Data centers waste enormous heat 24/7. An air-to-air heat exchanger enables free cooling: when outdoor air is cool, it pre-cools the data-hall supply using exhaust, slashing compressor runtime and PUE.
Why plate, not wheel
- No carryover into critical halls, separated streams protect equipment.
- No moving parts in the airstream, reliable for 24/7 duty.
- Indirect evaporative (IEC) pairs well for hotter hours.
Recovering the heat
Exhaust heat can warm adjacent offices, warehouses or make-up air. Even modest recovery on a 500 kW load is worth tens of thousands per year. Avoid rotary wheels here, see plate vs rotary and the efficiency guide.
Specifying a unit for your project?
EN159 builds plate, rotary, heat-pipe and counterflow air-to-air exchangers. Send airflow (m3/h), inlet temperatures and available space and we will size it.
