Every boiler feedwater and steam condensate analyser on the market — including the Pyxis Guardian IK-2000 series — specifies that it must be installed downstream of a sample cooler. This...
Lecol SWAS
Boiler Sample Conditioning
Representative Samples From Live Steam and Boiler Water
Continuous monitoring of steam and boiler water chemistry depends on getting a safe, representative sample to the analyser — without flashing, cooling losses or contamination along the way. Lecol's Steam and Water Analysis System (SWAS) equipment forms the conditioning train between the process and the analyser: dual-helical-coil sample coolers bring live steam and boiler water down to a safe temperature, rod-in-tube pressure reducers step pressure down without erosion or plugging, cation exchange resin columns and degassed cation conductivity units then measure ionic contamination to ASTM D4519. Autoflo supplies each stage individually or as a complete engineered train.
Non-welded dual helical coil sample coolers — up to 350 bar @ 537°C, extensive heat transfer area, removable body for cleaning
US-patent rod-in-tube pressure reducers — on-line internal flush without interrupting the process or removing equipment
Clear polycarbonate resin columns — 900 mL cation exchange resin with quick-release connectors for fast maintenance
ASTM D4519-compliant degassed cation conductivity units — self-circulating cooling, no-flow alarm, multi-parameter readout
