LED History and Construction

The LED (Light Emitting Diode) was first discovered almost a century ago. In the early 1960’s the first practical devices were developed in the US. These were red LEDs used for indicators and alphanumeric displays. Since then blue, green and violet light emitting LEDs have been developed and research has concentrated on achieving lower costs with higher light output and efficiency.

In order to create the white light needed for general lighting the LEDs are surrounded by phosphor materials that transform the monochromatic light from a blue or near-UV LED to broad-spectrum white light. The development and sale of LED substrates, phosphors and encapsulants are a key focus for MCHC.

LED bulbs and lighting fixtures combine the methods and materials described above, electrical circuits to drive the LEDs, an optical lens to extract and focus the light, and heat sinks to maintain the LED’s optimum operating temperature.

Retrofit light bulbs are now available to replace most incandescent and CFL bulbs. The efficiency of an LED bulb is approximately five times that of a standard incandescent bulb, so that even though the initial cost of an LED lamp is higher than the incandescent type the additional cost is more than recovered through the lower energy usage and much longer life of the LED bulb. LED lamps are also environmentally friendly because they lessen the need for power generation and do not contain hazardous materials such as mercury.

Lighting in homes and businesses typically accounts for about 20% of electrical energy use. Conversion of incandescent lighting to LED-based lighting can have a major impact on national energy usage and individual carbon footprints.

Air Curtains and Vestibules - ANSI/AMCA Standard 220


Air curtains can be considered as an alternative to vestibules in accordance with IECC-2015

ARLINGTON HEIGHTS, IL., October 30, 2013 – Air Movement and Control Association International, Inc. (AMCA International) announced today that the 2015 version of the International Energy Conservation Code will contain a provision enabling air curtains to be considered as an alternative to vestibules. For compliance, air curtains have to be tested in accordance with ANSI/AMCA Standard 220, and be installed in accordance with manufacturer’s instructions.

The International Energy Conservation Code is published by the International Code Council (www.iccsafe.org), “a member-focused association dedicated to developing model codes and standards used in the design, build and compliance process to construct safe, sustainable, affordable and resilient structures.”

Air curtains are devices installed above exterior door thresholds that blow a film (curtain) of air downward when the door is opened, trapping conditioned air inside the building.

“The IECC provision complements a similar provision adopted by the 2012 International Green Construction Code. Taken together, air curtains can help meet baseline energy codes and green construction codes,” said Brian Jones, Engineering Manager, Powered Aire, Inc., Greenville Penn., and chair of the AMCA Air Curtain Engineering Committee.

“AMCA International is proud of the AMCA Air Curtain Engineering Committee, Air Movement Code Action Review Committee, and Intercode Incorporated for their combined efforts to develop and support this successful code change proposal. We also want to thank the Colorado Chapter of ICC for working with us to develop the language, as well as the numerous code officials from around the country who supported and voted to approve the code change proposals,” said Wade Smith, PE, Executive Director, AMCA International.

Please review our Mars Air Doors - "Atmosphere is Everything"


Mars Air Systems has been manufacturing high quality air curtains for over 50 years. Our air curtains protect building environments from energy loss and windborne dust, dirt and fumes, along with flying insects. The air barrier created by the light stream of air over a doorway helps to improve inside sanitation and reduce operational energy costs.

Grieve Class A Ovens for Solvents/Vapors

Grieve Oven Corporation makes Class A Bench Ovens - Anderson-Bolds

CLASS A ovens are ovens for processing applications that involve solvents and vapors that are harmful to workers.

Grieve Model NBS Bench Oven(see below)

OSHA requires ovens processing flammable solvents or vapors to conform to the National Fire Protection Association Standard 86 (1999). NFPA 86 defines ovens for these applications as Class A ovens. In order to keep flammable vapor concentration at safe levels, Class A ovens include specific items of additional equipment to provide safety ventilation. This additional equipment is sized based on the volume of solvent being evaporated and the maximum operating temperature.
Safety ventilation also depends on the processing method. In batch processes, where all parts heat up at the same time, the flammable vapor concentration in not constant. As the work temperature rises the vapor concentration also rises to a peak value and then tapers off. This requires greater safety ventilation than in continuous processing where parts are heated sequentially and the vapor concentration remains constant.
Direct - fired gas ovens include Class A equipment to remove products of combustion. Combustion venting is sized at 183 standard cubic feet per minute of exhaust per 1,000,000 BTU/HR of burner rating. Depending on the amount of flammable solvent processed, a larger powered forced exhauster may be required to handle both combustion venting and safety ventilation.



Safety ventilation exhaust provides a supply of fresh air to ensure that the flammable vapor concentration in the oven remains below the Lower Flammable Limit (LFL) at all times. When more than one flammable solvent is present, safety ventilation is based on the solvent requiring the greatest amount of ventilation
Direct-fired gas heated ovens require combustion venting which must be added to the safety ventilation exhaust rate.
Combustible solids or substrates do not require safety ventilation unless flammable constituents are released when these materials are heated. Powder coating curing ovens require safety ventilation to be calculated as though 9 % of the powder weight is being evaporated as the flammable solvent Xylene.
Exhaust rates must be corrected for maximum operating temperature. As oven operating temperature increases, greater exhaust is required to compensate for the decrease in air density. Similarly, at altitudes over 1000 feet, the exhaust rate must be increased to compensate for lower air density.

 Batch Processing

For batch oven applications below 250° F, the safety ventilation exhaust rate must be sized at a rate of 440 standard cubic feet per minute for each gallon of solvent introduced into the oven in a batch. Between 250° F and 500° F, this exhaust rate must be increased by a multiplier of 1.4. Above 500° F, the 1.4 multiplier is not appropriate and a correction factor must be determined by tests run by the solvent manufacturer.
In addition, for solvents where the volume of air necessary to render 1 gallon of solvent barely explosive exceeds 2640 standard cubic feet, the exhaust rate must be increased. The increase is made by multiplying by a factor created by taking the volume of air necessary to render 1 gallon of solvent barley explosive and dividing it by 2640 standard cubic feet.
Safety ventilation and heat loss for a batch process can be estimated using the chart below. This chart shows the exhaust rate and heat loss for 0.1 gallon of solvent. The data is based on a solvent with LFL of 2640 standard cubic feet and on an installation located below 1000 feet in altitude.

 Continuous Processing

For continuous processing ovens, the safety ventilation exhaust rate must be sized to keep the concentration of solvent in the oven atmosphere below 25% of the Lower Flammable Limit (LFL) after the LFL has been corrected for operating temperature.
The specific gravity and vapor density of the solvent are used to determine the gallons of vapor created by 1 gallon of evaporated solvent. Combining this information with the Lower Flammable Limit determines the air volume rendered barely explosive when 1 gallon of solvent is evaporated. This is multiplied by a factor of 4 to limit the vapor concentration to 25% of the Lower Flammable Limit.

The safety ventilation exhaust rate is obtained by multiplying this volume by the number of gallons of solvent evaporated per minute.

Safety ventilation and heat loss for a continuous process can be estimated using the chart below. This chart shows the exhaust rate and heat loss for 0.1 gallon of Xylene. Xylene has specific gravity of 0.88 (Water = 1) and vapor density of 3.7 (Air = 1). The Lower Flammable Limit by volume is 0.9%. The amount of air rendered barely explosive per gallon evaporated is 2899 standard cubic feet. The calculated exhaust required per gallon of Xylene evaporated in continuous processing is 193 standard cubic feet per minute.
