Spirax Sarco SafeBloc™ er en dobbeltisoleringsløsning med et unikt pladsbesparende design, der giver kortere installationstid og færre lækager.
Spirax Safebloc er hurtigere og nemmere at installere end en traditionel double block & bleed, har et innovativt design, som inkorporerer to bælgforseglede isolationsventiler og en udluftningsport i én kompakt enhed.
Spirax Safebloc™ er let at bruge og idriftsætte, og den kan installeres uden ændringer i rørsystemet i det rum, der efterlades af en eksisterende enkelt isolationsventil.
