Description
Product Overview
The TrueFit InDuct 2000 Advanced Photocatalytic Oxidation (PCO) 9″ Replacement Cell and UV Bulb is engineered to provide a high‑performance, ozone‑free solution for water purification systems that demand reliability and longevity. Constructed in our Pasadena, California facility, each unit adheres to strict EPA standards (Establishment Number 96244‑CA‑1) and is built from premium UV‑grade quartz and stainless‑steel components that resist corrosion and maintain optical clarity over thousands of operating hours. The replacement cell integrates a state‑of‑the‑art photocatalytic catalyst that works in tandem with the UV bulb to break down organic contaminants, bacteria, and viruses without generating harmful ozone. With a compact footprint of 20.5 x 4.25 x 4.25 inches and a lightweight design of just 6.4 ounces, the module fits seamlessly into existing InDuct 2000 housings, preserving the original system layout while delivering upgraded performance. The product carries the model number TFSAS‑9‑AS and is backed by a 12,000‑hour operational life, ensuring that facilities ranging from research laboratories to large‑scale industrial plants can rely on continuous, effective water treatment without frequent part replacements.

Usage
Designed for a broad spectrum of applications, the TrueFit replacement cell and UV bulb excel in environments where water quality is critical and ozone emissions must be avoided. In laboratory settings, the system provides a clean, contaminant‑free water supply for analytical instruments, cell culture, and chemical synthesis, supporting experiments that require stringent purity standards. In industrial contexts, the module is ideal for cooling tower water treatment, boiler feedwater, and process water loops, where it helps mitigate bio‑fouling, scale formation, and microbial growth without the regulatory complications associated with ozone‑based technologies. The ozone‑free design also makes the product suitable for residential and commercial building water systems, such as HVAC condensate management and potable water pre‑treatment, where occupant health and indoor air quality are paramount. Installation is straightforward for qualified HVAC technicians: the unit replaces the existing 9‑inch cell and bulb assembly, requiring only standard tools and a brief shutdown period. Once installed, the system operates silently, consuming minimal power while delivering continuous disinfection, making it a cost‑effective, low‑maintenance choice for any facility that values both performance and environmental responsibility.
