Crowcon CellarSafe Gas Detector Helps Athletes Train Safely in Artificial Mountains

Gas detector ensures constant O2 and CO2 levels in enclosed chambers

Crowcon’s CellarSafe O2/CO2 gas detector and control system is being used to monitor the level of the two gases in unique ‘artificial mountains’ – enclosed endurance training chambers designed to simulate depleted oxygen levels at high altitudes. The chambers are manufactured by German company Höhenbalance AG.

Generators filter O2 molecules out of the air feeding the chambers, resulting in concentrations of 14% or even lower, depending on the settings. In this way the ‘altitude’ can be simulated up to 6000m.

While training in the chamber an athlete will breath out a lot of CO2 which, if not monitored closely, can build up to dangerous concentrations. The compact CellarSafe is therefore equipped with both O2 and CO2 sensors and constantly monitors the concentration of the two gasses in the chamber. O2 and CO2 levels are transmitted to an adjacent control unit which adds or removes O2, depending on the demand. In this way a safe, constant ‘altitude’ is maintained for the athlete.

“Minor variations in O2 concentration are not immediately dangerous for the athletes, but reliability and accuracy are nevertheless our main concerns to achieve optimal training conditions,” said Christian Blauth, a sports scientist and member of the Höhenbalance AG management team. “Crowcon, which is well known as a leading supplier of gas detection equipment, was therefore chosen to ensure the required safety levels.”

The training chambers are not just used by athletes but also by people preparing for climbing or trekking in mountain regions, preparing their bodies for strenuous activities at high altitudes. Research has also shown that high altitude training supports weight loss programs and helps to reduce stress.

The CellarSafe gas detector also has many other applications. It is most commonly used in wineries, breweries, food processing facilities and pub cellars to monitor and control CO2 levels. Long term exposure to as little 0.5% volume of CO2 represents a toxic health hazard and concentrations greater than 15% volume can lead to death. The CellarSafe was specifically designed to warn personnel of these hazards.

Simple to use, the CellarSafe not only continuously monitors CO2 and O2, but can also be connected with control systems to automatically turn on ventilation fans, trigger alarms or, as in this application, adjust O2 concentrations to within set parameters. It has a clear, easy to read backlit display of gas readings, a bright LED warning light and a loud built-in alarm. Ingress protected to IP65 against dust and water ingress, it can operate over a wide temperature range.

The ri-scope® L range combines energy efficient LED technology with a long lasting, light-weight lithium-ion (Li-Ion) battery to ensure sustained, high-power performance and significant cost savings. Li-Ion batteries have the benefit of achieving a considerably higher charging capacity and longer lifetime than regular batteries and provide sustained high performance for up to 1200 charging cycles.

Riester also recently launched its heotronic® technology for instrument handles. This new patent pending technology makes it possible to power both LEDs and conventional bulbs electronically. This means that all ri-scope® L instrument heads only need one handle, no matter which kind of illumination is selected. 100% light output is guaranteed immediately after a slight turn of the electronic switch and it is possible to regulate light intensity very smoothly in both directions. An automatic turn-off function after 120 seconds guarantees that LEDs, bulbs and the Li-Ion rechargeable batteries are conserved and can be used as long as possible.

With this universally unique combination of LEDs, Li-Ion rechargeable batteries and rheotronic® technology, Riester now offers the most reliable diagnostic instruments with the longest lifetime on the market. All ri-scope® L instrument heads can be used with C- or AA-handles, making them portable, or with the Riester diagnostic wall mounted station, the ri-former®.

The new Chlorometer is very easy to use, with just four intuitive buttons and a menu that uses universal symbols instead of individual languages on its LCD display screen. While its small size (150 x 65 x 40mm) and light weight (200g) make the unit ideal for in-field and on-site testing, its accuracy (± 0.02 @ 1 mg/l) makes it suitable for bench use in both laboratories and water treatment plants. Test ranges are 0.01-5.0 mg/l for Free and Total Chlorine levels, and 1-250 mg/l for Chlorine HR concentrations.

With an IP67 rating, the instrument is robust and waterproof, and can be supplied in either a hard or soft carry-case that also holds a store of reagents and test tubes. It uses only 2 AA batteries, giving around 5,000 readings thanks to its low power operation and auto switch-off setting when not in use. The zero reading is held in memory between uses, or can be reset for each test, while the new narrow band wavelength filters provide unparalleled wavelength accuracy for a handheld monitor.

Petroleos Mexicanos (PEMEX) Chooses FAITH Partial Stroke Testing Systems from Netherlocks for Offshore Facilities

Petroleos Mexicanos (PEMEX) has chosen Dutch industrial safety specialist Netherlocks B.V. to supply its FAITH partial stroke testing systems for three offshore facilities in the Gulf of Mexico. The FAITH tests ESD (emergency shut-down) valves with a partial stroke operation, therefore not interrupting production during the test.

PEMEX is Latin America’s largest enterprise, and one of the few oil companies that operates the entire production chain from source to market, with a yield of over 3m barrels per day in 2006. The company has used Netherlocks safety equipment for several years, and continues to rely on the simplicity, reliability and functionality of its mechanical safety systems for critical applications.

Partial stroke testing is of major importance to end users, as an important safety step to ensure that an ESD valve will operate as intended, when needed. All valves can become worn or stuck over time, so something as vital as an ESD must be tested frequently in order to meet SIL* standards. A partial stroke test enables testing without halting process flow, meaning tests can be carried out more easily and more often, which should then also create a more reliable ESD system.

The mechanical nature of the FAITH system ensures that the specified degree of opening (test angle) is not exceeded during the test. The Netherlocks device can also be used to block the actuator to perform maintenance on the ESD during production. Instead of relying on a potentially complex electronic system for a simple – but vital – operation, the FAITH is itself a simple, maintenance-free mechanical device that can still offer electronic feedback with optional added components.

*Safety Integrity Level
