Space-Saving Design for Flexible System Integration
The STK Side Entry Stainless Steel RO Housing is engineered to meet the demands of commercial and industrial water treatment plants requiring compact and scalable solutions. Unlike end-entry models, the side port configuration allows for tighter vessel spacing and simpler "daisy-chain" plumbing, significantly reducing the overall system footprint and installation time.
Why Choose STARK Side Entry Housings?
- Optimized for Multi-Element Arrays: Available in lengths to accommodate 1, 2, 3, or 4 standard 40-inch membrane elements. This flexibility makes it ideal for medium-to-large scale systems where multiple membranes are used in series.
- Robust Seamless Construction: Manufactured from high-grade, continuous SUS304 or SUS316L stainless steel tubes. This seamless design ensures maximum structural integrity and superior corrosion resistance compared to welded or fiberglass alternatives, especially in high-pressure industrial environments.
- Sanitary Mirror Finish: Both interior and exterior surfaces undergo rigorous mechanical polishing to achieve a smooth, mirror-like finish. This not only provides a professional appearance but also prevents bacterial adhesion and facilitates easy cleaning for hygienic applications.
- Reliable High-Pressure Performance: Engineered and tested for a standard operating pressure of **300 PSI (2.0 Mpa)**, ensuring safe and reliable operation in demanding Reverse Osmosis applications.

Typical Applications
The side-entry configuration is particularly advantageous for compact and multi-stage systems in:
- Commercial RO Systems: Ideal for hotels, restaurants, and car washes where mechanical room space is limited.
- Industrial Process Water: Used in pre-treatment for boilers, cooling towers, and manufacturing processes.
- Food & Beverage Production: Ingredient water filtration requiring sanitary stainless steel construction (SS316L).
- Municipal Water Treatment: Small to medium-scale desalination or brackish water purification units.
