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

Winter 2025 Update: Since December 2022 the supply chain strictures have fortunately eased, with less stress on product delivery due dates. Our teams at YORK 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 Inertia Dynamics / Digital 70-16723-03 parts and service support, we have been able to add new lines of product and service:

Starting Q1 2025 YORK is pleased to announce additional repair and rebuild services for the automation products made by industrial controls leader Hub-City such as the 622064706 spares. Related to this we have added to our service line-up the 445TZ manufactured by Reliance and we are pleased to be able to service most Reliance systems and parts.
