Reverse osmosis systems demand housings that can handle extreme pressure, harsh conditions, and continuous operation without failure. Pentair’s CodeLine® series, distributed by Dutco Tennant LLC, offers a complete line of membrane housings and cartridge filtration vessels designed for commercial, municipal, and industrial applications across the GCC. From compact 4-inch units to heavy-duty 8-inch vessels, the CodeLine® range ensures reliable operation for desalination plants, utilities, and commercial water treatment systems.

The demand for such solutions continues to grow. The global RO membrane housing market was valued at about USD 2.5 to 2.8 billion in 2024–2025 and is expected to reach around USD 4.1 to 4.2 billion by 2032–2033, at a CAGR close to 7%. This growth is strongly linked to freshwater scarcity and rising investments in desalination technologies, particularly in water-stressed regions like the GCC.

Compact Design, Big Performance: CodeLine® 40E Series

When space is limited but reliability is essential, the CodeLine® 40E Series is the go-to solution. Built to house standard 4040 RO membranes, this 4-inch vessel combines durability with a convenient front-entry design.

  • Epoxy/glass composite body with UV-resistant coating
  • Front-end port for straightforward installation in tight systems
  • Suitable for commercial setups, hotels, factories, and construction sites
  • Designed to perform reliably in the GCC’s outdoor conditions

The 40E Series proves that compact systems do not have to compromise on strength.

Side-Entry Strength for High-Pressure RO: CodeLine® 80S Series

For heavy-duty plants operating at high pressures, the CodeLine® 80S Series stands out. Its side-entry design makes installation and servicing faster, while its construction ensures resilience under pressures up to 1200 PSI.

Why it’s chosen by utilities and industries:

  • Rugged epoxy/glass composite shell with polyurethane finish
  • Compatibility with 8-inch membrane elements
  • Long service cycles under industrial loads
  • Proven performance in desalination and large-scale RO plants

With desalination projects expanding worldwide, particularly in the Middle East, demand for housings like the 80S Series continues to rise as plants scale to meet municipal and industrial water supply requirements.

Proper Housing for Demanding Loads: CodeLine® 80E Series

The CodeLine® 80E Series brings dependable end-entry design to high-pressure RO systems. With its polished internal surface and strong epoxy-glass composite body, it supports heavy-duty, multi-element configurations.

Applications include:

  • Municipal water supply systems
  • High-pressure industrial RO arrays
  • Continuous-duty desalination plants

The global RO membrane market, which includes both membranes and housings, was valued at about USD 3.9 to 4 billion in 2024–2025 and is projected to exceed USD 5.1 billion by 2033 at a CAGR of 10–11%. Products like the 80E Series sit at the heart of this trend, offering the durability required for expanding municipal and industrial RO infrastructure.

Pretreatment Power with Aqualine Filters

No RO system can achieve peak performance without pretreatment. The CodeLine® Aqualine cartridge filter housing is designed to protect membranes and ensure long-term efficiency.

  • FRP housing with pleated cartridge filters
  • High-flow design for greater throughput
  • Quick-change modules to reduce service downtime
  • Proven in desalination, hospitality, healthcare, and manufacturing sectors

By extending membrane life and improving overall system reliability, Aqualine housings support the efficiency gains that are driving global adoption of advanced RO systems.

Smart Engineering in the Ecoline 40L30N

For mid-range commercial RO applications, the CodeLine® Ecoline 40L30N is a versatile and dependable choice. It combines advanced features with ease of servicing.

Technical highlights:

  • Epoxy/glass composite housing with UV-resistant finish
  • Quick Lock mechanism for faster maintenance
  • Side-entry port with reinforced locking groove for extra strength
  • Suitable for new systems or retrofit upgrades

With water sustainability now central to regulatory agendas worldwide, quick-maintenance designs like the Ecoline Series help reduce downtime, ensuring compliance with water reuse and efficiency goals.
