NVENT HOFFMAN CUVN59504 Cooling unit 5950W

Why Choose the nVent HOFFMAN CUVN59504 5950W Cooling Unit?

The nVent HOFFMAN CUVN59504 is a high-performance vertical enclosure cooling unit designed to control temperatures inside industrial electrical and automation enclosures. With a nominal cooling capacity of 5950 W at L35/L35 conditions, it provides powerful thermal management for installations with substantial internal heat loads.

Designed for external vertical mounting, the CUVN59504 maximises usable space inside the enclosure while maintaining a closed cooling circuit between the enclosure and surrounding environment. The unit measures 1405 mm high × 554 mm wide × 404 mm deep and is manufactured from powder-coated galvanised steel with an RAL 7035 finish.

The CUVN59504 incorporates a self-cleaning condenser coil, eliminating the need for a conventional air filter and reducing routine maintenance requirements. It also features a condensation dissipator and digital display, uses R134a refrigerant, and provides IP54 / Type 12 protection for demanding indoor industrial enclosure applications.

High-Capacity Thermal Management for Industrial Enclosures

Electrical and automation components generate heat during operation, and excessive enclosure temperatures can reduce component life, cause unexpected shutdowns and compromise system reliability. The nVent HOFFMAN CUVN59504 uses a closed-loop refrigeration system to remove heat from inside the enclosure while maintaining separation between internal enclosure air and the surrounding environment.

With 5950 W of cooling capacity at L35/L35, the CUVN59504 is particularly suited to high-heat-load control systems. Its external vertical mounting configuration preserves valuable internal enclosure space, while the self-cleaning condenser, digital control and condensate management features help simplify operation and maintenance in industrial environments.

Typical Applications

• Industrial electrical control enclosures.
• PLC and automation cabinets.
• Variable-speed drive and motor control enclosures.
• Industrial power electronics.
• Manufacturing and production machinery.
• Process control installations.
• Electrical distribution and control systems.
• High-heat-load enclosures requiring closed-loop cooling.
