Hammond DTS3481C460N4SS 20,901 BTU/h 460V Stainless Type 4X Enclosure Cooler

For 460 V plants that need a stainless, Type 4X rated cooling unit, the DTS3481C460N4SS provides 20,901 BTU/h (6,120 W) at +95/+95°F (+35/+35°C) behind a brushed 304 stainless steel cover. It side-mounts on the enclosure and runs at 4.06 A, giving OEM engineers and maintenance teams a high-capacity closed-loop option for harsh, corrosive or washdown environments.

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, DTS3481C460N4SS is rated 460 V 50/60 Hz with an operating range of 414-506V, power consumption of 2431W, running current of 4.06A and a starting current of 7A, connected via terminal block. It circulates 1330 CFM internally and 674 CFM externally (unrestricted), uses 650 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 210.1 lbs/95.3 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.
