Engineering guides

Engineering guides for cabinet climate-control decisions

Use these guides to understand inputs, tradeoffs and RFQ preparation before choosing a product family.

Final model selection, certificates, IP rating, replacement compatibility and thermal performance should be checked against the exact cabinet conditions and latest supplier documents.

Turn engineering notes into quote inputs

Use guides to prepare dimensions, heat load, humidity risk, voltage and replacement details before the supplier quote.

How to Size an Enclosure Cooling Fan

Start with heat load, ambient temperature, target internal temperature and airflow path before choosing fan size.

Estimate heat loadSet target cabinet temperature

How to Calculate Cabinet Heater Wattage

Heater wattage depends on cabinet surface area, temperature difference, installation condition and condensation goal.

Measure cabinet dimensionsChoose installation condition

How to Prevent Condensation in Electrical Cabinets

Condensation control is a humidity and temperature problem, not only a fan selection problem.

Identify humidity causeCheck temperature swing

Fan Filter vs Axial Fan vs Top-Mounted Fan

Use the cabinet layout, filtration need, service access and airflow direction to choose the product family.

Map inlet and outletCheck dust level

AC vs DC vs EC Axial Fans

Voltage supply, control requirement, efficiency target and signal options drive the fan motor choice.

Confirm supply voltageCheck control signal need

Thermostat vs Hygrostat

Thermostats respond to temperature; hygrostats respond to humidity.
