High-Purity DI Water Heaters

Process Technology makes two inline heaters for hot DI and RO water. Both heat the water as it flows, single pass or recirculating, and both keep metals and particles out of the water by choice of wetted material.

The Tytan has titanium heating elements and titanium wetted parts, from 12 kW to 144 kW, wall mounted up to 72 kW. It suits DI and RO rinse water, parts cleaning and medical device lines, where long element life matters more than the last part per trillion.

The Lufran DI has PTFE and PVDF wetted surfaces and a patented purged PTFE-covered element, from 24 kW to 312 kW, for flows of 1 to 200 litres a minute up to 90°C. It’s the choice for ultra-pure water in semiconductor and flat panel fabs.

Questions we’re asked

What should a high-purity water heater be made from?

Anything the water touches has to be a material that won’t shed ions or particles into it. Titanium is used where the water is DI or RO grade and long life is the priority. Fluoropolymers such as PTFE and PVDF are used for ultra-pure water.

How big a heater do I need?

Roughly flow in litres a minute, times the temperature rise in °C, times 0.07. Heating 20 litres a minute from 20°C to 80°C needs about 84 kW.

Can it go on an existing bench or loop?

Yes. Both heaters are made for single pass or recirculating loops. Tell us the pipework, voltage and space you have.
