Shuntopac® 65-100 VÅ

Shuntgroep voor warmteterugwinning

Shuntopac® 65-100 VÅ is een shuntgroep voor warmteterugwinsystemen en is standaard leverbaar met aansluitmaten van DN 65 tot en met DN 100. De shuntgroep kan worden uitgerust met meerdere componenten van elk merk en een aantal verschillende aansluitmogelijkheden .

Shuntopac® 65-100 VÅ wordt geleverd met een brand- en corrosiebestendige afdekking van aluzinkplaat. De isolatie bestaat standaard uit AF / Armaflex AF-4. De shuntgroep is voorzien van een statief met twee poten met voetplaten voor het opzetten en bevestigen aan de vloer.

Het buizenpakket bestaat uit een standaard uitvoering van volledig gelaste drukvatbuizen SS-EN 10216-2, roestwerend gelakt met grijze primer. Leidingpakketten in een andere kwaliteit of met een andere oppervlaktebehandeling kunnen op bestelling geleverd worden.

Shuntopac® 65-100 VÅ is CE-gemarkeerd in overeenstemming met verklaring van de fabrikant 2B volgens de Machinerichtlijn.

De shuntgroep is ecologisch beoordeeld.

System example

Adjustment

Total flow
1. Connect differential pressure instrument to adjustment valve with measuring point.
2. Set the control valve to fully open position (stem depressed, bypass closed).
3. Measure the water until it reaches the calculated value.

Bypass flow
4. Set the control valve to fully closed position (stem up, bypass open).
5. Adjust the inner adjustment valve until the outer adjustment valve achieves the same pressure drop as before.
