Cooling and air-conditioning pipework
Condensation attacks from the outside. Glycol tests from within. Stainless steel resists from both sides.
TAVINOX PRESS is a stainless steel press-fit system certified for chilled water systems. Compatible with water/glycol mixtures up to 50/50.
Why stainless steel for cooling pipework
Cooling places specific demands on piping. External surface condensation causes corrosion in conventional materials.
Resistance to external condensation
Stainless steel does not corrode on the surface or at points of damaged insulation. A common problem with steel pipework in cooling applications.
Universal temperature range
One material for both heating and cooling modes. Stainless steel handles both without loss of properties, ideal for reversible heat pumps.
No corrosion inside or outside
Stainless steel resists both the medium and the surrounding environment simultaneously, unlike carbon steel which requires protection from both sides.
Inert to glycol mixtures
Stainless steel does not react with water/glycol mixtures even upon their degradation, unlike carbon steel where glycol can cause corrosion.
Long-term flow stability
The smooth internal surface, free of corrosion deposits, maintains design flow rates and pressure losses throughout the service life.
Leak-tightness
Correctly pressed joints minimise the risk of micro-leaks which, in conventional joints, cause condensation damage to building structures.

TAVINOX PRESS Technical Manual
includes sections such as:
- Cooling systems — application overview
- Glycol mixtures — compatibility
- Protection against condensation
- Installation in cooling circuits
- Reversible heat pumps — recommendations
“Cooling systems suffer from corrosion from the outside even before from the inside. Stainless steel eliminates this in both cases.”
Choosing stainless steel piping for cooling distribution reduces the risk of condensation-related failures and extends the lifetime of the entire system.
