Why Choose Warren Technology?

Warren Technology has been a leading name in electric heating equipment for more than six decades. Known for their precision-engineered products, Warren designs both standard unitary slip-in heaters and custom duct heaters that meet a wide range of electric heating and ventilation specifications.

Since its founding in 1957, Warren has pushed the boundaries of HVAC innovation. They were among the first American manufacturers to merge flexible manufacturing with computer-aided design (CAD), a move that pioneered today's computer-integrated manufacturing (CIM). This forward-thinking approach allows Warren to quickly prototype, test, and produce high-quality products that evolve with industry needs.

With a deep commitment to technological advancement, Warren holds multiple U.S. and international patents and continues to develop new solutions that improve indoor comfort, energy efficiency, and air quality.

Leading the Way in Indoor Comfort and Air Quality

Warren’s expertise extends beyond heating. As concerns around indoor air quality (IAQ) and workplace wellness grow, Warren has introduced innovative solutions like the Valid Air® high-performance diffuser and the Leopard Intellivent® personal VAV diffuser. These patented systems help eliminate stagnant air pockets, reduce HVAC noise, and support healthier, more productive indoor environments.

Solutions like Valid Air® and Leopard Intellivent® are engineered to:

  • Improve air circulation.
  • Enhance personal comfort by maintaining consistent room temperatures.
  • Address issues associated with Sick Building Syndrome (SBS), including allergies and respiratory concerns.
  • Promote higher energy efficiency and reduce operational costs.

By improving the indoor environment, building owners can boost employee satisfaction and productivity, an important advantage in today's competitive markets.
