Description

The Spirax Sarco SC20 sample cooler is used to cool samples

of boiler water or steam. The cooler consists of a stainless steel

coil, through which the sample flows, and a stainless steel body,

through which cooling water flows in the opposite direction.

A pre-drilled mounting bracket is incorporated into both end caps.

The SC20 is also available with a clamp adaptor for connecting to

an industry standard 1⁄2" sanitary clamp fitting.

Principal features:

- For boiler water, steam, or condensate sampling.

- Stainless steel body and coil to minimise corrosion.

- Counter current flow for efficient cooling.

Available types:

BSP connections (6 mm O/D tube).

NPT connections (6 mm O/D tube). A 1⁄4" NPT male x 6 mm O/D

stud coupling is supplied loose for connecting the sample inlet

tube to an NPT inlet valve or fitting.

BSP sample cooler kit (SCS20), complete with sample inlet valve,

cooling water inlet valve, and carbon steel fittings.

A kit (SCS20), as above, but with stainless steel fittings.

A sample cooler (BSP or NPT) with a clamp adaptor suitable for

connection to an industry standard 1⁄2" sanitary clamp fitting (clamp

not supplied).

Special sanitary sample coolers (SSC20) are also available in BSP

and NPT. They have a stated coil internal finish. See separate

literature for further details.

Note: The SC20 sample cooler is not polished or specially treated

internally, and the internal finish of the coil is not specified.

Stainless steel couplings are also available separately:-

1⁄4" BSP male x 6 mm O/D tube.

1⁄4" NPT male x 6 mm O/D tube.
