Belzona® Saves Heat Exchanger From Costly Replacement

 
 

Industry:

Heating, Ventilation & Air Conditioning (HVAC)

 
 

Application:

Heat Exchangers (HEX)

 
 

Customer Location:

Alaska, USA

 
 

Application Date:

1983

 
 

Application Situation:

Heat exchanger covers.

 
 

Problem:

All ten heat exchangers had been replaced just one year ago. The covers were stainless steel but were welded with a carbon steel rod, setting up electrolysis. Replacements would take more than 3 months to build and a cost of downtime at $70,000.00 per day. With Belzona, all ten were rebuilt in just seven days. They were opened one year later and the heat exchangers were found to be in perfect condition.

 
 

Products:

Belzona 1311 (Ceramic R-Metal)

Belzona 1321 (Ceramic S-Metal)

 

Substrate:

Stainless Steel

 
 

Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflet HEX-2.

 
 

Belzona Facts:

The alternative was ten new heat exchangers costing over $500,000.00 plus several millions of dollars in downtime. Instead, all of the ten heat exchangers were rebuilt in seven days with Belzona, costing only $15,000.00.
