Made of 304-2B stainless steel, the patented Integrity Series Air Conditioners are designed specifically for NEMA 4/4X enclosures which require wash-down, are subject to outdoor storm conditions or other harsh environments. With the addition of the Integrity Series 21, the line is now available in five heights from 21 to 59 inches and capacities ranging from 3,000 to 10,000 BTU/H.

"Kooltronic is always striving to bring new and unique products to the marketplace," noted Richard Wenstrom Kooltronic's director of sales and marketing. "Development of the Integrity Series 21 was based on customer interest in a compact NEMA 4/4X air conditioner," he added. With the addition of the 12 inch wide Integrity Series 21, we now have a NEMA 4/4X air conditioner to fit almost any enclosure.

Available in 115 VAC and 230 VAC (50 or 60 Hz), the Integrity Series 21 is UL/CUL Recognized and uses CFC-free R134a refrigerant. It's designed for easy installation, utilizing the innovative M-Seal Mounting System which seals the unit to the enclosure with just three screws.
