What Belilove does

Belilove Company - Engineers (BCE), founded in 1952 and headquartered in Hayward, California, is a privately held specialty manufacturer of custom electric thermal systems and vacuum feedthrough devices. The company designs and builds heating elements (cartridge, tubular, band, strip, ceramic, cable, immersion, and flexible heaters), vacuum-compatible heated chucks and thermal platens for semiconductor wafer processing, circulation heaters for clean liquids and gases, and proprietary products such as the HEM Sealed Heater (a NASA ASTM E595-compliant sealed cartridge heater for space launch propellant heating) and the SMART FLOW liquid heater with a patented fin design. BCE also manufactures custom vacuum feedthroughs that pass electrical, thermocouple, and fluid connections through vacuum chamber walls using proprietary ceramic and epoxy seals, with leak rates to 10^-9 to 10^-10 atm·cc/sec.

BCE serves industrial customers through a direct, quote-based sales model backed by online product builder tools and application engineering support, with a primary focus on semiconductor OEMs, aerospace and defense contractors (enabled by ITAR registration), analytical instrumentation manufacturers, pharmaceutical and biotech firms, petrochemical operators, and research institutions. The company is ISO 9001:2015 certified (renewed for 2026/2027) and ITAR registered, and operates from a single California manufacturing facility with a global customer reach. Revenue is generated primarily through custom hardware sales and supporting engineering services, with stock heaters sourced from a distribution partnership with Backer Hotwatt supplementing the custom-engineered core.
