VariTrane® Fan-Powered Terminal Units


VariTrane® Fan-Powered Terminal Units

VariTrane® variable-air-volume (VAV) units lead the industry in quality and reliability and are designed to meet the specific needs of today’s applications. VariTrane fan-powered terminal units reduce energy use and operating cost with Electronically Commutated Motor (ECM) and modulating airflow control algorithms. This generation of VariTrane units builds upon history and expands the products into the most complete VAV offering in the industry.

Parallel fan-powered units offer energy savings due to intermittent fan control. The fan energizes only in heating mode when space needs heat. When energized, the fan can be controlled for constant-speed or variable-speed operation. Additional energy savings are obtained by using warm plenum air for free reheat. Motor heat is never wasted in parallel units. They are an excellent choice when minimal zone heating is needed.

Series fan-powered units have fans that are always energized in occupied mode. When energized, the fan can be controlled for constant-speed or variable-speed operation. They are common in applications such as conference rooms, cafeterias, etc., that desire higher supply airflow rates at all conditions.
