across 103-127 V, consumes 1850 W, draws 16.9 A running and 20 A at start, and connects through a terminal block. Rated cooling capacity is 12472 BTU (3657 W) at +95/+95F (+35/+35C), and the noise level is <70 dB(A). Listed dimensions are A 53.00 in (1346 mm), B 16.00 in (406 mm) and C 14.40 in (366 mm); unit weight is 150 lbs/ 68 kg. The drawing shows overall dimensions of 53.13 in (1349.61 mm) by 16.00 in (406.40 mm) by 14.38 in (365.21 mm).

The unit mounts on the side of any enclosure surface, and the gasket, mounting kit, cutout and drilling template, condensate drain hose and clamp are included. Its thermostat is accessible from inside the enclosure and adjusts from +77 to +113°F (+25 to +45°C), factory set to +95°F/+35°C. Startup self-diagnostics, LED fault indication, EMI/RFI suppression meeting CE and a door contact provision for power-down when the door opens round out the controls. Standards are UL, cUL and CE with IP56; this part carries a Type 3R, 4 rating and is REACH and RoHS compliant.
