Controllers:
Controllers for temperature, humidity, pressure, etc. Typically used on equipment such as
- VAV boxes
- Heat pumps
- Fan coils
- Makeup air units
- Heating and Cooling coils
- Heaters
- Humidifiers
- Rooftop units
Controllers generally fall into two categories:
- stand-alone (do not communicate with others), and
- communicating through protocols such as BACnet
Product Categories:
Air Flow Measurement
Air Flow measuring devices for construction, field and laboratory use.
Control Actuators
Control actuators are used to open, close, and modulate air dampers and water valves.
Current Sensors and Switches
Current sensors and switches measure and control based upon current flowing through a conductor.
Fan Coil Controllers
Controllers for residential and light commercial fan coil units. Available as wall mounted only or as 2 piece packages: wall mounted thermostat and unit mounted controller.
Filter Pressure Monitors
Monitor the pressure changes in an HVAC system, triggering audible and visual alerts when the filters needs swapping out.
Flue gas analyzers
Combustion analyzers are instruments commonly used to measure the efficiency and proper operation of liquid, gaseous or solid fuel boilers (oil, natural gas, wood, biomass, etc.).
Gas Detectors
Gas detectors are used to sense and measure gases such as carbon monoxide and carbon dioxide.
Gas Leak Detectors
Measure combustible gas leaks such as methane, propane, isobutane, LPG as well as refrigerant leaks in HVAC systems.
Heat Pump Controllers
Heat pump thermostats/controllers for single and multiple stage heating & cooling units. Can be used from residential to commercial applications such as hotel rooms.
Humidity Controllers
Humidistats for controlling humidifiers and dehumidification equipment for a more comfortable living environment and manufacturing process.
Makeup Air Controllers
Controllers for makeup air units. Can be used for both large residential as well as commercial applications.
Pneumatic Transducers
Pneumatic transducers output a pressure proportional to the input signal. Typically used in pneumatic control systems.
Pressure Controllers
Static or differential pressure controllers, primarily used to control damper actuators for VAV systems or VFD equipped fans.
Pressure Manometers
A portable manometer is a pressure measurement device that can be easily carried and used to measure gas pressure, or the air flow and velocity of an air stream via a pitot tube.
Pressure Switches
Pressure switches for gases (usually for air) and liquids. Proving switches.
Pressure Transmitters - Gas
Pressure transmitters and transducers for gas media.
Pressure Transmitters - Liquid
Pressure transmitters and transducers for liquids.
Relays & Misc Controls
Relays are used to control higher amperage or voltage loads with a control signal. Also, lead lag controllers, wireless relays and more.
Rooftop Controllers
Used for control of single or dual stage heating/cooling equipment, such as rooftop and self-contained units. Can be used for both large residential as well as commercial applications.
Space Pressure Monitors
Room pressure monitors with alarming functions. Great for hospitals, labs, clean rooms and industrial environments.
Temperature Controllers
Thermostats for controlling 1 or more pieces of heating or cooling equipment.
Thermostats
Residential and light commercial thermostats for controlling heating and cooling equipment. Standard 24VAC and line voltage (115V) versions.
Thermometers and Hygrometers
Portable thermocouple and infrared thermometers are used to measure air and surface temperatures. Handheld thermo-hygrometers measure relative humidity, temperature and dew point.
VAV Controllers
Controllers used to control VAV boxes. Available in pressure dependent and pressure independent variations.
