A Breakthrough Innovation for Heat Shrinking in the Power Industry
Heat shrink tubing and gas burner heads for heat shrinking may seem like a niche topic, but that is precisely why traditional solutions have remained unchanged for years—until now.
Anyone who has worked with heat shrink tubing knows the frustration of uneven heat distribution and difficult angles, making efficient shrinking a challenge. Melbye, in collaboration with Framti Production, has developed a revolutionary solution to this problem—Ring of Fire.
What is Ring of Fire?
The name says it all. Instead of the traditional single-point burner design, Ring of Fire distributes heat evenly around the entire shrink tube—a true ring of flame.
“This innovative design ensures faster, more consistent shrinking, eliminating cold spots and reducing the risk of material damage,” says Gunnar Huynh, Product Manager at Melbye.
The product is the result of extensive industry experience and direct customer feedback. During the pilot phase, it quickly became clear how much more efficient this solution is compared to conventional alternatives.

No Major Investments – Seamless Integration
A key advantage of Ring of Fire is that it requires no major reinvestment. The burner head is fully compatible with the Sievert Promatic system, making it an easy upgrade for professionals in the field.
The product is built for harsh industrial environments, using stainless steel, brass, and ABS plastic, ensuring durability and longevity even in the toughest conditions.
Developed in Norway – Built for the Global Market
The Ring of Fire is designed and developed in Norway, a result of long-term collaboration between Melbye, Framti Production, trusted suppliers, and industry professionals. This innovation is a game-changer for large-scale electrical power applications, providing a more efficient, reliable, and cost-effective solution.
