Coanda Natural Convectors
Coanda" Natural Convectors combine the advantages of central heating with the compactness and silence of panel radiators. The attractive casing never gets hotter than body temperature - that's why natural convectors are the natural choice when the safety of children and the elderly is considered. Ideal for the home, kindergarden, child minding centers, schools, public buildings, hospitals, aged care hostels, independent living centres, etc.
Hot water is pumped through copper tubes in the natural convector and nature does the rest. Cooler air enters through the bottom of the "Coanda" as the air flows past the finned copper tube it is heated and escapes through the top. Warm air is gently circulated throughout the room without draughts or noise. |

For temperatures other than 60°C, use the table above for correct emmissions. To calculate the obtain Mean Effective Temperature Difference (M.E.D.) use the following equation: M.E.D. = Flow + Return water temp. / 2 - Room Temp. |
