Well, up front, I can advise you I've never installed any kind of cold start device, nor ever needed one, because where I live and have worked in Australia, I never saw anything like really cold mornings!
Maybe a little bit of thin ice in containers left outside overnight with water in them, but it was usually gone, not long after the sun came up!
However, I ran plenty of Perkins diesel engines (as well as Cat, Cummins, Komatsu, Deutz, Detroit, Toyota, and probably another half-dozen brands I've forgotten about) - and I know that Perkins supplied a simple little electric and diesel-fired intake heater that was effective in very cold starting conditions.
None of the engines I ran needed any kind of cold start assist, normally - unless they were very tired - in which case, a gasoline-soaked rag, lit up and held over the intake, usually did the trick!
However, as I see where you live, is in a region with bitterly cold Winters, I'd suggest that adapting a Perkins intake heater is probably the simplest and easiest way to solve your cold start problems.
The advantage with the Perkins intake heater is that electric current draw is reasonably low, so no major extra drain on batteries that you need for operating the starter motor.
However, you will still need to plumb in a separate relay for the Perkins intake heater. The other advantage with the Perkins intake heater is, they're cheap.
You will need to plumb in the fuel line to the intake heater, and the small diesel reservoir as well, but I'd have to opine that's not a task that's beyond the average HEF member who owns and runs engines and equipment, and who has average-to-good mechanical skills.
Here's a guy with an educational YooToob video showing the Perkins intake heater, and how it operates, and I'm sure he'd be more than happy to assist you as well.
