Type of nozzles for transformer deluge system

Type of nozzles for transformer deluge system

(OP)
Talking about open spray nozzles, for deluge systems, used as protection from fire exposure and controlling fires on vessels.

I´ve seen on literature from sprinkler manufacturers (Gem, Viking, etc.) that there there basically two types of open spray nozzles with filled cone patterns:
 
-nozzles has water droplets with medium velocities (these are similar to a sprinkler with an "umbrella" deflector) (Exampel Gem: D3,Viking:E),
-nozzles with velocity that go from medium to high (these are more complex and have an internal vortex deflector (Example; GEM: Mulsifyer).

From what I´ve seen, the first type is more easy to use since you can choose from several K factors and cone angles, but the other has a angles and K factor for each model and I think are more expensive and suitable to get clogged.

I want to know which are better for the protection of outdoor oil filled transformers. Any other hint or information on the selection of nozzles will be appreciated.
