The Test Rig
Efficiency is not guessed - it is measured. A balanced test rig drives two controlled air streams through the exchanger and records temperature and humidity on both the supply and exhaust sides. From those readings we calculate sensible effectiveness, latent (enthalpy) effectiveness, and pressure drop.
Following EN 308
Our testing follows EN 308, the European standard for heat exchanger test methods. Running the rig at several airflow and temperature-difference points produces a curve rather than a single marketing figure, so engineers can see performance at part load, not just at the rated point.
CFD and Prototyping
- Computational fluid dynamics to optimise channel geometry
- 3D-printed andimetre-scale prototypes for rapid iteration
- Condensation and frost-risk modelling for cold-climate duty
Turning Data Into Design
The output of R&D is a selection dataset: effectiveness versus face velocity, pressure drop versus airflow, and frosting limits. That dataset is what lets a sizing tool predict real-world behaviour instead of quoting a best-case number.
Our Approach
The work described in R&D and Performance Testing 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 R&D and Performance Testing 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.
