SOP for Operation of Cooling Towers is to establish a standardized procedure for the safe and efficient operation of cooling towers, ensuring effective heat dissipation, maintaining water quality, and promoting equipment longevity.Operation of Cooling Towers

SOP for Operation of Cooling Towers

  • OBJECTIVE:
    • To lay down the procedure for operation of cooling towers installed on Terrace area of Service area
  • SCOPE:
    • This SOP is applicable to operation of cooling towers installed on Terrace area of Service area.
  • RESPONSIBILITY:
    • Technician/ Operator of Engineering Department shall be responsible for proper execution of operation as per SOP.
    • Engineering – Head shall be responsible for reviewing the SOP and for ensuring proper execution as per SOP.
  • ACCOUNTABILITY:
    • Head – Engineering shall be accountable for proper implementation of the SOP.
  • DEFINITIONS:
    • Nil
CT 04
  • PROCEDURE:
  • Pre Check to start  up cooling tower:
    • Check, the water level in the cooling tower sump it should be above the minimum water level.
    • Check that float valve is operating properly.
    • Check the fan blade and fan motor for proper working.
    • Check the strainer inlet and out let valves are opened, and bypass valve is closed.
    • Check chiller’s condenser inlet and outlet valves are opened.
    • Check the cooling tower water inlet (return from condenser) valve is opened.
    • Check the main switch of control panel, it should be ON.
    • Once in a week check the TDS level in cooling water circulation is should not be more than 2000 ppm.
    • To prevent the corrosion, scaling and microbial fouling, following chemicals are added in basin of cooling towers are as follows.

  • To start  cooling tower:
    • Start the cooling tower fan from electrical panel by pressing start (Green) push button.
    • Start the cooling tower pump from the electrical panel by pressing the start (Green) push button.
  • To stop cooling tower:
    • Stop the cooling tower fan from the electrical panel by pressing the stop (Red) push button.
    • Stop the cooling tower pump from the electrical panel by pressing the stop (Red) push button.
    • Close the all relevant in and out valve.
    • Record the activity for operation of HVAC Cooling Tower as per Format No. SOP/EN/XXXYYY. The recording should be done after every two hours, this format  is applicable in case of break down; for following parameters
