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.
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
- 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.
| Sr. No. | Chemical Code | Schedule | Cooling Tower – 1 (for HVAC Chiller) Dose | Cooling Tower – 2 (for HVAC Chiller) Dose | Cooling Tower – 3 (for Lyophilizer Chiller) Dose |
| 1 | MAXTREAT2715 | Daily | 300 gm | 300 gm | 150 gm |
| 2 | MAXTREAT 606 | Alternate Week | 1 Kg | 1 Kg | 750 gm |
| 3 | MAXTREAT 608 | Alternate Week | 1 Kg | 1 Kg | 750 gm |
- 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
