Access Series DSP23Ultra-Slim, Door or Panel-Mount Air Conditioner

The Access Series DSP23 Ultra-Slim is a compact door or panel-mount air conditioner engineered to maintain precise temperature control within industrial electrical enclosures while occupying minimal installation space. This unit combines powerful cooling performance with advanced protective features designed to safeguard sensitive electronic components in demanding environments.

All models maintain NEMA 4 protection with an IPX6 rating (UL50), ensuring reliable operation in wet or corrosive locations. The unit features a heavy-duty steel shell with a powder-baked finish in ANSI 61 gray, with custom color options available upon request. The closed-loop cooling system isolates the enclosure interior airflow from ambient conditions, preventing unconditioned air from invading the cool, dehumidified component compartment. An integrated condensate evaporator eliminates the need for manual condensate draining under normal operating conditions, though an overflow drain fitting and hose are provided for use in high-humidity environments or situations with enclosure leaks. The condenser and evaporator coils are epoxy-coated to withstand 1000 hours of salt spray per ASTM B 117 testing, providing extended protection in corrosive settings.

The DSP23 Ultra-Slim incorporates intelligent control technology including a programmable thermostat for versatile temperature management, a programmable temperature alarm (available when heater option is not selected), and a compressor short cycle protector that extends compressor life by preventing rapid restart cycles caused by power interruptions or fluctuating heat loads. Condenser impeller cycling control optimizes energy efficiency by modulating fan speed. The unit uses CFC-free R134a refrigerant and includes a multi-layer aluminum grid filter to maintain internal cleanliness. Each model is UL/CUL Listed, ensuring compliance with recognized safety standards.
