Sight Glass for industrial and marine refrigeration installations

Technical parameters

Max working pressure: 40bar g 

Applicable temperature: -50℃ ~ +150℃

Applicable medium: ammonia, fluorine, propane, etc.

LLG-A are sight glasses in ductile steel which meets the strictest requirements on industrial and marine refrigeration installations.



The range of sight glasses is based on 3 basic sight glasses:LLG-A 185,LLG-A 335 and LLG-A 740.The other standard lengths are combined by using variations of basic glass lengths.LLG-A

590,LLG-A 995,LLG-A 1145 and LLG-A 1550 are joined together by 2 basic LLG's by means ofa connector.The connector holds the two basic glasses together by means of screws and guidingpins,which ensures a rigid construction.



All sight glasses are equipped as standard with a built-in safety system(non return device).If aglass is damaged,the pressure of the refrigerant will activate the safety system and refrigerant loss will  be limited to an absolute minimum.
