TLC Total Lifecycle Care®
Busy engineers can easily lose track of their heat transfer fluid. It’s not something you deal with frequently or have necessarily been trained on. And without standard monitoring procedures, fluid history can be lost when people change jobs. Planning suffers, yet you must keep plants running, meet production schedules, and assure product yield and quality without unforeseen interruption––all on a tight budget. It’s a lot to ask.

The TLC Total Lifecycle Care® program from Eastman is designed to support Marlotherm® throughout their systems' life cycle. This comprehensive program includes sample analysis, system design support, operational training, safety awareness training, start-up assistance, flush and refill fluids, and our fluid trade-in program.
