About Calienté LLC

Founded in 2001, Calienté delivers advanced thermal solutions that help customers operate more efficiently, reliably, and cost-effectively in demanding environments. The company began by developing innovative heating technologies for the telecommunications industry, enabling reduced energy consumption and system costs while improving performance in outdoor and mission-critical installations. That early focus on engineering excellence and system efficiency laid the groundwork for Calienté’s growth into multiple high-performance markets.

Today, Calienté serves customers across transportation and electrification, defense and military training, telecommunications and outdoor electronics, medical devices, and industrial packaging. Across each market, the company applies the same core philosophy: solving thermal challenges through smarter design and better engineering.

Engineered for Performance

Calienté’s core product portfolio centers on custom flexible pad heaters and integrated thermal solutions. In transportation and electric vehicle applications, Calienté supports battery pack thermal management, cabin and fluid heating, and defogging and de-icing systems for cameras, sensors, and aircraft.

In defense and military training environments, the company supplies thermal targets and platform heating solutions used in live-fire, simulation, and readiness applications. Telecommunications, medical, and industrial customers rely on Calienté for enclosure heating and cooling, battery warming, and precise temperature control in regulated, outdoor, and mission-critical settings.

  • “From the beginning, our mindset has been about creating value through better engineering and smarter system design. When we solve a thermal challenge the right way, our customers see it in reliability, efficiency, and total cost of ownership.”
