Enclosure Heaters
Reliable Temperature and Moisture Protection for Electrical and Industrial Enclosures

TUTCO Farnam designs and manufactures electric enclosure heaters that help maintain stable internal temperatures, reduce condensation risks, and protect sensitive components. From small electronic control boxes to large industrial electrical cabinets, our Axial Fan Heaters and Crossflow Blower Heaters provide dependable heating solutions for a wide range of enclosure sizes and applications.
Electrical and electronic equipment housed in outdoor and industrial enclosures must operate reliably despite changing temperatures, humidity, and environmental conditions. Cold temperatures and condensation can lead to corrosion, electrical failures, and costly equipment downtime. Whether you need a standard configuration or a custom-engineered solution, TUTCO Farnam can help you select the right heater for your enclosure and operating environment.

Why Enclosure Heating Matters
Outdoor enclosures and industrial control cabinets are designed to protect equipment from the surrounding environment. However, even sealed enclosures can experience significant internal temperature changes. As ambient temperatures fall, the air and surfaces inside an enclosure cool. When surfaces reach the dew point, moisture can condense on electrical connections, circuit boards, and other sensitive components. Equipment that generates its own heat during operation can be particularly vulnerable when powered down overnight. Electric enclosure heaters help maintain a minimum internal temperature, reducing the likelihood of condensation and protecting equipment from freezing conditions.
Protect Against
- Condensation and moisture: Reduce the risk of water collecting on sensitive electrical components.
- Corrosion: Help protect contacts, terminals, and metal components from moisture-related deterioration.
- Freezing temperatures: Maintain temperatures needed for reliable operation in cold environments.
- Electrical failures: Reduce the risk of moisture-related short circuits and equipment malfunctions.
- Temperature fluctuations: Maintain more consistent conditions during seasonal changes and overnight shutdowns.
- Unexpected downtime: Help keep critical electrical and electronic systems operating reliably.

Custom Enclosure Heating Solutions
Not every enclosure has the same heating requirements. Available space, electrical specifications, airflow needs, environmental exposure, and equipment configuration can all influence heater selection. TUTCO Farnam works directly with OEMs and equipment manufacturers to develop enclosure heating solutions tailored to their applications. Whether adapting an existing heater configuration or engineering a completely custom design, our team brings extensive experience in electric heating and thermal management. Our manufacturing capabilities support projects from initial prototype development through high-volume production, including programs requiring thousands of units per month.
Enclosure Heating Solutions from TUTCO Farnam

Axial Fan Heaters
TUTCO Farnam Axial Fan Heaters combine an electric heating element with an axial fan to circulate warm air throughout an enclosure. This combination helps distribute heat around sensitive components and maintain more consistent internal temperatures. Axial Fan Heaters are well suited for applications where compact, fan-assisted heating is needed to protect electrical controls, electronic equipment, and other temperature-sensitive components. Typical applications include: Electrical cabinets, control panels, outdoor electronics, security systems, traffic control equipment, and industrial control enclosures.

Crossflow Blower Heaters
TUTCO Farnam Crossflow Blower Heaters combine electric heating with crossflow air movement to distribute warm air across an enclosure. The blower design provides an alternative airflow configuration for applications where equipment layout, available mounting space, or desired heat distribution makes an axial fan less suitable. These heaters can be configured to meet the heating and airflow requirements of a wide range of electrical and industrial enclosures. Typical applications include: Industrial electrical cabinets, switchgear enclosures, control systems, equipment housings, and custom OEM enclosures.

Frequently Asked Questions
Yes. TUTCO Farnam designs and manufactures enclosure heating solutions for OEMs and equipment manufacturers. Our engineering team can modify existing heater configurations or develop custom solutions to meet specific power, voltage, airflow, size, and mounting requirements. We support projects from initial prototypes through high-volume manufacturing, providing scalable solutions for a wide range of enclosure heating applications.
Enclosure heaters are used wherever electrical or electronic equipment requires protection from cold temperatures and moisture. Common applications include outdoor electrical cabinets, switchgear, traffic signal controllers, ATMs, security cameras, industrial control panels, telecommunications equipment, car wash controls, and automated kiosks. They are particularly valuable in outdoor installations exposed to seasonal temperature changes and overnight shutdowns.
Both TUTCO Farnam heater designs combine electric heating with forced airflow to distribute warmth throughout an enclosure. Axial Fan Heaters use an axial fan to move heated air through the enclosure, while Crossflow Blower Heaters use a blower to distribute air across a wider outlet. The best choice depends on enclosure size, available mounting space, airflow requirements, and equipment layout.
Condensation forms when surfaces inside an enclosure cool below the dew point of the surrounding air. Enclosure heaters help maintain internal temperatures above this threshold, reducing the likelihood of moisture collecting on sensitive components. Fan-assisted heaters also circulate warm air throughout the enclosure, helping minimize cold spots where condensation could develop.
The proper heater size depends on several factors, including enclosure dimensions, desired internal temperature, minimum outside temperature, and heat generated by existing components. TUTCO Farnam's Enclosure Heater Calculator allows you to enter these parameters to estimate your heating requirements and identify suitable heater options.
Enclosure heaters help protect electrical and electronic equipment from cold temperatures, condensation, and moisture-related damage. By maintaining a consistent internal temperature, they reduce the risk of corrosion, electrical failures, and equipment downtime. They are commonly used in outdoor electrical cabinets, control panels, switchgear, and other equipment enclosures.
