2010 Go Beyond Awards

Beyond Laboratories
Beyond Green

Tek-Air Systems Inc., Danbury Ct, received a national award from The International Institute for Sustainable Laboratories (I2SL) and Labs For The 21st Century, sponsored by the U. S. Environmental Protection Agency and the U. S. Department of Energy at their conference last month in Albuquerque, New Mexico. Tek-Air received the honor for “manufacturer of the year”. The award was given to Tek-Air Systems Inc. as a manufacturer that significantly contributes to reducing the overall environmental footprint and energy usage of a laboratory, hospital or critical facility through innovative design and engineering of equipment. Tek-Air Systems Inc. manufactures air flow control valves, indoor and outdoor air flow measuring devices, laboratory controllers, fume hood controllers, monitors, and room pressure monitors. Established in 1983, Tek-Air defines, develops and delivers innovative environmental airflow control products and comprehensive solutions for critical and non critical facility environments, focusing on safety, energy savings and sustainable design.

Tek-Air, a regular vendor in the Labs21 Technology and Services Fair and sponsor of the Labs21 Annual Conference, approaches the market with a strategy that employs many Labs21 principles. When making presentations and training users on equipment, Tek-Air utilizes the Labs21 Low-Energy Design checklist to emphasize total building energy savings potential. Tek-Air's onsite teaching laboratory offers a personal, tactile way to promote the Labs21 principles. All ductwork and other installed devices are below the ceiling to offer a unique learning experience. The teaching lab is versatile and can be set up to accommodate an individual group's needs.

Beyond promoting Labs21, Tek-Air uses local vendors for product components when possible, and all its electronics are developed based on the latest standards and codes as they relate to environmental impacts. Tek-Air's Pneumavalve and Accuvalve operate at low static pressures, offering users significant energy savings. Tek-Air also promotes the use of technology and system designs that consume less energy.

Tek-Air Room Temp Sensor

Tek-Air Systems now offers a room temperature sensor that has:

Large Easy-to-Read Display, Membrane Pushbuttons for Wipedown Cleaning, Room Temperature Adjustment, Occupancy Button and Status, and Optional Humidity Sensing, Two Year Warranty

The VT800 Fan Inlet Probe for Small Fans

Tek-Air Systems now has a VorTek Fan inlet probe that is designed to bring VorTek airflow sensing to small fan inlets and has little affect on fan performance as other designs do. It's small profile and simple mounting makes installation easy in very tight fan housings.

The Protocessor by Field Server

Tek-Air Systems has worked with FieldServer to develop a bridge for the information from the SmartLab and Fume Hood Controller System over to BACNet I/P, BACNet MSTP, LON, Modbus and N2. These devices are easily configured to be virtual controllers to the Building Management System, by using an export feature supplied with the SmartLab Configuration Software.

The AccuValve™ by Accutrol, LLC - AHR 2008 Innovation Award Winner

Tek-Air Systems Inc. AccuValve™ by Accutrol, LLC is an electrically operated airflow control valve for critical environments such as laboratories and clean rooms. The valve, created for sustainable “green” design, offers very low pressure drop for energy reduction and savings along with safety by utilizing true airflow measurement.

The Tek-Air AccuValve™ AV2000 airflow control valve is a revolutionary product in which Computational Fluid Dynamics (CFD) was utilized to aid in its design. This resulted in a valve that maximizes turndown while maintaining high accuracy throughout the flow range. The AV2000 is the first truly new design in airflow control valves in decades.

Accutrol’s new airflow control valve incorporates high accuracy airflow sensing with a revolutionary but simple design. The AV2000 is designed for use in applications where turndowns of up to 8 to 1 are required while maintaining accuracies of 5% of reading over that flow range, ensuring precise airflow control. R&D laboratories, process pharmaceutical manufacturing and vivariums are just a few applications for the Tek-Air AccuValve™.

The AV2000 divides the airflow into two equal chambers with an airfoil shaped compression section. When the air is divided into the chambers it accelerates and compresses becoming laminar. The laminar airflow improves the accuracy of the airflow sensor enabling better turndown as well. Much like a silencer this also results in a valve that is very quiet.

The Tek-Air AccuValve™ also incorporates high accuracy Vortex shedding airflow sensors in each chamber. The sensors are located to give a high degree of accuracy throughout the flow range. The higher velocities in the chamber also allow for greater turndowns than is possible in a conventional valve.

The unique design of the Tek-Air AccuValve™ provides true flow feedback while avoiding the drawbacks of other valve designs. This feature provides the end user the benefit of the highest degree of safety in knowing that the critical space is accurately monitored and controlled.

The AV2000 incorporates a compression section with a streamline design with a static regain section on the downstream side. This design provides a low pressure drop requiring less fan horsepower and better noise performance.

There are no straight duct runs required before or after the valve making application of the valve very simple. The air compression in the valve provides laminar airflow throughout the airflow range providing repeatable airflow measurement regardless of the inlet or outlet conditions. The design also provides large turndown capability, thereby allowing a large range of applications. All parts are accessible from the front of the valve simplifying installation requirements.

The Tek-Air AccuValve™ is designed to provide many years of maintenance free operation. Unlike the other airflow valves which have many critical parts, such as springs, cones and linkages in the air stream, the Tek-Air AccuValve™ was designed with few moving parts which are out of the air stream, increasing the overall reliability and lifetime of the valve.

The APEX Family of Fumehood Monitors

Tek-Air is proud to introduce the APEX Premier™ High Performance Fume Hood Monitor and the APEX Basic High Performance Velocity Alarm to the Critical Environments Industry. The APEX Premier™ utilizes state of the art technology to provide the highest level of performance achievable in a fume hood monitor, while the APEX Basic was developed by Tek-Air to provide the industry with a cost-effective, accurate and reliable velocity alarm to help ensure a safe operating environment for laboratory personnel. The APEX Basic is suited for use on all types of fume hoods and Biological Safety Cabinets.
