4-Way Inspection Services’ factory trained technicians have been installing, commissioning, testing, calibrating, and replacing various fixed gas detection systems for various applications in and around the Edmonton region as well as throughout all of Alberta, BC, Saskatchewan and the Northwest Territories since inception. We service all makes and models of fixed gas detection equipment out on the market today such as Honeywell, Armstrong, Critical Environment Technologies, QEL, AirTest, Greystone, Veris Industries and more.
About Gas Detection:
Life safety as well as energy efficiency are the main reasons for maintaining these gas detection systems. Frequent calibrations as well as regular maintenance both play an important roll to ensure optimal performance of the gas detection system. Every manufacturer has their own calibration frequency and 4-Way Inspection Services can advise you as to how frequent your specific equipment needs to be calibrated. You may be surprised that your system is being calibrated more frequently then needed resulting in higher unnecessary costs.
Different types of gas sensors have different ranges of life expectancy. Over time, these sensors begin to “drift” becoming less accurate and creating a safety concern. They can “drift” and result in the sensor being less sensitive which results in the ventilation system not starting when it should. This creates a dangerous environment as high levels of gas may be present without even knowing. The alternative is that the sensors can “drift” becoming more sensitive resulting in the ventilation equipment starting up too soon and too frequently. This results in higher energy costs and wear on the associated ventilation equipment. Calibrating the sensors to that optimal level eliminates both scenarios and ensures the equipment is running efficiently as per the manufacturers specifications.
Ensuring that your system is running correctly and efficiently results in significant cost savings. For example, a gas detection system can control a parkade’s ventilation system. When a pre-set gas concentration is reached, the ventilation system activates which in turn exhausts the contaminated air and brings in fresh air to replace it. The cost to run these fans can accumulate quickly. In the winter season, the cost to run this system significantly increases as the warm air that is being removed from the parkade is being replaced with cold fresh air which needs to be heated up by the make-up air unit. By ensuring that your system is running correctly, less frequent ventilation system start-ups will provide a substantial savings on energy costs. Reduced wear on the various ventilation equipment such as the motors and fans is also a benefit to less frequent start ups as it is hard on the equipment every time the system is activated.
