Description

The Ekyrail Heater Assembly – 3073-200 is engineered to provide dependable heating for locomotive systems exposed to cold environments. Designed specifically for railway applications, the unit helps prevent freezing and ensures proper operation of sensitive components during low-temperature conditions.

The system features a stainless steel heating element with high-density insulation, delivering consistent and efficient heat output. An integrated thermal control device (T.O.D.) automatically activates the heater at low temperatures and deactivates it once optimal conditions are restored, ensuring energy efficiency and system protection.

Built with railway-grade materials, including EXANE® high-temperature cables and a sealed thermal sensor housing, the heater assembly is designed to withstand vibration, moisture, and harsh environmental conditions. Its robust construction ensures long-term reliability in demanding rail operations.
