Multiplexed Cabinet Refrigeration Controllers
Overview

The XM600 series, designed for multiplexed cabinet management and made by Dixell S.r.l. (a part of the Emerson Climate Technologies Group), is now even more complete thanks to new important features. The main one is the auto-adaptive control of superheat that makes even easier the starting set up and increases the ability of the system to optimize the regulation in automatically according to the actual operating conditions. Very important are also the NTC probe management now compatible with CPC controllers, the addition of the R407F refrigerant with low environmental impact, the hot gas defrost for stepper valve and the backup (external) battery management that can close the valve in case of black out. All the mentioned functions are available for XM668D, XM669K, XM678D e XM679K models
