Protective coveralls

Today, gas detection systems are essential in wineries to prevent the risk of asphyxiation from CO2 and lack of oxygen during fermentation, devatting and tank cleaning. At e-viti, the "Gas Detection" range is aimed primarily at wineries, cooperative wineries and local authorities wishing to ensure the long-term safety of their teams and technical premises.

What are gas detection devices used for?

In winemaking, CO2 is massively produced during fermentation, and easily concentrates at the bottom of vats, in pits, stairways or poorly ventilated areas, with a sudden risk of asphyxiation for operators. Gas detectors provide real-time alerts when critical thresholds are exceeded, through audible, visual and vibrating alarms, and trigger ventilation or evacuation of at-risk areas if necessary.

This equipment is part of an overall prevention approach: systematic control before tank entry, monitoring of confined areas, making premises safe (warning lights, fixed detectors controlled by fans). They help you meet your occupational health and safety obligations, and protect both permanent and seasonal employees during the harvest.

Types of gas detection equipment available from E-viti

Portable CO2 detectors

Designed to follow the operator around the winery, portable CO2 detectors are the basic tool for safety during winemaking.

• iGas portable CO2 detector: compact infrared CO2 detector, real-time display, audible, vibrating and visual alarms to alert the user immediately.
• Gasman portable CO2 detector: a reference widely used in wineries and cooperatives, with a measurement range adapted to the risks of winemaking, multi-segment alarms and excellent IR sensor stability.

These devices can be attached to a suit or used for spot checks, particularly before entering a tank or a poorly ventilated room.

Portable single-gas detectors (O2, CO2, toxic)

Single-gas detectors can be used to target a given gas, as a complement or alternative to portable CO2 detectors.

• Senko SGT single-gas detector: compact device for monitoring a specific gas (depending on version), easy to handle by seasonal staff.
• BW SOLO single-gas detector: modern, robust individual detector designed for continuous monitoring of a single gas, with highly visible alarms.
• Portable O2 detector: essential for detecting oxygen-depleted atmospheres in tanks or confined spaces, even in the absence of high CO2 concentrations.

Portable multi-gas detectors

For sites exposed to several risks (CO2, O2, toxic or explosive gases), multi-gas detectors combine several sensors in a single device.

• MGTP portable multi-gas detector: a versatile solution for simultaneous monitoring of several gases, suitable for modern wineries and complex installations.
• TETRA + portable multi-gas detector: a robust detector designed for harsh environments, with distinctive audible and visual alarms and configuration options to suit the gases monitored.

Particularly suited to large wineries, cooperatives and multi-process food processing sites.

Fixed CO2 and CO2/O2 detection

Fixed detectors continuously monitor an area of the winery (tank foot, vat room, pressing area, CO2 storage room) and trigger collective alarms.

• Fixed CO2 detector: installed in a station, it warns when CO2 thresholds are exceeded, and can control a fan, the opening of hatches or a centralized alarm system.
• CO2 / O2 detector: CO2/O2 combination to monitor both carbon dioxide accumulation and oxygen deficiency, particularly useful in very confined areas.

These fixed solutions form a real safety system at building level, and complement the individual protection of operators.

Ventilation and signalling

In addition to detection, e-viti offers equipment for extracting gases and clearly signalling the danger to the team.

• Tank CO2 extractor fan: transportable centrifugal fan for rapid air renewal in tanks from 10 to 120 hl, usable for extracting stale air or blowing in fresh air.
• CO2 warning light: a traffic light or dedicated light signal, providing instant indication of the CO2 risk level at the entrance to a room or staircase.

These devices make prevention easier to understand and encourage the right reflexes before entering a high-risk area.

Detector inspection and maintenance

The reliability of detection depends on regular inspection and calibration.

• GASMAN portable CO2 detector inspection: Gasman detector inspection and adjustment service to ensure accurate measurements and correct alarm triggering.
• TETRA+ portable multi-gas detector inspection: metrological inspection and maintenance service for your TETRA+ multi-gas detectors, recommended at least once a year.

These services enable you to keep your equipment in line with manufacturers' recommendations and good risk prevention practices.

How do I choose my gas detection equipment?

The choice depends first and foremost on the configuration of your winery: number of vats, presence of buried areas, air circulation, number of employees and periods of high activity (harvesting, tapping, cleaning). For an estate or small winery, one or more portable CO2 detectors combined with an in-vat CO2 extractor fan are often an effective basis.

Cooperative wineries or structures welcoming the public (tours, schools, local authorities) will benefit from a combination of portable detectors for staff, fixed CO2 or CO2/O2 detection in the most exposed areas, and warning lights visible from a distance. Finally, the question of maintenance is key: opt for robust equipment, with stable infrared sensors and a clearly defined annual inspection plan to maintain a high level of safety over time.

Why choose e-viti for your gas detection equipment?

E-viti brings together on a single platform complete solutions for gas risk prevention in viticulture: portable and fixed CO2 detectors, O2 and multi-gas detectors, ventilation, signalling and control services. The products offered are selected for their suitability to the real-life conditions of wineries (humid, dusty, shocking, poor lighting, noisy environments).

You benefit from dedicated support in sizing your system according to your configuration (number of tanks, volumes, buried areas) and your regulatory and organizational constraints. In addition to detectors, e-viti also offers a full range of associated PPE (respiratory protection, signalling, lone worker equipment), to help you build a coherent, operational prevention policy for the risks of CO2 and oxygen deficiency in the cellar.
