is the AquaEuro APEX chiller compatible w/ apex? & what is the difference from the regular chiller?

Its time to upgrade my chiller and I've been using an AquaEuro for some time. I'm also getting an APEX EL.

While shopping I notice AquaEuro has 2 versions of their chillers. The typical chiller and an APEX chiller. The apex chiller seems to be a stronger build but I also assumed it had features that made it better for apex-controller owners.... until I read the Q&A on their site:

"Q. My chiller display is showing a higher temperature than my Apex Controller?

A. We do not recommend using an Apex controller with our chillers. Our units already have an integrated digital controller."

Keeping a consistent temp is one of my top priorities and I don't want to get a chiller that doesn't play nice with a controller and I definitely don't want to get a chiller that is branded in a way that is meant to confuse consumers.

Am I wearing crazy-pants? Can anyone give me a rundown of the AquaEuro differences and/or a chiller brand that would work better with an APEX controller?

Any help is appreciated, thanks.

There is Apex and there is Apex. APEX Technologies is a French company - specialists on cabinet air conditioners and fluid coolers. It is founded back in 1997 and the name Apex on a controller from Neptun Systems was introduced in 2009 - so the question is - how is confusing how

But the most important thing is that compressor driven water chillers is very difficult to use together with a controller. In order to work well and have a decent time of living - the compressor need to run at least 1/2 an hour or more in every run and have a rather long off time. They works best if they work in a continuous mode. To protect the chiller - rather large hysteris values is needed - often plus - minus 1.5 - 2 degree C. This means that there is some problems to have a very stable temperature in the aquaria.

However - there is techniques based on other technical constructions (Peltier-technology) that make it possible with a very constant temperature in our tanks and are suitable for controllers. However - I do not think this brand will work with controllers made by Neptune System - but there can be others out there
