Electric Heater Advantages - Neptronic

1 The Neptronic Electric Heater is manufactured using the most advanced technologies available. Total automation fromdesign to production using integrated CAD/CAM systems not only assures maximum efficiency, but also prevents er-rors in plans and specification most advanced CNC technology for sheet metal fabrication is used in manu-facturing the heaters. All these factors are key to offering standard features that our competitors offer only as options,and allows us to respond in record time to your needs and to the most demanding Heater AdvantagesTypical Applications4 HVAC systemsVAV boxes4 Fan coil unitsTypical InstallationThe slip-in type Electric heaters are designed so that the entire frame can beinserted into the a slip-inheater permits the installation of the en-tire ventilation duct system before the heaters become available. Slip-InFlangedFlanged heaters are designed so thatthe Heater is an integral part of the ductwork.

2 The Heater frame is attached tomatching duct flanges. Standard 1"( ) flanges on the Heater frameare used to attach it to the duct. Round CollarRound collar Electric heaters are availablefor installation on round duct systems witha standard diameter of 6" to 24" (152mmto 609mm). They are provided with onemale and one female adapter for ease Networkable Electric Duct Heaters4 Patented EAS Electronic Air Flow Sensors (US 7,012,223) 4 Unique interactive software 4Up to 40kW per sq. ft.

Insulation material, 1" ( )thick is installed between the panel and the hot area toprevent condensation on electrical certain cases it may be more convenient to install thecontrol panel remotely from the Heater or in a separateroom. A remote control panel can be supplied 1 ( )All Neptronic heaters are designed and approved for zero clearance tocombustible material. Zero clearance construction means that there isno restriction on the distance between combustible materials and thesection of the duct housing the Heater , or the Heater itself.
