Our Preventative Maintenance Jack Program will ensure your equipment is operating at manufacturer’s specifications and that your service costs are predictable. While most people understand that regularly scheduled service will extend the life of the equipment as well as reduce the total cost of ownership, managing the process can be difficult.
Calumet Chicago has developed a program designed to make the process easy, affordable and effective. The effects of unexpected downtime are realized far beyond the repair cost of the equipment. Minimizing unexpected downtime increases profitable uptime.
