HydroDrill™ Tube Cleaning System
Designed to solve the most difficult deposit problems, Conco HydroDrills combine powerful rotary tube cleaning action with a 7.6 to 11.4 LPM water flush to clear even completely blocked tubes. They are ideal for cleaning all types of heat exchangers including chillers, oil coolers, condensers and process manufacturing tubes.
Conco offers two versions of the HydroDrill, the Dominator and the Mitee Mouse II. The Dominator is our large heavy-duty unit. It is powered by compressed air and a booster pump delivering 17.2 BAR at a minimum of 70 LPM (121 LPM) recommended and is designed to clean tubes from 13 mm to 70 mm O.D. The Mitee Mouse II is a hand held unit, powered by compressed air and water, and is designed to clean tubes from 13 mm to 70 mm O.D. Both the Dominator and the Mitee Mouse II are easy to set up and operate. HydroDrill tube cleaning is fast and efficient. A 6 m long tube can be cleared of hard deposits inonly 30 to 90 seconds. A heavily fouled or even a completely blocked tube can be easily restored to its original I.D. in a single pass. Cleaning with HydroDrill brushes can restore a tube’s interior to as-new condition. |
HydroDrills are used to remove hard tough
deposits including: • Coke • Calcium • Sulfur • Bauxite • Alumina • Asphalt • Oxides • Polymers How They Work A HydroDrill uses a brush or drill bit mounted to the tip of a rotating Kelly Rod or Extension Rod and a water flush to remove debris. As the rod rotates, the unit pumps water through the rod to weep holes in the cleaning tool, flushing away hardened deposits as they are loosened. Safe On Tubes The HydroDrill system is designed for maximum cleaning effectiveness with no tube damage. Drill bits are sized to be 0.127 mm below the minimum tube I.D. They feature long shanks to ensure that the axis of the bit and the axis of the tube are in complete alignment. Furthermore, the bits are designed with carbide tips on the leading edge only and rounded corners to ensure no sharp edges directly impact the tube wall. The drill also rides on a thin layer of water for lubricating bearing surfaces between the bit and the tube. HydroDrills have been used repeatedly to clean process fouling on some heat exchangers over 1,000 times – with no tube damage or degradation!

Kelly Subs and Connectors
Made with both male and female threads Kelly Subs are used to adapt drill bits and brushes to both Kelly Rods and Extension Rods. To preserve the female threads on the rods it is recommended to use the hardened subs. Kelly Subs can also be used to adapt to various drill bit threads. Kelly Connectors are used to connect a short extension onto a Kelly Rod and also to connect the Extension Rods of the Mitee Mouse II

Brushes
HydroDrill brushes feature weep holes to allow the water flush to pass from the Kelly Rod or Extension Rod into the tube to flush away deposits. They are used to polish tube surfaces smooth and help keep deposits from adhering during operation. The result is extended operation between cleanings and enhanced equipment reliability. Nylon Brushes are used for removal of biofouling or thin silt like
deposits on all tube surfaces. Brass Brushes are ideal for removal of thin soft deposits or for high speed polishing of copper tube materials. Only use Stainless Steel Brush on hard tube materials for removing all types of soft tube deposits, stronger cleaning ability and durability.
Note: Custom sizes available.
Note: Brushes should be equal to or 2 mm (1/16") smaller than tube I.D.
