LLG

LLG are sight glasses in ductile steel which meets the strictest requirements on industrial and marine refrigeration installations. The sight glasses are offered in 3 different versions: with welding nipples (LLG); with stop valves equipped with caps (LLG S) and with stop valves and sight adapter in acrylic glass ready for insulation on site (LLG SF). LLG produce sufficient flow areas to secure the highest possible degree of synchronous operation, and have a specially hardened reflection glass for quick reading. The front and the base frame are mounted together from the front with countersunk allen screws. This ensures easy insulation on site as well as easy inspection and service, if any.All sight glasses are equipped as standard with a built-in safety system (non return device). If a glass is damaged, the pressure of the refrigerant will activate the safety system and refrigerant loss will be limited to an absolute minimum
