Cooling Tower For Enhanced Energy Efficiency
  • Introduction of Closed Circuit Cooling Tower
  • Maintenance is important
  • Closed Circuit Cooling Towers are neglected
    Why?
  • Inspection of Closed Circuit water pumps
  • Prevention against freezing of cooling towers

Introduction of Closed Circuit Cooling Tower
  • Closed circuit cooling tower is an evaporative
    piece of equipment that has two separate fluid
    circuits. The one is an external circuit where
    water is exposed to the atmosphere and the other
    is an internal circuit in which fluid circulates
    inside the tubes of the coil bundle to get cool
    down. In a counter flow closed circuit water
    cooling tower, the air enters at the tower base,
    flows upward and interfaces counter with the
    falling hot water.

Maintenance is important
  • Maintenance is an important aspect that should be
    taken seriously if you really want your cooling
    tower to perform in most efficient way. Water
    treatment comes second after maintenance and also
    affects the life and energy efficient operation
    of the cooling tower. Maintenance and water
    treatment are the most overlooked regimens of
    cooling tower operation and most users ignore
    their cooling towers components in the
    mechanical system.

Why These Cooling Towers Are Being Neglected?
  • There are two reasons behind ignorance-
  • Remotely located and difficulty in access
  • Limited maintenance resources
  • Training
  • People
  • Budgets
  • Cooling towers offer evaporative cooling for
    several types of systems. The certain application
    will determine the type of cooling tower that is
    best suited for a desired project.

How To Inspect For Closed Circuit Water
Pumps?
  • You need to check the seals and free rotation of
    shaft every month. You need to lubricate bearings
    as per the motor manufacturer guidelines.
  • You should know that leaking seals are expensive
    with lost water and treatment chemicals. To treat
    heat transfer surface, you need to clean the
    bio-fouling with professional assistance.
    Cleaning of heavy scale or bio-fouling is not as
    easy as it seems. If you perform cleaning without
    experience or professional help, the fill or coil
    get damaged in the process.

8
Prevention against freezing of cooling towers
  • You can also prevent freezing and costly ice
    damage before the arrival of winters by-
  • Checking heat tracing and insulation on drains,
    make-up, and circulating water lines.
  • Test basin controls and heaters
  • Charge system coils with glycol or drain
    completely
  • Test operation
  • Never run fans with pumps off
  • Keep a heat load on tower
  • Schedule regular defrost cycles

9
Prevention against freezing of cooling towers
  • You can call your counter flow closed circuit
    water cooling tower manufacturer and ask for
    simple guidelines to maintain and sustain health
    of your cooling tower equipment.
