Xgard Gas Detectors

Crowcon is a global leader in designing and manufacturing gas detection technology and equipment. The company has been in operation for over 40 years and is consistently building upon its products. By integrating modern technology with the demands of the modern workplace, Crowcon has developed a line of gas detection devices and monitors that lead the competition. The Xgard range of gas detectors is a product of Crowcon s successful integration and technological advancements. With a wide range of sensor types and available accessories, the Xgard series is suitable for all worksites and is customizable enough to fit any needs.

Tough and reliable

The Xgard series of fixed point gas detectors is incredibly durable and reliable. The casings and materials, including weatherproof caps, are designed to protect the equipment from the harshest environments. The detectors are made from a variety of materials depending on the model: glass reinforced nylon, aluminum with polyester coating, and 316 stainless steel.

Variety of sensors

The fixed point gas detector offers a wide range of sensors for to suite almost all applications. The Xgard range of gas detectors is available in three models to meet varying worksite needs: flameproof, intrinsically safe, and safe area formats. Additionally, Xgard offers different types of fixed point gas detectors within these three models:

• Xgard Type 1- Intrinsically safe toxic and oxygen gas detectors
• Xgard Type 2- Flameproof toxic and oxygen gas detectors
• Xgard Type 3- Flameproof flammable gas detector
• Xgard Type 4- Flameproof high temperature flammable gas detector
• Xgard Type 5- Flameproof flammable gas detector with 4-20mA output
• Xgard Type 6- Flameproof thermal conductivity type gas detector
• Xsafe- Safe area flammable gas detector

Cost efficient and highly effective

With quick and easy installation and maintenance, the Xgard series is able to keep costs at a minimum. The replacement sensors, for example, are simple to replace by merely plugging them in. The replacement parts are also readily available and compatible with all Xgard models, thereby reducing the amount of required spare parts that are stored in the facility. Additionally, the sensors have two times the typical life spans of similar sensors in the industry. With a 2 year life span, worksites can expect to cut their sensor replacement costs in half. For worksites that require slightly more customization, Crowcon offers compatible accessories for the Xgard series such as sampling applications, remote gassing applications, spray deflectors, sun shields, weatherproof caps, collector cones, flow adapter, and accessories adapter.

Xgard also has flexible installation options. The unit is designed for either wall or ceiling mounts, and users will not need to purchase additional equipment for mounting. For more complex installation needs, users can purchase accessories.

Specifications

Each model is approximately the same size with dimensions of 6.1 x 6.5 x 4.3 inches and weighing approximately 1 or 2 pounds. The battery type, electrical output, and power requirements vary based on the sensor type.

Gas-Pro TK Dual Range Portable Monitor by Crowcon

Hydrocarbons stored in inerted environments create a particular flammable gas detection challenge, whether during transport at sea or storage on shore. Gas-Pro TK dual-range portable monitor is designed for use in this specialist environment where standard gas detectors just won't work whether tank purging or gas freeing.

Tank check functionality summary

• Tank specialist - Designed to perform in the challenging inerted tank environments
• Dual IR sensor - Detects the spectrum of possible flammable gas concentrations from high %vol to low %LEL. Auto-ranges, switching between %LEL and %vol as gas concentration demands. Notifies you of auto-ranging as it happens.
• Monitors oxygen - Know when it's safe to load fuel. Know when it's safe for operators to enter
• High H₂S sensor option - Understand possible risks if gases vent during purging helps inform you of potential risk from pyrophores
• Alarms disabled in tank mode - High gas levels are to be expected, so alarms can be misleading and annoying
• Automatic flow plate recognition - Integrated pump turns on as soon as the flow plate is applied. Tank samples can be drawn from up to 98.4ft.

Safety

• Mode indication - Clearly indicated when in Tank Check mode, avoiding potential confusion
• Confirmed alarm status - In Tank Check mode, alarms are disabled. You must acknowledge this before you can proceed
• Simple single button operation - Simple one-handed operation. Easy to learn and remember. Easy to use while wearing gloves
• Light - At 12oz, it is light enough to clip to your belt, overalls, or a Gas-Pro harness, so it's easy for the technician to keep with them during their working day
• Black - Part of the Gas-Pro range of detectors, Gas-Pro TK units are black to avoid any possible confusion

Personal monitor functional summary

• Personal gas detector - Gas-Pro TK has full Gas-Pro functionality, so can double up as a personal detector, as required. Full range of alarms are enabled: audible (>95dB); visual (red and blue flashing LED); tactile (vibrating).
• Confined space preentry check function - Assists you through the pre-entry check process
