What are the benefits of electrical submetering?

Energy management is a growing practice among companies that operate large buildings, campuses, and other complex facilities. Successful energy management requires detailed information on how energy is being used. However, this valuable information is not available in facilities being actively monitored. For effective energy management, facility engineers need to understand exactly how and where energy is being consumed on their properties.

Why Invest In Tenant Billing?

The goal of any commercial property owner is to attract tenants while also still being profitable. Operating a large building often means having a lot of expenses and other overhead costs, whether they be for maintenance, repairs, utilities, or the multitude of other expenditures any business could incur.

How NASA technology streamlined the calibration process

 Technicians at the Kennedy Space Center often work in cleanrooms, laboratories with high degrees of cleanliness provided by strict control of particles such as dust, lint, or human skin. These facilities must be contaminant-free environments where the air is repeatedly filtered and surfaces are smooth to prevent particles from getting lodged.

Why you need to calibrate pressure sensors in a cleanroom

There are many applications for differential pressure transducers, but none are more critical than those measuring the pressure parameters in a cleanroom. A cleanroom is a critical area used to manufacture medications, containers, enclosures, and other medical devices that require the products to remain sterile from manufacturing through delivery to the customer. The products manufactured in these environments are used to treat and care for the general population and are handled differently than other products.

Are Hospital Pharmacies Moving Toward Clean Room Standards?

The regulation language in U.S. Pharmacopeia Standard 797 (USP 797) has long been the guiding principle for cleanliness in hospital pharmacies that treat cancer patients with compounding sterile preparations (CSPs). For airflow in these special rooms, USP 797 outlines how spaces are to be pressurized, and what are permissible parts per million (PPM) particle counts.

How to Select a Power Meter

What Are You Monitoring?

One critical consideration when searching for a proper power meter is to determine what you're measuring. Is the monitored load signal-phase, split-phase or three-phase? What voltage/current ranges are going to be monitored? 

If you're interested in a power meter for residential or light commercial applications, then typically a single or split-phase meter would be the best cho

What is a Vivarium?

To most people, the term “vivarium” conjures up the image of a small fish tank-like glass box where a pet rat or gecko lives. While this is not incorrect, vivariums in biomedical research facilities are a bit more robust than what you might see in a high school science lab.

Vivarium Defined

Vivariums are enclosed areas designed to provide a stable environment for animals and plants for observation or scientific research. Often, vivariums contain a portion of an ecosystem for a particular species with controlled environmental conditions on a smaller scale. A vivarium you would find in an academic research setting contains multiple racks of various sizes depending on the species it contains.

What is peak demand?

Looking at your electric bill can be a daunting task. There are many factors that can affect your bill’s total — factors that are only amplified in large commercial and industrial sites.

One such consideration is peak demand. Peak demand is the largest instance of power usage in a given time frame, typically a rolling fifteen minute window. Measured in kilowatts (kW), peak demand is different than consumption. Total consumption  is measured in kilowatt hours (kWh) over a given period of time (e.g. monthly, quarterly, etc.).

What is power factor?

The power flowing through an alternating current (AC) load isn’t always pulling its full weight. Every AC circuit has some degree of non-working power as part of its total power reading and this can affect the amount of power a system is truly drawing.

How can Employees Contaminate a Clean Environment?

It is commonly known that gowning procedures and air flow requirements are essential to maintaining a sterile clean room environment. Workers and operators don’t realize how crucial employee training is and the enormous impact employees have with the sanitation of the cleanroom. Unfortunately, humans are considered to be the biggest threat to the cleanroom and the largest source for contaminants, accounting for 75% to 80% of particles and microbes generated in a room. Understanding how personnel create particles and microbes or bring in contaminants, can help structure proper employee training, greatly bringing down the risk for clean environment contamination.
