Carbon Footprint

Modern chiller systems are designed to operate with little or no fouling on condenser tubes. A layer of calcium carbonate scale 1/16" thick on the condenser tubes of a high efficiency centrifugal chiller negatively impacts electrical consumption by 14%.

Biofilm has an even greater effect. Defined as a slimy substance formed on heat transfer surfaces by water-borne bacteria, is four to five times more insulating than calcium carbonate scale. A biofilm layer 1/16" thick increases electrical usage by as much as 35% and can cause shutdown of the equipment.

Electronic, magnetic and other non-chemical water treatment devices work by causing the precipitation of calcium carbonate.  This results in scale formation on condenser tubes, increased electrical usage and an expanded carbon footprint. When these devices are used without a biocide, the resulting biofilm exacerbates the problem.

Poorly maintained or inferior cooling water chemical treatment progrmas also lead to foluing by scale and biofilm.  This produces the same negative environmental and economic results as the non-chemical devices.  Our Green Program, with state-of-the-art technology, provides optimal conditions for the condenser tubes and the entire system.  This allows chiller systems to operate at maximum efficiency with a minimal carbon footprint.

Within the next decade, it is estimated that as many as 40 states will see water shortages in at least some areas. Water Recycling and Reuse helps protect this precious resouce as well as offer finanical savings.


What's New

Lab Test Tubes

International Chemtex enhances its Loop Protector Program with two new products. LoopGuard 265 and 266 provide the latest in corrosion inhibitor technology employing film forming amines for protection of multi-metal closed hot and chilled loops. They are designed for use where high pH issues are a problem. These filming amines provide protection on copper, mild steel, stainless steel and aluminum, as well as other metals. This email address is being protected from spambots.
