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.
