Product overview

What it does, and where it fits.

The glass shell and tube heat exchanger is a recent development in the range. It can be used for condensation of vapours, vapourisation, and cooling and heating of liquid, and it is available in various combinations of glass, metal and FRP in the shell or the tube. Process fluid passes through a bundle of tubes while the service fluid circulates in the shell around them, with baffles directing the shell-side flow across the bundle instead of straight along it.

The range covers twelve models on three shell sizes. A 150 DN (6") shell carries 37 tubes and gives 3 to 6 m²; a 225 DN (9") shell carries 73 tubes for 6 to 12 m²; a 300 DN (12") shell carries 151 tubes for 12 to 25 m². Within each shell, area is increased by lengthening the exchanger rather than widening it — which is why L runs from 2500 mm at the smallest model to 4550 mm at the largest.

The catalogue reference reads directly as shell size over area: RGG/RMG 9/12 is a 9-inch shell with 12 m² of heat transfer area. Tube diameter is 14 mm throughout, and the baffle count rises with length so shell-side velocity is maintained as the exchanger gets longer.

Features

Built into every unit.

Twelve models from 3 m² to 25 m² of heat transfer area
Three shell sizes — 150 DN, 225 DN and 300 DN
37, 73 or 151 tubes depending on shell size
14 mm tube diameter throughout the range
Baffle count from 5 to 23, rising with exchanger length
Nozzles can be changed as per the client's requirement
Four nozzle connections — DN1 through DN4 — on every model

Benefits

Why it earns its place in the line.

Large transfer area in a compact shell — 25 m² inside a 300 DN body
Baffled shell side drives cross-flow over the bundle for a better transfer coefficient
Area is increased by length, so the plot footprint barely changes across a shell size
Nozzle sizes and positions adapted to the client's pipework rather than fixed
Overlapping ranges — 6 m² and 12 m² are each available on two shell sizes, so the choice can be made on pressure drop rather than area alone

All dimensions in mm, transcribed from the catalogue page and transposed to one row per model. The catalogue prints this table with one column per model; it is transposed here to one row per model, with no value altered. Two notes are printed on the page and apply to every model: tube diameter is 14 mm, and nozzles can be changed as per client's requirement. DN, DN1 to DN4, H1, H2, C, C1, C2, T, E, the tube count and the shell size are constant within each shell group; L, L1, L2, L3 and the baffle count vary by model.

FAQ

Questions we are asked about this item.

Shell size in inches over heat transfer area in m². RGG/RMG 9/12 is a 9-inch (225 DN) shell with 12 m² of area. 12/25 is a 12-inch (300 DN) shell with 25 m².

14 mm across the whole range — the catalogue states it as a note on the table rather than as a per-model column.

Yes. The catalogue states directly that nozzles can be changed as per client's requirement. The DN1 to DN4 figures in the table are the standard arrangement.

Because they are available on two different shells. 6 m² comes as 6/6 on a 150 DN shell or 9/6 on a 225 DN shell; 12 m² comes as 9/12 or 12/12. Same area, different shell diameter, different shell-side velocity and pressure drop — pick on the hydraulics, not the area.

By length. The tube count is fixed by the shell — 37, 73 or 151 — so more area means a longer exchanger. L runs from 2500 mm to 4300 mm inside the 150 DN shell alone, and the baffle count rises with it to keep shell-side velocity up.
