Silicone is used because of its high temperature resistance (Constant temperature up to 200°C (390°F), high thermal conductivity (~7 10-4W/cm.K) and good electrical insulation properties (~12KV/mm) This series is distinguished by the use of a conventional thermostat mounted on the surface of the heating part, in a compact and economical design.
Other general particularities of these heaters are:
- Not affected by vibration or flexing,
- Lightweight,
- Comply with UL94-VO (flame retardant) and ROHS,- Low smoke and low Toxicity,
- Silicone is non-toxic, and moisture and chemical resistant,
- Very thin profile.
- Consistency control of paints, oils, greases, fats, molasses, adhesives, plastics, mastics, resins,syrups,
- Freeze protection,
- Maintaining liquid temperatures at 45-65°C (115-150°F) in food industry water purification systems,
- Maintain polyester resin at 20-25°C (70-80°F) for spay and pour equipment.
Length (Dimension A): designed to be used on standard container diameters. Consult factory if a custom size is requested.
Width (dimension B): 100mm (4”), 200mm (8”) 300mm (12”), and 400 mm (16”). Heating belts must always be applied on cylindrical surfaces without hoops or ribs.
Ingress protection: IP54.
Minimum ambient temperature: -10o C (+15o F)
Voltage: 220-240VAC.
Power tolerance: ±10% at 20°C
Temperature control: Single pole bulb and capillary thermostat, adjustable from 20°C to 110°C (+50~230°F) or from 50 to 200°C (120-390°F).
Rating 16A 230V.
Power density:
- 0.75 w/cm2 (4.8 w/inch2 ), for usual applications.
- 1 w/cm² (6.5 w/inch2 ) for fast heating applications
Thickness of the flexible silicone foil: 2.5mm. (Optional 3.2mm, for heavy duty applications requiring strong mechanical strength and reinforced insulation).
Insulation resistance: ≥ 10 Megohms.
Operating temperature:
The temperature controlled by the thermostat is that of the heating surface. The temperature of the heated product is generally much lower than that of the surface and depends mainly on the surface power (W/cm²), the quality of the thermal contact with the container, the viscosity, heat capacity and thermal conductivity of the heated product, the good positioning of the heating belt, the set point value, and room temperature (See technical introduction).
You can find in the technical introduction examples of the temperatures reached by silicone heating belts. They represent the temperature that may reach the heating belt if it is not correctly installed (for example: poor thermal contact, empty container or improperly temperature controlled).
