SPX Cooling Technologies Mechanical Draft Cooling Tower Class 800 - Manual (Page 7)

Class 800 technology produces a product with
definite, predictable and measurable performance.
Extensive laboratory, university and field testing for
long-term service in various climates and circulating
water conditions has enabled us to simulate and
evaluate tower longevity and performance.
Here are a few of the advantages of this structure:
• Durability
Impervious to a broad range of corrosive
substances—immune to rot and decay.
• Fire resistant
Marley concrete counterflow cooling towers
with our standard hanging fill are Factory Mutual
approved. Sprinkler systems are not required,
saving on first cost and maintenance expense.
• Ease of construction
Local trades have many craftspeople with
bridge and building experience, and most cities
in the world have concrete mix and precast
plants. Concrete alone keeps the majority
of your cooling tower costs within the local
economy.
• Very stable
Coefficient of thermal expansion is less than
steel.
• Intermittent operation
Concrete is perfect for “cycled” cooling towers
as it naturally maintains its structural integrity,
whether wet or dry.
• Non-conductive
Reduces the hazard of electrical shock.
• Environmentally friendly
/ Concrete fits the Marley “Total Systems” approach /
