The Lufran fluoropolymer inline water heater is an ultrapure heater designed to heat
DI water with very stringent cleanliness requirements. All wetted surfaces in this unit
are fluoropolymer and PVDF material. There are no metallic wetted surfaces. The
cleanliness of these units has been confirmed by independent third party testing. The
cleanliness report is available upon request.
The Lufran fluoropolymer inline water heaters are available in wattages from 24kW to
288kW. These units consist of one or more heating columns combined with a control
system and all necessary power distribution circuitry in a freestanding enclosure. The
table on page 10 shows the various wattages with the corresponding number of heating
columns. The photo on the cover shows a typical unit with two heating columns.
These units are CE, ETL and Semi S2/S3 compliant.

This system features the patented DAC control system operating from a PLC with a
touch-screen operator interface. The DAC control system provides superior temperature
control and faster response to changes in conditions versus a typical PID temperature
control system.
