Nordic Green Products delivers a complete maintenance process tailored for Hydroniq’s Rack Coolers and Pleat Heat Exchangers. Our cleaning solutions ensure reliable performance and extended service life for hydronic systems in offshore, maritime, and i

### System Access & Dismantling

We dismantle coolers, filters, and floor plates to access critical cooling components. Units are safely lifted and prepared for cleaning.

### Chemical Cleaning with Rack Cleaner

We use **NGP Rack Cleaner**, a **biodegradable, non-toxic cleaning agent** specifically developed for Hydroniq’s **Rack, Pleat, and Tube Coolers**. This powerful cleaner is effective against:

**Marine growth**\

- **Rust and oxides**
- **Lime and salts**
- **Algae and biofilm**

Rack Cleaner contains a balanced formulation of **citric acid** and **phosphoric acid**, designed to loosen and dissolve deposits without damaging sensitive materials. It is **safe for marine discharge**, **easily water-soluble**, and does **not contain PBT/vPvB substances**.

### High-Pressure Washing

After chemical loosening, coolers are thoroughly cleaned with HP water to remove all residue. Visual inspections ensure complete contaminant removal.

### Sea Chest Cleaning

We clean the sea chest housing the coolers, restoring system flow and preventing future buildup.

### Reassembly & Torque Verification

Units are reinstalled with cleaned gaskets and torque-checked to specifications. All connections are re-secured to ensure leak-free operation.
