Destratification fans

Destratification fans are effective in facilities with a height of over 4 m, and their full potential is revealed at ceiling heights of 6–15 m, where the phenomenon of warm air accumulation under the ceiling is most visible. The higher the facility, the greater the potential savings from destratification.

British research, including studies conducted at the University of Nottingham, has shown that destratification can reduce heating energy consumption by up to 30%, and in some facilities by up to 60%. Real savings depend on the facility's height, insulation quality, and the heating source capacity.

No, a destratification fan does not generate heat; it redistributes it within the facility. It achieves the best results when combined with air heaters (e.g., HC, FARMER, or S series), where it is responsible for bringing warm air from under the ceiling back down to the working zone.

HC-EC works well in typical production halls and warehouses where low operating costs and precise, smooth speed regulation are priorities. TORNADO is for larger volume facilities (airflow up to 10,200 m³/h, range up to 15 m) and locations where mechanical casing strength is key — the powder-coated steel construction withstands dust, moisture, and impacts typical of warehouse back-office environments better.

All models are designed for ceiling mounting. HC-EC units are installed using a swivel console or a Z-type hanger with a shock absorber. TORNADO units feature integrated mounting holes allowing for direct suspension on threaded rods. The Z-type hanger with a shock absorber is compatible with both models.

Yes, destratification fans can be used as ventilation devices to support air circulation even outside the heating season. In high-ceiling rooms, mixing air improves thermal comfort due to the light draft effect, although the device does not lower the air temperature itself. In this mode, the HC-EC model is particularly beneficial due to its smooth speed regulation, which allows for reducing RPMs to a level ensuring quiet operation while maintaining effective circulation.

Controller selection should be made based on the facility size and the method of integrating the destratification fan with the heating system. For typical installations, an HC manual thermostat, which switches the device on after exceeding a set temperature under the ceiling, is sufficient. In larger facilities where several units operate in parallel, programmable controllers from the HMI BMS series work better — allowing for centralized management of the entire system's operation and integration with a Building Management System (BMS).

Destratification fans do not require intensive maintenance — AC induction motors and EC motors are maintenance-free in typical operating conditions. Periodic cleaning (twice a year) of the rotor blades and casing to remove dust deposits is recommended to maintain nominal airflow performance. Accessing a unit mounted at a great height requires appropriate equipment, so maintenance work should be planned in conjunction with other facility service activities.
