Z-Chill™ Fan & Diffuser System

Z-Chill™ Fan & Diffuser System

Until now, there has been no economical solution to cooling large spaces; in both initial cost and operating expense.

HVLS fans have been utilized in the past to provide massive air movement at low speeds as a cost effective and energy efficient solution to help provide comfort.

However, during the high heat of summer and when the heat index soars above 90, the air becomes too warm for the fans to be able to provide any type of evaporative cooling, therefore, they are just moving around hot, humid air.

This leads to the fans being turned off and not utilized because the fans cannot deliver that much needed cool breeze to provide comfort and relief.

Go Fan Yourself® has the solution.

The patented Z-Chill™ Fan & Diffuser System allows the customer to remain both energy efficient and cost-effective.

Outfitting your facility with Z-Chill™ provides you the ability to distribute tempered air to enhance comfort, prevent heat stress and increase productivity levels.

How Does It Work?

  • The dual Z-Tech™ diffusers are specifically designed to equally distribute both filtered and conditioned air into the designed air distribution patterns of the Z-Tech™ (16, 20, & 24 FT) fans.
  • Dual Z-Tech™ diffusers are constructed of cold rolled steel and protected with powder coated paint.
  • Incorporates stepped Z-Tech™ internal prisms to equally split the incoming conditioned air.
  • The adjustable stepped Z-Tech™ vented louvers are designed to equally distribute the air across the entire circumference of the 5-blade Z-Tech™ stepped fan blade design.
  • The dual Z-Tech™ diffusers also features bottom perforations that are designed to equally disperse air spread in the center. This eliminates any dead zone beneath the center of the system.
  • The dual Z-Tech™ diffusers feature a closed cell thermal insulation design to prevent/minimize condensation on the outside of the entire unit.
  • Utilize existing rooftop A/C units or new OEM split air-conditioning units

Combined HVLS Fan and Conditioned Air Benefits

  • Provides tempered air and reduces relative humidity in the covered areas
  • Delivers evaporative cooling effect of air movement with cool and conditioned air
  • Eliminates condensation caused by temperature seasonal changes
  • Energy Efficient
  • Cost-effective operating expense
  • Open platform solution for HVAC & Mechanical contractors
  • Ease of installation for both existing rooftop and OEM split air-conditioning units

What Problems Does Hot Stale Air Cause?

An uncomfortable work atmosphere leads to low employee morale and lowered production rates.

  • According to a study conducted by a professor at Waseda University in Tokyo, for every degree rise in temperature above 77˚F, productivity drops by 2%

  • At 90˚F, your productivity goes down 26%

According to the Center for American Progress, the cost to replace an employee is almost 1/5th of the workers salary. High turnover can be extremely detrimental to a companies bottom line.

Indoor air quality and comfort are critical components of a healthy and productive work environment, and they can be significantly improved through the installation of a Z-Chill™ Fan & Diffuser System.

As the temperature/humidity index rises, heat-related injuries can occur.According to OSHA, heat-related disorders that can affect your workers are:

  • Heat Stress
  • Heat Cramps
  • Heat Exhaustion
  • Heat Stroke
Utilizing cooling fans/air-conditioning units are two of the recommended solutions for controlling your facility’s temperature.
