Halogen/Wolfram Heater Installation, Operation, and Safety Information

Xuchang Infrared's halogen/tungsten heaters emit infrared energy primarily in the mid-wave and short-wave ranges. The energy is generated by tungsten filaments sealed within a quartz glass tube. All objects above 0 degrees emit infrared energy, providing a safe and effective non-contact heating method. However, all high-intensity heat sources require certain precautions during installation and operation. The following are safety instructions for using quartz halogen/tungsten filament short-wave heaters:

1.  The heater is designed to allow only horizontal operation, excluding clearly defined vertical operations. Metal clamps are recommended for installation at the cold ends of the heating tube.

Heaters should be installed by qualified personnel to ensure compliance with all relevant electrical safety standards.

Ensure the power source matches the heater's rated voltage. Additional voltage will reduce the operating lifespan of the heater.

When operating in cold environments (typically indoor temperatures), halogen/wolfram heaters will withstand currents over 10 times the normal operating current.

Ensure that insurance or other protective devices are correctly calibrated to handle this startup current.

6. The flat sealed portion of the heater (the flat glass section at both ends of the terminals) should not be exposed to temperatures exceeding 300 degrees Celsius. Temperatures above this value will cause gas leakage and reduce the operational lifespan of the heater.

7. The halogen/tungsten heater body is a sealed quartz glass tube. Like all glass products, this heater should be handled with care. Additional mechanical or physical force during operation and installation can break or damage the glass tube. Broken glass can pose a hazard to personnel or the heating process.

When handling the heater, gloves should be worn. Fingerprint oils can affect the optical performance of the glass tube and may reduce the heater's operational lifespan. When picking up the heater, grasp the ends of the heating tube, the cold end section, to avoid direct contact with the heated section. The gold plating should be avoided from coming into contact with hard objects and being rubbed.

9. The temperature of glass tubes may exceed 600 degrees Celsius. Like all high-temperature heat sources, it is necessary to carefully ensure that there are no potentially explosive gases that can ignite upon contact with the glass tubes in the air environment where the heater operates. In all cases, operators are responsible for ensuring that the heater is suitable for their specific application.

10. Halogen/Tungsten heaters are high-intensity infrared heaters. Caution must be exercised to ensure that no one comes into contact with the heater during operation, and it is always important to maintain a safe distance from the heater to avoid the risk of being burned by its infrared output.

11. Halogen heaters can produce intense white light, which may cause harm to human eyes. Caution must be exercised to ensure that personnel do not directly gaze at the heater during production. If necessary, a filter to reduce glare or protective eyewear should be provided. In such cases, appropriate warning signs must be in place to alert personnel to the danger.

For heating tube currents exceeding 8A (which can be directly started below 8A) and frequent startups, the control method of the heating tube must be adjusted. The specific method is as follows:

Heating tubes are controlled through a power regulator or a voltage regulator. When initiating the heating tube, the warming-up process is divided into two steps. First, set the heating tube to output warming-up power from 0 to 30% or below. Second, after the heating tube's power output reaches 30%, pause for 2 seconds, then continue to increase the pressure to the final set output ratio (e.g., 70%), completing the startup process. After the heating is complete, instead of reducing the power output to 0, maintain a low power output of 10-20%. This reduces the impact of startup current when restarted, thereby avoiding issues like board explosion due to excessive startup current. This adjustment can be made through a PLC.
