Antifreeze tower: VITICULTURE AND ARBORICULTURE
Tree frost protection: protect your orchards against spring frost for the long term with a powerful, mobile solution specially designed to protect crops against frost.
Spring frosts are one of the main risks in arboriculture today. A single night of frost can jeopardize an entire production season, impacting yields and weakening operations for a long time to come.
The V5 anti-freeze tower, developed in collaboration with arboriculturists in the Tarn-et-Garonne region, provides a high-performance solution for protecting crops against frost, thanks to a system combining powerful air circulation and integrated heating. VENTIGELâ„¢ V5: high efficiency for your orchards!
"A dry plant can withstand frost for 40 minutes to 1 hour, whereas a wet plant can't last more than 10 minutes." — CTIFL Publication
How does the VENTIGEL V5 antifreeze tower work?
The V5 anti-freeze tower is a system designed to protect orchards from radiant frost. The system works on two complementary principles:
✔ High-performance air circulation
With a flow rate of 60,000 m³/h, the primary objective of VENTIGEL™ is to ventilate early enough with a powerful jet of pulsed air, thus drying out plots and preventing the formation of condensation on plants. It also enables the redistribution of rising warm air during a frost by radiation.
✔ Integrated thermal input
The two 110 kW on-board heaters enhance the system’s efficiency by supplying heat to the protected area when temperatures continue to fall, thus optimizing protection.

WHY CHOOSE THE V5 FOR YOUR ORCHARDS
✔ Materials and design
VENTIGELâ„¢ V5 is manufactured with materials suitable for outdoor use even in demanding climatic conditions. This choice guarantees optimum durability.
As for power, the VENTIGELâ„¢ V5 is powered by electricity for the ventilation and rotation functions and by diesel fuel for the heating function. Maintenance-free ventilation without a combustion engine.
✔ Proven effectiveness
The VENTIGELâ„¢ system acts on two levels to limit the damage caused by radiative freezing:
- Dries out the air around sensitive buds
- Reduces frost formation
- Raises the temperature evenly across the treatment area
- Effective on 3 to 4 hectares, easy to use.
✔ Easy to install
VENTIGELâ„¢ V5 is trailer-mounted with a telescoping mast, allowing for quick setup between rows of trees, optimal maneuverability, and adaptability to different orchards. Low power consumption; no visual impact when stowed.
What tree crops does the frost protection tower protect?
Grapes
Apples
Stone fruit
Pears
Citrus
Kiwi
But also many other crops can be protected by the VENTIGELâ„¢ V5 antifreeze tower.
Advantages of the V5 anti-freeze tower for arboriculturists
The VENTIGELâ„¢ V5 frost protection tower offers many advantages over other frost control solutions such as candles, heating wires or some sprinkler systems. Our VENTIGELâ„¢ V5 antifreeze towers offer high efficiency.
Its main assets include:
- Reliable protection for buds and flowers: by keeping temperatures above critical thresholds, the anti-freeze tower effectively limits production losses and preserves the harvest.
- Optimized yields: by reducing the impact of spring frosts, the system helps maintain fruit quality and secure harvest volumes.
- Reduced night-time logistics: unlike candles, which require considerable manpower for lighting, monitoring and extinguishing, the anti-freeze tower considerably simplifies the organization of interventions.
- No noise pollution: Much quieter than other fan-based protection systems, it can be positioned close to dwellings.
- No visual pollution and easy installation: The antifreeze tower can be reused from one season to the next. Between two seasons, it can be stored in a shed until it is needed again.
- Low maintenance: Very little maintenance is required.
- Environmentally friendly: Low energy consumption.
- Cost-effective: No civil engineering required; a few euros per hour for electricity.
