ANTEC Controls by Price: Introducing Venturi Valves

Venturi Valves are mechanically pressure independent airflow control valves designed specifically for room pressure and fume hood control applications.

Available in constant or variable air volume configurations, the Venturi Valve is able to control flow without the need for airflow measuring devices in the airstream. The device eliminates the possibility of lint or other airborne particulates interfering with the control or accuracy of the valve. The valve provides electronic flow feedback using a precision potentiometer to output a signal proportional to airflow.

Each valve is factory characterized on NVLAP accredited airflow calibration stations (NVLAP Lab Code 201067-0 complying with ISO/IEC 17025:2005) using N.I.S.T traceable equipment to ensure dependable and repeatable valve accuracy. Antec Controls Venturi Valves are accurate to ±5% of flow when operated within the designed pressure range. Valve accuracy is unaffected by inlet conditions and does not require any minimum distance of straight duct on the inlet or outlet of the valve.

Mechanical pressure independence is achieved through the highly engineered internal plunger assembly. The plunger assembly ensures the valve responds instantaneously to changes in duct static pressure. Turndown ratios reaching up to 20:1 maximize energy savings when space unoccupied or when at minimum flow set point.

FEATURES

• Electronic airflow feedback prevents dust/ lint contamination from deteriorating airflow reading
• Characterized and calibrated using NVLAP accredited airflow stations
• Medium or low pressure operation
• Operating pressure feedback

Pace™ is a flexible controller for room containment through pressurization. Pace™ delivers seamless environmental monitoring, control and energy savings in critical spaces.

To achieve room pressurization requirements, Pace™ allows for either Volumetric Flow Offset or Pressure Control strategies. Pace™ achieves airflow control utilizing Venturi Valves, Venturi FX valves or Terminal Units.

Aermec provides efficient and innovative HVAC solutions, including air to water chillers and heat pumps, water to water chillers and heat pumps, free cooling chillers, modular free cooling chillers, dry coolers, condensers and the world’s quietest fan coils.

The NRB Series: A One Stop Shop for Engineers and Contractors

• The NRB may be the only chiller line available which offers from 50 through 240 tons as a chiller, heat pump, integrated free cooling chiller, desuperheater, heat recovery all in one model or range.
• The unit is AHRI certified and meets the AHRI standard even with the integrated free cooling version. 
• The NRB is one of the quietest chillers / heat pumps on the market as all compressors are isolated and located inside an insulated compartment as a standard feature allowing for sound ratings as low as 71 dB.
• A Night Mode is also available which will lower the fan speeds automatically as the temperature drops if desired while maintaining the set point.
• The NRB is available with no hydronic kit if desired but it is also available with internal buffer tank, pumps (high or low pressure) redundant pumps, expansion tanks and more.
• The NRB when designed with the hydronic kit is truly a plug and play machine.
• The units are available with high static fans (up to 1.4” wc) which allow them to be placed indoors or in a parking garage if necessary and be ducted to the outside. 
• The NRB Series is an excellent value, offering many integrated features.
