A new popular choice for us in custom AHU design is a fan array with EC Motors and fans. This technology has come a long way.  This is now our favorite alternative for in field unit replacements.

Each array features simplified power and control connections. Single point panel features an integral disconnect, individual  motor protection, and control terminals. These terminals are arranged for single speed, enable, and alarm contacts for Building Automation System interface.
