SILICONE RUBBER HEATERS
IMPROVE HEAT TRANSFER, SPEED WARM UPS AND DECREASE WATTAGE REQUIREMENTS
Watlow silicone rubber heaters are rugged, yet thin, lightweight and flexible. Use of these heaters is limited only by the imagination. Heat can be put where it is needed. These silicone heaters improve heat transfer, speed warm ups, and decrease wattage requirements.
Fiberglass-reinforced silicone rubber gives the heater dimensional stability without sacrificing flexibility. Because very little material separates the element from the part, heat transfer is rapid and efficient. The silicone rubber heaters are constructed with a wire-wound element or an etched foil element. The heater construction creates a very thin heater allowing it to fit applications where space is limited.
- Designed to the exact shape and size needed which conforms to the component and/or equipment
- More than 80 designs available immediately from stock reduces downtime
- Constructed with wire-wound or etched foil elements provides the desired flexibility for many dynamic applications and delivers low mass and easily repeatable distributed watt densities
- Moisture and chemical-resistant silicone rubber material provides longer heater life
- Vulcanizing adhesives or fasteners allows heaters to be easily bonded to parts
- “HIGH-TEMPERATURE TUBULAR HEATERS” already exists in your wishlist

SOLID STATE RELAYS
MORE FOR LESS: LONGER HEATER LIFE AT LOWER COST
Watlow solid state relays (SSR) offer many of the advantages of solid state power controllers, but at a lower cost. Watlow’s extensive knowledge in power controller design led to the development of a special fast cycle input card that enables a solid state relay to operate from a standard 4-20mA instrumentation command signal. Test results show that zero-cross solid state relays in combination with the fast cycle card promote better temperature control and longer heater life than slow cycle relays. Through a time proportional cycle rate of 1⁄10 of a second, heater life will be extended.
Both low and high voltage solid state relays are available from 24 to 660VAC. All ac output models include back-to-back silicon controlled rectifiers (SCRs) for a more rugged design than the traditional triac-based solid state relay. The internal design allows it to tolerate high currents and harsh electrical environments of heavy industry. Watlow also offers a switched VDC model for dc heating applications.
Watlow provides all of the components necessary for trouble-free operation. This includes two standard convenience items: a thermal foil to ensure proper thermal transfer from the relay to the heat sink and belleville washers to ensure that the relay is mounted with sufficient pressure to enable good heat transfer. Matched semiconductor fuses and heat sinks are available to complete the power switching package.
