# Industrial Specification: Heating Jacket

## 1. Technical Definition
A thermal management component that uniformly heats the walls of a VPI chamber to maintain precise temperature control during the impregnation process.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **50-200°C with ±2°C uniformity across jacket surface**. Failure boundary: **Thermal stress exceeding 250 MPa at 250°C differential between heating element and chamber wall**, Mechanism: **Coefficient of thermal expansion mismatch (α_element=17×10⁻⁶/K vs α_wall=11×10⁻⁶/K) causing cyclic fatigue cracking at weld joints**.

### 2.1 Analytical Physics Model
Governed by the **Heat Sterilization F0 Lethality Model**:

> **Primary Equation**: $F_0 = \int_{0}^{t} 10^{(T-121.1)/z} dt$  
> **Engineering Impact**: Validates microbial reduction integrity for aseptic packaging.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| T | Process Temp (°C) | **$T \in [50-200°C]$ °C** (Per `temperature_range`) |
| t | Exposure Time (min) | Engineering Constant |
| z | Z-value | **10 °C** (Standard for *C. botulinum*) |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| PID controller integral windup during rapid temperature setpoint changes | 8 | Overshoot to 230°C causing resin premature curing on chamber walls | Anti-windup compensation with 0.5 second derivative time constant in control algorithm |
| Mineral deposit accumulation (CaCO₃) at 0.5 mm thickness on heating surfaces | 8 | Localized hot spots reaching 280°C due to 65% reduced heat transfer coefficient | Automated citric acid flush system activated at 15% flow reduction detection |

## 3. Key Technical Parameters
