Dwyer Omega – HVL031 Series Horizontal Compact Enclosure Fan Heater up to 400 W
Product Code: HVL031
Manufacturer: Dwyer Omega
To determine the required heater size follow this equation:
PH = (A x
ΔT x k) – PvPv = 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.
