Custom solutions

Innovative, custom made products

DERC Salotech is well known and respected for its custom made solutions and products for the high pressure water jetting industry.

Through the combination of experience, engineering skills and listening to our customers, we have achieved to turn good ideas into innovative systems and solutions. Our ideas can be a complete new product or a combination of existing techniques brought together in one new system.

All we manufacture is designed in our engineering department, produced and/or assembled in our workshop and delivered with the right documentation and CE-marking. To give you an idea about the problems we have solved, please see the examples below. 

Coil Cleaner

Problem
Eliminating manual water jetting for cleaning excentric heating coils of MDI reactor. Improvement of health and safety and shorter cleaning period.

Solution
The solution is an air driven automatic coil cleaner, which can be completely operated on a safe distance. Maximum cleaning result in a much faster time frame with optimum health and safety features for the operator.

The coils can be installed on the rollers of the machine with a crane and connected to the excentric drive mechanism to rotate the coils in an easy way. For cleaning we used an air powered high pressure swivel with a special configured 2-arm jet head. This cleaning head moved along the coil in an automatic way, cleaning the coil with a high pressure pump at 1000 bar & 130 l/min.

Inside Pipe (tunnel) Cleaner and Tube Chain Crawler

Problem
Paint removal from the in and outside of pipes with diameters of 1,80 and 3 meter. The pipes supplied a power plant and were running down from a mountain into the power plant. The pipes had paint with asbestos and were sometimes on a slope of 70 degrees.

Solution
For removing the paint on the inside of the pipe we delivered a so called tunnel cleaner. This tunnel cleaner was a stainless steel carriage which drives on wheels into the pipe. To ensure it stayed into the center of the pipe various extra guides were used.

The cleaning was done by 2 or 4 ultra high pressure cleaning heads (StoneAge Barracuda), mounted on the end of rotating air-engine-driven arms. The Barracuda's itself rotate on water pressure and removed the paint from the inside of the pipe.

The supply of the high pressure water for this project came from 2 high pressure pumps. They produced a total flow of 36 l/min at 2500 bar. The high pressure water was transported from the pumps to the tunnel cleaner with an NW13 2500 SPIR STAR® hose to minimize the pressure drop over the 700 meter long pipe line. For changing the water line in a rotating movement by the air engine we used an high pressure swivel.
