Saving energy and improving the bottom line are critical for today’s automotive manufacturing facilities. Air Enterprises offers integrated turnkey, single-source solutions that deliver the best value available in an air handling unit with the lowest total cost to your facility. You’ll be able to: Air handling for automotive facilities With their all-aluminum low-leakage construction, air handling units from Air Enterprises provide the perfect solution to meet your facility’s maintenance and sustainability goals. stand up ac dc downloadOur high-quality air handlers deliver benefits such as:how big is a 3 ton ac unit Air replacement systems for paint booth, baking, and curing systemsac wall unit size Air Enterprises is an expert in the design and construction of air replacement systems with integrated heat recovery for industrial applications.

Air replacement systems replace contaminated air exhausted from industrial and commercial buildings or spray booths, with fresh, heated outdoor air, maintaining a constant leaving-air temperature regardless of the incoming, outdoor-air temperature. Air replacement systems replenish equal amounts of fresh air for each cubic foot of air exhausted. Recirculation air flow integration is provided with variable as required. Air Enterprises is an expert in the design and construction of industrial desiccant dryer systems and integrated air handlers with filtration for EPA Compliance where required. A desiccant HVAC system is an air-conditioning system that regulates water vapor (humidity) levels in the air using an adsorbent material (desiccant). These systems are drawing attention as humidification and dehumidification systems because they can control humidity and temperature independently, and can help conserve energy by utilizing waste heat. Low temperature desiccant dehumidification uses an adsorbent material that features the ability to adsorb and release (regenerate) water vapor at low temperatures.

We have extensive experience built implementing active and passive desiccant thermal wheels combined with our advanced air handling design and sophisticated filtration.  Potential applications include factories requiring humidity control, such as factories for lithium-ion batteries, semiconductors, and food, as well as cold and frozen-storage warehouses requiring defrosting measures. For more than 40 years, Air Enterprises has partnered with some of the most efficient automotive manufacturing plants in the world, including Honda, Mercedes, Ford and General Motors. to discuss air handling for your automotive plant.EXTREME TEMPERATURE AIR HANDLERBuilt to deliver precise control of environmental conditions.    ETC’s Custom Extreme Temperature Air Handler was introduced with the most extreme temperatures in mind. No matter the flow rate or temperature and humidity conditions required, the Custom Extreme Temperature Air Handler is built to deliver precise control of environmental conditions.  

Each Custom Extreme Temperature Air Handler is developed with consideration for our customers unique project requirements. If space is limited and performance is key, ETC will design a system that meets or exceeds your needs. Product Codes: CSF-61DX2 and OPT-658 The original Canterbury stopped-flow was based on a design described in a publication, Caldin, E. F., Crooks, J. E., Queen, A., J. Phys. E: Sci. Instrum. Vol 6, 1973, 930 - 932. This has proven itself to be an enduring design with many instruments sold over a thirty five year history. Indeed, the principle of maintaining the temperature control around the observation cell block and adjacent plumbing, avoiding complications with cooling drive syringes and valves is still apparent in today's design. These cryogenic instruments have been the instrument of choice among the inorganic mechanisms community as well as finding favour with the emerging field of bio-inorganic chemistry. With this development, it has become necessary to improve the performance of the instrument;

much of this has been as a result of developments with more conventional stopped-flow systems - computerised data acquisition and analysis, diode array (multi-wavelength) detection, and the introduction of more automated, user friendly operation. This latest generation of instruments bring together the capability of the KinetAsyst range of stopped-flow products with the low temperature sample handling technology specifically engineered for the study of fast reactions down to -90°C. The sample handling unit provides a means of sample delivery to the low temperature unit from air pressure driven syringes. Single mixing two syringe systems and four syringe double mixing systems are available. The stainless steel enclosure is designed to provide rigidity and resistance to chemical attack. It is important that the plumbing system provides for the total exclusion of air and moisture - in this respect, an option of stainless steel lines or stainless steel/PEEK/Teflon are available.

Typically the air driven instrument achieves 2 ms dead times Utilising the standard KinetAsyst systems high performance electronics and UV/VIS optical platform, it is supplied with a 75W Xenon lamp. The system can operate in single wavelength mode with a photomultiplier or photodiode array mode for the collection of whole UV/VIS spectra (300 - 700 nm). In diode array mode, spectra can be acquired at (typ) 3 ms intervals. The sample cell has a standard 10 mm path length with 1.5 mm available as an option with connection via light guides. The low temperature, Cryo Unit, whose flow lines and mixing chamber are immersed in a thermostating medium, facilitates the control and regulation of temperature using liquid nitrogen fed from a Dewar as a heat sink and a proportional controller with electrical heating to maintain a set point down to -90°C. Additionally, a dip coil (optional) can be included, which can be connected to an external circulator to maintain more moderate temperatures.

The sample delivery or sample handling unit is not thermostated. The instrument is controlled along with data acquisition from the Kinetic Studio software; this is a feature rich application developed specifically for the operation of the stopped-flow systems running on the Windows XP, Vista and Windows 7 platforms. This provides the user with a user friendly and effective facility for the acquisition, processing and analysis of high quality kinetic data. Saouma, C.T., Kaminsky, W., and Mayer, J.M.
