As per the CTI(Cooling Tower Institute) www.cti.org, - douglas fir is the main softwood used in part due to its strength. Some towers are made out of redwood and that is because of redwood's treatability(now most redwood is sapwood) and appearance.

Maple is a hardwood. The distinction between hardwood and softwood actually has to do with plant reproduction. All trees reproduce by producing seeds, but the seed structure varies. Hardwood trees are angiosperms, plants that produce seeds with some sort of covering. This might be a fruit, such as an apple, or a hard shell, such as an acorn. Softwoods, on the other hand, are gymnosperms. These plants let seeds fall to the ground as is, with no covering. Pine trees, which grow seeds in hard cones, fall into this category. In conifers like pines, these seeds are released into the wind once they mature. This spreads the plant's seed over a wider area. Most but not all softwood trees have needles , however the Maidenhair tree Ginkgo biloba is a softwood tree (gymnosperm) but it has leaves not needles. Balsa is extremely soft wood but it is classified as a hardwood (angiosperm)

I haven't heard of that one, but it could be because they are full of pine pitch which is water repellant.
