CryoR is a research-driven cryogenic engineering company based in Israel, serving clients worldwide with advanced thermal management solutions. We specialize in the design and development of compact, high-reliability cryocoolers for aerospace, defense, medical, industrial machines, and scientific instrumentation. Founded by Dr. Nir Tzabar, CryoR brings over two decades of expertise in Joule-Thomson (JT) and closed-cycle cryocooler systems. Our technologies are engineered for zero-vibration, low-maintenance, and mission-critical applications, with proven performance in infrared sensing, and advanced research environments. Unlike mass-market suppliers, CryoR offers a flexible, project-based approach, enabling highly customized thermal solutions tailored to each client’s specific technical and operational requirements. Our systems are currently in use by research institutions, and OEMs. Core Capabilities • Turnkey integration support for complex scientific and industrial platforms • Compact JT cryocoolers (open-cycle and closed-cycle) • Multi-head configurations powered by a single compressor • Thermal system modeling, performance simulation, and optimization • Fast cool-down designs with a focus on reliability and long-term operation
