Get Help Choosing a SHEL LAB Oven

April 28th, 2015

SHEL Lab lab oven

Have questions before taking on the challenge of selecting the right SHEL LAB oven for your application? From benchtop and floor models to gravity convection, clean room, nitrogen purge, and vacuum ovens, SHEL LAB offers plenty to choose from across multiple heat processing applications.

Below you’ll find a brief introduction to the various types of SHEL LAB ovens available so you can rest assured you’ve selected the right oven when it comes time to make a purchase.

SHEL LAB Forced Air Ovens

SHEL LAB’s forced air laboratory ovens use blowers to force warm air through the interior chamber. SHEL LAB ovens use smaller holes on one side of the chamber than the other side to create greater velocity on one side and less resistance on the other as air moves evenly over your lab samples.

Drying or baking samples that may easily be blown around in the chamber? A gravity convection oven may be a better choice for your needs.

High Performance Drying, Curing and Bake Out Ovens

High Performance ovens are built to a strict standards and use a thicker gauge metal, highly precise air flow patterns, and higher velocity blowers. SHEL LAB’s HF series offers tighter uniformity over a large space, increasing drying and curing efficiency.

Gravity Convection Ovens

Gravity convection ovens use natural heat convection to allow warm air to pass gently over samples. Air exchange and moisture loss are adjusted using a top damper. As with all oven applications, the wider the damper, the more moisture is removed.

Clean Room Ovens

To prevent any flaking or dust from the oven entering a clean room environment, clean room ovens are constructed using 304 stainless steel with gasketed body panels to ensure insulation particulates will not escape. Interiors are equipped with a HEPA filter to screen all chamber recirculating air.

Vacuum Ovens

Vacuum ovens are very effective for decontamination and low moisture determination studies. They have been used for years in semi-conductor production to reduce oxygen exposure.

Dependable Laboratory Oven Design

All SHEL LAB vacuum ovens are built with a stainless steel chamber for exceptional durability. Our double plenum design meets UL, CSA and EU safety requirements resulting in a cool outer surface.

The doors on these units have positive latch handles with spring-loaded glass to facilitate a good vacuum seal without hinge binds that shorten the gasket life. A selection of gaskets (for specific applications) and a small bench top footprint increase the versatility of these ovens.

The unique cross-flow ventilation forces inert gas to fill the entire chamber. To achieve required vacuum levels, users can choose from a 3/8 inch orifice or a KF25 fitting to withstand heavy use and minimize draw-down time. Maximum permitted end vacuum is 10 μ. Leak rate is 10 μ per hour.

SHEL LAB stocks vacuum pumps and related accessories that are compatible with most applications. Our technical support team is available to advise on the perfect solution for your complete vacuum oven system purchase.

Heat Treating Applications: When to Choose In-House vs. Outsourcing

July 15th, 2013

For many businesses, the time will eventually come when it’s necessary to choose between using an outside heat treater and purchasing a heat treat furnace to handle your heat treating applications in-house.

When this day finally arrives, it’s important to consider several factors before making your decision. Heat treat furnaces are often used in tool rooms and other heat treating applications, and these applications generally benefit from the design and function of one our Cress heat treat furnaces (for a full list of available Cress Furnaces visit our Heat Treat Furnaces product pages).

Important factors to consider:

  • Load capacity & energy consumption – when heat treating, it’s important to consider the volume of production you’ll be treating. Energy used for process heating adds up to a sizable percentage of the total production cost, as maintaining precise temperature control is crucial. These costs will need to be factored in when deciding if it’s more affordable to handle in-house or not. For production-oriented applications, purchase of a heat treat furnace like those manufactured by Cress Manufacturing may provide real cost benefits.
  • Production deadlines and turnaround time for outsourcing – For most businesses, deadlines loom large. Outsourcing your heat treating may be beneficial if you have generous production schedules, but could create the potential for issues when deadlines are tight. Depending on these and the volume of production, purchasing a heat treat furnace can provide additional cost savings associated with sending products to an external heat treater.

Now you are armed and ready to make your decision! Which option will be best for you? Buying a heat treat furnace, or outsourcing your heat treating?

EPS Product Highlight: Industrial Curing Ovens

May 31st, 2013

Industrial curing ovens are used across many industries for a wide range of applications

From Aerospace composite curing to semiconductor and electronics manufacturing, curing ovens are often an integral part of completing an important process that ends in a finished component, part, or product.

The reason industrial curing ovens are often the last step of many processes is that curing is a process itself that creates what is often a final reaction, one that cross links composites to help the materials harden, thereby offering a strong and durable finish with much less risk for future damage.

At EPS, we offer many options for industrial curing, all of which can be customized to meet your specific application requirements. EPS Engineers are all experienced in the design of both continuous and batch ovens.

Some of the industrial curing applications our EPS industrial ovens have been used for include:

  • Epoxy curing
  • Powder coating
  • Composite curing
  • Adhesive curing

Visit our product pages to learn more about our custom industrial ovens, or contact us to discuss your particular application and see how EPS Ovens can custom design and manufacture an oven that will best suit your needs and your workflow.

Industrial Ovens – Continuous or Batch? A Quick Tutorial on the Benefits and Drawbacks of Each

May 1st, 2013

You know you need an industrial oven, and you know your application is unique enough you will need to have it custom manufactured to make sure all of your requirements are met. But now comes the big decision—will you choose a continuous style oven, or will a batch oven be better suited to your needs?

Great question! The answer? It really depends. Custom industrial ovens come in all shapes and sizes, from small to practically big as a house, and can be used for a broad range of applications. Some typical applications include:

  • Drying
  • Curing
  • Annealing
  • Aging
  • Stress relief

Batch ovens are a type of industrial oven that do just what the name implies, heat in individual batches requiring one heating process like those included above. The benefits of choosing a batch oven are best suited for applications that include greater variation in load volume. If you will be switching between various sized components, this may be your best option. The downside is that batch industrial ovens are generally less economical to operate since they require more handling and setup time in between batches.

Continuous style ovens offer the benefits of an industrial oven that can be operated at a continuous rate, thereby offering more economical options for high-volume production. In order to offer this type of operation, however, the continuous industrial ovens offer less operational flexibility and are better suited to applications requiring less handling and changeovers.

While this article outlines the two main types of industrial ovens, the options for customization are extensive, and it will be important to discuss your requirements fully with your oven manufacturer. For more helpful tips to consider when you’re ready to make an industrial oven, read our recent article featuring EPS President Ken Klein.

Purchasing a Lab Oven? 4 Ways to Ensure You Find the Right Fit for Your Application

April 17th, 2013

Laboratory ovens are used across multiple industries, so it’s not surprising that there is a large variety of laboratory ovens to consider when it’s time to make a purchase.

Below we’ve outlined what we think are the top 4 factors to consider for a laboratory oven purchase:

Temperature A simple concept on the surface, but this one has layers. Depending on your application (drying, curing, bake-out, etc.) your temperature needs may vary. And just as important: temperature uniformity. Temperature uniformity depends on a combination of factors, including type of circulation and also insulation levels. Let’s break this down by lab oven types:

  1. Forced air: Forced air lab ovens are often used for drying and curing applications, and function by forcibly circulating heated air throughout the oven cavity in order to maintain uniform temperature
  2. Gravity convection: Gravity convection lab ovens operate on the basic principle that warm air rises, pushing down cooler air where it’s heated in turn.  This can be useful for lighter weight objects, as air flow is gentler than that of a forced air lab oven.
  3. High performance: High performance lab ovens are used when an extremely high level of precision is needed for your oven application. High performance ovens can maintain this level of precision for prolonged periods of time and relatively continuous operation.
  4. Clean room ovens: These ovens are used for applications that happen in “clean” rooms, or rooms that require a controlled level of environmental pollutants. Clean room ovens often have additional product features designed to meet these requirements.

CapacityCapacity is a clear factor in choosing the right oven. EPS alone carries more than 20 different capacity laboratory ovens. A clear understanding of just how much capacity you need ensures you won’t end up paying for more oven than you need.

Oven features These include things like shelving design or temperature controllers. Will you need to ramp up and hold your temperature, or will your application require multiple temperatures are met and held during a cycle?

Reputable dealer Really, you should consider the reputation of your seller within the industry. Sure, you can make a quick purchase on eBay, but you may be missing out on key product information by not speaking with an experienced distributor who understands your needs and knows which questions to ask to help you find the oven that’s the best fit.

At EPS, our sales team have unmatched knowledge and industry expertise that can help guide you and ensure your purchase meets your needs exactly.  EPS carries a large selection of high quality SHEL LAB lab ovens and Cascade TEK lab ovens to choose from.

Two Types of Cress Heat Treat Furnaces – Which is Right For You?

December 13th, 2012

Heat treat furnaces from Cress ManufacturingChoosing the right heat treating furnace for your application can be a tricky process, as you are inundated with a seemingly unending parade of heat treating categories, feature sets and so on. We’re here to make the decision just a little bit simpler, with a brief explanation of the two types of Cress furnaces.

When it comes to Cress heat treating furnaces, there are two main types available for sale:

  1. Heat treating furnaces
  2. Draw furnaces

EPS carries the entire line of Cress Heat Treat Furnaces, including lab furnaces, tool room furnaces, medium and large production furnaces, and even drop bottom quench furnaces for the solution heat treatment of aluminum

Heat treating furnaces operate using higher heat output than draw furnaces and are used to harden, strengthen and reduce residual stress of materials. Furnaces in this category generally have a temperature max of around 2250 degrees Fahrenheit, and are suitable for most general use in the shop or lab.

Draw furnaces, on the other hand, are used for lower-temperature applications including annealing, tempering and stress relieving. Normal maximum temperature for a draw furnace is closer to 1250 degrees Fahrenheit. Draw furnaces are most often used to heat a quench hardened material to below its transformation range in order to reduce brittleness and relieve internal stress.

Each type of furnace comes in a range of sizes, from small lab furnaces to large capacity production furnaces.

For more than 20 years, EPS has teamed up with Cress Manufacturing to provide our customers with the ultimate furnace purchasing experience, as we work together to ensure we understand the needs of our customers and provide them with the correct product for their individual application.
