Hi and welcome to our Website. My Name is Maurice Coates and I am the majority shareholder in, and founder of, Sema Ltd.
Our core business is manufacturing variable speed milk, water, vacuum and effluent pump controllers in all sizes up to 250kw.
If you would like to talk to me or one of our team about our products please contact us using the details given on the 'Contacts' page.
In as few words as I can possibly cut it down to here are the principles that guide us here at Sema:
One final word: The rural environment where our controllers are installed is wet and has bad power. We design our controllers to be able to run in this environment.
At the time of writing this (May 2018) we have over 1500 controllers operating on Dairy Farms only three of them have ever failed because of power issues (They have all been severe power events, lightning strikes etc.) and none have ever failed due to moisture problems.
Final, final word: If you buy one of our products I really hope that you like it because it's designed to last for a long, long time!!
What's in a name? From time to time I get asked where the name Sema came from. Sema is the result of my partner Senga (old Scottish name) and I spending a wet Sunday afternoon doodling on pieces of paper as we tried to come up with a suitable name for our new business. Eventually we settled on using the first two letters from both our names SEnga and MAurice. We didn't know at the time about it's connection to the automotive world nor that it appears to mean something in the Thai language?! Our Sema is 100% a NZ owned and operated business and has no connection to any other Sema's.
