Building Pressurization

Use Ebtron airflow measurement devices to create a healthier building environment!

Measure and control outside air intake flow rates, especially during minimum outside air mode.

If the AHU provides air to a single pressure zone, control a return or relief fan to maintain the proper supply and return airflow rate differential. Control the supply fan to duct static pressure.

If the AHU provides air to multiple floors, consider treating each floor as a separate pressure zone to minimize stack effect. Provide airflow measurement onto and off of each floor and modulate a return air damper off of each floor to maintain the supply and return airflow rate differential. Control the supply and return/relief fans to duct static pressure.

If the AHU provides air to multiple pressure zones (such as labs or clean rooms), provide airflow measurement into and out of each zone to maintain the supply and return airflow rate differential. Control the supply and return/relief fans to duct static pressure.

Consider monitoring bleed flow or static pressure across critical boundaries and reset differentials as necessary.

When exhaust flow rates are variable or change significantly with wind and stack pressure, consider measuring exhaust flow rates if the changes are a significant component of the pressurization flow.

Chilled Beam Technology

Integrated comfort modules for heating, cooling and ventilation

Swegon offers a family of products consisting of comfort modules. The modules are designed to supplement one another and together create optimal room comfort.

The comfort modules operate on a basic principle that is closely akin to that of chilled beams. The difference is mainly that the comfort module distributes air in four directions instead of two. This maximizes the area where supply air is mixed with room air so that the modules discharge air at high capacity, yet they do not occupy more ceiling space than necessary.

The comfort modules are also optimized to quickly mix the discharged air with room air providing better comfort in the room. In heating applications, this technique can be advantageously utilized to efficiently provide provide heat along the ceiling.

Adjustable spread pattern

The easily adjustable nozzles in combination with Swegon ADC^II (Anti-Draught Control), offer maximal flexibility if changes in the room layout become necessary.

All the sides can be set independently of one another so that the comfort module can distribute more or less air and simultaneously discharge air in whatever direction desired in the room.

Modules:

• Supply air
• Supply air and cooling
• Supply air, cooling and heating (water)
• Supply air, cooling and electric heating

Z-Gard® C 485 Controller

For wide-ranging gas-monitoring needs, the economical Z-Gard C 485 Controllers are up to the task. The controllers connect with a wide array of MSA Z-Gard S Sensors, with controller models accepting up to 24 sensors. Relay outputs indicate warning, alarm or sensor fail for each zone, and units are available with one or two zones. A large LED readout displays the active channel and the corresponding sensor gas level.

Z-Gard® S Sensor

The Z-Gard S Sensor is designed to detect the presence of carbon monoxide, nitrogen dioxide and combustible gases in air. These sensors employ solid state, electrochemical or catalytic sensors which generate a representative output signal proportional to the calibrated operating range. All Z-Gard S Sensors are available with 2 output versions, a 4-20mA analog output, or an addressable RS-485 digital signal. Z Gard Sensors with RS-485 digital output are specifically designed to operate as a system with any Z-Gard CXII or C 485 Controller.
