Micro-Mini Air-CooledPanel-Mounted Air Conditioners

The Micro-Mini Air-Cooled Panel-Mounted Air Conditioners deliver reliable, efficient cooling for sensitive electrical components in compact industrial enclosures. These units employ a closed-loop cooling system that isolates the internal component compartment from ambient air, preventing warm or contaminated outside air from invading the dehumidified sensitive equipment area and ensuring consistent temperature control where it matters most.

All blower motors are UL/CSA Recognized and equipped with automatic-reset thermal overload protection and double-sealed or double-shielded precision ball bearings rated to operate continuously from 14F (-10C) to 158F (70C). The motors utilize special permanent lubricants formulated to maintain performance across an exceptionally broad temperature range of -20F (-29C) to 250F (121C), guaranteeing reliable operation in extreme climates. CFC-free R134a refrigerant provides environmentally responsible cooling while meeting modern regulatory standards. A multi-layer corrugated aluminum filter with a one-piece aluminum frame keeps internal components clean and protected, with replacement filters readily available through Kooltronic's online spare parts service.

The units feature a Compressor Short Cycle Protector that safeguards against premature compressor wear by preventing restarts within several minutes of shutdown or following power interruptions, significantly extending compressor life in installations subject to solar gain or fluctuating thermal loads. A programmable thermostat enables precise temperature management, while an integrated temperature alarm with a thermostat-mounted sensor signals when preset limits are exceeded, allowing user-configured local or remote warning devices to trigger alerts. All units maintain NEMA 12 Rating compliance through full gasket seals for leak-proof installation and are UL/CUL Listed, meeting the highest standards for safety and performance in demanding industrial applications.
