4ULHX
Air-to-Liquid Heat Exchanger
Higher heat density is a major concern when electronics in 19” applications are upgraded. Conventional methods of in-rack forced air or air conditioning may not be enough to protect vital electronics from overheating with the rapid advancement of AI chips & GPUs.
Designed in a compact, 4U size to minimize space, our air-to-liquid heat exchanger can be installed and retrofitted into any 19” cabinet with at least 800 mm depth.
The Ruggedized version can meet the requirements of naval and land-based defense applications.
Our COTS air-to-liquid heat exchanger enables short lead time design, offering multiple levels of cooling performance, allowing users to achieve higher computing density in new racks and existing applications.
KEY FEATURES

Frequently Asked Questions
- What types of liquid can the 4U LHX use?
Water 100%, or PG mixtures up to 50% or EG mixtures up to 50%.
- Can the 4U LHX make the thermal load be lower or higher than 7.5 kW?
Yes, the 4U LHX can be configured to run in low energy, then the device can achieve low thermal load with low noise. If higher cooling is desired, 2 LHX units can be installed in one cabinet to achieve up to a 15 kW thermal load.
- Can the 4U LHX be integrated into non-nVent cabinets?
Yes, the 4U LHX is designed to be retrofittable into a 19” cabinet with a minimum depth of 800mm. (Internal and external dimensions in accordance with: IEC 60297-3-100, -101, IEEE 1101.1)
- Does nVent provide plumbing accessories?
Yes, nVent can provide plumbing accessories found on the user manual pages 27 and 28.
- What is the power input?
Power input is 100 ~ 240 VAC Power.
