Product Overview
The Thermal Insulation Pad is an important sealing and insulation component used in full premix condensing heating systems. It protects the stainless steel heat exchanger from excessive heat and mechanical stress while ensuring combustion gases remain properly contained. With effective thermal insulation and stable structural support, it enhances boiler reliability and operational efficiency.
Key Features
3.1 High Temperature Resistance
Designed to withstand continuous temperatures up to 1000°C. Suitable for direct contact with premix burner surfaces. Stable performance — no shrinkage, no cracking, no melting under normal operating conditions.
3.2 Excellent Sealing Performance
Dense fiber structure provides a tight, airtight seal. Prevents combustion gas leakage at high-pressure and high-temperature joints. Maintains sealing integrity over thousands of thermal cycles (heating and cooling).
3.3 Vibration Damping
Absorbs vibration from the fan and burner. Reduces noise transmission to the boiler body. Protects heat exchanger from mechanical fatigue cracking.
3.4 Corrosion & Condensate Resistance
Resistant to weakly acidic condensate (pH 3–5) in condensing boiler environments. Does not absorb moisture or degrade in humid operating conditions. Long-term chemical stability.
3.5 Lightweight & Easy to Assemble
Thin profile design — does not add unnecessary size or weight to the system. Clean cut edges for precise installation. Compressible material ensures a uniform contact surface even on slightly uneven flanges.
3.6 Custom Shapes & Sizes
Can be manufactured to any shape — round, rectangular, irregular profiles. Available with pre-punched holes, cut-outs, or special edge treatments as required. Matches all standard and custom heat exchanger flange dimensions.

5. Our Unique Advantage
We Make Both the Pad AND the Heat Exchanger
This is our most important advantage — and it sets us apart from all ordinary insulation suppliers.
| Benefit | Explanation |
| Perfect Fit — Every Time | Our insulation pads are designed and tested directly on our own heat exchangers. No guesswork. No mismatches. |
| Pre-Validated Assembly | Every pad size and shape has been physically fitted and tested on the heat exchanger before delivery. |
| Proven in Real Conditions | We run combustion tests, thermal cycling tests, and leak tests — with the pad installed — so you receive a validated, matched set. |
| One Supplier, One Responsibility | You don't need to coordinate between a pad supplier and a heat exchanger supplier. We handle everything. |
| Competitive Price | Because we produce both in-house, we eliminate middleman costs. You get better quality at a lower price. |
| Faster Problem Resolution | If any issue arises, we own the full system — we can diagnose and solve it faster than any third-party supplier. |
6. Product Range — What We Can Supply
Option A: Insulation Pad Only
Supply insulation pads to fit your existing heat exchanger design. Provide sample or drawing → we manufacture and deliver.
Option B: Insulation Pad + Heat Exchanger (Matched Set)
Supply a fully matched and pre-tested heat exchanger + insulation pad. Ready to assemble into your boiler system. Reduces your assembly time and quality inspection cost.
Option C: Full OEM / ODM Cooperation
We manufacture under your brand (OEM). We develop new designs based on your specifications (ODM). Non-disclosure agreements available. Tooling support and engineering consultation included.
7. Quality Assurance
Every insulation pad we supply goes through the following checks:
| Test | Purpose |
| Dimensional Check | Confirms exact fit to specified drawing |
| Density & Compression Test | Ensures material consistency and sealing pressure |
| High-Temperature Aging Test | Confirms no degradation after thermal cycling |
| Combustion Leak Test (with HEX) | Validates airtight seal when installed on our heat exchanger |
| Visual & Surface Inspection | Checks for cracks, inclusions, or surface defects |
All products are manufactured under ISO 9001 quality management standards.
