Hammond DTS3145A115LG 6,142 BTU 115V NEMA 12 Side-Mount Air Conditioner

The DTS3145A115LG is a side-mount indoor enclosure air conditioner for 115 V 60 Hz circuits, rated at 6,142 BTU (1,800 W) and described by the manufacturer as a 5-7,000 BTU/H light gray unit. It maintains an enclosure's NEMA 12 rating, giving panel builders and plant maintenance teams a closed-loop way to cool mid-size control cabinets from a common 115 V supply.

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.

DTS3145A115LG is rated 115 V 60 Hz with a range of operation of 103-127 V, power consumption of 1224 W, running current of 10.64 A and starting current of 48 A, connected by terminal block. It holds a 650 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.
