During the training of northern customers about the after-sales
technical service of water chiller, S&A has found a universal
phenomenon when we`re chatting with the customers: In winter, in order
to prevent the cooling water in the chiller from being frozen, most of
the customers will add alcohol into the water chiller to prevent the
freezing.
In general case, S&A does not suggest customers adding alcohol in
the water chiller. Instead, we`d like to recommend the customers to use
antifreeze. Then what`s the difference between alcohol and antifreeze?
With the ingredient of ethanol, alcohol volatilizes quickly, which
would lead to a decrease in anti-freezing capability. Moreover, as an
inflammable and plosive substance, alcohol has stronger corrosivity than
antifreeze. Actually with the ingredient of ethanediol, antifreeze has
the characteristics of high boiling point and low freezing point, which
leads to low volatility.
During the selection of antifreeze, try to choose those big brands,
which are always better and safer. It would be more proper to control
the anti-freezing temperature within a range from -20℃ to 0℃. We don`t
suggest those brands, whose anti-freezing temperature is between -40℃
and -20℃. This is because that the stronger the temperature is, the
higher the corrosive property will be, which would lead to a larger
damage to water chiller. Then please make the dilution according to the
instruction for the use of antifreeze, when the customer would like to
add the antifreeze.
If the customer still has any problem, please consult the after-sales department of S&A Chiller.
Thank you so much for your support and trust in S&A. All of
theS&A water chillers have passed the ISO, CE, RoHS and REACH
certification with the warranty period having been extended to 2 years.
