Cooling Unit Blockage
When a cooling unit malfunctions due to a blockage, the boiler section may be too hot to touch and the absorber will be relatively cool. Any blockage reduces the free flow of the solutions and will inhibit or completely prevent proper operation.
Leaking Cooling Unit
If the boiler is warm and the absorber is hot this indicates that a leak has developed and the hydrogen gas has escaped. The liquid ammonia does not change to a vapor without the hydrogen gas atmosphere and circulates as a liquid.
HOT absorber tank......hydrogen gas has leaked out. You have a crack somewhere
