The CUVN40504 is a vertical cooling unit manufactured by Hoffman Enclosures, Inc. It provides a cooling capacity of 4050W and operates on an AC voltage of 400V at 50 Hz. The unit is constructed from mild steel and features an IP54 protection degree, corresponding to NEMA Type 12 standards. This component is designed for thermal management within electrical enclosures.
Verify the specific operating voltage requirements (400V AC) against your facility's power supply before procurement. Confirm that the IP54/NEMA 12 rating meets the environmental protection needs of the installation site. Ensure the mounting dimensions are compatible with the target enclosure model. Check standard lead times as availability may vary by distributor.
Select this unit when a cooling capacity of approximately 4050W is required for vertical mounting applications. Consider the 400V power requirement during system design. Evaluate the IP54 rating against the specific dust and water exposure levels of the deployment environment to ensure adequate protection for internal components.
This component belongs to the Hoffman climate control product line, which includes various cooling units and heaters. These products are engineered to maintain optimal temperatures within electrical and electronic enclosures, safeguarding sensitive equipment from overheating and environmental degradation in industrial and commercial applications.
Consult official manufacturer documentation for verified substitute part numbers. Ensure any replacement maintains equivalent cooling capacity, voltage specifications, and physical mounting dimensions to guarantee compatibility with existing enclosure systems.
