Fan Controller for c-13 cat

The Controller for my C-13 must be replaced.  The controller a Danfoss11163037 is no longer made and there is no replacement for it.  What do I need to do?  I have seen some discussion about using a wax controller but I do not know if there is one compatible for the C-13 nor how much it might cost.  Can anyone help advise me on what to do?

Hi I have one of the same systems on a 2005 bluebird with the Wanderlodge. the fan system I believe on the CC build c13 is a Hydrostat. the controller collects temp information in the form of a resistance output from the temp senders and then does the majic to send a pulse width signal to the hydraulic pan proportional control valve. if you measure that signal and it is 6 volts, it is actualy still 12volts but being broadcasted at the solenoid via a pulse of 50% on and off.

60 of the The Bluebirds share this hydrostatic fan drive that Eaton and CountryCoach developed for EPA requirements. We also shar in non existing fan controllers. Our systems use 24volts of pulse width to control fan speed but the idea is the same. I am building a controller to sell that can be programmed in C++ which is a common computer program. If you wish we can discuss the two fan systems. here is a fan controller I built for a customer to get things going and collect need in out effort to find the absolute best fan speeds.

here is an article from CountryCoach and Eaton about the fan system I believe you have
