REFRIGERATION & ICE THE DIFFERENCE BETWEEN Residential and Commercial Gas Detectors - It's Not JUST THE COST C ommercial gas detectors can be as much as 100 times the cost of residential gas detectors, making the residential models financially tempting. However, there are some important differences in performance, diagnostics, configurability and regulatory standards between the two that make using residential models in applications other than home environments insufficient, dangerous and unlawful. Enclosures Residential detectors are built to withstand standard household temperatures and activities, which means they are typically made of regular, low-impact plastic, are not waterproof or IP-rated and are mounted on the wall and easily forgotten about. Commercial gas detectors are designed to endure a variety of conditions from hot to cold, dust, water and potential damage from vehicles, machinery or vandalism. These enclosures are typically rugged, waterproof, IP-rated and locking and will last for years in mild to harsh environments. Ice arenas are cooler By Rebecca Erickson, Critical Environment Technologies Canada, Inc. environments with melting ice, flying pucks and equipment that could come in contact with a device mounted in the ice resurfacer/lift truck/floor sweeper/ etc. parking area. The durable enclosure of a commercial detector will sustain such abuse. Functionality/Configurability Residential gas detector sensors are tested before they leave the manufacturing plant and do not require calibration or changes to their pre-programmed settings after they are installed. They are essentially maintenance free. The sensor technology is basic because specialized features are not required for simple gas monitoring in a house. The protocols often follow an OFF/ON pattern whereby the sensor takes readings at intervals. The alarm is set on a timed basis, and in the event there is a gas leak, it will alarm only after a time-weighted duration of over 60 minutes. Meaning, if the gas reading is above the average exposure allowed over an eight-hour period for longer than an hour, then the alarm will sound. (Of course, if the gas reading skyrockets over a certain level, the alarm will sound sooner.) Commercial gas detectors are calibrated before they leave the manufacturing plant and require a regular maintenance schedule that includes bump tests and full calibrations to ensure the device is working properly and accurately sensing gas levels. The sensor technology is required to be more advanced because of the demands of the environments the sensors are used in, the information needed to be obtained from them and the functions they need to perform. Common features of commercial gas detectors are relays and multi-level alarm functionality. When a gas level triggers an alarm, the relay can be configured to perform a safety function such as turning on or off a ventilation system, activating a remote strobe or horn, or alerting emergency services. They may also be capable of networking with each other, communicating with a building automation system and data logging. Ice arenas have multiple gas hazards requiring different gas detectors mounted at different heights in several locations throughout the facility. Ammonia is commonly used in the ice chiller mechanical room, and if a leak were to occur, it would become a corrosive, toxic gas. At the ice surface level, FACILITY FORUM | 41
