Integrity Series 38 NEMA 4/4XAir-Cooled Panel-Mounted Air Conditioners

The Integrity Series 38 NEMA 4/4X Air-Cooled Panel-Mounted Air Conditioner delivers dependable climate control for sensitive electronic enclosures in demanding industrial environments. This unit employs CFC-free R134a refrigerant with closed-loop cooling architecture that completely isolates the enclosure's interior airflow system from ambient conditions, preventing uncontrolled outside air from compromising the clean, dehumidified environment where your sensitive components operate. A multi-layer corrugated aluminum filter with one-piece aluminum frame protects internal parts from airborne contaminants at the point of air intake, with convenient online replacement filter ordering available through kooltronic.com/spareparts.

The unit features electronic thermostatic low temperature control that prevents over-cooling while optimizing energy efficiency, and head pressure control that minimizes compressor cycling and protects the evaporator coil from icing. For operations in chemically aggressive or salt-spray environments, a stainless steel shell option and internal corrosion protection coating--standard on all NEMA 4X models--provide enhanced durability. The internal coating applied to condenser brazed joints withstands 1000 hours of salt spray per ASTM B 117 testing, though severe environments such as wastewater treatment facilities may require additional consultation regarding long-term performance and warranty coverage.

Fully gasketed construction maintains NEMA 4/4X enclosure ratings per UL50, ensuring tight, leakproof performance in wet and corrosive locations. All units are UL/CUL Listed, meeting the stringent safety and performance standards required for mission-critical industrial applications.
