description and use

Spectrus NX1164 is a proprietary, water based blend of non-oxidising biocides which is used to control microbial populations in open evaporative cooling systems.

Control of microbial populations in cooling systems is essential in order to prevent biofouling. Biofouling in heat exchangers and cooling tower fill reduces heat transfer efficiency leading to higher energy costs. Biofouling can also damage equipment through microbiologically influenced corrosion (MIC) and force unscheduled shutdowns, or extended turnarounds, resulting in lost production.

Biofouling in cooling system can provide an ideal environment for proliferation of Legionella bacteria, the cause of Legionnaires disease. However, chemical treatment alone will not be effective in reducing health hazards associated with Legionella bacteria. System design, location, maintenance practices and awareness of personnel are essential elements of a successful risk reduction programme.

typical applications

Spectrus NX1164 is typically used on an intermittent basis, and may be used in a programme which includes oxidising biocides.

Spectrus NX1164 is applied as a disinfectant, fungicide and/or slimicide for commercial and industrial recirculating cooling water systems,

treatment and feeding requirements

Proper treatment levels and frequency of addition of Spectrus NX1164 depend on many factors, such as system cleanliness, microbial species, nutrient concentration, system half-life, and conditions particular to a given installation. The product should be used in accordance with control procedures that GE establishes for a specific application.
