Introduction
Let’s talk about the Nissei ASB 150DP heater tube. It’s a direct replacement for the heating element in your Krones Contiform stretch blow molding machine, but here’s the best part—it does the same job as the original, for a much friendlier price tag. No need to break the bank on OEM parts when you can get the same performance without the premium cost.
Power, Voltage, and the Practical Stuff
This thing is built for the job. It runs at 2500W on 400V, which is exactly what you need to generate the kind of heat density that gets PET preforms ready fast. The 300mm active length focuses all that energy right where it needs to be, so the preform wall hits the perfect temperature before it gets stretched. Now, it’s a direct fit, but that doesn’t mean it’s just plug-and-play. The 400V supply needs a solid electrical setup, and that 2500W output puts out a lot of heat. You’ll want to make sure your cooling and thermal management systems are in good shape. If the machine runs too hot, you’ll shorten the life of the lamp.
What’s Inside, and Why It Matters
Inside, the ASB 150DP uses a shortwave halogen design, all wrapped up in a high-purity quartz envelope. This means you get near-instant response—flip it on, and it’s hot. Flip it off, and it’s done. The heat stays stable throughout the cycle, which is exactly what you need. The outer surface has a special reflector coating that directs the infrared energy straight onto the preform. Less wasted heat means better efficiency, and that’s a good feeling when you’re running a tight operation. For the connection, it uses an R7s connector. This is a standard interface that lines up perfectly with the sockets on your Contiform machine. It makes installation straightforward and ensures a solid, reliable connection. No more worrying about hot spots or connection issues that can cause failures.
On the Contiform: Performance That Feels Right
When you’re running a Contiform machine, consistency is everything. The ASB 150DP delivers that. The shortwave heat penetrates quickly, getting the preform to the right temperature without scorching the surface. That means you get predictable bottle quality, cycle after cycle. For your maintenance team, the appeal is simple: it’s a component that performs just like the original, but helps you keep operating costs down. It’s a straight swap, so you don’t have to spend time re-engineering anything. Just double-check your voltage, make sure your cooling is good, and wire it in. You get the same heat output as the OEM, at a lower overall cost.
