Half Quartz Element (HQE)

Description

Half Quartz Infrared Heating Element (HQE)

A versatile infrared quartz heating element (200 – 500 W) providing an instant heat response for a variety of industrial process applications. These elements are particularly effective for manufacturing processes where a rapid heater response is required.

Available Wattage: 200 – 500 W

Size: 123.5 x 22.5 x 62.5 mm

Useful wavelength range: 1.5 – 8 microns

Average weight: 217 g

Heater Voltage: 230 V standard

Other Variations: voltages, wattages, lead length and terminations available on request

Average Operating Life: 10,000 hrs depending on conditions

Iron-chrome aluminium resistance wire

Recommended radiation distance from heater is 100 – 200 mm

Minimum recommended spacing between elements: 5 mm.

Supplied with 120 mm ceramic beaded power leads

Ensure temperature of the aluminium clad steel body does not exceed 500 °C (932 °F).

Element should always be mounted so the quartz glass tubes are horizontal.
