£3,754.80
The nVent HOFFMAN CUVN40504 is a high-performance vertical-mounted enclosure cooling unit designed to provide reliable thermal management for large industrial electrical cabinets, automation systems and control enclosures. As part of the nVent HOFFMAN CUVN cooling unit series, it delivers efficient cooling performance while helping protect sensitive electrical components from excessive heat build-up.
The CUVN40504 uses an external vertical mounting configuration to maximise usable enclosure space while providing powerful cooling performance. Smart energy management technology helps reduce energy consumption, while the self-cleaning condenser coil eliminates the need for a standard air filter and reduces routine maintenance requirements.
With a 4050 W cooling capacity, 400 V AC three-phase supply and IP54 / TYPE 12 protection rating, the CUVN40504 is suitable for demanding industrial applications requiring dependable enclosure climate control.
The nVent HOFFMAN CUVN40504 maintains stable enclosure temperatures by removing heat generated by PLCs, drives, power supplies and other high-performance electrical components. Effective cooling helps improve equipment reliability and reduces the risk of thermal-related failures.
Designed for industrial automation environments, the CUVN series combines powerful cooling performance with practical installation benefits including external mounting, smart energy management and low-maintenance operation through its self-cleaning condenser system.
