Why choose glycol over water?
Advantages of Glycol:
- Cleanliness - Enclosed glycol systems are not exposed to the
typical dirt and ambient particulate of water systems.
- No Chemical Treatment - Industrial grade glycol is formulated with
anti-corrosion additives. The elimination of corrosion greatly reduces
maintenance costs.
- No Filtration - Since glycol systems are closed and dirt-free, no
sidestream or full flow filtration is required. This eliminates the costs of
filter maintenance and filtration pump power.
- Maximum Heat Transfer - Did you know that just 1/16" of scale
reduces heat transfer by 40%! By keeping all equipment in like-new condition
with no scale build-up, glycol guarantees constant peak performance and
efficiency.
Disadvantages of
Glycol:
- Cost - Glycol systems are usually slightly more expensive than
water systems. There is a one-time initial cost to fill the system with 30-40%
glycol.
- Convenience - In cooling systems where components are frequently
disconnected and reconnected, the glycol is typically captured and added back
to the system.
- Heat Transfer Efficiency - Glycol is 5-10% less efficient than
water in transferring heat. However, this is more than recouped by the
elimination of scale, dirt, and corrosion that can reduce heat
transfer!
