HVAC – Boilers & Chillers

HVAC boilers and chillers are important components for building maintenance and construction. The chillers are responsible to provide air conditioning in buildings and boilers are imperative to keep buildings warm. Fuji Electric’s AC Drives are utilized in the commercial HVAC market to work with individual fans and fan arrays along with our HPAQ drives are used for individual fans. In conjunction to the AC Drives running the HVAC system, Fuji Electric’s instrumentation products are used to measure the steam and pressure generated by the boiler or chiller.

AC Drives

Fuji Electric’s AC Drives are utilized in the commercial HVAC market to work with individual fans and fan arrays. Our Mini and AC drives are highly used for fan arrays, along with our HPAQ drives are used for individual fans. Applications within HVAC require a very reliable product that can be networked or follow an analog signal from the building automation system. This network reduces any additional wiring to be able to transfer information back to the building. Fuji Electric is one of the few major manufacturers utilizing our own power components internally, providing consistency and compatibility for future upgrades and reliability, with an industry leading 3-year warranty.

Instrumentation & Control

In conjunction to the AC Drives running the HVAC system, Fuji Electric’s instrumentation products are used to measure the steam and pressure generated by the boiler or chiller. Ultrasonic flow meters can also measure the energy efficiency by calculating K-factor. Gas analyzers are utilized to monitor the combustion of natural gas to create the steam in a boiler. Once the steam has been made the differential pressure transmitter can measure the steam that is generated by the boiler along with measuring the flow of the water. In addition, Fuji Electric’s ultrasonic or differential pressure transmitters are used to measure the flow of water from cold water into the boiler.
