Maintaining Counter Flow Closed Circuit Water
Cooling Tower For Enhanced Energy Efficiency

• 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.

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

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.
