Hydraulic separator Termojet in thermal insulation HS-219 flanged with base HS-30

Hydraulic separator GS-30 with thermal insulation — Termojet's flanged hydraulic separator with 2½″ connection and a floor-standing base. This model is designed for high-capacity boiler rooms: up to 250 kW at ΔT=10 °C and up to 370 kW at ΔT=20 °C at a maximum flow rate of 21.5 m³/h.

How a hydraulic separator works: a low-pressure-drop zone is created between the boiler circuit (primary) and the consumer circuits (secondary). When the circuit flow rates differ, excess heat-transfer fluid circulates through the separator body — the pumps do not fight each other, and the boiler or cascade operates in a stable regime, reaching maximum capacity. In addition, the unit purifies the system: the built-in air separator vents dissolved gases to the air vent (½″ BSP male connection), and the built-in sludge trap settles dirt, which is drained through a ½″ BSP male valve. A ½″ BSP male temperature sensor port is provided for automation systems.

Applications: boiler cascades, commercial and industrial boiler rooms, systems with multiple pump circuits and individual heat consumers. For large-area facilities with a heat pump, the GS-30 guarantees stable flow through the heat exchanger — see Termojet heat pumps. If a threaded connection is sufficient for the system, consider the hydraulic separator GS-28 2″ or the GS-27 1½″.

Advantages of the Termojet hydraulic separator:

• 2½″ flanged connection — a reliable demountable joint for large diameters and high capacities;
• floor-standing base for stable installation — no load on the boiler-room wall;
• hydraulic separation, air separation, and sludge settling in one body;
• steel body, manufactured in Ukraine, manufacturer's warranty.

Technical specifications: maximum flow rate Gmax 21.5 m³/h, capacity 250 kW at ΔT=10 °C and 370 kW at ΔT=20 °C, flanged 2½″ connection, centre-to-centre pipe spacing 450 mm, height 925 mm, width 490 mm, volume 35.78 l.

Smaller sizes with threaded connections are available in the Termojet hydraulic separators catalogue.

Frequently Asked Questions

Why is a flanged connection chosen for large boiler rooms?
Flanges provide a reliable demountable joint for large diameters: the unit can be easily dismantled for maintenance, and the connection operates confidently at high heat-transfer fluid flow rates.

What capacity does the GS-30 handle?
250 kW at ΔT=10 °C and 370 kW at ΔT=20 °C at a maximum flow rate of 21.5 m³/h — this is the level of a cascade boiler room or commercial facility.
