Applications
It is a high quality DTS shell & tube heat exchanger especially meets the high hygienic demands of the pharmaceutical industry. The heat exchanger was designed to work in the highest hygienic conditions in applications such as water-for-injection (WFI), Purified Water (PW), and heating/cooling of pharmaceutical products.

Working principle
The product media flows through a bundle of seamless, polished tubes. The service media flows outside the tubes in a cross flow. At the end, the tubes are fastened by two tube-sheets acting as leakage indicators, preventing cross contamination between the product and the service media.
The heat exchanger can be installed horizontally or vertically depending on the duty or space. Thermal fatigue caused by large temperature changes is managed by expansion connection in straight units.

Features and Benefits
• 100% of import Seamless tubes.
• Double tube-sheets to protect against service media leaking  into the product.
• Completely drainable on product side and easy to clean.
• No dead point in the tubes.
• No risk of cross contamination.
• Designed according to FDA and cGMP requirements.
• Flexibility or standard in design.
• A high quality documentation package as standard.

Applications

Ritai sanitary Tube-in-Tube heat exchanger was special developed for WFI point of use cooling application when flow rate is less than 1500Lph, it’s easy to be installed and quickly cooling response time, no contamination risk and free maintenance.
We have two size of Tube-in-Tube heat exchanger, standard operating scope: TIT HEP 01, flow rate 0~1000lph, 85℃ cooling to 40℃ ~ 7 ℃ chilled water; TIT HEP 02, flow rate 1000~1500lph, 85℃ cooling to 40℃ ~ 7 ℃ chilled water.

The three tubes are then bent together 180° to a U-bend. E-Pharma bends the three tubes with the spirals in one step which makes it no leakage risk (no welds in the turn). The product is going in the middle tube and the cooling or heating media in the inner and outer ones.

A counter-current flow gives the most efficient heat transfer and also the possibility to have crossing temperature programs.
Any thermal expansion is taken up by the bend so the unit is very resistant against thermal fatigue that comes from big temperature differences in heating/cooling duties or when sterilizing with steam.
The heat exchanger can be sold as a naked unit or a complete point of use cooler, the module is to prefer since it is easy to install and use directly. The module consists of the E-Pharma Tube-in-Tube, cladding, valve arrangements and a pitot tube arrangement etc.
The pitot tube is especially made for E-Pharma heat exchanger connect to main pipe system.
