Cabinet AC

Cabinet AC is designed for industrial electrical cabinets with IP55 protection, wide temperature range (-40°C~+55°C), vibration resistance, and continuous duty operation. Regular home AC cannot meet these industrial requirements.

A box-type transformer AC is designed for outdoor compact substations (European/American type transformer boxes, RMU boxes) where transformers and LV/HV equipment concentrate heat and can trip in summer. Haocheng HCK 3000–7500W cabinet AC units apply directly: IP55 dust/rain protection, -40~55°C range, wall/top mounting and 48V DC option — keeping transformers stable, extending equipment life and reducing outage losses.

A prefab cabin (integrated prefab substation, energy-storage cabin, containerized equipment room) is larger than a single cabinet and generates more concentrated heat, so it needs higher cooling capacity and more even airflow. Haocheng 5000W/7500W models suit prefab cabin cooling with top/side mounting and RS485 remote monitoring, providing precise climate control for primary/secondary devices and storage batteries in dusty, rainy, hot or cold environments.

Industrial AC broadly covers refrigeration equipment for industrial environments (workshops, plants, equipment rooms). Cabinet AC is the sub-category focused on electrical enclosures: closed-loop compression cooling, IP55 protection, -40~55°C operation and long service life to protect electrical components. Haocheng's full cabinet AC series belongs to this high-end segment of industrial AC — for control panels, distribution cabinets, telecom cabinets and more.

Common options: ①Filter fans — air exchange only, no real cooling, useless in high heat; ②Heat exchangers/heat pipes — passive, fail when the temperature difference is small; ③Thermoelectric (TEC) — no compressor, silent, but low capacity, for small cabinets only; ④Vapor-compression (cabinet AC) — active cooling with precise control, ideal for high heat loads and outdoor high-temperature sites. Haocheng uses compression cooling with smart control, balancing effect and energy use.

Based on cabinet size, internal heat load, and ambient temperature. Generally: small cabinets (<1m³) → 3000W, medium (1-2m³) → 5000W, large (>2m³) → 7500W. Our engineers can provide precise sizing calculations.
