The New Viesa Holiday X

A multitude of innovations

The things that matter

12 volts +
low consumption =
Freedom

Freecamping, On the move, Anywhere

The Viesa Holiday X works at 12 volts, which means that it connects directly to the service battery, without the need for generators or inverters. Also, thanks to its very low consumption (only 1,29 Ah on average), it allows you to take full advantage of the cool air when free parking, but also during long journeys and even during the journey, thanks to the special patented anti-water-spill technology. With Viesa Holiday, there are no more limits. With Viesa Holiday X, there are no more limits.

Natural cool for everyone

The natural Viesa Holiday X system is suitable for all family members: adults, children, the elderly, as well as our animal companions. From now on, shopping, visiting a museum, or being away for a few hours will not be a problem: your pets will stay cool in their familiar environment and will have a peaceful life, without problems due to the heat or caused by traditional air conditioners. Just remember to leave enough food and water and not to leave them alone for too long.

A revolution: EPP

Expanded Polypropylene is a plastic material with exceptional characteristics that make the new Viesa Holiday X the ultimate evaporative air conditioner, in which light weight, strength, insulation and sustainability come together to provide unparalleled performance and comfort.

EPP: 100% Recyclable, 100% Sustainable

Crafted from fully recyclable materials, Viesa Holiday takes another step towards sustainability. Entirely gas-free, Viesa harnesses renewable energy sources like water and sun: a solar panel ensures electrical autonomy thanks to low energy consumption (optional, works without a panel). But that’s not all: by eliminating metal joints, Viesa Holiday becomes not only healthy for humans and animals, but also low environmental impact, for a healthier and more nature-friendly world.

Lightweight and Resistant

The Viesa Holiday X is the evaporative air conditioner for campers and vans that is the lightest on the market at ONLY 11.3 KG (about 40% less than the previous model).
It is chemical- and impact-resistant, absorbing shocks thanks to the memory quality of the material, which allows it to return to its original shape after deformation. EPP is used in the automotive sector, where it has also demonstrated resistance to bad weather.

Excellent insulation

EPP offers exceptional acoustic and thermal insulation, reducing external noise and preserving internal heat during the winter thanks to the thermal insulation it offers.
It reduces sound vibrations to ensure revitalizing rest, and is not affected by temperature variations, ensuring safety even on long journeys and in extreme climates.

Long-lasting filter

The new Viesa Holiday X filter has been completely revolutionized, both in shape and material: made of PP (polypropylene), it is durable and totally recyclable. Without the need for running-in, it guarantees cool well-being from the first time you switch it on. With a doubled lifespan, it only needs to be replaced after 4 summer seasons; in the meantime, it’s enough to clean the tank and replace the antibacterial agent every year.

Italian Design and Quality

100% Made in Italy

The Viesa Holiday X is designed, engineered and manufactured in Italy by ITALCOLVEN, based in Montemurlo (Prato), Italy. The attention paid to every detail is the sign of the quality that has always been our distinguishing feature.

Ultracompact

The Viesa Holiday X is now more compact than ever: its small size leaves more space available on the roof to install solar panels or other accessories for your motorhome or van.

Let there be more light

The Viesa Holiday X now features dimmable standard LED lights as standard. These new lights are not only more powerful, but also offer natural lighting that will definitively solve the problem of lack of light from the skylight. The increased brightness and more natural light create a welcoming and pleasant atmosphere, but above all a functional one.

New super-thin, super-flat cover

Open Sesame!

The internal cover has been shrunk from 7.5 cm to just 3 cm in thickness, allowing you to open doors without issues arising from a lack of space.
The biggest challenge was the engineering to reduce the height while increasing the air distribution.

New air diffusers adjustable from 0 to 90°,
for complete coolness.

Cooler, everywhere.

The new airflow design and the new lower mask design ensure optimum air distribution throughout the vehicle. Thanks to the adjustable air vents from 0 to 90°, the cool air can easily reach the high bed for optimal rest, and even the dinette, allowing you to enjoy your meals in the cool in total comfort.

We’ve thought of everything (really, everything!)

A small clarification: there is only one model of the Viesa Holiday X, so nothing changes in the size of the outdoor unit. What can change is the INTERNAL grille that can be adapted for different situations. Let’s take a closer look.

Standard: the classic one

This is the standard grille, i.e. the classic installation replacing a rooflight with standard dimensions of 40 x 40 cm.

What if you don’t have a rooflight? No problem: we advise you to speak with the authorized Viesa centre to evaluate the possibility of installing a docking opening on your roof.

MIDI, for those with panoramic skylights

This is the MIDI grille, bigger because it is used This is the MIDI grille, bigger because it is used to replace a panoramic skylight measuring 50 x 70 cm.
The two long flaps can be oriented in different directions to adapt to your rooflight.

Cover up, no more defects!

Is there a defect on the ceiling of the motorhome that you want to hide? A hole from old lights? Has an old leak left an unsightly stain?
We took care of it! A beautiful cover! A single long flap can be added to the standard mask, to be placed on whichever side you like, covering the defect while maintaining continuity with the original cover.

The power of evaporation evaporatiom:

how does Viesa Holiday work?

The operating principle of the Viesa evaporative air conditioner is based on the reduction of perceived temperature, that is, the temperature felt by our body.
This value is influenced by 4 different factors: the temperature of the environment, relative humidity, ventilation and the density of humidity.

The Viesa evaporative air conditioner acts on all four of these factors to create a condition of well-being directly on the person, rather than on the surrounding environment. This results in the evaporation of moisture on the skin, which has the effect of removing heat, essentially meaning YOU WON’T SWEAT.

The cooling process begins with the evaporation of water on the surface of the evaporative filter, which leads to a drop in air temperature. The cooled air is then introduced into the cabin with an optimal relative humidity between 40 and 60% (ideal for humans according to scientific studies) and with a very low density.

Stabilizing relative internal humidity is essential: excessive humidity can hinder or prevent the evaporation of sweat.

The low density (drops of only 0.002 microns) allows the water to be distributed over a much larger surface area, speeding up evaporation, a process also facilitated by the forced ventilation generated by the Viesa’s motor.

The Viesa Holiday is NOT a dehumidifier or a humidifier, but an evaporative cooler. It does not remove humidity but instead tries to stabilize it, and when it is too humid outside, it can make use of the external humidity to recreate the same cooling process.

For it to work correctly, unlike a compressor-based air conditioner for which you have to close yourself inside, Viesa requires you to always keep a window or rooflight open to ensure the air recirculation necessary for a fresh and healthy environment.
