Hammond DTS3681C460N4SS 25,930 BTU/h 460V NEMA 4X Stainless Enclosure Cooler

At 25,930 BTU/h (7,593 W), the DTS3681C460N4SS is the top-capacity stainless model of this outdoor side-mount family, built for 460 V 50/60 Hz supplies. The brushed 304 stainless steel cover and NEMA 4X rating in its manufacturer description suit washdown areas and corrosive outdoor locations where OEM engineers must remove large heat loads from sealed control enclosures.

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 is a brushed 304 stainless steel cover.

Electrically, DTS3681C460N4SS is rated 460 V 50/60 Hz with an operating range of 414-506V, power consumption of 3060W, running current of 5.18A and a starting current of 10A, connected via terminal block. It circulates 1277 CFM internally and 813 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.
