Common cartridge can be divided:
1) High power density (heat area surface power 10~25 w/cm²) Working temperature≤450 degrees.
2) Middle,low power density (heat area surface power 5~11 w/cm²) working temperature≤ 300 degrees voltage 12~250 V (or as requirement)
High Density Construction :
High-quality stainless steel construction provides long-lasting protection even in the most rugged industrial environments
Protected with a stainless steel sheath, their watt density can reach 50 w/cm² and their operating temperature can go up to 800°C.
