Induction Mode – Bringing Cool Fresh Outdoor Air Directly to the Occupied Zone
The SunCooler™ has four autonomous operating modes. One of its most powerful is Induction Mode. In this mode the SunCooler opens its internal dampers and pushes large volumes of outside air downward in a high-velocity turbulent column that strikes the floor and mixes throughout the occupied zone.
Unlike Exhaust Mode (which pulls hot air from the ceiling and draws replacement air through any available openings that may not be at floor level), Induction Mode creates positive pressure and delivers cool fresh outdoor air directly to the occupants and lower racks. The air column reaches the floor, providing powerful psychrometric cooling and air velocity exactly where it is needed most.
Built-in temperature and humidity sensors work with SunConfig programming to automatically choose Induction when outdoor conditions are beneficial, or switch to Exhaust if needed preventing counterproductive warm or humid air from being introduced.
- Direct floor-level delivery: High-velocity column reaches the occupied zone and penetrates racks and aisles below the unit
- Powerful psychrometric cooling and air velocity right at occupant level for superior heat-stress relief
- Smart sensor control: SunConfig and temperature/humidity sensors automatically select Induction or Exhaust based on facility needs
- Works completely off-grid: Solar + battery powered, day or night

The Dramatic Benefits of Induction Mode
Induction Mode stands out when you need fresh outdoor air delivered directly to the people and product on the floor. The high-velocity column strikes the ground, mixes upward, and provides real psychrometric cooling and air velocity exactly where it matters most.
- ✅ Direct psychrometric cooling at occupant level: Cool fresh air reaches the floor and flows across people for superior heat-stress relief
- ✅ Excellent rack & aisle penetration below the unit. Unlike Exhaust Mode, induction air reaches the lowest levels and dense storage areas
- ✅ Positive-pressure fresh-air delivery that drives outdoor air across occupants instead of potentially bypassing them
- ✅ Intelligent sensor control: Temperature and humidity sensors + SunConfig automatically choose Induction or switch to Exhaust to avoid counterproductive conditions
- ✅ Regulates facility temperature and humidity by injecting cooler, drier outdoor air when beneficial
- ✅ Reduces HVAC runtime and energy costs while improving comfort and productivity
- ✅ Same unit also delivers Exhaust, Nightflush, and Destratification: One solar ventilator for all four modes
Perfect For:
Induction Mode pushes cool outdoor air directly to the floor for maximum occupant comfort and cooling.

Frequently Asked Questions – Induction Mode
1. What is the main difference between Induction Mode and Exhaust Mode?
Induction Mode pushes cool fresh outdoor air downward in a high-velocity column that strikes the floor and mixes at occupant level, creating positive pressure. Exhaust Mode pulls hot air out through the ceiling and draws replacement air through any openings (which may not be at floor level). Induction delivers air directly to people and lower racks; Exhaust removes contaminants from above.
2. Why would I choose Induction Mode over Exhaust Mode?
Induction is often the better choice when occupant comfort and heat-stress relief are the priority. The fresh-air column reaches the floor and flows across people, providing powerful psychrometric cooling and air velocity exactly where it is needed. Exhaust is excellent for contaminant removal, but Induction is superior for direct cooling of occupants and lower storage areas.
3. How does Induction Mode provide psychrometric cooling?
By delivering high-velocity fresh outdoor air directly to the occupied zone, Induction accelerates convective and evaporative cooling on the skin. This proven effect significantly increases heat tolerance even in facilities without air conditioning. It is especially effective for heat-related stress in manufacturing, warehouses, and correctional facilities.
4. Does the SunCooler automatically decide when to use Induction vs Exhaust?
Yes. Built-in temperature and humidity sensors work with SunConfig programming to intelligently choose Induction when outdoor air is beneficial, or switch to Exhaust when it would be counterproductive. You set the logic once and the system runs autonomously.
5. Can Induction Mode bring in too much humidity?
The SunCooler prevents this. The sensors and SunConfig allow you to set humidity limits so the unit will only induce when outdoor conditions are favorable, or automatically switch to Exhaust or Destratification if humidity would rise undesirably.
6. How well does Induction Mode penetrate racks and aisles?
Extremely well. The high-velocity downward column reaches the floor and flows into dense rack aisles and lower storage levels, areas that Exhaust Mode (which pulls from the ceiling) often cannot reach effectively.
7. Is Induction Mode useful year-round?
Yes. In summer and shoulder seasons it brings in cool outdoor air for free cooling and ventilation. In cooler months it can still be used selectively when outdoor conditions are favorable, while the same unit switches to Destratification for heating savings or Nightflush for pre-cooling.
8. How is Induction Mode scheduled or triggered?
Through the intuitive SunConfig GUI you can set daily schedules with any fan speed and duration, or let temperature, humidity, or CO₂ sensors trigger Induction automatically for truly hands-off operation.
9. Does Induction Mode work alongside existing HVAC systems?
Perfectly. It reduces the load on mechanical cooling by introducing cool outdoor air directly to the occupied zone, often shortening HVAC runtime and lowering energy costs while improving overall comfort.
10. Can Induction Mode be combined with the other SunCooler modes?
Yes. The SunCooler is a true 4-mode system. You can schedule or sensor-trigger any combination. For example, many facilities run Induction during the day for fresh-air cooling and switch to Nightflush at night for pre-cooling or Destratification in winter for heating savings.
