OHMVO’s commitment to innovation underscores the transformative potential of tailored silicone heaters in enhancing rail systems. Let’s talk about the importance of safety and efficiency, as well as the benefits of lightweight solutions !

Tailored silicone heaters represent a pivotal leap in rail innovation, seamlessly blending engineering excellence with efficiency to elevate the reliability and performance of modern rail systems.



Overview of Silicone Heating Solutions for Rail Systems

Silicone heating solutions are essential for keeping rail systems working well. The etched foil resistor element encased in a silicone mat spreads heat evenly, which helps to keep things running smoothly and deal with tough weather. They make sure passengers are comfortable by controlling temperature, warm up HVAC ducts and even prevent cabin windows from icing over.

The essential role of silicone heaters in modern rail infrastructure

Silicone heaters can be used to:

  • Keep Things Just Right. Silicone heaters embedded in floors or walls compliment HVAC systems for passenger and driver comfort and allow for wider coaches in new trains that incorporate this technology.


  • Safety. Silicone heaters make sure sensitive parts like signals and switches stay at the right temperature and stop equipment from freezing up, so trains can keep moving safely. They avoid condensation on driver mirrors and can be installed to prevent driver cabin windows and pedals from icing overnight. Mobility access ramps also use silicone resistor technology to avoid the accumulation of ice and snow and ensure the safety of passengers with limited mobility.


  • Stop Ice. In snowy areas, silicone heaters prevent ice from forming on trains and tracks. This helps avoid accidents and delays caused by icy build-up.


  • Save Energy. Silicone heaters are good at using less energy compared to older heating methods. They’re flexible and can heat things up precisely, which saves power.


  • Fit Anywhere. Silicone heaters can be made to fit any shape or size, so they can be used in different parts of trains without taking up too much space or changing the design. Installation can be mechanical, vulcanized or with heat resistant adhesive.

Tailored heating solutions: Beyond standard offerings

Tailored heating solutions are specifically designed to meet the unique demands of modern railways railways in compliance with industry standards EN45545. These heaters are not one-size-fits-all. They are adjusted to maintain precise temperatures or heat specific parts as required by the railway. They are versatile enough to withstand various weather conditions, and can be integrated with existing railway systems, whether they are retrofitted into older infrastructure or incorporated into new designs.

Moreover, tailored heating solutions involve leveraging the latest innovations and technological advancements in heating technology. This can result in solutions that not only meet current needs but also anticipate future challenges. Ensuring that railway infrastructure remains at the forefront of technological advancement.


 Engineering excellence: Customization at its core

Customized silicone resistor mats are all about top-notch engineering.

The bespoke, etched-foil circuit is designed to maximize the temperature uniformity of the heater and is encased in a unique blend of silicone rubber, formulated to meet particular requirements, such as resisting high temperatures or where a thermally conductive formula is required.

Ensuring continuous operation: From fresh to waste water management

In water systems, it's super important for things to work smoothly all the time. Customized silicone heating mats are invaluable in colder climates to keep fresh and waste water systems from freezing. Heaters are fixed to water tanks and wrapped around pipes and valves, keeping them warm and stopping heat from escaping. This saves energy and makes sure tank and pipe contents don’t freeze in cold weather, avoiding damage and making sure the fresh water can flow to toilets and sinks. Underslung railway equipment often requires increased protection: Silicone foam adds a thermal layer of protection to heaters that are fixed to outdoor water and waste water tanks. A mechanical protection, such as sheet metal will protect the heater and tank against damage from ballast .

Complying with Industry Standards: EN45545

The EN45545 standard sets safety requirements for materials used in railway applications, ensuring they can withstand fire and reduce smoke and toxicity. It helps guarantee that railway components, like Ohmvo silicone resistors, meet specific safety levels, enhancing overall rail system safety.

Railway components must endure harsh operating conditions, underscoring the significance of compliance with safety standards. For example, silicone heaters must withstand ignition and halt the spread of flames to safeguard passengers in fire incidents. Moreover, minimizing smoke emission is crucial for maintaining visibility and facilitating efficient evacuations during emergencies. Additionally, restricting toxicity levels is imperative to mitigate health hazards arising from exposure to harmful gases or substances released during fires.

By meeting these standards, rail system components affirm their reliability in railway operations, fostering confidence among stakeholders and prioritizing passenger safety.

Varied IP Ratings for Diverse Rail Environments

Railway settings vary a lot, from busy city trains to tough cargo routes. Making sure electrical gear can handle these conditions is super important. That’s where the Ingress Protection (IP) rating comes in. It shows how well gear can resist dust or water for example. Knowing these ratings and picking the right one for rail gear is key for keeping things safe and reliable.

Understanding IP ratings and their significance

The IP rating is expressed as “IP” followed by two digits. Here, each digit represents a different aspect of protection.

  • First Digit (Protection against Solids)
    Ranges from 0 (no protection against solids) to 6 (complete protection against dust ingress).                                  Indicates the level of protection against solid objects such as dust, dirt, and debris.
    Higher numbers indicate greater protection.
    Digit Description Protection Level.


  • Second Digit (Protection against Liquids)
    Ranges from 0 (no protection against water ingress) to 8 (protection against long periods of immersion under pressure).
    Indicates the level of protection against the ingress of water.
    Higher numbers indicate greater protection.
    Digit Description Protection Level.


For example, an IP67-rated device offers complete protection against dust (first digit) and can be submerged in water up to 1 meter for 30 minutes (second digit).

Selecting the right IP rating for your rail applications

Choosing the appropriate IP rating for rail applications requires careful consideration of environmental factors, moisture exposure, hazards, mounting locations, regulations, and durability.
