SlimKool Series SP43 480 Volt 3-PhaseNEMA 4 or 4X Air Conditioners

The SlimKool Series SP43 is a 480-volt, 3-phase air conditioning unit engineered for precise temperature control in electrical enclosures within demanding industrial environments. Designed in a compact, slim profile that minimizes installation footprint, this unit delivers closed-loop cooling where the interior airflow system is completely isolated from ambient air, preventing unconditioned air from infiltrating the sensitive component compartment and ensuring consistent dehumidification and protection of critical electronics.

The SP43 features an advanced refrigeration system using CFC-free R134a refrigerant and includes a built-in condensate evaporator that eliminates the need for manual condensate drainage under normal operating conditions, with overflow provisions and included drain fittings for added safety. The epoxy-coated condenser and evaporator coils provide extended corrosion resistance capable of withstanding 1000 hours of salt spray testing per ASTM B 117, while internal corrosion protection on the refrigeration system's brazed joints offers additional safeguarding in harsh environments. A compressor short cycle protector defends against frequent start cycles that could shorten equipment life, particularly valuable in installations subject to solar gain or fluctuating heat loads. Condenser impeller cycling control optimizes energy efficiency by modulating cooling capacity in response to actual thermal demand.

Control and monitoring capabilities include a programmable thermostat for precise temperature management, a programmable temperature alarm for early alert conditions, and phase sequence/phase loss detection with under-voltage monitoring to protect against electrical anomalies. The heavy-duty steel shell with ANSI 61 gray polyester powder coating is fully gasketed to maintain NEMA Type 4 enclosure ratings, with stainless steel cabinet construction available for NEMA 4X applications in corrosive or chemically aggressive environments. All units include a multi-layer aluminum filter to maintain internal cleanliness, with replacements readily available. The SlimKool Series SP43 is UL/CUL Listed for safety and reliability.
