Green Flow Series

Airflow | Temperature Measurement Solutions

The GF Series use the principal of thermal dispersion to determine the airflow rate. Thermal dispersion is ideal for HVAC applications that typically require measurement of low air velocities.

Green Alert Series

Remote Displays, Alarms and Network Bridges

The GA Series converts sensor signals to visual displays, notification alarms and/or provides a bridge between analog and network devices.

EMOAC Series

Minimum Outdoor Airflow Controller Modules for Systems with an Airside Economizer

The EMOAC controller modulate the control signal to a proportional analog outdoor/return air damper actuator to maintain the minimum ventilation rate required whenever the economizer controller (by others) is in minimum outdoor air mode.

OAC Series

Outdoor Airflow Controller for Systems without an Airside Economizer

OAC controllers are perfect for rooftop air handlers or air handlers with ducted outdoor air intakes when an airside economizer is not installed. Controllers are also ideal for ducted outdoor air intakes to fan coils, DOAS and makeup air systems.

Green Sense Series

Co2 Measurement and Control Solutions

GreenTrol CO2 sensors are available in wall and duct mount models, with some models having additional sensing capability.

Green Count Series

Occupancy Counters

The GC Series occupancy counters are designed for population-based demand control ventilation (DCV) so that only the outdoor air required for acceptable indoor air quality is provided.
