Description
These U shape sheathed heaters, designed for professional OEM are crimped on a light stainless steel flange, and are easy to integrate through metal wall. They have an exceptional insulation resistance and outstanding humidity resistance. They are designed for heating of air by natural convection or fans

Main Features
Heating elements material: 10mm dia. 304L stainless steel sheath. Optional: SS 201, 316, 321, or Incolloy 800. Connection: M4 stainless steel terminals screws with stainless steel M4 nuts and stainless washer, ceramic bead output.

Insulation resistance: > 3 GOhms (new), and > 1 GOhms (after following climatic test):
1000 hours at 100°C followed by 1000 hours at 60°C and 95% relative humidity, followed by 90 cycles of one hour from -20°C to +70°C, followed by 240 hours at -30°C.

Dielectric strength: > 1800 volts, 0.2mA (100% tested in production) and after climatic tests carried out by sampling.

Bracket: Crimped, 304 stainless steel, 1.2 mm thickness, with 4 M4 threaded holes, distances 65mm and 20mm.

Surface load:
For safe use, we recommend a maximum surface load of 1.2 W/cm² (7.8 W/in²) for applications in natural convection (heating element surface temperature ~ 300°C), and 3 W/cm² (19.5 W/in²) for applications in forced convection (heating element surface temperature ~ 300°C for an air velocity ~ 2.5m/s).

See P11 of section 2 of this catalog tables providing surface temperatures and air temperature vs load with and without fans
Voltage: 230V. Other values ​
Tolerances on power: +5/-10%
Options: Other surface load, other lengths, metal or plastic junction box, thermostat control with housing, special brackets with one or more heating elements.
