Hot Water E-Cell Stack MK-3MiniHT

Summary

Product identification

The E-Cell EDI MK-3MiniHT Stack is a hot water sanitizable electrodeionization (EDI) stack designed to provide ultrapure water for the pharmaceutical, biotechnology industries, and laboratories. It uses electrical current and operates continuously, requiring no caustic or acid for resin regeneration, and no brine injection or concentrate recirculation. The stack is leak-free, backed by a standard 3-year prorated warranty. It is designed to minimize cleaning requirements at higher feed water hardness levels through counter-current operation.

Key Specifications:

• Nominal Flow: 1.14 m³/h (5.0 gpm)
• Flow Rate Range: 0.5–1.6 m³/h (2.2–7.0 gpm)
