COOLER CONNECTION TYPES
Standard chilled liquid connections on all coolers* are of the Victaulic type as shown below:
Flanged Cooler Connections as shown below are available as an option and should be specified with the equipment
order:
WATER REQUIREMENTS
Coolers used in these units are made of carbon steel, copper and brass and are suitable for operation with well
maintained water systems. Using unclean and untreated water may result in scale and deposit formation causing
reduced cooler efficiency or heat transfer and corrosion or pitting leading to possible equipment damage. The more
scale forming material and suspended solids in the system water, the greater the chances of scale and deposit
formation and fouling. These include calcium, magnesium, biological growth (algae, fungi and bacteria), dirt, silt, clays,
organic contaminants (oils), silica, etc. which should be kept to the minimum to retard scale and deposit formation. In
order to prevent corrosion and pitting, the pH value of the water flowing through the cooler must be kept between 7
and 8.5.
ZAMIL recommends that a water treatment specialist is consulted to provide and maintain water treatment, this is
particularly critical with glycol systems.
Using unclean and untreated water may result in reduced unit performance and
equipment damage.
