In rail transportation, there’s no room for “almost.”
Every journey depends on absolute safety, uninterrupted performance, and an unwavering commitment to protecting passengers. And when winter hits, the stakes rise sharply.
Because cold weather doesn’t just slow trains.
It shuts down doors, freezes sensors, stalls electronics, and jeopardizes systems that millions rely on every day. Ice is not a nuisance — it’s a threat to reliability, continuity, and safety.
This is why the leaders in modern rail engineering know one truth:
freeze protection is mission-critical, and only solutions that adapt, conform, and comply with the toughest safety standards survive on the network.
And here’s where OHMVO steps in.
With EN45545 R1/R7 HL3 certification — the highest European requirement for fire, smoke, and toxicity — OHMVO delivers silicone heating systems capable not only of preventing ice but also of meeting the strictest regulatory demands. No compromises. No shortcuts.
Because keeping a train warm isn’t about comfort.
It’s about protecting passengers, guaranteeing performance, and meeting the gold standard of railway safety.
When your heaters adapt to every curve, every assembly, every complexity…
you don’t just defeat the winter —
you elevate the entire rail system.
European Silicone Heaters: Meeting EN45545 Standards for Railway Applications
The Technical Imperative: Preventing Ice and Operational Failure
Cold weather directly translates into operational risk. Ice accumulation can lead to the mechanical failure of critical moving components and the malfunction of essential electronic systems, halting service and compromising safety.
- Critical Component Freeze Protection: Engineers must find reliable solutions to prevent the appearance of ice so that vital exterior components remain operational. This includes maintaining the function of train doors and various sensors that govern signaling and movement. Without reliable, integrated heat, a simple drop in temperature can render complex systems inert. Even secondary systems, such as hydraulic lift gates used in transport and logistics, are highly susceptible to performance issues caused by low temperatures.
- Engineered Adaptability: Traditional, rigid heating elements are often ill-suited for the complex shapes and assemblies found across rolling stock. They struggle to maintain the close contact necessary for efficient heat transfer, leaving cold spots where ice can easily form. The solution requires a material capable of perfect conformity and durability.
The Safety Mandate: Navigating EN45545 Certification
In the European railway sector, achieving operational reliability is inseparable from safety certification. The EN45545 standard governs fire safety across rail vehicles, focusing on the material’s reaction to fire (e.g., flammability, smoke opacity, and toxicity).
For a component to be used in a train, it must meet rigorous safety requirements. Simply providing heat is insufficient; the heating solution itself must comply with the most demanding hazard levels.

OHMVO, as an industrial company specializing in the design and manufacturing of silicone heating blankets for rail industry, possesses the necessary EN45545 R1/R7 HL3 certification, which allows it to provide safe, compliant thermal solutions for the railway industry. This compliance is critical as it validates the use of the product in high-risk environments, ensuring that the silicone compound does not compromise fire safety, even under harsh operating conditions.
“In the pursuit of precision and efficiency, flexible heating solutions have redefined the way industries manage temperature control.”

Silicone Heaters: Tailored Solutions for Safety and Comfort
The inherent properties of silicone rubber heaters make them the ideal component for both regulatory compliance and thermal performance in the rail sector:
1 Safety and Longevity:
Silicone provides outstanding sealing and electrical insulation properties and offers a very long working life. Furthermore, our products often incorporate fiberglass for mechanical reinforcement, adding durability in demanding industrial environments.
2 Unmatched Customization:
Success in rail applications requires specialized, tailor-made products. The ultimate goal is to achieve a real perfect “Custom design” that fits specific railway components and complex geometries, ensuring efficient heat transfer and freeze protection. This high degree of customization is crucial for the safety of assets and personnel.
3 Enhancing Passenger Experience:
Beyond essential freeze protection, silicone heaters also play a vital role in passenger comfort. They are used as railway coach heaters, ensuring a comfortable environment for travelers. They can also be integrated into hot plates or chairs for health professionals, further improving comfort in transit.
OHMVO’s certification under UNE-EN ISO 9001:2015 for quality management, alongside the specialized EN45545 certification, underpins our authoritative position in delivering high-value thermal solutions to large industrial sectors. We rarely deal with buyers; instead, we prioritize advising the engineer—the technical prescriber—to co-manufacture the best tailor-made product.
If your project involves the railway industry and requires bespoke thermal solutions that adhere to the highest European safety standards, look no further than our technical expertise.
