Core Manufacturing
Plate exchangers are assembled from thin aluminium or polymer foils that are brazed, bonded, or welded into counterflow or cross-flow cores. Rotary wheels are built from corrugated aluminium or molecular-sieve coated media wound onto a hub and balanced to run true at speed.
Process Control
- Incoming foil and media inspected to thickness and coating tolerances
- CNC folding and robotic stacking for repeatable core geometry
- Vacuum brazing or food-grade adhesive bonding for sealed air paths
- Leak testing of each core to confirm exhaust and supply air stay separate
Quality System
Production runs under an ISO 9001 quality management system. Key checkpoints include core pressure test, leakage rate, and dimensional verification against the design drawing. Batches are traceable by serial number back to the shift and materials used.
Why It Matters for You
A core that leaks between airstreams contaminates the supply air and quietly destroys the efficiency you paid for. DocumentedQA and leak testing are the difference between a datasheet number you can trust and one you cannot.
Our Approach
The work described in Manufacturing & Quality Assurance reflects how we approach heat-recovery equipment: start from the real duty, size the core from measured airflow and temperature, and validate performance before delivery. Rather than offering a generic unit, we match plate, rotary, or heat-pipe construction to the exhaust cleanliness, recovery target, and pressure-drop budget of each application.
Capabilities
Our scope covers design, manufacturing, and testing of air-to-air heat exchangers for HVAC, drying, and process ventilation. We support make-up air units, paint and coating ovens, data-center and inverter cooling, and general industrial ventilation where energy cost is a concern. Standard flanged connections and flexible mounting keep integration straightforward for the installer.
Quality and Standards
Production follows documented quality procedures, with material and leak checks at key stages and performance verification against the stated ratings. Certifications and test records are available so the supplied unit can be audited against the specification. This discipline is what lets a recovery project deliver its predicted saving over the equipment's service life.
Frequently Asked Questions
Can you size from our site data? Yes; send measured airflow and temperatures and we return a core sized for the duty. Do you support retrofits? Most units are built to drop into existing ductwork with minimal change.
Practical Selection Checklist
For the Manufacturing & Quality Assurance duty, confirm the measured airflow and the temperature difference between the two airstreams before specifying any unit. Choose the core type that matches the exhaust cleanliness and the recovery target, allow margin for fouling, and verify the pressure drop stays inside the fan curve. Place filtration ahead of the core and provide a condensate drain where the supply side may fall below the dew point.
When to Specify This Solution
Energy recovery suits any plant or building that expels warm exhaust continuously while drawing in fresh air that must be conditioned from ambient. Common candidates include make-up air units, drying rooms, commercial kitchens, paint booths, and general process ventilation. Where the annual cost of heating or cooling make-up air is material, a correctly sized exchanger usually pays back within one to three operating seasons.
Next Steps
Start by logging the supply and exhaust conditions for a full duty cycle, then size the core from those numbers rather than from nameplate estimates. Compare the projected energy saving with the equipment and installation cost to get a payback figure, and review the comparison and product guides for the specific configuration that fits your site.
