An easy DIN rail mountable design makes the CR027 Series fan heater an ideal accessory for any enclosure. The CR027 maintains minimum operating temperatures in enclosures and helps to prevent failure of electronic components caused by condensation and corrosion.

To determine the required heater size follow this equation:

PH = (A x ΔT x k) - Pv
    PH = Required heating power for your application in Watts (W)
    Pv = Heating power generated by existing components (e.g. a transformer) in Watts (W)
    A = Exposed enclosure surface area square meters (m2)
    ΔT = Temperature differential between the desired minimum interior temperature and lowest possible external temperature of the enclosure in Kelvin (K), 1.8°F = 1°C = 1K
    k = Heat transmission coefficient of the enclosure material used:
        Stainless Steel: 3.7 W/m2K
        Painted Steel: 5.5 W/m2K
        Aluminum: 12 W/m2K
        Polyester/Plastic: 3.5 W/m2K
For outdoor applications it is recommended to double the heating power.
