Applications

CET provides solutions for 15+ applications. Take a look as some of those featured below.

Enclosed Parking Facilities

Unlike open parking lots, underground parking or parkades rely on a ventilation system to bring in fresh air and purge the vehicle exhaust buildup inside the building. If the facility is not ventilated properly, it can become a hazardous environment as vehicle exhaust from idling cars and slow moving cars collects in the enclosed area. Carbon monoxide is the most abundant of the exhaust fumes, but there is also the possibility for Nitrogen dioxide from diesel powered engines. To provide a safe, breathable parking facility and minimize energy costs associated with the operation of the ventilation system, a hazardous gas detection system is necessary.

Hospitals and Labs

Magnetic Resonance Imaging (MRI) machines use a powerful magnetic field to produce 2D or 3D images of the internal human body. Nuclear Magnetic Resonance (NMR) spectroscopy analyzes samples to identify their components at an atomic level. Compressed gases and cryogenic liquids (usually nitrogen, helium and sometimes carbon dioxide) are used to cool the superconducting magnets in both types of machines and also move samples in and out of NMR machines. If a coolant leak occurs, the hazardous gas can displace the oxygen in the room, creating a dangerous situation for the people inside the room. Continuous monitoring for potential oxygen deficiency levels ensures the health and safety of patients and staff.

Growing and Production Facilities

Greenhouse CO2 Monitoring System

Greenhouses and other types of indoor grow rooms provide a structure for growing plants in a controlled environment. To create favourable growing conditions, reliable heating, cooling and ventilation systems must be used. If these systems are not maintained or are not properly monitored they may cause serious hazards to human health and may result in the destruction of property.

Heating may supplied by sunlight, natural gas, propane gas, fuel oil, wood or electricity. Gas powered equipment produces carbon monoxide.

CO2 enrichment in greenhouses allows crops reach their full growth, development and yield potential. Enriching the air with CO2 can be done by means of the combustion of natural gas or using cylinders of liquefied compressed gas or a carbon dioxide generator. CO2 displaces oxygen and if a leak occurs or inadequate, faulty ventilation exists, it could cause an asphyxiation hazard. 

Indoor Pools

Indoor swimming pools provide exercise and recreational fun for all ages. In addition to complying with indoor air quality regulations, being able to detect a leak early can reduce costs that could be incurred from escaping gas and excess energy use.

Many facilities use chlorine and ozone to keep the water clean and sparkly. Chlorine is a common disinfectant used for water treatment programs and ozone offers excellent disinfection and oxidation properties. Ozone helps prevent the accumulation of deposits on pipes and increases the comfort of patrons by reducing red eyes, swimsuit fading and other chlorine-related issues. To help ensure the health and safety of patrons and facility maintenance workers, it is important to have a continuous gas detection system to monitor for leaks in the chlorine feed and storage room and the ozone generator room. 

CO2 is commonly used to maintain optimum pH levels in the pool water. While CO2 is a natural, non-corrosive gas and in low concentrations is not harmful, in high concentrations it is toxic and it can displace oxygen, causing rapid asphyxiation and death, especially in a confined area like the CO2 gas cylinder storage room.

Water Treatment Plants

A waste water treatment facility is a wet maze of rooms, pipes, pumps, wells, chambers, concrete tanks and settling basins. Each treatment stage the wastewater goes through involves hazardous gases that may already be present, are produced, or are added to complete the process.

The most common gases found in this type of facility are hydrogen sulphide, methane, ammonia, carbon monoxide, chlorine and oxygen deficiency. Some facilities might also use ozone, chlorine dioxide or sodium hypochlorite with the chlorine during the sanitization process and sulphur dioxide is often used at the end to de-chlorinate the water.

To ensure the safety of the workers, equipment and facility, every area presenting a gas hazard should be monitored, including the gas storage rooms, ozone generator room and any room that gas passes through. In the larger, open areas, a fixed gas detection system is suitable; in confined spaces that operators enter and where gas may be present, portable gas detectors are more appropriate.

Gas Detection System Interaction with VFDs

Flow Tech also represents ABB variable frequency drives (VFDs). The below video explains how variable frequency drives can improve the energy efficiency and reliability of fans associated with CET’s gas detection systems.
