As a manufacturer with over 25 years of experience in metal fabrication, Anping County Boli Hardware Wiremesh Products Factory is proud to introduce our Custom Heat Recovery Exchanger – High-efficiency Pillow-type, specifically engineered for HVAC systems and industrial cooling applications. Our factory, established in 1998, has exported over US$5 million annually to global markets, serving clients from North America to Southeast Asia. This pillow-type heat exchanger is designed to maximize thermal recovery while minimizing pressure drop, offering a compact and robust solution for waste heat reuse. With our in-house customization capabilities, every unit can be tailored to fit your exact ductwork, piping, and performance requirements.
The pillow-type design uses a unique corrugated plate geometry that creates turbulent flow, significantly enhancing heat transfer coefficients compared to traditional shell-and-tube or flat-plate exchangers. This results in up to 30% higher efficiency in recovering heat from exhaust air or process streams, reducing energy costs and carbon footprint. Whether you need to preheat incoming fresh air in an HVAC system or capture waste heat from industrial cooling towers, our exchanger delivers consistent performance under demanding conditions.
Key Features & Technical Specifications
- Pillow-type plate geometry – Induces high turbulence for superior heat transfer.
- Compact footprint – Up to 60% smaller than conventional heat exchangers for the same duty.
- Wide material selection – Stainless steel (304/316L), copper, or carbon steel, with optional anti-corrosion coatings.
- High working pressure capacity – Standard up to 2.0 MPa; higher on request.
- Temperature range – From -20°C to +250°C, suitable for both HVAC and industrial processes.
- Customizable connections – Flanged, threaded, or welded ends per your design.
- Easy maintenance – Modular design allows quick access for cleaning or inspection.
- Low pressure drop – Optimized flow passages reduce fan/pump energy consumption.

Frequently Asked Questions (FAQ)
-
What is the typical lead time for a custom heat exchanger?
Standard designs take 15–20 working days; custom units with non-standard dimensions or materials require 25–35 working days, depending on complexity. -
Can I use the exchanger for both heating and cooling recovery?
Yes, the pillow-type design is reversible and suitable for both heat recovery from exhaust air and cooling recovery from chilled water loops. -
What materials are available for corrosive environments?
We offer stainless steel 316L, titanium, and Hastelloy coatings for aggressive media. Please provide the fluid composition for a recommendation. -
How do I maintain the pillow-type heat exchanger?
Regular cleaning with compressed air or mild chemical flush is recommended. The modular design allows easy disassembly for manual cleaning. -
Do you provide thermal performance data for my specific conditions?
Absolutely. We can perform thermal calculations based on your flow rates, inlet/outlet temperatures, and fluid properties, providing a detailed performance sheet. -
What certifications do your products meet?
Our products are manufactured according to international standards (e.g., ASME, PED, GB). We can provide material certificates and pressure test reports upon request. -
Can I request a sample or small quantity for testing?
Yes, we can produce a prototype unit (minimum area 0.5 m²) for evaluation. Contact our sales team for pricing and lead time. -
What is the warranty period?
We offer a standard 12-month warranty against manufacturing defects, extendable up to 24 months for an additional cost.
