Product Cooler
LSHEC series, 0.10 m² to 1.25 m²
Coil battery cooler for distillate and product liquids — product runs through the coil and coolant through the shell, giving longer residence time, with 25 DN distillate connections.
| Product type | Product cooler (coil battery) |
|---|---|
| Flow arrangement | Product through the coil battery, coolant through the shell |
| Distillate connection | 25 DN on every model, for direct connection to distillate lines |
| Shell size range | DN 50 to DN 150 |
| Actual H.T.A. | 0.10 m² to 1.25 m² |
| Length | 450 mm to 850 mm |
| Catalogue reference | LSHEC series |
Product overview
What it does, and where it fits.
The product cooler is used for cooling of liquids, typically for the cooling of distillate from the distillation column. It is the unit that takes hot product leaving a condenser and brings it down to a temperature at which it can be collected or stored.
Unlike a coil condenser, in a product cooler the product travels through the coil battery and the coolant through the shell — the reverse of the usual arrangement. This provides more residence time to the product to be cooled, which is the whole point: a thin stream held longer against a cool surface leaves at a lower temperature than a fast one.
For direct connection with distillate lines, all the product coolers are provided with a 25 DN connection. The range covers seven references from a 50 DN shell up to 150 DN.
Features
Built into every unit.
- Cools liquids, typically distillate from a distillation column
- Product through the coil battery, coolant through the shell
- More residence time for the product than a coil condenser gives
- All models provided with 25 DN connection for direct distillate line connection
- Shell sizes DN 50 to DN 150
- Seven catalogue references
Benefits
Why it earns its place in the line.
- Reversed flow arrangement gives longer contact time and a colder outlet
- Standard 25 DN connection bolts straight to distillate lines
- Glass construction keeps the product visible while it cools
- Coil battery packs substantial area into a small shell

All dimensions in mm, transcribed from the catalogue page and transposed to one row per model. ⚠️ The H.T.A. figure for LSHEC 6/10 reads as 2.70 on the supplied page, which is inconsistent both with the reference pattern (where the figure after the slash is ten times the area, giving 1.00) and with LSHEC 6/15, which is a longer unit at 1.25 m². Confirm this one figure with us before sizing against it. Every other row follows the pattern exactly.
FAQ
Questions we are asked about this item.
The flow is reversed. In a coil condenser the coolant runs in the coil; in a product cooler the product runs through the coil battery and the coolant runs through the shell. That gives the product more residence time and a colder outlet.
25 DN on every model in the range, so it connects directly to distillate lines without an adaptor.
LSHEC 6/10 prints as 2.70 m², but the reference numbering implies 1.00 m² and the longer LSHEC 6/15 is listed at 1.25 m². A shorter unit cannot have more than twice the area of a longer one in the same shell, so we have flagged it rather than publish it as fact. Ask us and we will confirm against the master drawing.
Size on the heat load and the outlet temperature you want. Send us the distillate rate, its inlet temperature and your coolant, and we will confirm the reference.
