    Won't box condition affect results. I wonder if circumstances can affect return on investment. What is the initial up front cost compared to conventional setup with grasslin timer and an etc. what data can I use to bring to my boss to convince him to give this a shot. Is there any concrete data.

    It absolutely will. The one I have them on has one reach in display door that is all jacked up. The torque master is broke and we have one on order, but in the meantime the door doesn't shut all the way. A lot of defrosts, although a lot of them only being 20 minutes or so.

    Setup costs all depend on how much wire you have to run, how many evaporators, and how much conduit. Pm me and maybe we can discuss it further and give you the name/phone number of the guy who I dealt with who was awesome.

    Go check out www.ke2therm.com and look for their ROI generator. Supply it with as much info as you can about whatever customer you have in mind. That will give you a reasonably close idea, but as Ryan1088 mentioned, each install has it's own set of dammits. Tread carefully when Estimating this or anything else. Good luck!

    Minimum Defrost is every 2-1/2 days. There was 3 coils in the freezer. Two coils were defrosting 2 times every 5 days. The third coil was doing all the work and defrosted 5 times in 5 days. This proves a valuable point - if a coil isn't doing any work why should it be defrosting?

    Thanks for your interest and confidence in the controller.
    Here a few comments and answers on the KE2Evap controller. Defrostmadness is correct that the controller will force itself into a defrost every 21/2 days (60 hours). This is more of a diagnostic defrost to check its calculations and make sure there have been no radical changes to the evaporator. As you can see from the screen shot, it is short and does not affect room temp very much.
    Itsiceman had a comment about where the energy savings come from and where does defrost reduction enter in to it. Yes, fewer defrosts mean that less energy is used for defrost and less compressor energy is used for re-establishing room temp. but it goes deeper than that. The control works to minimize defrosts by "consuming" frost essentially as it forms. The controller will turn off the compressor and use the fans to sublimate the frost, reclaiming the energy the compressor has used to make the frost. This is always effective and since the ice goes directly from solid to vapor it will absorb about 1300 btu/pound without actually melting into water which would be impossible in a freezer.
    The fact that the defrosts are spaced out so much indicates that almost all the frost is used for cooling, the compressor is off a lot of the time and and active defrost is not needed. Energy is saved on comp run time, fan off time, latent energy reclaim and little external heat needed for defrost.
    That also addresses defrostmadness' comment. It is not that the coils are not doing work, it is that the system uses the frost for additional cooling so defrosts are not needed very often.
    I hope that helps.

    One last comment on the IP address. Each controller has a unique IP address but they are in the 10.10.xx.xx format. 10.10. numbers are non-routable meaning they cannot be directly addressed from the internet. In a local network any browser can find them by using that address but you will not be able to see them by just typing in the 10.10.xx.xx from an external location. Just as in your home, a computer must go thru a router to get to the outside world. The KE2 controllers are connected to a router which is connected to the internet. To see the controller, browse to the router IP and use it to get to the controller IP.
    When connecting directly to the controller with a laptop or other computer, often you will need to tell the computer to look for the 10.10 number. IP addresses are like phone numbers and the 10.10 number is an area code. Many laptops must be told to look for a 10.10 area code. This is about a 30 second setup and any child can do it. In fact, it is so easy, even an adult can do it! Check the KE2 website for the bulletin on "Changing the Static IP Address".

    I had to replace a beacon 1 with a ke2, in my opinion, I think the ke2 does a better job than the original beacon, but I don't have any proof.
