The Stratus line of compact enclosure air conditioners are closed-loop cooling systems designed for use in harsh environments, for wash-down requirements and when heavy dust and debris or airborne chemicals are present. Available in NEMA 4, 4X and 12 ratings, the TA20 series air conditioners provide a contaminant-free environment and optimal cooling under higher ambient temperatures. Designed to fit 7- or 8-in-deep enclosures, the TA20-0 frame size 1,000-Btu/H units are available in 120-Vac and 48-Vdc voltages; for 10-in-deep enclosures with smooth, flat sides, TA20-1 2,000 Btu/H units are available in 120- and 230-Vac voltages.
