Application

Condensation Control for Electrical Cabinets

Temperature changes can take cabinet surfaces below the local dew point, creating moisture on insulation, metalwork and internal components.

The challenge

Why this equipment needs a defined material evaluation.

Condensation depends on temperature, humidity, ventilation and thermal bridges rather than humidity alone.

The coating location must be selected around live components, clearances, access and maintenance.

A surface treatment complements enclosure, sealing, drainage, ventilation and heating controls; it does not replace them.

Relevant DSAN materials

Connect the application to available products.

DSAN-S2001-(II) changes how condensed water wets a treated surface; it does not stop condensation from forming. Review the cabinet design, substrate, voltage environment and existing moisture controls before application.

Key evaluation parameters

Define the test condition before comparing materials.

The table separates the parameter to evaluate from the value or project condition that still needs confirmation.

ParameterWhy it mattersCurrent value / status

Technical questions to confirm

Questions an engineer should answer before selection.

Where does condensation first appear?

Provide photographs or a cabinet layout showing affected surfaces, components, seals, vents and thermal bridges.

What temperature and humidity cycle occurs?

Record internal and external temperature, relative humidity, duty cycle and any heater or ventilation operation.

Which surfaces may be coated safely?

The equipment owner must identify permitted substrates, clearances, outage requirements and application controls.
