Applications

Whenever the application has increased requirements for chemical, oil or UV resistance or IP protection, butyl heaters are the optimal choice:

Chemical and process industry: In the chemical and petrochemical industry, butyl heaters ensure stable process parameters in reactors, storage tanks, and pipelines. Precise temperature control prevents undesirable reactions and optimizes production processes.

Food and pharmaceutical industries: Here, compliance with strict temperature ranges is essential. Heaters ensure constant heating in production and storage areas , preventing frost and overheating. This contributes significantly to product quality and safety.

Battery applications: Especially in modern energy storage systems, a minimum temperature is crucial for the performance and service life of batteries . Butyl heaters can help reduce temperature gradients within battery modules even in the harshest outdoor conditions, improving efficiency and safety.

Mechanical and systems engineering: In mechanical systems such as pumps and valves, the heaters minimize the risk of icing and uneven temperature profiles. Their flexible adaptability to complex surfaces supports trouble-free operation and extends the service life of the systems.

Outdoor electronics: For outdoor applications, such as weather stations, telecommunications equipment, or interconnected IoT systems, stable temperatures are essential. The robust butyl heaters provide reliable protection against temperature fluctuations, frost and UV exposure, ensuring the operational readiness and longevity of outdoor electronics.

Whether in stationary systems or in dynamic, reinstallable systems – the flexibility and adaptability of the butyl heaters enable use in almost every industrial sector.

Product advantages

Whether in stationary systems or in dynamic, reinstallable systems: The butyl heaters convince with a number of advantages:

Robustness and durability: The use of butyl rubber as a base material gives the heaters exceptional resistance to UV radiation, chemicals, water, and oils, and is even submersible. These properties guarantee reliable operation even under extreme conditions and in aggressive environments. The robust construction reduces maintenance requirements and extends the service life of the heating systems, resulting in a significant reduction in downtime and operating costs.

Precise heat distribution: Thanks to the thermal stability of ±0.5°C, butyl heaters allow for uniform and controlled heat distribution. This enables precise adjustments of process parameters, which is crucial in many industrial applications—especially in chemical and pharmaceutical production—to ensure product quality and safety. Precise temperature control minimizes the risk of quality loss and undesirable reactions in the process.

High flexibility and adaptability: The variable dimensions of the butyl heaters and the minimal bending radius of 3.175 mm enable flexible integration into a wide variety of systems. Whether flat, curved, or spherically shaped surfaces – the heaters adapt to virtually any component. This allows engineers to develop customized heating solutions that are precisely tailored to the specific conditions and requirements of each application.

Easy to integrate and reinstall: Butyl heaters can be easily adapted , installed, and removed again if necessary. This feature makes them particularly attractive for applications where regular maintenance or retrofitting is necessary. The simple integration not only saves time, but also reduces the costs of implementing new heating systems.

Reliability under extreme conditions: The ability of butyl heaters to operate stable under extreme temperatures ranging from -45°C to +121°C, as well as their resistance to most harsh environmental conditions, ensure continuous and reliable operation. This is especially important in outdoor or submersible applications, critical processes, and demanding environments where a heating system failure could lead to significant production disruptions. The robust design thus provides a high safety factor, which is essential for the long-term planning and operation of industrial plants.

Energy efficiency and high power density:
With a maximum power density of 0.775 W/cm² , the butyl heaters ensure fast and efficient heating. The ability to control the heating output in multiple zones allows for demand-based energy supply. This leads to optimal use of energy and contributes to reducing the system's overall energy consumption.

Implemented projects

Projects that have already been realized demonstrate the versatility and efficiency of heaters.

Important criteria for selecting your heater

When selecting butyl heaters, we recommend that you consider some key aspects to ensure that the solution is optimally tailored to your application:

Process and temperature requirements: First, determine the temperature range and temperature stability required for your application. Our butyl heaters operate at temperatures down to -45°C and generate heat up to +121°C, ensuring precise temperature stability with a tolerance of ±0.5°C. Compare whether these parameters match the thermal requirements of your processes. If you need higher temperatures, we recommend flexible silicone, Kapton, or all-polyimide heaters, which can generate temperatures from +230°C to +300°C. If even higher temperatures are required, our MICA heaters are available; when clamped to your heat sink, they can reach temperatures of up to 600°C.

Power density and electrical requirements: Specify the operating voltage and the required heat demand per unit area. With a maximum power density of 0.775 W/cm² and a maximum operating voltage of up to 240 V, our butyl heaters offer versatile options. Check whether these values match the performance requirements of your system. If the operating voltage in your application is higher, we recommend taking a look at our silicone heaters, which can operate with a maximum voltage of 750 V, or our polyester heaters, which can operate with a voltage of up to 1000 V. For higher power densities, we recommend our Kapton® or all-polyimide heaters with 18.6 W/cm² or our MICA heaters with up to 23.35 W/cm².

Dimensions and geometric adjustments: Determine the required dimensions and shape of the heating surface to be optimally integrated into your system. Thanks to the thin construction (minimum thickness 1.27 mm, over lead area 2.78 mm) and high flexibility (bending radius 3.175 mm), our butyl heaters adapt precisely to tight installation space requirements and complex geometries. The maximum surface dimensions for our butyl heaters are 889 mm x 1143 mm. If you need larger dimensions for your applications, explore our;silicone heaters.

Environmental conditions: Specify whether special conditions such as water resistance or high resistance to oil, chemicals, and radiation are required. Our butyl heaters are both waterproof and submersible and offer robust performance even in the most demanding environmental conditions such as chemicals, oil or strong UV radiation.

If you need a heating solution that is vacuum or cleanroom compatible, we can recommend you our Kapton®- or all-polyimide heaters.

Additional functional requirements: If your application requires multi-zone or multi-layer heating circuits, consider these aspects in your planning. Our butyl heaters support both graduated heating power densities and a multi-layer structure, allowing even complex thermal profiles to be realized. Sensors, controllers, connectors, and other components can also be integrated according to your requirements. Learn more about this in our heater assemblies .

These criteria serve as a practical guide for selecting the right product for your application. Take advantage of our many years of expertise to identify the optimal solution for your specific requirements.
