The new X-Series of Pfannenberg cooling units feature an optimized control algorithm using inverter technology which allows for the precise adjustment of cooling power required to maintain the temperature within the enclosure. The X-Series guarantees temperature control within a tolerance of +/- 0.1K. The X-Series includes two models: the 6X1E, covering a power range from 1000W to 2800W, and the 6X2E, ranging from 2000W to 4500W. Both units are equipped with an RS 485 interface and Modbus RTU protocol. Units will be available in the standard side or surface mount as well as the recessed mount. The units are also UL certified.
