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 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.
