What does WANDI Korea do?

WANDI Korea is the official Korean distributor of WANDI environmental and gas measurement instruments, operated by RS Korea Co., Ltd. We provide sales, calibration, repair, installation, and technical support for portable and fixed multi-gas detectors and air quality monitoring systems, exporting to more than 20 countries with over 5,000 delivery records.

What products do you offer?

We supply portable multi-gas detectors (EDW100, EDW500, Gas Tiger series), fixed multi-gas detectors (FIX800, FIX900, FIX-AP), air quality monitoring systems (FIX5000), and gas leak detectors (GLD series) for industrial safety and environmental measurement.

Which gases can be measured?

Our instruments measure oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), combustible gases (EX), carbon dioxide (CO2), ammonia (NH3), and volatile organic compounds (VOC), among other hazardous and combustible gases found on industrial sites.

Do you provide calibration and repair services?

Yes. Beyond product sales, WANDI Korea provides in-house and national certified calibration, repair, installation, and ongoing technical support. Calibration and repair requests can be submitted through the quote/calibration/repair pages on our website.

How can I get a quote for a gas detector?

You can request a quote directly through the quote page on our website or through a nearby dealer. Let us know your application and target gases, and we will recommend a suitable model.

In which fields are the products used?

They are used across a wide range of industrial sites including laboratories, factories and plants, hospitals, military facilities, livestock and wastewater treatment, and construction sites for worker safety and environmental monitoring.

TS Korea — Dry Ice Container CO₂ Asphyxiation Prevention with Real-Time FIX800 and FIX-DS Safety Management

Dry Ice Container CO₂ Asphyxiation Prevention — Real-Time Safety Management with FIX800 and FIX-DS

This case from TS Korea explains why real-time CO₂ measurement is necessary for dry ice freezer containers. Dry ice is widely used in storage and logistics operations, but as it sublimates, it releases carbon dioxide (CO₂). In confined spaces with limited ventilation — such as freezer containers — CO₂ concentration can rise rapidly, exposing workers to asphyxiation risk including dizziness, respiratory distress, and loss of consciousness.

Why Real-Time Monitoring Is Necessary, Beyond Portable Spot-Checks

Dry ice sublimation rate and resulting CO₂ accumulation can change rapidly depending on quantity, ambient temperature, and ventilation status
Traditional portable gas detector spot-checks before entry provide only a single point-in-time reading, missing conditions that develop during the work period
FIX800 fixed installation combined with FIX-DS display board provides continuous real-time CO₂ monitoring, with immediate visual alarm if concentrations rise during occupancy
This continuous approach is particularly important in freezer containers where ventilation is inherently limited by the cold storage function itself

Frequently Asked Questions

Why does dry ice generate CO₂ asphyxiation risk?

Dry ice is solid CO₂. As it sublimates from solid directly to gas, it releases significant volumes of carbon dioxide. In confined, poorly ventilated spaces like freezer containers, this released CO₂ can accumulate rapidly, displacing oxygen and creating asphyxiation hazards.

Why is real-time monitoring preferred over periodic portable detector checks for this application?

Portable detector checks provide only a snapshot at the time of measurement. Since dry ice sublimation and resulting CO₂ levels can change continuously based on quantity and ambient conditions, real-time fixed monitoring with FIX800 and FIX-DS provides continuous protection throughout the entire time workers may be present.

Why are freezer containers particularly susceptible to CO₂ accumulation risk?

Freezer containers are designed with minimal ventilation to maintain cold temperatures, which is exactly the condition that allows CO₂ from dry ice sublimation to accumulate to dangerous concentrations rapidly.

How can FIX800/FIX-DS systems be installed for similar dry ice storage applications?

TS Korea provides installation services for dry ice storage and logistics facility CO₂ monitoring systems, including site assessment for optimal detector and display board placement.
