SCC-C Sample Gas Cooler Operator’s Manual 

42/23-55 EN Rev. 1 

Chapter 4 

Sample Gas Cooler Shutdown and Packing 

 

Sample Gas Cooler Shutdown 

  

Step Action 

1 

Disconnect the sample gas cooler power supply. 

2 

Shut off the sample gas supply to the sample gas cooler. 

Loosen the sample gas and condensate lines from the sample gas 
cooler ports. 

3 

 

The condensate that accumulates is often acidic. Neutralize the 
condensate if necessary, and comply with relevant regulations 
on disposal. 

4 

Thoroughly purge the sample gas cooler gas paths with an inert gas. 

5 

Fully tighten the gas connections. 

Sample Gas Cooler 
Shutdown 

6 

Remove the electrical lines from the connectors. 

  

 

If the sample gas cooler is returned to ABB Service, e.g. for repair, please indicate 
which gases have been supplied to the sample gas cooler. This information is 
needed so that service personnel can take any safety precautions required for 
harmful gases. 

  

 

Make sure the sample gas cooler is free of residual moisture that can freeze if low 
temperatures are encountered during shipping and storage. 

 
Ambient temperature for storage and transportation: –25 to +60 °C
