Water Treatment Vessel Retrofit Solutions 

Upgrade performance. Reduce downtime. Extend system life. 

Colorado Air Filter specializes in retrofit water treatment vessel solutions that help facilities modernize existing systems without the cost or disruption of full replacement. Whether you’re dealing with obsolete housings, poor filtration performance, or increasing maintenance demands, we provide drop‑in upgrades and custom retrofit options designed to fit your current infrastructure. 

Extend the Life of Existing Water Systems 

Many facilities operate water filtration systems that are structurally sound but no longer meet performance, efficiency, or maintenance expectations. Our retrofit solutions allow you to: 

• Improve filtration efficiency and water quality 
• Reduce pressure drop and energy consumption 
• Minimize maintenance time and consumable costs 
• Maintain operational continuity during upgrades 

Retrofits are ideal for cooling towers, chilled water loops, and process water systems where downtime is costly and space is limited. 

Retrofit Vessel & Housing Options 

Colorado Air Filter provides retrofit solutions for bag and cartridge filter housings, including: 

• Replacement or upgraded single-and multi-bag housings 
• Conversion from bag to cartridge filtration for improved efficiency 
• Duplex housing retrofits for continuous operation during changeouts 
• Carbon steel and 316 stainless steel construction options 
• Compatibility with existing piping, flanges, and footprints 

Our team evaluates your current setup to recommend upgrades that minimize rework and installation time. 

Filter Media Upgrades Without Vessel Replacement 

In many cases, system performance can be significantly improved by upgrading filtration media alone.

Retrofit Media Options: 

• Polypropylene, polyester, nylon 
• Meltblown and pleated cartridges 
• Filtration from 1–200 microns 

Upgrading media can: 

• Increase dirt-holding capacity 
• Improve particulate capture 
• Extend service intervals 
• Lower overall operating costs 

We match filter elements to your existing vessel geometry and operating conditions. 

Common Retrofit Applications 

Our water treatment retrofit solutions are commonly applied in: 

• Aging cooling tower filtration systems 
• Chilled water and HVAC loops 
• Industrial process water systems 
• Commercial plant utilities and mechanical rooms 
• Facilities with discontinued or hard-to-source housings 

Whether your challenge is performance, availability, or compliance, we help modernize systems while keeping infrastructure intact. 

Trusted Manufacturers & Compatible Solutions 

We work with industry-leading suppliers to ensure retrofit compatibility and performance, including: 

• 3M
