TEE DTS heat Exchanger – Hygienic Heat Exchangers for Pharmaceutical Applications
The TEE DTS heat Exchanger is a sanitary shell-and-tube heat exchanger specifically engineered for pharmaceutical water systems, including PW (Purified Water), WFI (Water for Injection), and Pure Steam (PS). Designed to meet the strictest industry standards, it ensures safe and efficient heating, cooling, sterilization, and sanitization processes in pharma environments.
Pharmaceutical Applications
Heating/Cooling of WFI, PW, and PS Sterilization loops for tanks and distribution systems Utility/product separation in critical process steps
Risk-Free Operation – Double Tube Sheet Design
Our Double Tube Sheet (DTS) configuration prevents cross-contamination between product and utility fluids. In the event of internal leakage, any fluid loss is externally visible, allowing immediate detection and ensuring product integrity.
