Exchangers made entirely of stainless materials, intended for systems with high sanitary standards.
The HEXONIC LUNA is a brazed plate heat exchanger made entirely of stainless materials, developed for systems with high sanitary standards. Its materially homogeneous construction delivers a high hygienic level together with strong resistance to temperature changes and corrosion.
Thanks to its all-stainless design, the LUNA can be used in heating and refrigerating systems with strict sanitary requirements. It is also a suitable solution for aggressive media, including aggressive water from water supply systems, ammonia, and systems with galvanized pipes.
Key Features
- All-stainless homogeneous design: The LUNA is made entirely of stainless materials, supporting hygienic operation and material consistency throughout the exchanger.
- Stainless LUNA brazing: The unit uses HEXONIC’s stainless LUNA brazing instead of standard copper brazing.
- High hygienic level: The product is specifically intended for systems with high sanitary standards
- Strong corrosion resistance: The exchanger is designed to resist corrosion and temperature changes over a long service life.
- Suitable for aggressive media: The live page states it can be used with aggressive water, ammonia, and systems with galvanized pipes.
- Long lifespan: Long service life is listed among the core LUNA features.
