View system integration details
This page explains how Heating Jacket is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A thermal management component that uniformly heats the walls of a VPI chamber to maintain precise temperature control during the impregnation process.
Technical details and manufacturing context for Heating Jacket
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Heating Capacity | 5–20 kW | Depends on chamber volume and required heat-up rate |
| Operating Temperature | 50–150 °C | Max continuous temperature for standard insulation |
| Temperature Uniformity | ±2 °C | Across the heated surface at steady state |
| Heating Element Voltage | 220–480 V AC | Three-phase or single-phase as specified |
| Power Density | 1–3 W/cm² | Higher density reduces element life |
| Insulation Resistance | ≥100 MΩ | At 500 V DC test voltageIEC 60364-6 |
| Dielectric Strength | 1500 V AC | For 1 minute without breakdownIEC 60364-6 |
| Sheath Material | SS304/316 | Corrosion resistance for chemical exposureASTM A240 |
| Max Sheath Temperature | 200 °C | Above this, insulation degrades |
| Ingress Protection | IP54–IP65 | Dust and water spray protectionIEC 60529 |
| Weight | 50–200 kg | Depends on size and insulation thickness |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | Designed for atmospheric to 1.5 bar absolute pressure in VPI chamber |
| other spec: | Heating uniformity: ±5°C across chamber walls; Power density: 2-5 W/in² depending on insulation; Response time: <30 minutes to reach setpoint from ambient |
| temperature: | Typically -20°C to +200°C operational range, with precise control within ±2°C of setpoint |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The heating capacity typically ranges from 5 to 20 kW, depending on the chamber volume and required heat-up rate. Confirm the exact value for your specific model with the manufacturer.
The standard operating temperature range is 50 to 150 °C, with a temperature uniformity of ±2 °C across the heated surface at steady state. Verify the maximum temperature for your application.
The jacket typically uses a stainless steel casing (SS304/316), mineral insulated heating cables or resistance wire, ceramic insulators, and high-temperature thermal insulation such as ceramic fiber blanket.
The insulation resistance and dielectric strength are referenced to IEC 60364-6, with minimum values of 100 MΩ at 500 V DC and 1500 V AC for 1 minute, respectively. Always verify compliance with the manufacturer.
