High pressure water jetting units for descaling
High-pressure water jetting units for descaling are powerful tools used in various industries to remove scale, rust, and deposits from metal surfaces, pipes, heat exchangers, and industrial equipment. By utilizing high-pressure water streams, these units effectively eliminate buildup without damaging the underlying surfaces, ensuring enhanced operational efficiency and longevity.
Whether you're in the oil & gas, steel, or power generation industries, our high-pressure water jetting units offer an efficient, cost-effective way to descale equipment.
How water jet descaling works
The high-pressure water jetting units for descaling operate by delivering extremely high-pressure water streams (up to 2800 bar) through specialized nozzles. This targeted pressure breaks up and removes scales, oxides, and other deposits that accumulate on metal surfaces and pipes, leaving them clean and operational. These units are designed for:
Equipment these units descale
Heat Exchangers: Removing scale buildup and improving heat transfer efficiency
Turbines and Industrial Equipment: Restoring performance and efficiency
Boilers and Pipes: Cleaning hard-to-reach areas with minimal downtime

Matching pressure to the scale you need to remove
Descaling jobs vary widely, from soft sludge in tanks to hard mineral scale in boiler tubes. These ranges, taken from typical applications, help you shortlist a unit.
Light scale and sludge
Around 500–1000 bar is often enough for lighter industrial descaling and loose deposits in tanks and pipes.
Heat exchanger tubes
Units in the 500–1500 bar range with the right nozzle and controlled flow are commonly used to clean tubes without damaging them.
Hard boiler and mineral scale
Tougher deposits typically call for 1000–2800 bar, chosen by scale thickness and equipment design.
Flow for the job size
Pick flow within 15–200 LPM: lower for precise tube work, higher for large surfaces and flushing out heavy debris.
Power and mounting
Electric skids for fixed plant use, diesel trailers for field work, hydraulic drive where hydraulics are already on site.
Accessories
Rotary nozzles, surface cleaners, hose reels and control panels can be added to suit the equipment being descaled.

Frequently asked questions
Straight answers to what buyers ask us most. Can’t find yours? Ask our team.
What is high pressure water jetting used for in descaling?
It removes scale, rust, sludge and hard deposits from heat exchangers, boilers, pipes, tanks, condensers and other industrial equipment. The water jet does the work, so no abrasives or harsh chemicals are needed, and the base metal is left intact when pressure and nozzle are set correctly.
What pressure range is used for descaling?
It depends on the deposit. Lighter industrial descaling often works at around 500–1000 bar. Tougher scale and heavier cleaning commonly use 1000–2800 bar, depending on the deposit type, surface condition and how clean the surface must be. Our units cover 500–2800 bar and can be customised.
Which unit suits heat exchanger descaling?
A unit in the 500–1500 bar range with the correct nozzle and controlled flow is often used for heat exchanger tubes. The exact pressure depends on how much scale there is and the tube condition. Share tube ID, length and deposit type for a recommendation.
Can water jetting remove boiler scale?
Yes. Water jetting is widely used for boiler descaling because it removes hard mineral deposits, sludge and internal build-up from boiler tubes and surfaces. Required pressure depends on scale thickness and boiler design, and higher-pressure units in our range handle the harder deposits.
How do I choose a unit for pipe and tube descaling?
Choose by pipe diameter, scale hardness and how far the deposit extends along the pipe. Internal cleaning uses specialised nozzles that propel themselves through the pipe, and pressure is selected to break the scale without harming the pipe wall. Longer runs may also need more flow.
Is diesel, electric or hydraulic power better?
Electric units suit fixed plant use where stable power is available. Diesel units are better for outdoor or mobile descaling work. Hydraulic-powered units make sense where hydraulic systems are already part of the operation, such as on certain vehicles or plant equipment.
Should I choose a trailer-mounted or skid-mounted unit?
Choose trailer-mounted if your crew moves between sites or works in the field. Choose skid-mounted for plant use, workshops and stable industrial installations where portability matters less. Both carry the same triplex plunger pump technology. Tell us where the work happens and how often the unit must move, and we will suggest the better option.
What safety features do the units have?
Our descaling units include remote operation, pressure monitoring and auto-shutdown. These protect operators and equipment, but crews should still use proper protective gear and follow your site's high pressure jetting procedures. Ask us about suitable guns, lances and hoses rated for the working pressure you choose.
What should I send for a quote?
Send the equipment to be descaled (boiler, exchanger, pipe, tank), scale type and thickness, required pressure if known, preferred flow, power source and whether you need a skid or trailer. Photos of the scale help us recommend the right unit and nozzles.
