XRi-Xwi

XRi and XWi controllers offer the optimum solution for controlling plug-in units with variable capacity compressors. The controllers, available in compact and split versions, maximize energy savings, extend appliance reliability and efficient management of the product maintenance temperature. An important feature is the reduction of plant handling costs due to reduction in reactive power demand. They are designed for plug in, open islands, cabinet with refrigeration systems, bottle and wine coolers.
