yes the herpstat 2 (herpstat4 and pro), the ecozone system, the herp keeper. They all do dual + zones. The herpstat 4, eco zone and herp keeper all have very advanced controls and 4 zone control and the pro has 4 zone and advanced features but not as many.

If you are looking at dual racks I am using a HS pro on mine but the ecozone has internet setting and internet monitoring plus alarms that could be a very valuable asset you pay for that feature however.
