NSD tupH (NORD severe duty, tough pH) is a surface treatment process that is an excellent alternative for multi-layer paintings and stainless steel, perfectly suited for NORD aluminium products with smooth surfaces. The treatment protects in all applications where highly-corrosive environmental conditions are present.
- Especially suitable for the food & beverages, chemical and pharma industries, as NSD tupH protects assets against aggressive detergents used in wash-down processes.
- Base layer of coating permanently enters aluminium surfaces, enabling long-standing protection.
- Free from chromates.
- No flaking, unlike with painted assets.
- Easy to clean.
- Resistant to both acids and alkalis.
- Tested in a certified Ecolab® laboratory for resistance against hot water spray (38-45°C), foaming with cleaning agents, and high-pressure cleaning.
- Approval in the food sector according to FDA Title 21 CFR 175.300.
- Aluminium has an excellent thermal conductivity and thus a high power density versus stainless steel.
- IP69K washdown geared motors with NSD tupH are now available in IE5+ efficiency.
