Danfoss A/S Liquid Level Site Glasses LLG

LLG are sight glasses in ductile steel and meet 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). - with stop valves and sight adapter in acrylic glass ready for insulation on site (LLG SF). The range is based on 3 basic sight glasses: LLG 185, LLG 335 and LLG 740. The other standard lengths are combined by using variations of basic glass lengths. LLG sight glasses 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 frames are mounted together from the front with countersunk allen screws. This ensures easy insulation on site as well as easy inspection and service, if required. The sight glasses are equipped as standard with a built-in safety system (non return device).
