High Flow Preheater Battery (36V)

The Pandrol High Flow Preheater 36V (HFP 36V) is a universal preheating system for use when welding on site. It has been designed to replace the need for most existing equipment currently used to raise the temperature of the parent steel before welding.

The HFP 36V is battery powered and fully automated for easier, more reliable operation: the ignition, timing and stop require no manual interference or flame adjustment. Unlike most existing preheating systems it uses propane/acetylene rather than oxygen, reducing costs and making the equipment light and easy to carry around on site. Compact and robust, it has been designed to withstand the most extreme track conditions.

Technical Features

The preheat technology used by the HFP is less sensitive to pressure adjustment than oxy-propane. It provides a uniform preheat between the head and bottom of the rail.

The HFP is fully automated, with automatic ignition, built-in timer and automatic stop. No manual flame adjustment is required.

The built-in timer can be pre-set by the welder for accurate preheating time.

2 long lasting batteries of 18V with 8.0 Ah, for a safer autonomy.

There is a single torch height for all welds and no adjustment is needed.

With its compact size (L: 740mm, W: 300mm, H: 295mm) and light weight (19kg), the HFP can be easily handled by only one person.

Advantages

The HFP’s built-in timer increases accuracy, improving quality and reducing the defect rate of weld due to preheating.

Providing a uniform preheat between the head and bottom of the rail reduces stress in the weld.

As the system is fully automated it is easy to use. Less training is required and it is straightforward for new welders to learn to operate.

The use of propane rather than oxygen results in significant cost and weight savings.

The preheater does not require any specific maintenance which makes it easy to manage during daily welding operations.

The HFP is a complete system that can be used to replace most existing preheating equipment.
