Blygold History
PoluAl XT MB


 
Problem
 
Cooling equipment causes unhygienic problems. The cooling coil is an underestimated source of hygienic contamination. On the heat exchanger surface, one can find bacteria, yeast and molds of all strains. This often occurs when the heat exchangers and the condensation outlets of these units are not regularly cleaned and disinfected.
If they are not treated and subsequently
cleaned and disinfected, they can become a constant source of infection. Forced
ventilation of contaminated air presents a
real danger in the food industry, hospitals, care centers and even in offices. This
danger can vary from bad odor to
contamination of food.
 
 
Why use PoluAl XT MB?
 
• To prevent hygienic problems at cooling equipment
• Corrosion protection
 
 
 
 
 
Solution
 
Blygold PoluAl XT MB is a corrosion resistant coating that is developed for heat exchanger surfaces in hygienically sensitive environments. PoluAl XT MB will improve the quality of the cooled air, prevent bad odors and reduce the adhesion of pollution. The need for cleaning and disinfecting is lessened and aggressive chemicals are not required. To optimize the condition of the Blygold PoluAl XT MB treated heat exchangers, disinfecting with Blygold DEC is
recommended.
