Seifert 42712001 KG 4271 SlimLine control cabinet air conditioner
This model provides 3,020 BTU at 95°F / 95°F and operates from 380/415 V at 50 Hz or 400/460 V at 60 Hz, three-phase. It supports external or recessed mounting with a powder-coated mild-steel housing and IP54 protection.
Low-Profile Cabinet Cooling with External or Recessed Mounting
The Seifert 42712001 KG 4271 SlimLine is a control cabinet air conditioner designed to remove heat from industrial electrical equipment. The listed rating is 3,020 BTU at 95°F / 95°F. The unit operates from 380/415 V at 50 Hz or 400/460 V at 60 Hz, three-phase, and its RAL 7035 gray, powder-coated mild-steel housing is designed for external or recessed mounting.
Its 5.71-inch depth limits how far the cooling unit projects from the enclosure, while external and recessed mounting options help designers work around panel-space constraints. A wide-ribbed aluminum condenser supports filter-free operation, reducing routine maintenance without adding disposable filter media.

⚠️ Verify Cooling Conditions, Voltage, and Cabinet Cutout
Cooling capacity is rated at specific internal and ambient temperatures. There is a second rating of 1,810 BTU at 95°F / 122°F, demonstrating how available output changes with operating conditions. Before ordering, calculate the enclosure heat load and confirm the available voltage, phase, frequency, fuse protection, mounting method, cutout dimensions, and condensate route.
This model is designed for indoor enclosure cooling within a listed operating range of 50°F - 131°F. Do not select the unit from the maximum BTU rating alone.
📋 Enclosure Cooling and Maintenance
The wide-ribbed aluminum condenser increases exposed surface area so the unit can operate without a disposable filter. This construction helps limit scheduled maintenance, but the condenser and airflow paths should still be inspected and cleaned whenever site conditions cause buildup.

📋 Basic Installation Overview
1. Size the Cooling Unit: Calculate the enclosure's internal heat load and account for the highest expected ambient temperature before confirming capacity.
2. Verify Electrical Service: Match the available voltage, phase, frequency, branch protection, starting current, and connection method to the specifications.
3. Prepare the Enclosure: Confirm the 38.58" H × 15.55" W × 5.71" D unit dimensions and Not specified cutout dimensions, then follow the product document when laying out the opening.
4. Mount and Manage Condensate: Install the unit using the specified external or recessed mounting method and provide the required condensate route without obstructing either air circuit.
5. Commission the System: Energize the unit, confirm fan and compressor operation, check the temperature setting, and verify that the enclosure maintains the required internal temperature.
Installation and electrical work should be completed by qualified personnel using the linked Seifert documentation and applicable codes.
