LG ABSORPTION CHILLER
Feature & Benefits
High Reliable Stainless Steel Tube
For product reliability, cooling water tubes in absorber & condenser
should be protected from corrosive environment.
Specially designed stainless steel(STS) tube has much lower
corrosiveness compared to copper tube.
Also, it achieved powerful heat transfer performance which is
nearly same as copper tube’s performance
