| 1.1 |  Defense Thermal Challenges

Defense platforms operate under constraints that commercial systems rarely face. Thermal management solutions must be compact, lightweight, and reliable across extreme temperature ranges, shock and vibration loads, and corrosive environments. Space is always limited -- whether inside a naval vessel, an armored vehicle, or a mobile command post. Failure is not an option.

| 1.2 |  Growing Thermal Loads

Modern defense systems are generating more heat than ever. High-power radar arrays, directed-energy weapons, advanced electronic warfare systems, and dense computing clusters for intelligence processing all produce significant thermal loads. As these systems become more capable, the heat they generate grows -- often faster than the platforms designed to house them.

| 2.1 |  Why Conventional Heat Exchangers Fall Short

Standard commercial heat exchangers are designed for controlled environments with stable operating conditions. Defense applications demand performance across wide temperature swings, salt spray exposure, high-G maneuvers, and extended service intervals. They also demand compactness -- a heat exchanger for a naval cooling system may need to deliver the same thermal capacity as a commercial unit in half the volume and a third of the weight.

| 2.2 |  Applications Across the Battlespace

Compact, high-performance heat exchangers enable thermal management for naval propulsion cooling, shipboard electronics, mobile radar systems, forward-operating base cooling, and satellite ground station thermal regulation. In each case, the heat exchanger must be designed for the specific platform -- its fluids, temperatures, physical envelope, and operational profile.

| 3.1 |  Phasic and NATO DIANA

Phasic Energy's acceptance into NATO's DIANA program validates the defense relevance of our heat exchanger technology. We design thermal solutions for the most demanding environments -- delivering high performance in compact, reliable packages that meet the unique requirements of defense platforms. The same design principles that drive performance in data center cooling apply to defense: maximize heat transfer, minimize pressure drop, and fit within the tightest possible envelope.
