Seifert 43150001 KG 4315 ComPact enclosure air conditioner
This model provides L35L35 cooling capacity of 5,120 BTU/hr at 50 Hz or 5,560 BTU/hr at 60 Hz and operates from 230 V AC, 50/60 Hz. It supports external mounting with a powder-coated mild-steel housing and IP54 protection.
230 V ComPact Cooling for Medium-Heat-Load Enclosures
The Seifert 43150001 KG 4315 ComPact is an enclosure air conditioner designed to remove heat from industrial electrical equipment. The listed rating is L35L35 cooling capacity of 5,120 BTU/hr at 50 Hz or 5,560 BTU/hr at 60 Hz. The unit operates from 230 V AC, 50/60 Hz, and its RAL 7035 gray, powder-coated mild-steel housing is designed for external mounting.
This version of the KG 4315 supplies different rated capacities at 50 and 60 Hz, allowing it to serve 230 V cabinets across either frequency when the electrical installation matches the data sheet. The display and touchpad make operating status and temperature settings accessible, while filter-free condenser construction keeps routine maintenance straightforward.

⚠️ Verify Cooling Conditions, Voltage, and Cabinet Cutout
Cooling capacity is rated at specific internal and ambient temperatures. There is a second rating of 4,160 BTU/hr at 50 Hz or 4,500 BTU/hr at 60 Hz under L35L50 conditions, 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 surface-treated condenser and high fin separation allow the unit to operate without disposable filters. The result is a simpler maintenance routine, although the condenser, fans, drains, and airflow paths should still be inspected at intervals appropriate for the facility. The display shows cabinet temperature and operating status, while the touchpad provides access to the adjustable temperature controller.

📋 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 × 10.24" D unit dimensions and 36.22" x 13.19" cutout dimensions, then follow the product document when laying out the opening.
4. Mount and Manage Condensate: Install the unit using the specified external 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.
