Relevant Fields of Application

HVAC
Heating and cooling networks operate under temperature variances, vibration and continuous load. Long-term efficiency relies on corrosion resistance, joint integrity and consistent system performance.
Sport and Industrial Floor Heating
Large-scale radiant systems must deliver even heat across significant areas. Once installed, access is limited, so durability, oxygen control and long-term thermal stability matter.
Industrial Piping
Industrial systems operate under pressure, temperature fluctuation and continuous load. Performance depends on corrosion resistance, material compatibility and compliance with recognised standards.
In-Ground
In-ground systems need to perform long term under pressure, movement and changing ground conditions. Durability, joint integrity and long-term system reliability are central to performance
Non Potable & Process Water
Non-potable and process water systems still demand durability and fit-for-purpose design. Variable water quality and reuse applications require corrosion-resistant, reliable, cost-effective materials.
Radiant Heating
From residential slab heating to large-scale commercial floor systems, radiant projects demand long-term performance. Once embedded, access is limited, so compliance, oxygen control and material reliability must be right from the start.
Glycol Cooling Water
Glycol systems demand long-term thermal stability. Material compatibility, corrosion resistance and dependable flow are essential to maintaining system efficiency and protecting critical heating and cooling infrastructure.
Compressed Air
Compressed air networks run under constant pressure and mechanical stress. Corrosion resistance, seal integrity and safe long-term performance are essential.
Geothermal
Geothermal systems operate in challenging environments for decades. Materials must handle pressure, ground conditions and continuous temperature exchange without degradation.
