Lochinvar: Lime Scale Accumulation: The Energy Thief

Water is used in a wide range of commercial applications. Every day, businesses and facilities heat water to serve the needs of their customers and patrons. While restaurants, laundromats, hotels, and car washes all require very large amounts of hot water to stay in business, nearly all companies rely on hot water in one way or another. Each year, a significant portion of their overhead is allotted to the fuel required to heat water, and everyday that allotment becomes slightly larger. However, many do not realize what they lose each year due to the negative by-products of heating water such as lime scale buildup, which cause efficiency losses, malfunctions, total equipment failure.

ECO-MAX™: Adsorption Chillers for Global Cooling

Adsorption chillers are a unique approach to achieving air conditioning and process cooling. Adsorption chillers are driven by hot water rather than from large amounts ofelectricity like conventional air conditioners. Capturing and using waste heat could be one of the largest conservation and green house gas reduction opportunities. Heat recovery is an opportunity to recycle energy that is typically wasted.

Electro Static Technology: Shaft Grounding - Fulfilling the Promise of Variable Frequency Drives

With the rising cost of energy, the use of variable frequency drives (VFDs) is growing at an increasing rate. By optimizing the frequency of a three-phase alternating-current (AC) induction motor's voltage supply, a VFD controls the motor's speed and torque while providing energy savings. And, these energy savings can be quite substantial - 20% or more - making VFDs a "green" solution as well as a wise money-saving investment.

Steam Accumulators and Steam Boiler Response to Load Changes

Steam load management is often neglected during the design phase of a steam delivery system. As a result, in the case of a boiler that serves steam-using equipment that cycles like an autoclave or sterilizer, steam quality and quantity at start up may suffer significantly. Understanding the significance of the events inside and outside the boiler pressure vessel during a rapid steam load demand period and choosing the correct design enhancements will reduce the consequences of rapid depressurization.

Maximizing Heating System Gains with Hybrid Boiler Plants

A hybrid boiler plant is defined as a hydronic heating plant combining condensing and noncondensing boilers. This system is designed to take advantage of the best properties of both boilers. Through the proper design and selection, 100% of the potential energy savings can be realized with a possible installed cost savings of one third to one half of the cost compared to an all condensing plant.

ECO-MAX Adsorption Chillers for Global Cooling

Adsorption chillers are driven by hot water rather than by large amounts of electricity like conventional air conditioners. This hot water may come from any number of industrial sources, including waste heat from industrial processes, prime heat from solar thermal installations or from the exhaust or water jacket heat of a piston engine or turbine. Organizations that could benefit from adsorption chillers include food and beverage processing; chemical, plastic, rubber, paper and cement manufacturing; hospitals; hotels; and school campuses.

Leveraging BIM for Energy Efficiency

It’s out there. The need to create more environmentally conscious, sustainable buildings isno longer a noble desire, but a dire necessity. Within this historical and industrial context, it hasnever been more important to precisely understand the progressive process of designing forsustainability and energy effi ciency.
