Aquarius® Deionized (DI) Water Heater Systems

Heateflex Aquarius Deionized (DI) Water Heater Systems

Overview

Aquarius® deionized (DI) water heater is the perfect solution for high-purity heating applications requiring accurate temperature control. Aquarius® heaters provide continuous flows of at-temperature, hot DI water. Its Power-to-Flow Control™ system provides accurate temperature control. The systems eliminate undesirable overshoots or drops in fluid temperature. Aquarius® heaters are available in various models with a range of heater outputs that can provides operational cost savings, and eliminate the need for multiple heaters.

Temperature Control

Aquarius’ Programmable Logic Controller (PLC) uses Power-to-Flow Control to manage multi-loop capability and feed-forward functions. It quickly detects variations in process flow rate and adjusts the power supplied at each zone of the multi-stage heat process, producing a steady stream of DI water at a stable temperature.

Safety Built-In

Aquarius® includes a wide range of operator safety features. For example, the system includes an advanced ground fault circuit interrupter (GFCI) system with a sub-30 mamp rating. Furthermore, it has a Short Circuit Current Rating (SCCR) of 100,000 Amps. And, the door interlocks, the EMO, and the GFCIs feature redundant safety PLC systems, and NIST-certified thermocouples. Finally, dual pressure relief valves ensure rapid dissipation for both input and output flows.

Highlights

At the heart of the Aquarius® is the patented Heateflex heating coil, with PVDF/PFA wetted surfaces. DI water temperature is 95º C (203º F), with 0.1º C temperature accuracy, at 60 PSIG. Heater flows are 0.5 GPM (1.9 LPM) to 32 GMP (122 LPM). And with models from 40 kW to 225 kW available (200 VAC to 480 VAC, 3-ph), the Aquarius® provides an operational cost savings by reducing the need for multiple heaters.

Power-To-Flow™ Control

Heateflex’s patented Power-To-Flow Control™ is an innovative control system designed to provide accurate temperature output in single pass heating applications. Power-To-Flow Control eliminates undesirable overshoots or drops in temperature. The sophisticated Aquarius® temperature control system features multi-loop capability and feed-forward functions to compensate for variations in the process flow rate. It measures the flow rate of fluid as it comes into the heater, measuring the temperature at various stages in the heating process, and then adjusting the proportion of power applied to each heating zone based on these measurements. This advanced integrated control method reacts quickly to any variations in flow, providing a steady flow of DI water at a stable temperature.

  • Excellent Temperature Stability
  • Rapid Response to Temperature & Flow Variations
  • Eliminates Excessive Overshoots & Drops in Temperature
