£2,204.00
The nVent HOFFMAN BLU45BXUB is a high-performance air/water indoor heat exchanger designed to provide reliable thermal management for electrical enclosures and industrial control cabinets. As part of the nVent HOFFMAN BLU series, it removes excess heat from enclosure interiors using chilled water or liquid cooling circuits to maintain safe operating temperatures for sensitive electrical equipment.
The BLU45BXUB combines efficient cooling performance with a compact enclosure-mounted design, making it suitable for demanding industrial applications where conventional air cooling is unsuitable. Its galvanised steel construction provides durability, while its UL-recognised design supports use in industrial control and automation installations.
With a cooling capacity of 4500 W, a 230 V AC single-phase supply and dimensions of 1148 × 398 × 163 mm, the nVent HOFFMAN BLU45BXUB delivers dependable enclosure cooling for large electrical cabinets and automation systems.
The nVent HOFFMAN BLU45BXUB air/water heat exchanger provides efficient cooling where enclosure temperature control is critical. By transferring heat through a liquid cooling circuit, it allows electrical cabinets to operate reliably in environments where ambient air cooling is not sufficient.
Designed for industrial automation and electrical control applications, the BLU45BXUB helps protect valuable components from overheating while supporting long service life and dependable system performance.
