Hammond DTS3661C230N3LG 25,353 BTU/h 230V NEMA 3R Outdoor Air Conditioner

The DTS3661C230N3LG is the higher-output 230 V light gray model in this outdoor family, rated at 25,353 BTU/h (7,424 W) at +95/+95°F (+35/+35°C). Its manufacturer description lists it as a NEMA 3R unit, and it side-mounts on large control enclosures where panel builders and facilities teams need maximum heat removal from a single closed-loop cooler.

The unit is designed for side mounting on any enclosure surface where high capacity system cooling is required. Closed loop cooling recirculates clean enclosure air without ever mixing it with contaminated ambient air, and the layout 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, and the unit runs filterless. The exterior case is galvanized sheet steel finished in RAL7035 light gray; an ANSI 61 gray version is available by replacing LG with GY in the part number.

Electrically, DTS3661C230N3LG is rated 230 V 50/60 Hz with an operating range of 207-253V, power consumption of 3678W, running current of 16.06A and a starting current of 32A, connected via terminal block. It circulates 1266 CFM internally and 728 CFM externally (unrestricted), uses 450 g of R134a refrigerant, and its thermostat is adjustable from +77 to +113°F (+25 to +45°C) with a factory setting of +95°F (+35°C). It operates in ambient air from +25°F (-4°C) to +131°F (+55°C) at a noise level of 81 dB(A).

Overall size is 57.2 in x 15.8 in x 16.1 in (1,453 mm x 401 mm x 409 mm) H x W x D, and the unit weight is 234.8 lbs/106.5 kg. Gasket, mounting kit and a template for the enclosure cutout and drilling are included, along with a condensate drain hose and clamp; a built-in condensate evaporator handles condensate discharge. The series carries UL, cUL and CE approvals, complies with IP56 and NEMA 3R, 4, 4X, and this part is listed as RoHS and REACH compliant.
