Cooling water hoses

PROTECTOR™ electric hose: the specialist for extreme temperatures in melting and induction furnaces

Optimum cooling under the highest loads in melting furnaces, induction furnaces and electric arc furnaces.
The PROTECTOR™ electric hose h is the ideal solution for demanding industrial applications that require high temperature resistance and mechanical strength. Specially developed for extreme conditions such as in melting, induction and arc furnaces, it guarantees reliable and long-lasting performance even under the highest loads.

With its exceptional resistance to heat, pressure and external influences, it is the perfect choice for environments that demand maximum resilience and safety. Its long service life also makes it economically attractive for a wide range of applications.

Advantages of the PROTECTOR™ electric hose:

  • Excellent temperature resistance: The PROTECTOR™ electric hose can withstand temperatures from -30 °C to +80 °C and is heat-resistant up to +110 °C for short periods, making it ideal for transporting hot water.
  • High operating and burst pressure: With an operating pressure of 10 bar, a test pressure of 15 bar and a burst pressure of over 30 bar, the hose offers a high level of safety and reliability for demanding applications.
  • Excellent electrical insulation: An electrical resistance of R > 10¹¹ Ω/m and a dielectric strength of > 6 kV/mm guarantee maximum protection against electrical hazards.
  • Self-extinguishing and robust: The hose cover is self-extinguishing, flame-retardant and conditionally oil-resistant, which makes it particularly safe and durable.
  • UV and ozone resistant: Thanks to its resistance to UV radiation and ozone, the hose is ideal for use in outdoor areas and under difficult environmental conditions.
  • Stable length properties: Even at maximum operating pressure, the change in length is only +/- 3 %, which ensures precise installation and reliable operation.
  • High resistance: The combination of weather-resistant cover and hot water-resistant core makes the hose the ideal choice for a wide range of applications.
  • REACH-compliant: The hose meets all relevant environmental and safety requirements, making it a sustainable and safe solution.

Material and properties:

  • Core: The hose is made of high-quality EPDM rubber, which is known for its excellent resistance to hot water.
  • Hardness: With a Shore hardness of 65 +/- 5 Shore A, the hose offers an ideal balance between flexibility and resistance.
  • Pressure carrier: The PROTECTOR™ electrical conduit contains a temperature-resistant technical fiber that provides additional stability.
  • Cover: The mixture of CR/EPDM/BR material ensures high resistance to external influences, with a Shore hardness of 65 +/- 5 Shore A.

Additional options and customizations:

The PROTECTOR™ electrical conduit is available in 40-metre lengths and can be individually adapted to specific requirements. Its high temperature resistance and exceptional pressure resistance make it indispensable for industrial processes.

Areas of application:

  • Cooling water hose: Perfectly suited for high-temperature applications where reliable cooling is crucial, such as cooling circuits.
  • Water-cooled high-current cables: The hose supports optimum cooling and safety of water-cooled cables in high-current electrical applications.
  • Induction melting furnaces: Ideal for cooling systems in induction melting furnaces where high performance and reliability are required.
  • Electric arc furnaces (EAF): Proven in electric arc furnaces due to its ability to cool the electrodes efficiently and safely.
  • Ladle furnaces (LF): Ensures constant and reliable cooling in ladle furnaces, even under demanding conditions.
  • ESU systems: The hose is ideal for supplying cooling water in ESU systems (electroslag remelting systems) that require high precision and safety.
  • Holding ovens: Supports temperature control in holding ovens through efficient water cooling.
  • Induction heaters and hardening systems: Used in systems such as block and strand heaters and in hardening systems to ensure constant cooling of induction systems.
