OXYLOCK®

Advanced adsorption-redox media for dissolved-oxygen reduction

Oxygen-Control Technology

Remove dissolved oxygen / Protect water infrastructure

OXYLOCK® is a granular adsorption-redox treatment medium developed to reduce dissolved oxygen in industrial water systems without continuous dosing of conventional oxygen-scavenger chemicals.

Dissolved oxygen is a major contributor to corrosion in boilers, pipelines, heat exchangers, condensate systems and industrial process-water equipment. When oxygen reaches susceptible metal surfaces, it participates in electrochemical reactions that can cause localized attack, pitting and premature equipment failure. OXYLOCK® uses a proprietary framework matrix containing adsorption sites and electrochemically active structures. Water passes through a packed media bed where dissolved oxygen is captured or chemically transformed within the active framework. The technology is intended to reduce dependence on hydrazine, sulfite, carbohydrazide, DEHA and other conventional oxygen-scavenger programs. OXYLOCK® can be integrated into upflow or downflow pressure-vessel systems for continuous industrial operation.

OXYLOCK Introduction

One oxygen-control media.
Multiple critical applications.

OXYLOCK® is intended for systems where dissolved oxygen contributes to corrosion, oxidation or process instability. Application suitability must be confirmed using feed-water chemistry, temperature, pressure and target dissolved-oxygen concentration.

Steam Boilers

Dissolved-oxygen reduction in boiler makeup and feedwater treatment.

Power Plants

Protection of steam-cycle, condensate and auxiliary water equipment.

Industrial Process Water

Oxygen control for pipelines, tanks, heat exchangers and process-water circuits.

Oil and Gas Injection Systems

Reduction of oxygen-related corrosion and microbiological risk in injection water.

Heating and Cooling Systems

Oxygen reduction in closed-loop heating, district-energy and cooling circuits.

Semiconductor Manufacturing

Dissolved-oxygen control for sensitive process and high-purity water applications.

Four oxygen-control mechanisms inside one media

OA

High-surface-area oxygen adsorption

The framework matrix provides extensive internal surface area and multiple active sites for contacting and retaining dissolved oxygen from the water phase.

RF

Internal electrochemical activity

Anodic and cathodic functional regions are intended to support electron-transfer reactions that transform captured oxygen into more stable bound species.

OL

Oxygen stabilization within the media

Captured oxygen is retained or reacted within the active framework to limit its return to the treated-water stream before media breakthrough.

AG

Low-oxygen corrosion protection

Reducing dissolved oxygen decreases the cathodic oxygen-reduction reaction responsible for many forms of corrosion in susceptible water systems.

Advanced framework technology for dissolved-oxygen reduction

OXYLOCK® combines molecular adsorption with electrochemical functionality in a packed-bed treatment medium designed to reduce dissolved oxygen without continuous chemical injection.

  • Framework-Based Adsorption – Microporous structures provide internal surface area for dissolved-oxygen capture.
  • Anodic and Cathodic Sites – Functional regions within the media are described as creating an internal electrochemical environment.
  • Oxygen Transformation – Captured oxygen may participate in reduction reactions and become incorporated into stable surface or framework-bound species.
  • External Power Not Required – The media is described as operating through its internal chemical and electrochemical potential rather than an externally powered electrode system.

Contact Support
What is OXYLOCK®?
OXYLOCK® is a granular adsorption-redox treatment medium developed to reduce dissolved oxygen in industrial water without continuous dosing of traditional oxygen-scavenger chemicals.
Why is dissolved oxygen harmful?
Oxygen participates in electrochemical corrosion reactions that can cause pitting, oxidation and premature failure of boilers, pipelines, heat exchangers and other metal equipment.
How does OXYLOCK® reduce dissolved oxygen?
The brochure describes a porous framework that adsorbs oxygen and electrochemically active regions that convert it into stable bound forms.
Does OXYLOCK® require electricity?
The media reaction does not require an external electrical supply. Pumps, control valves, instrumentation and dissolved-oxygen analyzers may still require power.
Is OXYLOCK® completely chemical-free?
It operates without continuous dosing of conventional oxygen-scavenger chemicals. However, the media itself is a chemically active material, so “no continuous chemical dosing” is more accurate.
Can OXYLOCK® replace hydrazine or sulfite treatment?
It may reduce or replace scavenger dosing in a validated application. The decision must be based on dissolved-oxygen targets, boiler pressure, water chemistry and regulatory requirements.
What does “near-zero dissolved oxygen” mean?
The brochure does not specify a numerical concentration. The website should define this in µg/L or ppb and identify the testing method and operating conditions.
What is Anoxic Passivation?
It is the brochure’s term for system protection under low-oxygen conditions. More precisely, reducing oxygen lowers the rate of oxygen-driven corrosion but does not guarantee complete corrosion prevention.
Can OXYLOCK® operate in upflow and downflow systems?
Yes. The brochure lists both arrangements. Vessel internals, media-retention devices, freeboard and hydraulic conditions must match the selected configuration.
How do operators know when the media is exhausted?
Continuous or routine dissolved-oxygen measurement before and after the vessel should identify breakthrough. A defined replacement or regeneration criterion is required.
Does OXYLOCK® require backwashing?
The brochure provides a backwash velocity of 10–20 m/h. Backwashing may be needed to remove solids and restore hydraulic performance, but it does not necessarily restore exhausted oxygen capacity.
Does OXYLOCK® eliminate all corrosion?
No single oxygen-removal process can guarantee zero corrosion. Carbon dioxide, chlorides, pH, temperature, microbiology, flow and metallurgy must also be controlled.
