PRESS system

Pressostats such as balloons and pressostructures are modern sports roofs without the
classic rigid iron supporting structure. The lack of a steel structure makes it possible to
easily cover tennis courts and playgrounds during colder periods and to play in the open air
outdoors during warmer seasons, being able to be assembled and disassembled more easily.

The Pressostatic Energy Saving System “Pressostatic Energy Saving System” is the
solution we propose. Born from ‘experience in energy saving and knowledge of
pressostatic structures gained over the years..


ENERGY SAVINGS

Achieving energy efficiency is one of the most important goals for entrepreneurs: reducing
consumption means not only containing costs but also improving in organization and in service
offered.

Energy efficiency programs can be of various types, but they all start with the
diagnosis of energy consumption, which is necessary to establish the different actions that can be implemented.
It is these actions that will lead toward the upgrading of sports facilities,
choosing to replace, for example, old heating systems with new motors with high
efficiency, thus obtaining better performing and less polluting energy classes.

CRITICITY AND SOLUTIONS

The main characteristic of pressure structures is the fact that they are supported by the pressure
atmospheric interior. For this reason they are also called pressostatic balloons.
The pressure difference between inside and outside is very few PA: in fact, 150 PA are sufficient
to support any structure. This difference is maintained by one or more
inflation, integrated with the heating system.

When the balloon is pressurized, the system does not have to operate at maximum power, but
only maintain internal pressure. On the contrary at the presence of special weather conditions,
such as wind and snow, the engine will have to work at full power to increase the internal pressure and
keep the structure safe.

So far, to cope with the weather conditions and leakage present, modules have been provided that are
heavily oversized and unable to adapt to various conditions of use, since the motors
used do not have the ability to modulate their rotational speed and power input,
resulting in substantial and constant power consumption throughout the 24 hours.
Constant use of motors at full power results in higher electricity costs,
greater noise pollution and higher maintenance costs, wearing out faster
mechanical parts.

To limit/eliminate all these inconveniences, the PRESS system uses an Inverter that can modulate
the speed and power of the motors, thanks to an electronically managed smart system.
Thanks to sensors inside and outside the PRESS, the Inverter regulates the work of the systems,
even reaching savings of 70 percent (savings depend on the type of motor and how many years
is in operation).

According to feedback provided by sports clubs, which have already adopted the PRESS system,
the investment pays for itself after one or two seasons of operation, thanks to lower
energy costs.

The PRESS SYSTEM

The PRESS system is an excellent tool for sports clubs and others to decrease consumption and
offer better service.
In addition to switching to electronic motor control using the Inverter, the advice is to
use high-efficiency motors, considering whether to replace the old motor with a new
generation.

Other necessary actions are:
– Optimize the mechanical transmission;
– Change the transmission ratios to obtain maximum efficiency from the fan;
– Insulate the structure, to avoid unnecessary air leakage.
An industrial controller controls the Inverter according to indoor and outdoor conditions,
lowering and increasing the motor speed and consequently consumption.

PRESS 4.0

Press 4.0 was created as an upgrade for the PRESS system, allowing the PRESS system to be connected
to our cloud.
It provides real-time monitoring with cell phone alarms, ex: snow, power failure,
engine blockage.
It allows you to set the speed remotely, having an always up-to-date system that keeps
historical statistics and can be integrated with the Gestennis service.

Gestennis is another service offered by our company.
