Therminol^® Information Bulletin No. 3 – Therminol Heat Transfer Fluid Filtration: How and Why

Occasionally a heat transfer fluid can become contaminated, resulting in the formation of sludge particles, or other sources of dirt can infiltrate the system. This heat transfer fluid system contamination can cause operational problems including circulation pump shaft seal leakage, valve stem wear, plugging of flow passages and sometimes fouling of heat transfer exchange surfaces.

Installation of in-system side stream filters before start up may help protect the system from solids problems. The Therminol Information Bulletin No. 3 covers the hows and whys of heat transfer fluid system filtration including:

• What Is the Dirt?
• What Filters are Used?
• Filter Installation and Operation
• Sizing the Filter
