Thermal Energy Storage
PCM Thermal Boards
Phase change material boards that absorb and release heat during peak load cycles — entirely passively, with no pump and no moving parts. Ideal for pulsed-power satellite payloads and edge AI systems with intermittent duty cycles.
Technology
Peak Load Absorption
During high-power operation the PCM absorbs excess heat by melting — keeping component temperatures stable without active cooling or power budget impact.
Passive Heat Release
Between active cycles the stored heat is released as the PCM solidifies, ready for the next peak load event with no external intervention.
No Power, No Moving Parts
Entirely passive — no pump, no fan, no electronics. Ideal for space environments where power budget and reliability are critical.
Space-Grade Construction
Materials selected for vacuum compatibility, outgassing compliance, and long mission life — consistent with EW JET's space-grade manufacturing standards.
Applications
Pulsed-Power Payloads
Absorb heat during short bursts of high-power transmission or sensing without active cooling or power budget impact.
GEO / LEO Satellites
Buffer thermal loads across orbit-eclipse cycles — passive, reliable, with no maintenance access needed for 15+ year missions.
Edge AI Systems
Smooth intermittent compute spikes in compact, fanless enclosures where passive thermal management is required.
Generations
PCM2
Second-generation PCM thermal storage board for passive peak-load buffering in satellite payloads. Precision-machined aluminum enclosure with integrated phase change material.
PCM3
Third-generation PCM thermal board with refined capacity and geometry over PCM2. Optimized for high-pulsed-power GEO/LEO payloads requiring extended thermal buffering.
Performance Data
PCM3 test data available — PCM2 in preparation
130 W charge/discharge test results for PCM3 are published on the PCM3 product page. PCM2 data is being compiled.
