The skid design describes a modular construction method in which complete technical systems or system components are pre-assembled on a stable frame (the so-called skid) and delivered ready for use. The skids consist of a steel or stainless steel frame on which all relevant system components, such as pumps, valves, measurement and control technology, pipelines, tanks and control units, are compactly mounted.

This concept is used in particular in industrial water and wastewater technology, as it enables efficient, space-saving and cost-effective installation. Skid systems are often used in processes such as reverse osmosis, dosing technology, ultrafiltration, ion exchange and flotation.

Technical background to the skid design

Structure and design of a skid

A typical skid system consists of several functional components that are joined together on a frame:

1. supporting structure:

   • The frame is usually made of corrosion-resistant steel or stainless steel and optimized for industrial use.
   • It enables safe transportation and easy integration into existing systems.

2. Process technology components:

   • Pumps: For pumping water or chemicals.
   • Valves and fittings: For controlling the volume flow and pressure ratios.
   • Filter: For removing particles or impurities.
   • Pipes: Made of materials such as stainless steel, PVC or PE, depending on the chemical load.
   • Measurement and control technology: sensors for pH value, conductivity, pressure, temperature or flow rate.

3. Control unit (automation):

   • Integrated control systems (e.g. PLC) for monitoring and controlling the process.
   • Interfaces for communication with higher-level control systems (e.g. SCADA).

4. Utilities:

   • Containers for chemicals, dosing systems and connections for electricity, water or compressed air are optional.

Manufacturing process

The skid construction method comprises several steps that optimize the construction process:

1. Planning and construction:
   • CAD-supported design to precisely define the space requirements and interfaces.
   • Integration of specific customer requirements.
2. Pre-assembly:
   • All components are assembled, tested and inspected at the manufacturer's production facility.
3. Functional tests (Factory Acceptance Test, FAT):
   • Before delivery, the skids are checked for functionality in order to minimize errors.
4. Transportation and installation:
   • The finished skid is transported to the installation site, where it is installed and commissioned with minimal effort.

Advantages of the skid design

1. Modularity:

   • Skids are independent, compact units that can be easily integrated into existing systems.
   • Modular design allows flexible expansion of capacity.

2. Space saving:

   • Thanks to their compact design, skids are particularly suitable for confined spaces.
   • All components are optimally arranged to make efficient use of the available space.

3. Reduced installation effort:

   • As all components are pre-assembled, installation time on site is significantly reduced.
   • No complex piping or cabling required on site.

4. Cost efficiency:

   • Lower labor costs and shorter installation times.
   • Repeatable manufacturing processes reduce production costs.

5. High quality and reliability:

   • Pre-assembly and testing in a controlled environment ensure high product quality.
   • Reduction of sources of error during on-site assembly.

6. Easy maintenance and service:

   • All components are easily accessible, which simplifies maintenance.
   • Replacing and extending components is uncomplicated.

7. Mobility:

   • Skids can be easily transported and reused at other locations.
