A new class of
heat exchanger

Phasic 500 kW heat exchanger core, printed as a single piece of metal

Your flow. Your temperatures. Your pressures.
One piece of metal, printed to match.

The most important part of your CDU is the one you didn't design.

Air can't keep up with rack power, and your customers want density you can't ship. The limit is your heat exchanger: stamped, brazed, and in every competitor's cabinet.

What if that limit became your edge?

5–15%
of your bill of materials: 100%
of your thermal ceiling

Modern data centers need top-performing CDUs.
Performance starts with Phasic.^‡

+20%^†

Rack Density

More compute in the same room. It's that simple.

The core does the same duty in at least 25% less volume; the best build to date uses half. Spend the freed space on a smaller cabinet, or on more capacity in the one you already ship.

$30M^*

a year

20 MW more sellable compute

20% more density at a 100 MW site is 20 MW of added capacity. At wholesale colocation rates that is roughly $30M a year from the same footprint and the same building.

$350K^*

a year per degree

Every degree cuts chiller runtime

A core designed for approach temperature instead of volume allows warmer facility water and more free-cooling hours. ASHRAE puts each degree at 1 to 3% of cooling energy. At 100 MW and PUE 1.4, the 1% case is about $350K a year.

* Figures assume a 100 MW site, wholesale colocation rates and PUE 1.4.
† A smaller core removes what forces a bigger enclosure or a second unit.
‡ Each part is designed to your duty point; competitors specify from the same five suppliers.

It all comes down to geometry.

Shapes that can’t be drawn by hand or stamped by a press.

AI designs it

Our AI is trained on more than 80,000 CFD simulations. It takes your duty point and returns printable CAD in about a minute, generating novel geometries that a thermal engineer, a CFD analyst and a CAD designer would spend months converging on.

Every passage tuned to your duty point

Ports, ducts and channels change shape together until the part fits your pressure-drop ceiling and meets the target you put first: approach temperature or size. Our AI tunes the hot and cold sides separately, which a stamped plate cannot do.

Printed as one piece of metal

No plate pack. No braze. No gaskets. One printed part, in stainless or aluminium, with no joint anywhere for a coolant to find.

The printed exchanger in bare metal, one piece with four ports.

A 500kW build, measured.

Not a catalog part. A Phasic core built for approach temperature, against a conventional brazed plate at the same duty and about the same volume. Set a different target and these numbers move.
