AMMONIA LEAK DETECTORS
*NEW* MODEL LBW-WATCHMAN
The LBW-WATCHMAN Ammonia Leak Detector from Cool Air Incorporated has all the features you need to protect your personnel and product. It has a semi-conductor, long-life ammonia sensor cell that provides fast and accurate detection of ammonia gas. The sensor cell will not deplete during an ammonia leak, from background ammonia vapors, or during testing and/or calibration.
The front panel display indicates ammonia concentration in parts per million (PPM). The detector has a 4-20 mA analog output for PPM that will seamlessly integrate with your existing automation system. To reduce nuisance alarms during cleaning, servicing, testing, and/or calibration, the LBW-WATCHMAN has a service mode that temporarily disables the detector’s 4-20 mA signal.
To further enhance the value of this detector, Cool Air Incorporated offers these beneficial options: ABS washdown/utility tube, external service switch, LCD door monitor. The LBW-WATCHMAN detector is housed in a custom-made safety yellow, NEMA 4X, UL-listed, CSA, IEC, IP66 enclosure with viewing window. The LBW-WATCHMAN is fully compatible with the Cool Air Inc. Digital Central Supervisory Alarm Panel.
The LBW-WATCHMAN is manufactured in the USA and comes with our standard 36-month limited warranty.
*NEXT GENERATION* MODEL LBW-420
The next generation model LBW-420 ammonia leak detector is easy to use and requires little maintenance. This versatile detector has all the features you need to get the job done safely and is certified by TUV Rheinland.
It comes equipped with a built-in ammonia sensor that accurately monitors ammonia concentration in parts per million (ppm) and displays it on the detector with a reading between 0 to 1000 ppm. There are now two indicator lights: one for Low Alarm and one for High Alarm.
The detector also has a convenient "service mode," which will temporarily disable the detector's alarm relays and the 4-20 mA signal during testing, calibration, or routine maintenance.
The following enhancements have been made to the next generation LBW-420:
- Cleaner simple look, fewer LEDs.
- Remove the "P" indicating PPM.
- NO need to enter sensor group number.
- Selectable display start point 0PPM or 25PPM (factory default is 25PPM).
- Selectable Service Mode timeout 15, 30, 45 or 60 minutes (factory default is 15 minutes).
- Auxilary relay is for detector errors only, or it can be programmed to activate with the Low Alarm or High Alarm relays as well (factory default is errors only, no relay pairing).
The model LBW-50 ammonia leak detector has been the 'workhorse' model for Cool Air Incorporated. The electronics are housed in a NEMA 4X enclosure and the detector shares some of the same features as the LBW-420. Some of those features include, progressive indicator lights for ammonia concentration, relay outputs for early warning and alarm, and a service mode. This product is pending certification from TUV Rheinland.
The LBW-50 can be adjusted to set off its early warning (factory set, non-field adjustable) and alarm (field adjustable) relays for an ammonia concentration value of between 25 and 800 ppm. This product does not have a display screen or output a 4-20 mA signal like the LBW-420 leak detector model.
AMMONIA RELIEF LINE VENT GAS DETECTOR (MODEL LBW-RLV)
The model LBW-RLV leak detector is specially designed to monitor the ammonia gas concentration in a relief line vent pipe. After many years of reliable service as the 'LBW-50-RLV', Cool Air Incorporated has re-designed this unit to allow for more internal space for wiring and/or installing our optional back-up battery. Also, this unit has a service mode that allows for testing or calibrating without setting off any external alarms.
The solid-state ammonia sensor for this product is located on the back of the unit. The 2-inch, schedule 80 PVC fitting that the sensor socket is potted into, should be installed using a union. This will facilitate removing the unit for testing, calibrating, or servicing. The detector early warning (factory set, non-field adjustable) and alarm (field adjustable) setpoints can be set for an ammonia concentration value of between 25 and 800 ppm. It has indicator lights for both power and service mode, and a progressive light tree for the ammonia concentration.
HANDHELD AMMONIA LEAK DETECTOR (MODEL LBW-HHS)
The Cool Air Incorporated handheld ammonia leak detector is a versatile tool for performing routine checks in engine rooms, around evaporator coils in processing areas, coolers, or freezers, or in confined areas prior to entry. This unit is designed for easy one-hand operation, contains an internal sampling pump for drawing in the target gas, and uses a flexible wand for pinpointing the source of a leak. The large LCD display allows for the measured values to be easily displayed and, for low-light environments, a back-light insures readability.
The ammonia sensor for this detector is a 'smart sensor'. This type of sensor has all of the logic built into it. So, when calibration is required, only the sensor needs to be calibrated not the entire unit.
DIGITAL CENTRAL SUPERVISORY ALARM PANEL (DCSAP)
The Digital Central Supervisory Alarm Panel is excellent for monitoring several leak detectors at once. This panel comes in four different configurations to monitor either 8, 16, 24, or 32 independent zones.
The DCSAP has an easy to read, large LED display screen that shows the ppm reading, as well as, the zone or detector it is linked to. Each detector number on the panel has its own early warning and alarm indicator lights, unit label, and a switch that will put that detector into either normal mode or silent mode (during alarms).
In addition to having visual lights for early warning and alarms, the panel also includes a single audible alarm, that will go off if any detector is alarming. The horn can be silenced with either the alarming zone or global switch. Once the ammonia concentration decreases below the alarm setpoints, the horn will sound again until the alarming zone or global switch are put back into the normal mode.
