Project Background

At Keen Industrial Ovens, we receive calls everyday from a wide variety of clients, each with their own unique preheating requirements. The K-TLFC13.5 is another example of a fully customized oven with specific features requested by the client to enhance productivity.

The maintenance, repair and overhaul division of a transit bus operator contacted Keen industrial ovens with a heat process requirement that involved preheating two-drive engine stator assemblies in order to separate the stator from its aluminum housing. The transit bus operator was in the process of converting existing conventional buses to hybrid-drive systems, and a part of the process required preheating the stators in an industrial oven. A custom industrial oven was designed specifically for the application, the K-TLFC13.5.

Brief Product Description:

The Keen K-TLFC13.5 is a floor level, horizontal air flow, forced-convection, top-loading industrial oven. This heavy-duty batch oven is an excellent low cost solution for a wide variety of heat processing applications. Horizontal airflow is produced by a 3/4 horsepower motor mounted on the back of the unit, and is used in conjunction with a custom, in-house manufactured plug fan system for efficient, even heating inside the oven cabinet. Forklift pockets at the oven base allow for easy transport of the unit.

Applications:

Keen industrial ovens are used in a wide variety of industries for many different applications. Keen K-TLFC13.5 forced-convection industrial ovens can be used for annealing, heat-treating, curing, drying or simple batch processing of parts for preheating and postheating. Our industrial ovens are produced in the USA with the highest quality material, components and workmanship.

Frequently Asked Questions

Can Keen K-TLFC13.5 industrial ovens be customized to suit my application?

Yes. Keen industrial batch ovens are used in many different industries for a wide variety of heat processing applications. Each Keen customer has a unique heating application, part size and temperature requirement, and a customized batch oven is often the most effective choice for their specific heat processing needs. If your parts require pre-heating or post-heating before installation, welding or assembly, Keen can custom design an industrial batch oven tailored to your specific process. Just call us 1-888-512-2870.

Can you tell me more about the Keen plug fan system installed on Keen K-TLFC13.5 vertical forced convection batch ovens?

Keen’s proprietary plug fan blower systems offer great advantages over competing industrial ovens . Aside from the motor itself, the systems are completely custom manufactured in-house and specifically designed for use on Keen industrial batch ovens. The system is comprised of a motor, housing, shafts, plenum, fan and when in operation, the system is responsible for producing forced convection air flow on Keen industrial ovens. Depending upon the customer’s application and the type of Keen industrial oven selected, we offer horizontal or vertical forced convection systems to enhance process efficiency and thorough heating of parts.

Can you tell me more about the door gaskets used on Keen industrial ovens?

Oven door gaskets are a critical component for industrial ovens because the gasket must provide a tight seal and serve to minimize heat loss from the oven cabinet and prevent intrusion of moisture and dust (and if the application requires it, air) into the cabinet. At Keen, we use the highest quality oven door gaskets available. Made in USA, our gaskets are designed to provide a high temperature thermal seal on Keen industrial ovens with a maximum continuous operating temperature of 1000°F. They are constructed of a 304 stainless steel knitted wire core, overbraided with Type E fiberglass. The random spacing design of the braid allows Keen to effectively seal corner radii and structural anomalies.

What type of heating elements are used on Keen industrial ovens?

We install UL/CSA approved incoloy sheathed tubular heating elements on all Keen industrial ovens. Tubular heating elements are versatile products that transfer heat efficiently by convection or radiant heating to air and gases. They can be utilized in free convection or forced air convection ovens. Incoloy is a high-performance alloy that has excellent mechanical strength, and is a common high-strength sheath material for elements used in industrial ovens.

I would like a different shelving configuration. Can Keen offer a different type of shelf system for the K-TLFC13.5 heat treat oven?

Yes. For Keen custom industrial ovens, fabrication and design of shelving is specific to the customer’s process and can consist of flat perforated, removable, vertically adjustable, cradled, stackable baskets, trays and much more. Shelving in our line of welding consumable storage ovens is specific to the type of consumable being stored and storage capacity. We can produce a variety of configurations to enhance your heat processing efficiency.
