Open Coil Duct Heaters


The open coil elements are the most popular in the industry, suitable for most standard HVAC ducted systems. The biggest advantage of these elements is the excellent heat dissipation capacity with heating capacities ranging from 0.5 to 1000 kW.
Features of the Open coil elements
• Minimal pressure drop
• Fast response time
• Up to 40 kW per sq.ft.
• Quick delivery
The grade C open coil elements type is made up of nickel, chrome and iron. Neptronic® offers, for applications in humid environments, NiCr 80 (grade A) elements which do not contain any iron.

Tubular Duct Heaters


The Standard and Finned tubular type offers an excellent mechanical resistance, suited for demanding environments. These elements are less sensitive to humid and dusty environments but offer a slower response time.
Features of the standard and finned tubular elements
• Up to 13 kW per sq.ft. (Standard) and Up to 15 Kw per sq.ft. (Finned).
• Heating elements not in direct contact with air.
• Element of U or W shape.
Tubular elements are made of Incoloy 800 (Nickel alloy) tube with a diameter of 3/8” (9.5mm) which contains a heating coil in magnesium oxide powder. Finned tubular elements have aluminum fins installed on the tube to allow a higher heat dissipation capacity.
