HVAC Tanks

Compression Tanks – ASME

The compression tank on a closed hydronic system serves a very important function in providing adequate pressurization under all operating conditions. Above all, a compression tank must be absolutely air tight. B&G tanks are available nationally in ASME construction, are of black steel construction, thoroughly tested and guaranteed leak proof. Gauge glass tapping are included as standard.

The Compression Tank absorbs the expansion forces of the system water and provides proper pressurization under varying operating conditions. Used with Airtrol Fittings it provides positive air control.
