Aquarius® Heating Systems for Purified, DI Water & UPW

Heateflex Aquarius Deionized (DI) Water Heater Systems

Overview

Aquarius® water heating systems are ideal for high-purity processes that require accurate, precise temperature control and continuous flows of hot purified water, such as deionized (DI) water or ultrapure water (UPW). They feature Heateflex® heating coils, Power-to-Flow™ control systems, and operator safeties. Various output options help meet demanding flow and temperature requirements. Aquarius® provides an operational cost savings by reducing the need for multiple heaters. Aquarius-ECO™ models are also available for improved water and energy conservation.

Power-to-Flow™ Control

Power-to-Flow™ controls provide accurate temperature output in single-pass heating applications. It eliminates undesirable overshoots or drops in temperature. The sophisticated control systems feature multi-loop capability and feed-forward functions to moderate variations in the process flow rate. It measures flow and temperature at various stages, and adjusts the power applied to each heating zone accordingly. This advanced integrated system reacts quickly to flow variations to provide a steady stream of DIW at a stable temperature.

Aquarius-ECO™ systems are upgraded recirculating models that utilizes ultrapure White Knight pumps with Heateflex’s advanced heating technology. This upgraded system improves performance and provides energy and water savings while still providing the same temperature performance. The valve may be located at the point of use.

Demand Mode: Fluid goes to process when it is in demand.

Recirculation Mode: Fluid recirculates and maintains temperature. No fluid is used.
