ScaleAwayGly-Cool concentrate is a high quality, food and beverage grade antifreeze coolant with additional corrosion and scale inhibitors added.
ScaleAwayGly-Cool concentrate contains non-toxic multi-metal inhibitors to protect chillers and their associated cooling systems against corrosion and scale.
ScaleAwayGly-Cool concentrate is designed for use in the food and beverage industries and for
systems where low oral toxicity is essential and is considerably less toxic than non food grade antifreeze and is labeled as "non-toxic antifreeze". It is used as
antifreeze where non food grade based antifreeze would be inappropriate, such as in food-processing systems or in water pipes in homes where incidental ingestion may
In order to maximise heat transfer properties of the system. ScaleAwayGly-Cool concentrate offers
excellent frost protection characteristics. A food grade tracer dye is added allowing it to act as a leak detector.
A bitter taste additive can also be added to ScaleAwayGly-Cool-FG concentrate to prevent human consumption where required.
ScaleAwayGly-Cool concentrate should be diluted using ultrapure, demineralised, softened water.
The HVAC applications that most commonly use ScaleAwayGly-Cool are ground source heat pumps, solar water heating systems and chilled water cooling systems.
Some of these applications require high levels of freeze protection, while others only need a lower level of burst protection as a safety measure.
Solar water heating systems also require a very high level of freeze protection as solar collectors and piping are located outside the building. Typically ScaleAwayGly-Cool
concentration in the range of 20 to 40 per cent will be required, with most applications using 30 per cent ScaleAwayGly-Cool.
Solar systems also have the unique characteristic of producing very high fluid temperatures during summer stagnation conditions. This leads to very
specialized ScaleAwayGly-Cool requirements that use special high temperature corrosion inhibitors to protect the fluid from breaking down rapidly.
If the wrong antifreeze is used in a solar water heating system, the fluid can break down and turn nasty very rapidly. This can result in plugged collectors,
blocked pumps, and in extreme situations systems that must be abandoned entirely.
There are special antifreeze products made exclusively for solar water heating systems and they are highly recommended for these types of systems.
Ground source heat pumps often use antifreeze in their earth loops. As these loops are often much deeper in the ground, they are typically not exposed to the same
kind of extreme conditions and therefore require a lower concentration of ScaleAwayGly-Cool, usually in the range 15 to 25 per cent. Fluid toxicity is
certainly an important issue in the ground source industry so therefore ScaleAwayGly-Cool is usually essential for these types of applications.
Many hydronic heating systems, especially those that incorporate radiant floor heating will utilize ScaleAwayGly-Cool to provide a level of safety against
burst pipes and the resulting damages that can occur to the building and the system. In these applications a lower concentration of ScaleAwayGly-Cool in
the range of 25 to 30 per cent is usually utilized just to provide peace of mind against bursting pipes during unoccupied periods. Commercial buildings that use
radiant floor heating systems and that may be unoccupied for periods of time are certainly candidates for this protection. Pipes that burst in a concrete slab are
a serious problem that can result in very expensive and disruptive repairs.
When antifreeze is used in the system there are certain installation, service and maintenance factors that must be considered to maintain a long reliable lifespan of
the fluid and the system components. Here are a few of the things to look out for:
- Boilers that use aluminum heat exchangers have special antifreeze requirements. Make sure you check with the boiler manufacturer
and use the correct fluid for these boilers, or you will be in for big problems down the road.
- Before installation of the ScaleAwayGly-Cool into the system, a thorough cleaning of the entire system must be done.
If this is not done properly there can be problems with sludge formation or pipe fouling after the antifreeze is added, leading to a reduced lifespan of the antifreeze and system.
Any residual dirt, debris, flux, or residual pipe oil can interact with the glycol and cause problems. A commercial pipe-cleaning agent like ScaleAwayBIO should be added to the
piping and then thoroughly flushed out with freshwater to remove any traces of the cleaning agent. Ideally the system should be blown out with air to remove any
residual water prior to adding antifreeze.
- If 100 per cent ScaleAwayGly-Cool concentrate is purchased then on-site mixing is required, and this can cause issues
if not done properly.
When mixing antifreeze on-site with water it is highly recommended that only distilled or de-ionized water be used.
Fresh water directly out of the tap often contains calcium, magnesium, and chlorides and when these come in contact with the ScaleAwayGly-Cool inhibitors, they often create
problems with sludge and fouling. Finally after mixing, check the concentration with a refractometer to ensure the concentration is correct.
- Once the system is charged with ScaleAwayGly-Cool, proper air elimination is critical for antifreeze systems. Air that
becomes trapped in a antifreeze water mixture is especially hard to separate. Air pockets or frothing can result when the system pump is activated, which often leads to many
frustrations during and after the commissioning process. A good quality micro bubble air eliminator is highly recommended for any system containing antifreeze.
- Different brands or types of antifreezes should never be mixed, due to the different corrosion inhibitors used by different
manufacturers. If topping up an existing system, only use the same brand that was originally installed. By only usingScaleAwayGly-Cool you are assured of
no cross contamination in your future maintenence schedule for your HVAC system.
- When the system is operational, periodic testing of the antifreeze must be done to ensure that it is still suitable for use and
providing the correct level of freeze protection. It is not unusual for something to go wrong in a system such as a leak or system maintenance, and the system
ends up getting topped up with freshwater. This will resulting in a diluted antifreeze concentration and a lack of freeze protection. Burst pipes or frozen solar
collectors can often be the result of this problem.
Typically an annual check-up will include verification of the antifreeze concentration with a refractometer, and a
check of the antifreeze pH level using a pH meter. antifreeze that has gone bad typically will have a low pH level, which if left unchecked, will start to corrode
the metal components in the system. Usually when the pH level is too low the antifreeze must be drained, the system flushed and recharged with
new ScaleAwayGly-Cool. You are welcome to send a 500ml sample of your coolant to Industrial Piping Solutions for analysis and recommendations for
future coolant protection.
The management of inhibited antifreeze in the waterside of your cooling equipment and associated piping is of paramount importance for the efficiency and lifespan
of your equipment.
