2016 Super Kids 5K and Fun Run In honor of our client, UC Irvine, AGI is proud to sponsor the Super Kids 5K and Fun Run. This is an event sponsored by the University of California, Irvine/Children's Hospital of Orange County Pediatrics Residents and Miller Children's and Women's Hospital Long Beach to raise awareness about childhood obesity, and promote a day of fitness and wellness for people of all ages. AGI is happy to participate in a worthy cause for helping children achieve their goals.

Data Centres & Mission Critical Engineering Consulting & Design Project & Construction Management Low Humidity Cleanroom Design This article in ‘Building Services News’ magazine discusses some of the factors affecting the design of HVAC systems and equipment commonly used for dehumidification.

Designing HVAC systems to achieve low relative humidities within prescribed design and operating tolerances presents particular challenges for mechanical designers. Due to the problems that are often associated with low humidity or ‘dry’ rooms, proper design is required to ensure protection and adequate fluid supply to prevent excess water loss and adverse health effects to workers. Factors affecting cleanroom design and the manufacturing process are characterised as: airborne cleanliness – cleaner cleanrooms typically require higher airflow rates, temperature and humidity control zones and control methods, process exhaust – removing fume exhausts for any required abatement equipment and process equipment – process heat generating equipment and process cooling water system or the equipment’s fume exhaust.wii lens cleaning kit nintendo.com Before designing a low humidity room, the article explains the four most critical variables that need to be considered are the number of people working in the room, the specified temperature and humidity control level, the available space for room construction and the sensible internal heat load and/or process exhaust….where to buy air purifiers in singapore

FloVENT’s fast and easy-to-use menu system is designed specifically for engineers involved in the design and optimization of heating, ventilating and air conditioning (HVAC) systems.cd lens cleaner instructions “We found that applying FloVENT airflow modeling technology in the design of our clients’ clean rooms has proved beneficial for reduction of capital costs. As well, this has led to new design innovations such as new concepts for 300mm manufacturing environments.” “Without simulation, we would have had to use trial and error to adjust the HVAC design of the room after it had been built and occupied.

Instead, FloVENT results helped us make conclusions and optimize the final air distribution system design before construction. The model also helped us predict how the room could be used effectively with the existing HVAC air measurement and temperature controls.” FloVENT features the most complete and technically advanced model creation environment for HVAC airflow modeling design: Models that range in scale from diffusers, heat exchangers, grilles, CRAC units and enclosures are assembled quickly from a complete set of SmartParts (intelligent model creation macros). SmartParts capture modeling expertise streamlines model creation, minimizes solve times and maximizes solution accuracy. Robust Structured Cartesian Mesher Minimizes Solution Time FloVENT uses a structured-Cartesian grid method - the most stable and numerically efficient type available. The ability to localize is also included for finer resolution where it is needed, minimizing solution time and avoiding the penalty of grid cells that “bleed."

For over 25 years, the FloVENT solver has specifically addressed heating, ventilation and air conditioning (HVAC) applications: The solver, based on a Cartesian gridding system, delivers the most accurate results possible and the fastest solution time per grid cell. Massive disparity in geometric length scales are resolved using the unique ‘localized-grid’ technique which allows for integrally matched, nested, non-conformal grid interfaces between different parts of the solution domain. The conjugate nature of heat transfer is concurrently solved using a preconditioned conjugate residual solver together with a flexible cycle multi-grid solution technique. Pragmatic, unique and accurate solution termination criteria produce useful results in engineering, not academic, time scales. Fully rendered models, 3D flow animation and tools for dynamic manipulation of temperature and flow results, enable engineers to pinpoint thermal and ventilation issues and visualize design improvements quickly and effectively.

Texture mapping and video output enables powerful communication of design concepts with non-technical colleagues and customers. Cleanrooms aren’t defined as having zero pollutants in the air, but are instead classified according to how “clean” the air in the room must be in order for the room to be acceptable. United Maintenance, Inc. will design and install your room to meet or exceed whichever cleanroom classification your business requires. Federal Standard 209e and ISO Standard 1446 Cleanroom classifications define the size and number of particulates that are allowable per cubic foot of air. There are several standards or guidelines in place by which we test and monitor the interior environment to make sure the particulates in the air do not exceed a certain number. The older standard is U.S. Federal Standard 209e (or FS209e), which measures particles that are 0.5 microns or larger per cubic foot. However, newer guidelines have recently been introduced by the International Organization for Standardization (ISO 1446), which measures the number of particles per cubic meter.

Each standard helps us determine how clean the air is, and how clean the air needs to be. UMI builds all its cleanrooms to meet or exceed these standards. Maximum Particles / m³ U.S. Federal Standard 209E Cleanroom Classifications for Compounding Pharmacies (USP 797) Compounding pharmacies have their own special cleanroom requirements to meet, which are defined by Federal Standard 797 (or USP 797). UMI is able to meet and exceed these standards as well, building your room to specifications and monitoring the air to keep your pharmacy cleanroom in compliance with federal regulations. Current Good Manufacturing Practices (CGMP) UMI also stays aware of established federal guidelines on current good manufacturing and material handling practices (CGMPs), and stays well within these guidelines during the installation process of your cleanroom to ensure that the room does not become contaminated or compromised as a result of the installation itself. The actual materials used in your cleanroom are a key factor in maintaining its classification requirements.
