Explore our flagship smart environmental sensors and carbon monoxide controllers engineered for optimal HVAC automation, industrial safety compliance, and energy savings.
As the energy capital of the world and one of the fastest-growing commercial hubs in the United States, Houston, Texas presents a unique and demanding environment for indoor air quality (IAQ) and hazardous gas management. From the expansive industrial complexes along the Houston Ship Channel to the soaring commercial office towers in Downtown Houston and the massive medical facilities of the Texas Medical Center, ensuring atmospheric safety is a paramount operational requirement.
Carbon monoxide (CO) is a colorless, odorless, and highly toxic gas generated by incomplete combustion. In Houston's dense urban and industrial ecosystems, potential CO hazards frequently arise from underground parking structures, commercial boiler rooms, logistics centers with propane-powered forklifts, and heavy manufacturing facilities. Deploying reliable, high-precision Carbon Monoxide Controllers is not only essential for protecting human life, but it is also critical for compliance with local municipal codes, OSHA industrial safety standards, and international green building benchmarks such as ASHRAE and LEED.
Full adherence to OSHA, ASHRAE 62.1/62.2, and Texas building safety codes for enclosed parking and commercial facilities.
Proprietary calibration algorithms deliver exceptional long-term stability, minimal drift, and reliable real-time CO alarm triggering.
Seamless connectivity with Building Management Systems via Modbus RS485, BACnet, or standard 0-10V/4-20mA analog relay outputs.
Help you build and maintain a healthy indoor environment
Our work makes a difference in helping you make the healthy indoor air quality. As one of the earliest companies in China engaged in air quality monitoring products, Tongdy has been always focusing on its strong technology development and design capabilities on the indoor air quality monitors.
Focus on air quality detection and control over 15 years
Our Purpose: We foster research and development on obtaining accurate air quality data, help you well understand and improve the air you breathe by quantitative assessment and data analysis.
For pursuing our ultimate purpose of creating healthy indoor air quality, we’re committed to obtain real and accurate data and cultivating the next generation of innovators in technology and engineering.
As energy efficiency mandates tighten across Harris County and Texas, intelligent Demand-Controlled Ventilation (DCV) utilizing advanced Carbon Monoxide controllers is replacing traditional continuous exhaust fan operation.
Houston features thousands of multi-level commercial and residential parking garages. Running high-powered exhaust fans continuously consumes enormous electrical energy. Tongdy CO Controllers continuously sense carbon monoxide buildup, automatically triggering exhaust fans only when gas concentrations approach predefined safety thresholds (e.g., 25-35 ppm), reducing HVAC energy consumption by up to 60%.
In the industrial corridors of Pasadena, Deer Park, and Baytown, enclosed equipment maintenance bays, loading docks, and warehouse facilities experience heavy internal combustion engine traffic. Dual-gas and dedicated CO controllers ensure toxic fumes are detected early, protecting workers from acute carbon monoxide poisoning and meeting strict OSHA workplace compliance.
Facilities inside the Texas Medical Center and Galleria office towers utilize integrated gas sensors connected directly into centralized Building Automation Systems (BAS). Real-time telemetry allows facility engineers to monitor air quality levels across multi-zone ductwork, ensuring occupants breathe clean air while earning green building credits.
Historically, basic electrochemical carbon monoxide detectors served strictly as emergency alarm devices. Modern smart building engineering, however, demands intelligent controllers capable of proportional analog control (0-10V, 4-20mA), digital communication (Modbus RTU/TCP, BACnet MS/TP), and multi-parameter sensing. Tongdy’s research focuses on integrating real-time carbon monoxide sensing with temperature, relative humidity, carbon dioxide (CO2), and total volatile organic compounds (TVOCs).
By implementing proprietary auto-calibration algorithms and high-durability sensor modules, Tongdy Carbon Monoxide Controllers eliminate false alarms caused by cross-sensitivity to humidity spikes or ambient temperature fluctuations—a vital feature given Houston's notoriously hot and humid subtropical climate.
Tongdy actively develops air quality monitors and is devoted in healthy indoor air quality, and strive to become an excellent enterprise model. As a corporate citizen, Tongdy has contributed to public welfare undertakings such as cooperate with public benefit corporation, like WELL—the world’s leading organization focused on deploying people first places to advance a global culture of health, especially exploring the impact of indoor air quality to people’s health based on The WELL Building Standard™.
