Hammond DTS3285A115N4SS 9-12000 BTU/H 115V Stainless Type 4X AC Unit

The DTS3285A115N4SS is a 9-12000 BTU/H side-mounting air conditioner with a 304 stainless steel exterior and a Type 4X rating, the highest-capacity stainless model in this DTS range. It is meant for large enclosures in corrosive or outdoor locations where a panel needs substantial closed-loop cooling without ambient air ever entering the cabinet.

Enclosure air stays in a closed loop, separated from contaminated ambient air, with maximum clearance between the warm inlet and cold outlet to limit hot spots. A condenser with 3 mm fin spacing gives strong protection against contaminated and aggressive ambient air and allows filterless operation. Refrigeration uses R134a with a 1200 g charge and a hot gas bypass valve that prevents evaporator freeze-up, and condensate is handled by a built-in condensate evaporator. The exterior is 304 stainless steel with a Polish #4 finish.

As the 115 V 60 Hz version, the DTS3285A115N4SS 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 4X rating and is REACH and RoHS compliant.
