Single Fluid Transfer System Overview

Manufacturing Process such as API, involve batch reaction, separation, filtration, distillation and drying; batch reaction involves heating and cooling stages ranging from -40˚C to 150˚C. Conventionally, this is done with multiple utilities such as chilled brine, chilled water, cooling water, hot water, low pressure steam, high pressure steam etc.

Contrary to the traditional use of multiple utilities, single fluid heat transfer systems are advantageous. These system can be designed for specific applications.

Case Study: Single Fluid Heat Transfer System for Accurate & Efficient Thermal Management in Batch Processes

An industrial solution for precise, flexible, and contamination-free heat transfer across wide temperature ranges

Project Overview

A multi‑product pharmaceutical and specialty chemicals manufacturer sought to improve thermal control across batch reaction and downstream processes. The client’s existing heat transfer utilities relied on multiple service fluids (e.g., chilled water, cooling water, hot water, low- and high-pressure steam), which introduced cross-contamination risks, thermal shocks, utility changeovers, and inconsistent temperature profiles.

To overcome these limitations and enable precise temperature control, consistent product yields, and safer operations, a customized Single Fluid Heat Transfer System (SFHTS) was engineered and installed. This system uses a single heat transfer fluid for both heating and cooling cycles, eliminating the need to switch utilities while delivering accurate, repeatable thermal control throughout the production process.

These challenges negatively impacted product quality, process efficiency, and overall operational safety.

Engineered Solution: Single Fluid Heat Transfer System

The Single Fluid Heat Transfer System (SFHTS) was developed to replace traditional multi-utility systems for heat transfer with a single controlled heat transfer fluid carefully selected based on operational temperature range and thermal stability.

This system integrates:

The system integrates a centralized heat transfer fluid circulation skid with a programmable temperature control unit (TCU).
