Electric duct heaters specification
A. Supply and install electric heaters as manufactured by NEP (Neptronic) or
approved equal, model DF, slip-in or flanged or round collar type, CSA-C
and CSA-US certified according to CSA standard C22.2 No. 155 and UL
1996. Electric heaters shall be manufactured and approved for zero
clearance for all combustible materials.
B. Heater frames shall be made of galvanized or stainless steel, assembled
with rivets — no welding allowed. The control panel shall have pre-punched
flanges for easy field installation and rounded corners therefore preventing
sharp edges.
C. Heating elements shall be open coil, grade C nickel chrome alloy
(standard) or open coil, grade A (NiCr80) nickel chrome alloy, no traces of
iron or tubular type, made of incoloy 800 (Nickel alloy) tube with a
diameter of 3/8"(9.5mm) containing a heating coil in magnesium oxide
powder or finned tubular type, made of incoloy 800 (Nickel alloy) tube with
a diameter of 3/8"(9.5mm) containing a heating coil in magnesium oxide
powder, supported by ceramic bushings in an enclosed frame design.
D. Electric heaters shall be provided with an ON/OFF or a SSR modulating
first stage and fixed additional stages.
E. All heaters have: magnetic contactors (standard) or mercury contactors or
silent type contactors; automatic thermal cutouts (standard) or manual
thermal cutouts (when required by code); fixed or adjustable airflow
switch, transformer with secondary fuse, internal wiring for the number of
stages indicated, disconnects etc.
F. All the controls shall be integrated and pre-wired within a NEMA-1 control
panel which will include a removable, hinged door to provide easy access
or NEMA-12 control panel which will include a removable, hinged door to
provide easy access or NEMA-4 certified control panel or NEMA-4X
certified control panel.
G. If scheduled, modulating electric heaters shall be supplied with an
electronic sensor on each side of the heater to measure the temperature
and the airflow, and a Neptronic HEC controller to adjust the output
temperature in accordance with the measured parameters. The Neptronic
HEC controller shall stop the electric heater when there is no airflow.
