MENLO PARK, Calif. — Nagle Energy Solutions (NES) has announced plans to sell its bundled ventilation control system for commercial garages directly to building automation controls contractors, mechanical contractors, and electrical contractors throughout North America.
NES designs and manufactures its digital, demand control ventilation (DCV) solution for enclosed commercial garages which the company says reduces energy consumption by an average of 93 percent — while leaving the garage fans running continuously. Consequently, the bundled solution enables commercial property owners to convert an inefficient and often expensive operational process — ventilating the garage — into a source of energy savings.
NES digital controllers and peripherals are scalable and conform to several building management system (BMS) and energy management system (EMS) communication platforms, and they have the capability to monitor and report on energy consumption/savings. In addition, the NES system integrates a web server that enables building owners/managers to conduct system status checks and adjust operational parameters from their desktops, or from their laptops anywhere at any time.
The principal component of the NES product offering is the ventilation controller, which includes:
• The NES FG-20, which utilizes an EasyIO controller with a Sedona programming framework; and
• The NES TR25, NES TR50, and NES TR100, each of which incorporates a Tridium JACE controller with a Niagara programming framework.
The NES FG-20 controller is designed for customers desiring a stand-alone garage DCV system for small- to medium-sized commercial garages, but it can be scaled for use with the BACnet® and Modbus® communication protocols for additional functionality. It can be configured to control up to 25 devices, e.g., carbon monoxide (CO) sensors and variable frequency drives (VFDs), and it can control a single zone or multiple zones and multiple garage fan motors and VFDs.
The NES TR25, TR50, and TR100 are Internet accessible via any Internet browser, with an optional onboard display to facilitate commissioning, system adjustments, and troubleshooting. Like the NES FG20, they can control a single zone or multiple zones, as well as multiple garage fan motors and VFDs.
The NES TR25 is configurable to serve up to 25 devices when incorporating an energy monitoring capability and up to 50 devices without the energy monitoring capability. The NES TR50 is configurable to serve up to 50 devices with an energy monitoring capability and up to 100 devices without the energy monitoring capability. The NES TR100 is configurable to serve up to 100 devices with an energy monitoring capability and up to 200 devices without the energy monitoring capability.
NES bundles its controllers with Danfoss VFDs, NES gas sensors — CO and nitrogen dioxide (NO2) — and alarm components, all of which are “synced” to proprietary smart-control logic that detects and measures vehicle fumes in the garage and then modulates fan speeds to prevent CO levels from exceeding pre-determined set points. The result is greater operational efficiency and optimum energy savings.
