Hollow drills for PSM-500

Hollow drills for PSM-500

When heat exchanger tubes are heavily fouled or completely clogged with deposits, the PSM-500 system offers an effective solution. Hollow drills are solid rods featuring an integrated drill head and a hollow core. This design allows water to be fed directly through the drill, ensuring continuous cooling of the drill head and flushing of loosened deposits from the tubes during cleaning.

Practical information

• Goodway® hollow drills are designed for use with the PSM-500 drilling system and are effective at drilling through and removing hard deposits, such as limescale, from heat exchanger tubes.
• These precision-engineered drills are sold separately and can be directly connected to the PSM-500 system without the need for additional couplings, ensuring a fast and secure setup
• Hollow drills are supplied in fixed lengths and cannot be connected to extend their reach.

2-step cleaning process

When hard waterformed deposits, such as calcium carbonate, completely block heat exchanger tubes, the Goodway® PSM-500 drilling system is the ideal tool to restore flow capacity. While the PSM-500 reopens the tubes, it does not fully clean the internal surfaces. For optimal results, a two-step cleaning process is recommended.

• Step 1: Use the PSM-500 drilling system, along with drill rods, to remove blockages and restore the flow capacity of the tubes. This step clears the way for efficient circulation in the next stage.
• Step 2: Once the tubes are open, connect a Goodway® chemical cleaning pump system to circulate ScaleBreak descaling solutions. This will thoroughly dissolve any remaining waterformed deposits on the tube walls.

By implementing this two-step process, you ensure the heat exchanger is completely cleaned, enabling it to return to optimal operational performance.
