We recommend factory assembled laser sleeves for the use of the ISM mineral insulated heating circuits, because the on-site assembly requires much experience. With the laser- method, a high quality of the sleeve and thus a long service life of the trace heating system is guaranteed.
The mineral-insulated heating cable ISM is due to their structure very sturdy and safe for use in industrial and hazardous environments. The different types of Jackets are highly resistant to chemical attack. The specific resistance of ISM will cause the power output increases or decreases by changing the length of the heating cable. The heating cable will be soldered or laser-welded with connection sleeves to special cold-ends (Standard length 1,2m). Depending on the application and temperature requirements, various outer jackets made of stainless steel, Cupronickel or Incoloy are available.
