1. Silicone Rubber Heater For Cabinet Dehumidification (Anti-Condensation)

Hongtai manufactures professional-grade Silicone Rubber Heater For Cabinet Dehumidification units designed to protect sensitive electronics and high-voltage switchgear from moisture damage. Unlike standard flexible heaters, these units are factory-vulcanized onto a rigid black aluminum mounting plate.

This design functions as a highly efficient radiator. The Silicone heater Power equipment Moisture-proof dehumidification heating 50W/100W system raises the internal enclosure temperature slightly above the ambient dew point. This prevents the formation of condensation (dew), which is the leading cause of short circuits, busbar corrosion, and component failure in outdoor or humid indoor environments.

2. Key Technical Features

• Integrated Aluminum Plate: The silicone heater is bonded to a black anodized aluminum alloy plate. This acts as a heat sink to radiate warmth evenly and provides rigid mounting points for easy installation.

• Moisture Proof: The heating element is fully encapsulated in fiberglass-reinforced silicone rubber, offering IP54/IP65 protection against dust and humidity.

• Safety & Reliability: Unlike ceramic heaters with exposed coils, our Silicone Rubber Heating Plate For Cabinet Dehumidification Heater has no open flames or exposed live parts, making it safe for compact control panels.

• Space Saving: The ultra-thin profile (compared to bulky fan heaters) allows installation in tight spaces within switchgear cabinets and terminal boxes.

• Standard Configuration: Commonly supplied as a Silicone Rubber Heating Pad Heat Mat Heater 90x150mm AC 220V for Electric Cabinet applications.

3. Technical Specifications & Dimensions

We offer standard sizes compatible with most industrial enclosure mounting footprints (Rittal, Schneider style, etc.).

4. Industrial Applications

This 50/100W Rubber Heating Mat assembly is the industry standard solution for:

• High Voltage Switchgear: Preventing flashovers caused by condensation on busbars.

• Outdoor Control Panels: Protecting traffic signal boxes and telecom cabinets from morning dew.

• Wind Power Converters: Moisture protection in nacelle control cabinets.

• ATM & Vending Machines: Keeping internal mechanics dry and operational in cold weather.

5. Why Choose the Aluminum Plate Version?

While we sell flexible pads, the Silicone Rubber Heater For Cabinet Dehumidification with the aluminum backing plate offers specific advantages for enclosure builders:

1. Ease of Installation: You simply screw the plate onto the cabinet wall or mounting rails. No adhesive needed.

2. Heat Dissipation: The aluminum plate expands the effective heating surface area, warming the cabinet air more efficiently by convection than a pad alone.

3. Durability: The plate protects the silicone rubber from accidental impact or abrasion during cabinet maintenance.

6. FAQ

Q: Does this heater need a thermostat?

A: For basic anti-condensation, many users run the 50W heaters continuously. However, for energy efficiency and precise control, we recommend pairing the Silicone Rubber Heating Plate For Cabinet Dehumidification Heater with a DIN-rail Hygrostat (humidity switch) or Thermostat set to maintain 5-10°C above ambient.

Q: What is the surface temperature of the heater?

A: A 100W heater on an aluminum plate typically reaches a surface temperature of approx 150°C-180°C in free air. The aluminum plate helps dissipate this heat into the cabinet air. Ensure wires are routed away from the heater face.

Q: Can I install it horizontally?

A: Vertical installation (mounting on the side wall near the bottom) is best for promoting natural convection airflow (chimney effect) to dry the entire cabinet.
