Product Overview
An alkaline protective product used for neutralisation and metal surface passivation after acidic chemical cleaning. It complements post-cleaning treatment in boilers, heat exchangers, chillers and cooling circuits, at a different stage from acidic descaling products.
Where Is Alkalen NP-100 Used?
- Neutralisation after acidic cleaning
- Post-cleaning steps in boilers and heat transfer systems
- Material-specific surface passivation
Technical Features
- Alkaline treatment for post-cleaning neutralisation and passivation.
- Applications in steam, hot-water and heating boilers and heat transfer systems.
- NP-100 SPECIAL and P-100 oil preservation products are separate variants.
Chemical Cleaning Application
1. Pre-rinsing
Rinse the system after acidic cleaning; the bulletin specifies pH 7–7.5 for pre-rinsing.
2. Neutralisation and passivation
Apply under a material-compatible post-treatment procedure. Quantity and conditions depend on circuit volume, residual acidity and technical checks.
- Packaging Options
- 35, 70 and 250 kg HDPE containers
