概述
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.
