HEXONIC INC. Announces Heat Exchanger Selection Support for Data Center CDU Applications

GAFFNEY, S.C. / ACCESS Newswire / October 28, 2026 / HEXONIC INC. announces its technical support offering for heat exchanger selection in data center coolant distribution unit applications. The company manufactures heat exchangers and supports equipment selection based on operating conditions, thermal capacity and installation needs, including the requirements of liquid cooling systems serving artificial intelligence and high-performance computing workloads.

The offering combines equipment options with application-specific selection support. Hexonic's product range includes gasketed plate and frame, brazed plate, and shell and tube heat exchangers, alongside solutions tailored to particular installations. Its CDU Heat Exchangers | HEXONIC application offering addresses the thermal interface between the IT coolant circuit and the facility cooling circuit.

In liquid-to-liquid coolant distribution units, known as CDUs, the heat exchanger transfers heat between these circuits without mixing their fluids. This separation allows the IT loop and facility water loop to maintain different pressures, temperatures and fluid quality. It also helps protect server cooling equipment from differences in water chemistry and operating pressure.

"Heat exchanger selection for CDU applications depends on thermal capacity, temperatures, flow rates, pressure losses and coolant compatibility," said a company spokesperson. "These conditions define the requirements for heat transfer between the IT coolant circuit and the facility water loop."

The company's selection support addresses the operating conditions that determine exchanger performance rather than rated capacity alone. Relevant factors include supply and return temperatures on both sides, maximum operating pressure, allowable pressure drop and fluid compatibility. A smaller temperature approach can require a larger heat transfer surface, while excessive pressure drop increases pumping demand and can restrict coolant flow.

Compact plate heat exchangers provide a large heat transfer surface within a small footprint, making them suitable for CDU installations where equipment space is constrained. Selection also accounts for water quality, because fouling can reduce thermal performance and increase flow resistance. Filtration, material selection and access for maintenance form part of the installation considerations described in the company's application scope.

The support relates to the full cooling path. In direct-to-chip systems, coolant absorbs heat through cold plates attached to processors and returns to the CDU at a higher temperature. After heat transfers through the exchanger, facility water carries it toward cooling or heat recovery equipment. The exchanger must accommodate the operating conditions of both circuits.

Normal and peak loads, part-load operation and changes in computing demand are additional considerations. Maintenance access affects inspection, cleaning and replacement, while planned increases in rack power affect capacity requirements. Temperature control also remains relevant: coolant below the surrounding air's dew point can cause moisture to form on equipment.

Hexonic's application support places heat exchanger selection within the coordinated operation of cold plates, CDUs, controls and facility cooling infrastructure. Under specified operating conditions, appropriately selected exchangers support heat transfer while limiting pressure losses and maintaining separation between the coolant circuits.
