Question
I want to install a blower (12 or 24V) to supply cooling air to small (8KW) diesel powered generator inside tight sound-proofed enclosure. The blower should start when generator starts but continue blowing until temperature inside the enclosure drops down. This would be came as electric fan for automobile radiator. What would be good controller to use; Japanese are most available here (Thailand).

Answer
Leons,
  First, I'm an Auto Parts specialist. This question would be better suited to someone who works on Recreational Vehicles or Motor Homes but I will try to help.
  I can see a problem wanting to install a cooling fan in a sound-proofed enclosure. You need to have air flow and that cannot happen in an enclosure that has no air inlet or outlet. Air can blow but it has to circulate bringing in cool air in and blowing hot air out.
  Guessing you can work around that problem of noise, there are many companies here in America that offer thermostats that you can purchase to wire into a fan (all 12 volt) to do the job. There are companies called Hayden and Flex-A-Lite that offer such thermostats. They won't come on when the generator comes on but they can be "pre set" to come on at a certain temperature and run until the temperature drops below the predetermined setting.
  I haven't looked but I'm sure these thermostats are very available in the part of the World in which you live. I would imagine they are made in Japan, China or Taiwan. If you need any more help, just let me know.. Good luck.
