®
LUFRAN UPDI Features and Benefits
Process Technology introduces the next generation ultrapure water heater
designed for the next generation high purity semiconductor and flat panel
display manufacturing processes. This updated Lufran water heater offers
the ultimate in cleanliness for heating UPDI (ultrapure deionized water).
With thousands of heater installations worldwide, the Lufran boasts proven
technology for UPDI heating applications and is suitable for the most
stringent high purity specifications. It is constructed with all PTFE and
PVDF wetted parts for ultra-low particle count processes. Its patented
“purged” resistive element design offers exceptional MTBF of nearly ten
years and significantly lower maintenance costs than other ultrapure water
heaters on the market.
This heater is Class 100 cleanroom assembled, third party certified to
SEMI and UL standards, and optionally CE compliant. Our standard
patented DAC™ software provides accurate temperature control for
different flow and temperature requirements and sizes up to 312kW are
available.
LUFRAN UPDI Heater Specifications
HEATER: Patented resistive heating system. DAC™
Demand Anticipation Control) for high temperature
accuracy.

OPTIONS:
• Extended Warranty
• Custom Communication Protocol
DAC™ (Demand Anticipation Control)

Extremely precise temperature control and stability: Utilizes a patented temperature/flow algorithm to calculate
exact heater output requirements. Calculates and compares:
• Required percentage power
• Inlet fluid temperature.
• Flow rate.
• Actual power applied.
• Low temperature boost.
• High temperature shut-off.
Quick reacting: Responds instantly to flow changes rather than simply monitoring outlet temperature.
Better temperature stability: Responds quickly to recipe (flow and temperature) changes.
Water conservation: Faster heat up and recovery means less water usage.
Friendly operator interface (User friendly HMI): Touch pad display with easy to understand commands.
