UP Series, Ultrapure Deionized Water Heaters

The Lufran^® UP Series Ultrapure DI Water Heater has been designed to deliver years of trouble-free, low maintenance operation. To date, over 1100 UP Series water heaters have been sold worldwide. The UP Series accommodates any temperature setting up to 100°C +/- 1°C and any flow rate.

The Lufran^® UP Series point-of-use, in-line system quickly heats DI water with the minimum amount of exposed surface area. An ultra-clean environment is provided with no metal-to-water contact. Wetted surfaces are of fluoropolymer (heater) and PVDF (liner). The UP Series incorporates Patented, all PTFE fluoropolymer high wattage heaters with a nitrogen purge feature. Included with the heater is a Process Control Module(s) which incorporates a digital PID controller and multiple safety features.

OUTSTANDING FEATURES INCLUDE:

• Patented heater purge ensures heater integrity, longevity and temperature stability. 
• Heaters are in direct contact with the DI water for fast response.
• Constant flow feature ensures that water is not allowed to stagnate, thereby preventing the buildup of contaminants. (DI water bleed available to inhibit bacterial/ fungal growth.)
• Compact modular design allows systems to be used independently or in combinations. Models from 7 to 260 Kilowatts.
• All instrumentation is isolated from the DI water.
• Accommodates any flow rate, temperatures up to 100°C and pressures up to 100 PSIG.

SAFETY FEATURES/ANNUNCIATORS

Every Lufran^® UP Series DI Water Heater is protected against accidental damage. The operator's safety is assured through a network of interlocking safety devices.

• Heater Purge Exhaust Monitor: The purge monitor analyzes the humidity level of the purge exhaust gas as it flows through the heating elements, ensuring heater integrity.
• Capacitance Liquid Level Sensor: Sensor mounted externally to the exit plumbing, ensures that a safe water level is maintained during heater operation.
• Internal Heater Monitor: A factory set over-temperature control device (OTCD) continuously monitors a sensor that is built into the heating element, ensuring that the heating element is operating within a safe temperature range.
• High Process Temperature Limiting Control: A factory set independent high process temperature limiting control monitors the heated DI water exiting the system to prevent excessive outlet temperature. This control uses an independent thermocouple and power relay to provide complete redundancy to the primary temperature control network.
• System Pressure Monitor: A factory set low pressure limiting control monitors the pressure of the incoming DI water supply to prevent heater operation during a low pressure condition that may result in the generation of steam.
• Temperature Control High Alarm: The process temperature controller's high alarm prevents heater operation above a preset maximum temperature.
• Optional UPDI-DAC control option available.
• Optional solid state relay upgrade available.
