Frequently Asked Questions
• What exactly is the Cortec Boiler Egg and what's its primary purpose?
The Cortec Boiler Egg is a specially designed product created to actively scavenge oxygen and passivate metal surfaces within boilers, primarily during the crucial initial filling phase of makeup water after a period of seasonal or long-term dry layup. Its main goal is to protect against the damaging effects of oxygen pitting.
• How does the Boiler Egg function to prevent corrosion within a boiler system?
When the boiler is being refilled with water, the Boiler Egg, which comes in a water-soluble pouch, dissolves and releases its active ingredients. These ingredients then work to eliminate dissolved oxygen from the water and create a protective layer on the metal surfaces, preventing corrosion, particularly oxygen pitting, during the critical startup period when the boiler's regular chemical program isn't fully operational.
• What are the key ingredients or technologies that make the Boiler Egg effective in corrosion prevention?
The Cortec Boiler Egg utilizes a unique blend of active ingredients specifically formulated to scavenge oxygen and passivate metal. While the exact proprietary blend isn't detailed, it's designed to be highly effective in mitigating oxygen-induced corrosion.
• Is the Boiler Egg a standalone corrosion protection solution, or does it work best with other products?
While the Boiler Egg can certainly be used on its own for applications requiring oxygen scavenging and metal passivation during boiler startup, it's often recommended for use in conjunction with Cortec's Boiler Lizard. When used together, they form a comprehensive preservation kit for both dry layup and the subsequent startup phase.
• What's the significance of the Boiler Egg being "pH neutral" and "biodegradable"?
Being pH neutral means the Boiler Egg won't significantly alter the pH balance of the boiler water, which is important for maintaining system integrity and avoiding adverse chemical reactions. Its biodegradability highlights its environmentally friendly nature, breaking down naturally without leaving harmful residues.
Relevant products you may want to consider:
• When is the ideal time to apply the Cortec Boiler Egg to a boiler?
The Boiler Egg should be applied either when you're preparing a boiler for a dry layup or right at the beginning of its startup phase. This strategic timing ensures its active ingredients are released precisely when the risk of oxygen pitting is highest.
• Do I need to remove the Boiler Egg or its pouch before operating the boiler after application?
No, that's one of the fantastic benefits! There's no need to remove the product or the inner water-soluble bag. The PVA bag is designed to dissolve completely as the boiler fills with water, releasing its contents into the system.
• Where exactly should I place the Boiler Egg inside the boiler for optimal performance?
