There are a variety of industries that regularly use the lab/bench ovens, including aerospace, medical, solar, metal-finishing, pharmaceutical, and education.

Lab/bench ovens are usually used in the industrial setting when small batches of product are needed or the size of the workspace is limited. These ovens are often positioned on a table or bench but can also be floor-mounted depending on the setting. Lab/bench ovens often use trays to simplify the heating process.

Industrial Clean Room Ovens

Posted on April 21, 2022 by jpwdesign

Clean room ovens create a sterile environment for hygienic and sterile process applications in manufacturing. The pharmaceutical and medical industries take the lead in the need and request for these types of ovens. Clean room ovens, also known as dry-heat sterilizing ovens, are used to cure, dry, sterilize and depryrogenate.

Recently, JPW customized a clean room oven for a pharmaceutical pill manufacturer. They requested a dry-heat sterilizer for their specific project.

“Clean room ovens have different classifications,” states Mike Jameson with JPW Industrial Ovens and Furnaces. “The type we typically produce are Class 100 clean room environment ovens for processes where eliminating particle contamination is required. We also see more requests for these types of ovens than we have in the past.”

Clean Room Oven Standard Features

JPW offers various size, cycle, and temperature option requirements to meet your clean room industrial oven needs. Our clean room ovens are available in multiple configurations, including lab, bench, walk-in, cabinet, and continuous process. JPW’s clean room ovens can be customized for your specific needs and will meet or exceed Class 100 air standards. Standard features of our clean room ovens include:

Construction: corrosion-resistant stainless-steel interior and exterior, fully sealed interior and exterior, adjustable shelves
Filtration: two heat-resistant HEPA filters
Temperature: up to 500°F with uniform heating
Door: fully-sealed adjustable door hinge with lever-actuated door latch and silicone gasket
Controls: user-friendly, control panel with large LED display or PLC
Air Flow Patterns: vertical or horizontal

Customized Clean Room Ovens vs. Standard Clean Room Ovens

While JPW can customize your clean room oven, we also offer a standard line of stock ovens that may meet your industrial needs.

“The turnaround time for a standard oven we have in stock with modified customization is about 4-6 months, while a completely custom-built clean room oven can take six months or more,” adds Jameson. “Prices for a small clean room oven range from $125-150,000.”

If you need a clean room industrial oven, don’t hesitate to contact JPW. Let us help you determine what solution is right for you. Whether you need a model from our stock line or a customized oven, JPW can meet your needs.

What Are Continuous Process (Conveyor) Ovens?

Posted on April 7, 2022 by jpwdesign

Continuous Process Ovens (or Conveyor Ovens) are batch ovens that repetitively operate with a specific product traveling through them. It can easily be compared to an automated assembly line. The conveyor belt moving through the oven has a job to do and keeps on doing that job until the product is complete. This type of oven can produce a high volume, uniform product due to a consistent, regulated temperature as it passes through each chamber or zone.

Mike Jameson with JPW Industrial Ovens & Furnaces indicates that almost every continuous process oven that goes out our door needs some customization and is project-based driven.

Since customization tends to be the standard, when one is needed, JPW recommends planning ahead.

“In the conveyor oven world, these ovens are project, product and process-specific,” Jameson adds. “These ovens are used to do one particular job whether it is curing or drying, for example, and that is it. A typical life cycle of a product used in a continuous process oven is about five years, some ten. So when considering the purchase, I always ask what the desired outcome of the oven is, what material will be treated, and how will the oven fit in the project’s manufacturing process.”

After these initial questions are answered, Jameson says the oven design, temperature requirements, and type of belt material can be easily identified.

Types of Applications and Ovens

These types of ovens can be used for various applications, including tempering, annealing, curing, pre-heating, drying, heat-shrinking, and heat-forming. They are also used in the aerospace, defense, fiber optics, wood and metal finishing, plastics, rubber, industrial processing, pharmaceutical, electronics, printing, and automotive industries.

Types of continuous ovens include:

Flat conveyor belt
Chain conveyor
Ferris wheel
Carousel
Overhead trolley
Serpentine
Chain-on-edge
Spindle
Slat type
Strip cure
Print plate
Pusher ovens
Dog beams
Wash-draw furnaces
Multi-tier

With over 100 years of combined experience serving industrial markets with innovative oven products, design solutions, and competitive services, when planning the purchase of a continuous process or conveyor oven, let JPW help. We are skilled at finding solutions and crafting each oven to suit your unique needs while keeping you competitive in the marketplace.

Gerry Retires

Posted on August 16, 2021 by jpwdesign

Gerald “Gerry” Mitcheltree recently retired from JPW Industrial Ovens and Furnaces after working with the company for 14 years as a fabrication supervisor. On his last day, Friday, August 6^th, his fellow co-workers and supervisors organized a much-deserved send-off.

When asked what he will miss most about JPW, he joked, “I will miss arguing with Briana and Chelsea the most.” Gerry quickly added that JPW has a good atmosphere and great people.

A lifelong Williamsport resident, Gerry and his wife raised four children in the area and have been blessed with eleven grandchildren.

While he has no specific retirement plans at the moment and will take it day by day, Gerry is looking forward to spending time with his family and just simply enjoying his second act.

An Uptick in Industrial Oven Requests for Electric Vehicles

Posted on June 28, 2021 by jpwdesign

JPW has been designing and manufacturing ovens and furnaces for start-up companies in the electric vehicle industry for several years. Though lately, the requests have been more frequent and more specific. Mike Jameson with JPW Ovens Furnaces believes he knows the reason why this is the case.

Jameson says, “Mainstream automakers from around the globe are noticing that electric vehicles are the future. While the smaller start-ups have been researching, testing, and creating electric vehicles for years, the well-known automakers want to make sure their hats are tossed in the ring as they notice the demand from potential customers steadily increasing.”

The two types of ovens that are being requested most often are continuous process and batch. Jameson sees oven and furnace needs geared toward battery technology and research and electric motor processing testing. Requests vary from small-batch ovens to large continuous process ovens that expand to over 40 feet long.

Jameson adds, “Mainstream brands moving into the field are looking to have their ovens in a position to conveyorize so they can do more volume to supply products for assembly lines. They may begin using a batch oven but work their way up to a continuous process oven.”

When electric motor processing testing is needed, Jameson finds the ovens are being used to finish curing the product; when electric vehicle companies are looking requesting ovens for battery technology, ovens are typically used to test a battery’s stability in various temperatures without failing.

Jameson said he envisions the first true wave of electric vehicles coming to market soon. They will continue to improve as more people switch from the typical gas-operated vehicle to electric. He adds, “It is a fun time in history right now, and JPW is excited to be a part of it.”
