Heat dissipation systems installed in coastal areas operate in one of the most environmentally aggressive scenarios. The combination of high humidity, marine aerosols, and the constant presence of chlorides (mainly derived from sea salt) significantly accelerates corrosion phenomena.
In sectors such as oil & gas and coastal industrial facilities, this translates into:
- Reducing the useful life of equipment
- increased maintenance costs
- unscheduled plant shutdown
- thermal efficiency loss
Therefore, corrosion protection is not an optional extra, but a strategic requirement.
We protect your investment: the W-TECH philosophy
The solutions developed by W-TECH are born precisely to respond to these extreme conditions. The machines are made as standard fromMagnelis®, an innovative and environmentally sustainable alloy composed of zinc, 3.5 percent aluminum and 3 percent magnesium.
Magnesium activates aself-repair processof surface protection, ensuring continuity even on:
- cut edges
- punched areas
- Deformed surfaces during machining
Key benefits of Magnelis®
- Significantly higher corrosion resistancethan galvanized steel (salt spray test)
- Self-healing protectioneven on damaged areas
- High application flexibility
- Lower environmental impact than traditional treatments
Multilevel protection: when the environment becomes extreme
To deal with even more aggressive conditions, W-TECH integrates advanced protection systems.
B-COAT: maximum defense in the most exposed areas
TheB-COATsystem was specially developed to ensure protection of the most critical area of the machine: the water catch basin.
It consists of:
- high adhesion primer
- super durable epoxy enamel
Offers high protection against.:
- impacts and abrasions
- acids
- chlorides
- ammonia
The result is guaranteed structural integrity even under critical operating conditions.
W-COAT+: complete protection inside and out
W-COAT+treatment is a polyester powder coating applied electrostatically and fixed at high temperature.
Main features:
- High resistance to UV, chemicals and weathering
- application before assembly for full coverage
- standard RAL 9006 finish (with custom colors available)
The benefit is real:less wear, less maintenance, longer operating life, especially on cooling towers and condensers.
4Shield: the most advanced protection against corrosion
The4Shieldsystem represents W-TECH’s most advanced approach to plant durability.
It is a four-level defense structure:
- Structural steel– solid and strong base
- Magnelis®– self-repairing protection
- W-COAT+– barrier against chemical and atmospheric agents
- Elastomeric polyurethane barrier– impermeability and mechanical strength
The result
- fully protected structure
- zero infiltration
- increased operational security
- reduction of unexpected costs
- significantly longer life cycle
Conclusion: corrosion is prevented, not suffered
In extreme coastal and industrial environments, the real difference is not just the heat dissipation technology, but the ability to protect it over time.
W-TECH offers a concrete answer:systems designed to last, even where corrosion is the rule rather than the exception.
