Hello, this is ELT Sensor.

Today, ELT Sensor, a specialized NDIR gas sensor company, will introduce you to the CO2 transmitter product for cold storage warehouses supplied by ELT Sensor to Maekawa Manufacturing, a Japanese company specializing in the production of freezers and cooling devices using the natural refrigerant CO2.

There are two types of cold storage warehouses: refrigerated storage warehouses for storing vegetables, fruits, etc., and frozen storage warehouses for storing frozen foods or freeze-dried foods.

 

These low-temperature storages usually use refrigerants, and Freon (CF2Cl2) and Ammonia (NH3) were commonly used, but the trend is currently changing to use CO2 refrigerant, a representative natural refrigerant, due to the effects of global warming.

Advantages of CO2 natural refrigerant

Reducing CO2 emissions (Lowering global warming index)

High stability (Non-flammable, non-toxic, natural refrigerant)

Energy saving effect

Disadvantages of C02 natural refrigerant

Risk of poisoning due to carbon dioxide leakage

Low-temperature CO2 sensor/transmitter to prevent carbon dioxide leakage.

(ELT CD-400BZ, ELT CD-400LBZ)

CD-400BZ is a product designed for use in low-temperature environments and is used to detect CO2 leaks when using CO2 refrigerant in facilities such as cold storages that go down to -40℃.

Product Features

NDIR (non-dispersive infrared) method

Users can directly set the upper and lower limits of C02 and temperature

Relay output function provided

BZ model works up to -40℃

[Among CO2 sensors applied to low-temperature storages, there are very few products that operate at -40℃, and the only product that has no malfunctions after more than a year of operation and operates with a relay at -40℃ is ELT SENSOR's "CD-400BZ" CO2 transmitter.]

Low-temperature CO2 sensor/transmitter for preventing carbon dioxide leaks

(ELT CD-100BZ, ELT CD-100LBZ)

CD-100BZ is a single-board type transmitter CO2 sensor designed for use in low-temperature environments. Like CD-400BZ, it is used to prevent CO2 leakage when using CO2 refrigerant in facilities such as low-temperature warehouses/freezers.

Product Features

NDIR (non-dispersive infrared) method

CO2 concentration measurement range selectable

(internal switch)

Carbon dioxide simple measuring device performance certification grade 1

BZ model up to -40℃

As this is a CO2 sensor that is absolutely necessary to prevent CO2 leakage when using CO2 refrigerant in the production of low-temperature storage facilities, please pay close attention to it, and if you have any questions about low-temperature storage CO2 sensors, please contact the ELT Sensor customer center and we will be happy to assist you at any time.
