Winter 2024 & 2025 Q1 Developments in Industrial Automation - expanded product offering and diagnostic and repair services at YorkXPS

Winter 2025 Update: Since December 2023 the supply chain strictures have fortunately eased, with less stress on product delivery due dates. Our teams at YORK XPS have been able to ramp up our service response times with expedited shipment schedules back to normal, providing replacement parts and services following normal response times. Our departments are now working on near-normal production levels and our delivery and service schedules back to regular operation levels. In addition to the Keystone 121-963-390-777-013 parts and service support, we have been able to add new lines of product and service:

Related to this we have added to our service line-up the 2401300450 manufactured by Ktron and we are pleased to be able to service most Ktron systems and parts.
