Ambulance Stations
Ambulance and associated vehicles may have gasoline or diesel engines.

Gasoline engines will have carbon monoxide (CO) concerns and diesel engines will have nitrogen dioxide (NO2) concerns. The EC-Gold Dual series offers both gas sensors in one compact unit. The alarm levels are adjustable to your local code requirements and on-board relays can operate ventilation fans. A buzzer with silence is standard on all units should levels continue to rise after the fans have initiated.


Arenas
Propane powered ice re-surfacers (Zamboni's TM) pose two potential hazards in arenas: Propane leaks in the tank storage area and carbon monoxide exhaust in the rink and adjacent public areas. Ice chiller equipment rooms will also require ammonia or refrigerant monitoring systems and may be subject to local CSA or AHSRAE code requirements. We can help.

Our 4300-PG can scan multiple gas and sensor types. If your chiller room is subject to the refrigeration code, Our 4200-IR is specifically designed for you to meet code.


Automobile Dealerships
There two main areas to look for monitoring in a dealership; The customer drive-thru bay and the service bays.

In the drive–thru, our Gas Alert Dual will provide a compact and professional package with display and relay interface for fans. A buzzer is included should concentrations rise to higher levels after the fans have attempted to clear any carbon monoxide.

In the service bays, we suggest our Gas Alert Max with EC-Gold sensors. This offers a central panel to control the fans with up to 20 low-cost sensors mounted in key locations of the service bays. Sensors are typically mounted along the workbench wall every 60 to 80 feet.

Battery Charging Area
Hydrogen gas can be a by-product of charging batteries.

Hydrogen sensors should be considered for monitoring combustible gas at the % LEL concentration. Mount the sensor above the batteries near the ceiling and easily accessible for routine testing.

Boiler Rooms
  • There are two main target gases in a Boiler Room. Carbon Monoxide from the gas fired heaters and natural gas leaks.

    Most typical monitoring is for carbon monoxide monitoring and your local regulations may have a code requirement addressing this. The the EC-Gold Dual can used in the Boiler Room. This is a compact unit with on-board CO sensor, relays, and a buzzer alarm. A combustible sensor can be added to this model now or in the future should you need to monitor for natural gas.


Bus Garages
There can be several target gases in a Bus garage storage or maintenance garage

· carbon monoxide from gasoline engines
· nitrogen dioxide from diesel engines
· hydrogen from Hydrogen storage leaks
· combustible gases from gasoline and oil leaks in service pits

A typical system starts with the 4300-PG but we can offer a variety of models depending on the quantity and type of gases being monitored.


Chemical Storage
Both combustible and toxic gases can be found in chemical storage areas. Typically, explosion proof sensors will be used in conjunction with the 4200-IG control panel. The panel is mounted in a non-classified area and the sensors are mounted near the danger source. Use caution when considering sensor placement. Some gases are heavier than air and some are lighter. The gas may also be inert and require an Oxygen deficiency sensor.



Chiller Rooms

Refrigerating machinery rooms are typically subject to specific code guidelines indicated by ASHRAE Standard 15 or CSA Standard B52. Check your local code requirements.

The Arjay 4200-IR is designed to meet the code requirements of ASHRAE and CSA for refrigerant leak monitoring. Standard features include all audio, visual, and operator interface needs. As well, our standard panels include ventilation fan and chiller override switches on our panels so you don’t have to source them separately.

As a minimum for code, you will need one main panel, one remote panel (one outside each entranceway), and one infrared sensor (our panels can monitor up to 8).




Fire Halls

Fire Stations can be of special concern. WIth both diesel and gasoline vehicle storage bays, nitrogen dioxide and carbon monoxide should be monitored.

The EC-Gold Dual is designed for these applications with the onboard CO/NO2 combo plus an available remote CO or NO2 input for a sensor in a remote bay.

It is important to note that the sleeping areas, being adjacent to the vehicle storage areas, should be monitored for CO using residential code approved gas detectors that are available from retail outlets.




Forklifts

Propane forklifts can emit carbon monoxide and the areas where these are used should have CO monitors in place. The Gas-Alert Max is a common choice for warehouses due to the low cost and ease of use. A propane leak monitor should be considered in the tank storage area

If the forklifts are battery operated, consider hydrogen monitoring in the battery charging areas. The EC-Gold Dual is ideal for these areas because it can accept remote explosion proof or general purpose sensor inputs. Hydrogen sensors should be mounted near the ceiling.



Golf Cart Storage

Propane golf carts can emit carbon monoxide and the indoor areas where these are stored should have CO monitors in place. The Gas-Alert Max is a common choice due to the low cost and ease of use. A propane leak monitor should be considered in the tank storage area

If the carts are battery operated, consider hydrogen monitoring in the battery charging areas. The EC-Gold Dual is ideal for these areas because it can accept remote explosion proof or general purpose sensor inputs. Hydrogen sensors should be mounted near the ceiling.




Industrial Facility

The 4200-IG is specifically designed for industrial applications. The central robust panel can accept a wide variety of sensor and gas types.

It is important to consider the area classification (hazardous or general purpose) as well as the gas type. The gas densities will determine the sensor placement. Industrial locations may have both toxic and combustible concerns within the same working area.




Laboratories

Laboratories can have an unusual mix of both toxic and combustible gases.

Combustibles are typically from stored gases and chemicals such as methane, benzene, hexanes, etc. Toxic gases may be a result of these stored sources, in addition to the processes that involve chemical reactions or burning. Inert gases such as nitrogen are common in labs and may require oxygen depletion sensors rather than targeted sensors.

Review these applications with Arjay Engineering for the most suitable models.

Landfill Sites

Methane gas is a typical gas that is naturally generated in landfills. The methane may be used at site for cogeneration systems or exhausted to atmosphere. Monitoring for LEL levels of methane gas in normally clean air areas can done with our Hazardous Location Combustible transmitters.

Typical alarm setpoints are 10% and 20% of the LEL for Methane, which is 5% by volume. Methane is a lighter density than air and the sensors should be mounted high in buildings and scale areas where the gas can accumulate.


Loading Docks

Commercial and industrial facilities that have closed-in loading docks should consider monitoring for nitrogen dioxide from diesel exhaust and carbon monoxide from gasoline engines.

The GasAlert Max can monitor up to 20 sensors on one common loop for automatic fan exhaust control.


Oil & Gas

The oil and gas industry, both upstream and downstream, can have many gases of concern. Most applications will require explosion proof sensor transmitters.

The HLM 2000 sensors are available for combustible gases such as methane and for toxic gases such Hydrogen Sulphide.

Parking Garages

Ventilation control in parking garages is important for energy efficiency of fan use, heat and cooling loss, personal safety, and tenant comfort. Arjay specializes in monitors for HVAC control that can zone your garage to operate fans only when and where needed.

Carbon monoxide is the prime target but nitrogen dioxide and a propane sensing may be of interest as well.

Local building codes in your region may mandate gas detection in lieu of operating fans at high volumes 24 hours per day.

Our GasAlert Max is ideal for small garages or in large garages where discrete monitors in each zone is desirable. Our 4300-PG series provides a centralized scanning of all sensors and can map relays to control and interface with appropriate fans. If you have a Building Automation System, our EC-Gold sensor transmitters can link directly to your system with individual 4-20 mA signals or a Modbus interface.


Pharmaceutical

Manufacturing of pharmaceuticals can present many unique worker and plant safety concerns. Arjay offers many sensor technologies that can target these toxic and combustible hazards.

Review your specific needs with our sales experts for the ideal model and sensors for your application.
