HVLS Fans Help Reduce Heat Stress

Hidden Costs of Heat Stress

Comfort isn’t the only thing sacrificed when employees experience heat stress. Fogged-up safety glasses, sweaty palms, dizziness and reduced mental capacity resulting from heat stress can all lead to accidents on the job with potentially tragic consequences. Studies prove that losses add up when workers experience heat stress. 


Heat Stress Studies
OSHA Standards 

OSHA’s general duty clause states that an employer has the obligation to provide a workplace free of hazardous conditions that are likely to cause death or serious physical harm; this includes heat-related hazards. 

What Helps Prevent Heat Stress? 

Environmental factors can be adjusted to help the human body maintain a normal temperature and control heat stress. For indoor work environments, one recommendation from OSHA is to increase ventilation and use fans to increase the air speed over workers.   

How Do HVLS Fans Lower the Effective Temperature? 

An air speed of two to three miles per hour creates an evaporative cooling sensation of 7°F to 11°F. A warehouse with an effective temperature of 84°F can be dropped to 73°F by adding HVLS fans. This cooling effect can increase worker productivity by 35%. 

HVLS fans can help prevent heat stress and create a safer working environment. The additional benefits of providing a safe and comfortable work environment include increased productivity, reduced costs, reduced employee turnover, and improved employee morale. roviding a safe and comfortable work environment include increased productivity, reduced costs, reduced employee turnover, and improved employee morale.

Sweating Slab Syndrome

Sweating Slab Syndrome

Concrete "sweats" when moisture collects on the surface through condensation. This creates slippery conditions that pose a danger to workers, equipment, and products. Learn how HVLS Fans can address this problem.

Outdoor Auditorium

Beat the Heat – Everywhere! 

HVLS fans are great for warehouse applications but they are also used in hundreds of other non-industrial applications too. Some include outdoor auditoriums, restaurants, convention centers, religious facilities, and health clubs. You can use HVLS fans almost anywhere. Read more.  

Caljan Performer Telescopic Conveyor


Caljan Telescopic ConveyorSpeedy Unloading Increases Liquidity

The Need: A textile supplier in Brazil wanted to shorten their lead time from receiving goods to invoicing. They determined the key was to increase unloading capacity.

The Solution:  Incorporating Caljan Telescopic Conveyors into the goods-in process increased the unloading capacity by 150%! Customer orders are now invoiced just hours after the container arrives — a significant reduction from the three days required previously. Read more and access the case study here.
