Enclosure Heaters

Enclosure Heaters are made of etched foil heating circuits laminated between thin layers of fiberglass-reinforced, high temperature insulation, silicone rubber, and may be attached to an aluminum mounting plate by factory vulcanization or with PSA (Pressure Sensitive Adhesive). They offer safe and effective protection against problems brought on by temperature variations such as condensation. Using enclosure heaters is a cost-effective way to avoid replacing and repairing equipment damaged by inefficiently controlled temperatures. Custom products available.
