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 ½" 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).
