SGP - Sight Glasses
Danfoss sight glasses with hard crystal view ports are designed to accurately indicate the presence of moisture in refrigeration and airconditioning
systems. When system moisture content rises above permissible levels, the “dry/green” indicator will change to yellow indicating
a “wet” system. The indication of dangerous moisture levels is essential in helping prevent the formation of harmful acids which are detrimental
to the system. The SGP sight glass is simply the best-made sight glass available today.
