Electric coils are an HVAC accessory that in certain applications utilize electricity to reheat conditioned supply air for an occupied space. There are two types of electric coils provided on Price's terminals and fan coils: duct heaters and terminal unit heaters. Both achieve the same goal of providing supplemental reheat to the occupied space but differ in their construction and configuration.

Chilled beam technology is often separated into two categories: active and passive. As we explored in a previous blog post, active chilled beams take in primary air from an air handler, which is then pressurized and released through a series of nozzles. Passive chilled beams, however, do not have any supply air ducted to them and operate utilizing natural convection. This energy-efficient cooling device is often coupled with other air systems such as underfloor air, displacement ventilation and active chilled beams.
