A “worth” investment
OUR elaboration on data from “Energy savings in production facilities”, published by the Province
Administration of Bologna, Italy. The analysis considers an industrial facility with an overall area of 1.800 mq (400
mq offices). Both annual cooling and heating costs are considered with regard to three separate energy classes :
- D class (worst scenario), yearly costs equal to 33.504 euro;
- B.3 Class (intermediate), yearly costs equal to 12.936 euro;
- A.6 Class (best scenario), yearly costs equal to 5.616 euro.

PionAir technology
Blade design
Last generation brushless engine
Blades are made of strong, durable, lightweight
aluminum that varies in width along entire length
of blades. Blades ‘ contour and twist are designed
for maximum air movement. The specific blade tilt
increases airflow and reach of air movement from the
fan’s center in all directions in a conical shape.
Brushless DC motors are synchronous electric
motors which move around, or are “commutated”,
electronically. With many fewer parts that can wear
out or break and need to be replaced than in a
brushed motor. DC motors tend to be more reliable,
last longer, less noisy and be more efficient.
Robust mounting system
Resilient blade/hub connection
Utmost safety and stability are delivered via the
utilization of stabilizing cables, beam clamp and
sound motor housing solutions.
The joint effects of vibration-absorbing material and
rotationally balanced blade/hub reduce stress to the hub.
Blade/hub connection is designed for over 10 times the
force and stress generated by the HVLS Fan.
HVLS control system
Smart air management platform
Speed control is adjustable and operates in forward
or reverse modes. PionAir fans are controlled and
monitored either “on-premise” (via a touch screen
device) or remotely (via the internet). Installation of
the control platform does not require manipulation of
standard electrical housing.
The air management platform is used to “smartly”
coordinate, different fans to maximize the facility
overall performance and reduce energy costs.
Each fan can be operated and scheduled
independently and autonomously.

How we operate
1. Customers’ needs
Determine customers objective and technology
requirements (mainly related to cooling, heating,
air conditioning support, dispersing humidity,
circulating air).
10
2. Determine the space of concern
within the facility
This step consists of characterising the area of
concern in terms of its overall dimension, number of
people involved, multiple and differentiated subspaces’ specific requirements, obstructions (walls,
mezzanines, equipment).
3. Area of influence
4. Layout
This step encompasses the selection of size, type
and number of fans. Based on a scientific analysis of
the relationship between fan diameter, appropriate
air velocity and perceived temperature change.
The combination of “diameter”, “air velocity” and
“temperature change” univocally defines an “Area of
Influence”. Each PionAir model has its own Area of
Influence that increases in size as fan diameter does.
Finally, based on the activities carried out in former
steps, the process ends up in establishing fans layout
across the facility. Fan layout within the facility is
based on fan diameter and Area of Influence.
