What are Greystone Products?

The HVAC sensors & controls manufactured by Greystone Energy Systems are the world’s finest, a premier manufacturer of Greystone HVAC sensors & controls for over 40 years. Greystone Energy Systems is a manufacturer of high-quality sensing devices used to measure everything from the air we breathe to the pressure in the ventilation ducts of skyscrapers.
Greystone’s products are the “eyes & ears” of a building’s brain (the Building Automation System). Without accurate sensors, a building cannot effectively autoregulate temperature, humidity, or fresh air, resulting in energy waste and discomfort for its occupants.
Key Greystone Product Categories

Greystone offers many different categories of products in its extensive catalogue; they can all be broadly categorized as follows –
1. Temperature Sensors – Measure ambient air temperature, ducted air temperature, and liquid temperature.
2. Humidity Transmitters – Measure moisture levels that are suitable for human beings and sensitive equipment.
3. Pressure Transducers – Monitor the flow and pressure of air and liquids.
4. Air Quality Sensors – Detect CO2, VOCs(Volatile Organic Compounds) and (Particulate Matter)(PM 2.5).
5. Gas Detectors – Safety devices for the detection of carbon monoxide (CO) and nitrogen dioxide (NO) within parking garages or mechanical rooms.
Why Sensors Matter in Modern Buildings
It is crucial to comprehend why these gadgets are the basis of Smart Buildings.
1. Energy Efficiency – Buildings consume roughly 40% of the worldwide energy. Precise sensors control HVAC systems from over-cooling or over-heating, directly decreasing utility expenses.
2. Occupant Health – Complete supervision of CO2 and Particulate Matter (PM2.5) controls Sick Building Syndrome, resulting in higher productivity and lower absenteeism.
3. Equipment Longevity – When sensors precisely report system pressure, pumps, and fans run within their desired parameters, decreasing wear and tear.
Temperature Sensing – The Foundation of Comfort

Temperature control is the most commonly approached feature in any HVAC system. Greystone delivers a huge range of Greystone HVAC sensors and controls, particularly for temperature measurement.
1. Duct Temperature Sensors
These are developed to supervise the air temperature within the ventilation shafts. They come in rigid probe versions for standard ducts and averaging versions for big air management units.
- Averaging Sensors – These use a long, adaptable probe that zig-zags in the duct to deliver a mean temperature, controlling hot spots or cold spots from providing false readings to the controller.
2. Immersion Sensors
For systems that utilize chilled or hot water, immersion sensors are utilized. These are incorporated into thermowells inside pipes to measure fluid temperature without leaking.
3. Space/Room Sensors
Available in sleek, minimalist designs, these are the only components of the HVAC system most office employees ever see. They usually include features such as –
- Overrise Buttons – Permits users to wake up the HVAC system after hours.
- Setpoints Adjustments – Local control over the temperature.
- Communication Jacks – For specialists to plug in and diagnose the system.
Humidity & Dewpoint Transmitters
Handling moisture is a delicate science. Too much humidity results in mold and structural decay; very little results in respiratory irritation and static electricity that can fry electronics in data centers.
Greystone’s humidity line uses extremely stable thermoset polymer-based capacitive sensors. These are resistant to chemical contaminants and deliver accuracies of ±2%, ±3%, or ±5%, based on the application. Several of these units also deliver calculated Dewpoint values, which are crucial for controlling condensation on chilled beams and pipes.
Air Quality and Gas Detection
As indoor air quality moves to the forefront of building norms such as LEED and WELL, Greystone has invented a multi-parameter sensor.
1. CO2 Sensors
By utilizing Non-Dispersive Infrared technology, Greystone CO2 sensors permit demand-controlled ventilation.
- How DCV Works – Rather than operating the fresh air fans at 100% capacity all day, the sensor detects when CO2 levels rise and tells the system to bring in fresh air only when required. This can save up to 30% in heating/cooling expenses.
2. Particulate Matter (PM2.5) and VOCs
Greystone’s IAQ series supervises invisible threats –
- VOCs (Volatile Organic Compounds) – Find smells, cleaning chemicals, and outgassing from furniture.
- PM2.5 / PM10 – Supervises dust, smoke, and pollen, making sure the building’s filtration system is working effectively.
3. Toxic Gas Detectors
For parking garages and mechanical rooms, Greystone delivers Carbon Monoxide and Nitrogen Dioxide (NO2) detectors. These are safety-critical gadgets that trigger exhaust fans or alarms to control gas poisoning.
Pressure and Flow Monitoring
Pressure measurement is the key to handling air distribution.
1. Dry Pressure Transducers – These measure the differential pressure between two points. This is utilized to supervise if a filter is dirty or if a fan is actually moving air.
2. Liquid Pressure – Utilized in boiler and chiller systems to make sure the pumps are sustaining the right pressure to move water to the top floors of a high-rise.
3. Air Velocity Sensors – These measure how quickly the air is moving in meters per second (m/s) or feet per minute (f pm), which is crucial for balancing airflow in complicated laboratory or hospital environments.
Role of Airmep Sales Corporation in India
In the Indian market, sourcing top-notch automation elements can be difficult because of considerations about lead times and technical support. Airmep Sales Corporation has built itself as a leading authorized channel partner for Greystone.
Why Buy Through Airmep?
1. Genuine Products – Airmep guarantees 100% authentic Greystone hardware, securing your project from counterfeit elements that could fail prematurely.
2. Expert Consultation – Their engineers do not only sell a box. They assist contractors in choosing the appropriate sensor for the particular environment, whether it is a high-humidity coastal region or a sterile pharmaceutical cleanroom.
3. Post-Sales Support – Building systems is complicated. Having a local partner such as Airmep makes sure that if a sensor requires calibration or troubleshooting, assistance is just a call away.
4. Inventory Management – By sustaining a stock of typical Greystone HVAC sensors and controls, Airmep assists in decreasing project downtime and meeting tight construction deadlines.
Application Across Different Sectors
1. Healthcare & Life Sciences
In hospitals, Greystone pressure sensors sustain Pressure Envelops. For example, an isolation room should be kept at a lower pressure than the hallway to make sure no germs escape when the door opens. Greystone’s ultra-low pressure sensors can find modifications as tiny as 0.1 inches of water column.
2. Data Centers
Data centers are sensitive to both heat and static. Greystone’s high-accuracy humidity and temperature transmitters make sure that the environment remains within the stringent ASHRAE policies for IT tools, controlling expensive server failures.
3. Commercial Offices & Retail
In shopping malls and offices, the focus is on total IAQ. By merging CO2, VOC, and temperature sensing, Greystone products make sure a pleasant environment that keeps clients in stores longer and employees more concentrated.
Conclusion
Greystone Products provides the accuracy and durability needed for the job, whether you’re trying to lower the energy bill of an old warehouse or obtain a LEED certification for a new skyscraper.
