Hydraulic separator Termojet flanged in thermal insulation with base HS-34F

Hydraulic separator HS-34F is a flanged low-loss header (hydraulic separator, thermo-hydraulic distributor) of the Termojet Mega series, supplied in thermal insulation and with a base for floor mounting. A body of 425 mm diameter and a maximum flow of Gmax 95.1 m³/h cover a boiler room of up to 1100 kW at ΔT=10 °C and up to 2200 kW at ΔT=20 °C. All four branches are flanged DN 150 (GOST 12820-80, PN16), so the unit connects straight to the pipework without adapters.

How it works: the hydraulic separator creates a zone of low pressure loss between the primary circuit (boiler or cascade) and the secondary consumer circuits. When the flow rates differ, the surplus or shortfall of water passes through the separator body — boiler pumps and consumer pumps stop competing for flow, and the boiler settles into its design regime. At the same time the unit cleans the system: dissolved gases and microbubbles rise to the top and leave through the air vent, while sludge settles in the lower part of the body and is drained through the drain valve. The insulation removes heat losses in the boiler room and prevents condensation on the body.

Applications: industrial and commercial boiler rooms, boiler cascades, heat substations, systems with many pump circuits. The flanged version is chosen where the pipework is already built on flanges and a demountable joint is needed for servicing without cutting pipes. If the site uses Grinnell grooved couplings, the same body is available as HS-34 of the Termojet Mega series. Neighbouring sizes — HS-33F.

Advantages of the HS-34F hydraulic separator:

• DN 150 flanges directly on the body — no flange adapter kit needed, the joint is demountable from the start;
• hydraulic separation, air venting and sludge settling in a single body;
• insulation and base included — the unit stands on the boiler room floor without supports and without extra lagging;
• steel body of our own production in Ukraine, manufacturer’s warranty.

Technical data: maximum flow Gmax 95.1 m³/h, output 1100 kW at ΔT=10 °C and 2200 kW at ΔT=20 °C, flanged DN 150 connection (flange outside diameter 280 mm), body diameter 425 mm, centre-to-centre distance of the branches 900 mm, height with base 1660 mm, width across the flanges 825 mm, depth 507 mm.

What it is installed with. To connect the separator to a distribution manifold, use the KCH150/150 kit from the Termojet Mega series — the distribution manifolds themselves are there too, for the required number of circuits. Each circuit downstream of the manifold is easiest to assemble from ready-made Termojet pump groups. If the system water is dirty or the circuit carries a lot of air, add air and dirt separators alongside: the low-loss header removes the bulk of gas and sludge, and the separator polishes the water. For heat pump installations see Termojet heat pumps. Smaller threaded sizes are in the Termojet hydraulic separators catalogue.

Frequently asked questions

How does HS-34F differ from HS-34 of the Mega series?
The body, insulation and hydraulics are identical: the same 95.1 m³/h flow, the same 425 mm diameter and 900 mm centre distance. The only difference is the branches: HS-34F has DN 150 flanges, HS-34 has Grinnell grooved ends.

What size of boiler room does HS-34F cover?
Up to 1100 kW at the standard ΔT=10 °C and up to 2200 kW at ΔT=20 °C — the level of a cascade boiler room or a commercial heat substation. The limit is set by the maximum flow of 95.1 m³/h.
