At JAYE-HEATER, we engineer our heaters for maximum service life. By following these essential practices, you can ensure your silicone rubber heaters operate efficiently for years to come, reducing downtime and replacement costs.
1. Foundation of Longevity: Correct Installation
A perfect heater can fail prematurely if installed incorrectly. This is the most critical phase for ensuring a long service life.
- Ensure a Clean, Smooth Surface: The surface the heater is mounted to must be clean, free of debris, and smooth. Any particles trapped between the heater and the surface create hot spots, which degrade the heater and the adhesive over time. Use isopropyl alcohol for cleaning.
- Achieve Full Surface Contact: The heater must be in complete, intimate contact with the surface it is heating. Use even pressure during application to eliminate air gaps. For adhesive-backed heaters, a J-roller is highly recommended to ensure a strong, uniform bond.
- Follow Proper Mechanical Fixing Guidelines: If using clamps or straps, ensure the pressure is evenly distributed. Avoid over-tightening, which can damage the heater's internal elements or create points of excessive mechanical stress. Do not puncture the heater with screws or rivets directly through the active heating area.
2. Operational Excellence: The Key to Sustained Performance
How you operate the heater directly impacts its functional lifespan.
- Respect the Power Density Limits: Every JAYE-HEATER is designed with a specific watt density (watts per square inch). Never exceed this rating. Overpowering the heater is a primary cause of rapid failure, leading to burnt elements and degraded silicone.
- Implement Proper Thermal Management: While silicone rubber heaters distribute heat evenly, the heated surface must dissipate that heat effectively. If the system has poor thermal dissipation, heat will build up, causing the heater to overheat and fail prematurely. In cyclic applications, this is especially critical.
- Use a Compatible, Calibrated Controller: Always use a temperature controller (like a thermostat or PID) that is properly matched to your heater and integrated temperature sensor (e.g., thermocouple). This prevents the heater from running continuously and exceeding safe temperatures. Ensure the sensor is placed correctly to provide accurate feedback.
3. Proactive Care and Handling: Simple Steps for Maximum Life
Daily handling and environmental factors play a significant role.
- Avoid Sharp Bends and Abrasion: While flexible, silicone rubber heaters should not be creased or folded sharply, especially over a tight radius. This can damage the internal heating element. Also, protect the heater from abrasion and sharp edges in the application environment.
- Mind the Environment: Be aware of your operating environment. Exposure to certain chemicals, oils, or solvents can degrade the silicone rubber over time. If your application involves such exposures, inquire about our specialty-grade silicone or other material options like fiberglass.
- Perform Visual Inspections: Periodically, and when the system is powered down and cool, inspect the heater for any signs of damage
4. Common Pitfalls to Avoid (The "Don'ts")
- DON'T cut or modify a standard heater to fit an application. This can damage the element and create electrical hazards. Always order a custom-shaped heater from the manufacturer.
- DON'T use the heater in a "free-air" (unattached) configuration unless it was specifically designed for it. Most silicone rubber heaters require being mounted to a surface to dissipate heat properly.
- DON'T ignore the lead attachments. The flexible leads are a critical connection point. Avoid bending them sharply right at the heater's edge and ensure they are mechanically restrained to prevent strain.
