Hammond DTS3145A460LG 6,995 BTU 460V Side-Mount Indoor Enclosure Cooler

The DTS3145A460LG supplies 6,995 BTU (2,050 W) of side-mounted enclosure cooling from 460 V 50/60 Hz power at only 1.88 A running current. It maintains the NEMA 12 rating of indoor control enclosures, making it a practical choice for electricians and panel shops that want to feed cabinet cooling from existing 460 V industrial distribution.

Designed for side mounting on any enclosure surface, the unit uses closed loop cooling so clean enclosure air is recirculated without ever mixing with contaminated ambient air, and it keeps maximum clearance between the warm inlet and cold outlet to reduce hot spots. The condenser has 3 mm fin spacing for protection against strongly contaminated and aggressive ambient air. The exterior case is galvanized sheet steel in RAL7035 light gray; ANSI 61 gray is available by replacing LG with GY.

DTS3145A460LG is rated 460 V 50/60 Hz with a range of operation of 360-506 V, power consumption of 1496 W, running current of 1.88 A and starting current of 16 A, connected by terminal block. It holds a 825 g R134a charge and provides 341 CFM and 706 CFM of circulation (both listed as internal on the spec sheet) (unrestricted). A hot gas bypass valve prevents evaporator freeze up, and the thermostat is accessible from inside the enclosure with a factory setting of +95°F (+35°C). Ambient operating range is +59°F (+15°C) to +131°F (+55°C) at a noise level below 70 dB(A).

Series ordering dimensions are A 36.65 in (931 mm), B 11.89 in (302 mm) and C 14.40 in (366 mm). Unit weight is 108 lbs/49 kg and shipping weight is 108 lbs (48.99 kg). Gasket, mounting kit and template for the enclosure cutout and drilling are included, along with a condensate drain hose and clamp. The series maintains the enclosure's NEMA 12 rating (IP 54) and carries UL, cUL and CE approvals; this part is listed as RoHS and REACH compliant.
