• Holding Furnace
• Inductive Billet or Bar Heater
• Induction Hardening Systems

For the safe operation of inductive machines the control of the water cooled inductor, the construction of the emergency catching pit and the cooling water electro hose is very important.

Therefore we grant a 5 year guarantee for quality and workmanship from date of delivery.

The improved Protector™ HT - Fire - Protection - Sleeving, now with up to +300°C higher temperature resistance, offers you protection for cables and hose lines against radiation heat, direct exposure to flames, slag and
liquid metal splashes of up to +1500°C.

PROPERTIES:
- High temperature resistance:
  Silicone cover: >+300°C, short term up to +500°C
   Inner sleeve: >+800°C, maximum temperature (short term) +1100°C
- Fire-retardant and self-extinguishing
- Dielectric strength of > 12 kV
- Free of halogens
- REACH-compliant
- Type approval from Germanic Lloyd
- Approved for rail use according to EN 45545-2:2016-02-R22/R23-HL3
- 100% made in Germany

Available diameters:
DN 10, DN 15, DN 20, DN 22, DN 25, DN 28, DN 30, DN 32, DN 35, DN 40, DN 50 + DN 60 in rolls of approx. 25 metres each.

With a minimum production volume of 250 m the Protector™- HT – Fire - Protection -Sleeving is available in whichever colour and print markings that you desire!

The new Protector™- Fire - Protection - Sleeving Type “Heavy” with its extra heavy-duty construction consists of an especially heavy Therm-Textil™ fabric with a thick red silicone coating. It has been specially designed to provide robust protection in foundries and steelworks against slag and liquid metal splashes.

Liquid metal splashes rolls off and the cables or hoses are better protected against the high temperatures due to the thicker material.

PROPERTIES:
- High temperature resistance:
  Silicone cover: >+250°C, short term up to a maximum of +300°C
  Therm-Textil™ fabric: >+700°C, short term up to +750°C
- Fire-retardant and self-extinguishing
- Highly effective insulation
- Durable and robust
- Not hazardous to health
- REACH-compliant

As with the Type Variable, there are four fastener types available and are produced to order in our own processing facility.

The Protector™ - Fire – Protection - Sleeving Type Variable
with four different seal types for the retroactive installation of hose and cable protection. Custom production of internal diameter and custom lengths are possible at short notice in our workshop.

PROPERTIES:
- High temperature resistance:
  Silicone cover: >+200°C, short term up to +250°C
  Therm-Textil™ fabric: >+700°C, short term up to +750°C
- Fire-retardant and self-extinguishing
- Not combustible in accordance with DIN 4102 A1
- Not hazardous to health
- REACH-compliant

The Protector™ - Silicone-Electric-Hose is a non-conductive cooling water hose which is especially disigned for usage in induction plants (inductive billet or bar heater) and  other electrical systems such as rectifiers and power converters.

Characteristics:

• Very good flexibility and form stability
• No kinking even at smallest bending radius
• No flattening
• Free flow of cooling water is always guaranteed
• Increase ozone resistance and therefore slower aging process
• Resists high temperature of media and environment
• Long working life

Technical characteristics: High temperature resistance of: +300 °C (Silicone +500 °C (Aramide)

• Dielectric strength according to VDE 03030: > 40 kV
• Surface resistance according to VDE 0303: 1012 Ohm
• Arc resistance according to VDE 0441: 80 -100 seconds
• Working pressure: 12 bar, burst pressure: 40 bar
