Hammond DTS3261A115N3LG 6,825 BTU/h 115V NEMA 3R/4 Outdoor Air Conditioner

The DTS3261A115N3LG is the larger-capacity 115 V outdoor model in this family, rated at 6,825 BTU/h (2,000 W) at +95/+95°F (+35/+35°C) and described by the manufacturer as a 7,500 BTU/H NEMA 3R light gray unit. It side-mounts on weather-exposed enclosures and moves 450 CFM on both internal and external air circuits for bigger heat loads.

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 exterior is NEMA 3R/4 galvanized sheet steel with a powdercoat finish in RAL7035 light gray; an ANSI 61 gray version is available by replacing LG with GY. An expansion valve prevents evaporator freeze up while minimizing heavy inrush currents.

DTS3261A115N3LG is rated 115 V 60 Hz with an operating range of 103-127 V, consumes 1680 W, and draws 11.6 A running and 53 A starting, wired through a terminal block. It carries a 700 g charge of R134a refrigerant, moves 450 CFM internally and 450 CFM externally (unrestricted), and uses a 150 g/m² filter mat. The thermostat, accessible from inside the enclosure, adjusts from +77 to +113°F (+25 to +45°C) with a factory setting of +95°F (+35°C). Rated ambient range is +32°F (0°C) to +131°F (+55°C), with a noise level of <73 dB(A).

Unit weight is 123 lbs (56 kg) and shipping weight is 141 lbs (63.96 kg). Gasket, mounting kit and template for the enclosure cutout and drilling are included, as are a condensate drain hose and clamp, and a built-in condensate evaporator handles condensate discharge. Self-diagnostics run on startup, faults are shown by LED, and a door contact provision allows power down when the enclosure door is opened. The series carries UL, cUL and CE approvals and complies with NEMA 3R, 4 and IP56. This part is listed as RoHS and REACH compliant.
