# Industrial Specification: Temperature Control Unit

## 1. Technical Definition
A precision thermal management component that regulates and maintains specific temperature conditions within a continuous flow pharmaceutical reactor system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **2-95°C with ±0.1°C stability at 10 L/min flow rate**. Failure boundary: **Thermal runaway initiates at 105°C coolant temperature or 0.5°C/min uncontrolled heating rate**, Mechanism: **Peltier element thermoelectric degradation beyond 100,000 thermal cycles at ΔT&gt;50°C, causing Seebeck coefficient reduction from 400 μV/K to &lt;200 μV/K**.

### 2.1 Analytical Physics Model
Governed by the **LMTD Logarithmic Mean Temperature Difference**:

> **Primary Equation**: $Q = U \cdot A \cdot \Delta T_{lm}$  
> **Engineering Impact**: Sizing validation for pasteurization and cooling tunnels.
