Duct heaters
Medium power duct heaters, with finned stainless steel heaters,
Type 9NF

Main applications

These medium duct heaters are mainly used in air duct, upstream vents, for heating industrial premises, in closed hot air circuit (recirculating air) or open circuit, with a mini air speed of 2m/s.

They are also used for drying, for heat treatment, dehydration, or cooking, in industrial processes.

They can be used on square or rectangular ducts. They consist of finned stainless steel heating elements, mounted on a stainless steel flange. Their installation in existing pipes requests cutting a 140x110mm rectangular hole, and drill 8

holes for 6mm dia. screws. The electrical connections are made in an IP65 aluminum housing. These devices are equipped with a 3 pole manual reset failsafe limiter.

 

Main features

Assembly: The finned tubes are oriented at 45 ° from the axis of the mounting bracket, thereby it is possible positioning the duct heater along or perpendicular to the conduit upon available spacing.

Ducts minimum sizes:

170mm heating elements references: 200 x 170 mm

320mm heating elements references: 350 x170mm

420mm heating elements references: 450 x 170mm

Duct opening: 140x110mm rectangular hole, plus 8 holes for dia.6mm screws (or equivalent size).

High limit thermostat: 3 poles, failsafe, manual reset, capillary thermostat, calibrated at 120°C (other values on request). Bulb mounted inside a waterproof pocket.

Connection box: in gray epoxy paint aluminum housing, IP65, 160 x 124 x 92mm, fitted with two M25, PA66 cable glands.

Minimum air velocity: ≥ 2m / s

Mounting bracket: 304 stainless steel, 150 x 235mm, 1.2 mm thick, with 8 holes for M6 screws (undrilled version on request).

IP65sealing between the heating elements, connection box and bracket

Heating elements: 3 or 6, non-removable, finned heaters, surface load 3.5W/cm ², 304L stainless steel, with internal connection on M4 screw terminals. The power of each element is 250 watts in 170mm, 500W in 320mm and 700W in 420mm (Other features, see page 8)

Voltage: 230V, 50/60Hz (110-120V on request).Wiring is possible in 230V single phase, or in 400V three-phase with neutral.

Power, surface load, air flow:

See, for information, in the technical section at the end of this catalog, the temperature charts recorded on standard models. However, it is up to the integrator to perform the appropriate checks of flow and temperatures reached in the application, and insure that they comply with the local regulations and safety standards.
