GESTRA sample coolers are specially designed for taking samples of boiler water for analysis. They prevent steam flashing off from the sample which is both dangerous and results in an incorrect boiler water analysis.
Sampling is of special importance for the operation of steam boilers. However, proper and uncorrupted analysis values require the right sampling procedure and testing instruments that function correctly. Direct sampling of hot boiler water from pressurized lines always involves the danger of scalding and inevitably leads to false values for the analysis result. Flashing losses within the sampling line or in the sample container cause an increase in the density of the boiler water sample; the samples therefore do not represent the true TDS content (salinity). Flashing losses within the sampling line or in the sample container cause an increase in the density of the boiler water sample; corruption of the analysis result is thus unavoidable. The perfect solution is to use the GESTRA sample cooler PK. The boiler water sample is cooled down to the reference temperature of 25 °C and thus fulfils the basic requirements for precise water analysis. Pre-assembled on mounting panel, with pressure reduction and temperature meter, cooling coil can be removed, body and cooling coil made of stainless steel 1.4541/1.471.
