Brief Product Description:

Avoid costly weld repairs by storing dry subarc flux in a Keen KF-600 flux storage oven. Keen has your large subarc operation covered with the large-capacity, KF-600, capable of storing up to 600 lbs. of subarc flux. Backed by 40+ years of welding industry insight and manufacturing expertise, Keen packed this flux oven with design, safety and energy-efficiency features unseen on other brands. Design features include: heavy-duty hopper design with welded construction; well-built supporting stand with welded construction; support bars at top of hopper to rest flux bags for easy loading; heavy-duty lid supports and much more. Keen’s innovative, energy-efficient design provides rapid heating of flux while reducing overall wattage and minimizing amp draw. Loaded with electrical and design safety features: digitally-adjustable, ON/OFF microprocessor-based controller with ±1 degree accuracy, manual reset high-limit fail-safe control and more.

Product Overview

About the KF-600 Flux Holding Oven – 600 lbs. Capacity

The Keen KF-600 is a floor-positioned, large capacity subarc flux holding oven. Subarc flux is top-loaded by way of a hinge-supported lid that is easily lifted manually, and discharged through a slide valve located on the bottom of the unit. Handy, fixed steel bars that stretch across the hopper opening allow the easy emptying of new flux from unopened factory packaging. The flux bags can be placed across these bars, cut open and emptied into the oven hopper. When flux needs to be removed, a container is placed by the user beneath the hopper to catch the granulated flux as it is dispensed. The hopper unit is securely mounted onto a stationary, heavy-duty stand.

The welding flux temperature inside the oven is regulated and controlled by a field-adjustable, digital controller with bright, LED temperature indicating display (user can switch from Celsius and Fahrenheit). This microprocessor is housed in a control box on the side of the flux oven hopper, along with a separate on/off indicating red light. This light enables users to quickly view from a distance if the oven is receiving power or has been shut off.

Heavy-Duty Construction

The Keen KF-600 subarc flux holding oven is ruggedly designed to withstand years of use in the most demanding industrial environments. Heavy-gauge steel is used throughout the unit and 2 inch thick, semi-rigid, high-density mineral wool in the oven walls and lid keeps the KF-600 flux oven well-insulated and energy efficient. The exterior features a durable powder-coated paint that is highly resistant to industrial environments and will stand up to years of use. The KF-600’s hopper has welded seams inside and out, and is securely mounted to our custom-built stand with heavy-duty screws.

Performance Heating

Thorough, energy-efficient and quick heating of welding flux is the hallmark of all Keen flux ovens. The KF-600 in particular has 27 / 1000W elements evenly dispersed throughout the flux oven hopper cavity. The elements are arranged inside the oven cavity from top to bottom with the last 3 elements at the very top of the oven; if a welding inspector opens the lid to test the temperature, he will get an accurate reading. When loaded with flux, no more than 2” of flux is without direct heating.

Our large-capacity flux ovens are designed to reduce watt density to the heating elements through a unique wiring series, greatly reducing overall power

consumption (The KF-600 is only 2666 watts) while increasing heat-up times for cold loaded flux. This eliminates the problem of flux fusing to the heating elements which is a common problem seen in competing brands (Fusing of flux often creates a “gumming” effect causing the granulated material surrounding the elements to meld together). According to our testing data the KF-600 can heat 600 lbs of cold-loaded subarc flux to 550F in approximately 4.5 hours, very quick compared to many competing models.

Quality Temperature Control and Electrical Safety

As standard equipment, Keen KF-600 flux ovens feature a UL® approved microprocessor with digital up/down temperature control and LED temperature-indicating display. The temperature reading can be displayed in either Fahrenheit or Celsius, and has a ±0.2 degree accuracy. Handy tactile increment/decrement keys on the controller’s water-resistant front panel enable easy temperature set point adjustment. The controller also features an on/off control mode.

Quality Insulation

Efficient heating design must be supported by quality insulation. The Keen KF-600 features a semi-rigid, mineral wool “board” insulation that is bonded together with a high temperature binder. It is highly thermally efficient and is installed within the walls and lid of the unit.

Optional Accessories

As an optional accessory, Keen offers slag screens that can be installed at the top of the oven chamber. Our slag screens are designed to be a sieve for filtering out contaminants in reused flux as it is being poured back into the flux oven hopper. The hole size on our flux oven slag screens is standard, but we can adjust the screen hole size if you have a different requirement. The slag screens are a fixed size according to the flux oven with which they are used.

Customization

We have the unmatched ability to customize any of our standard ovens, and/or design one-of-a-kind ovens for unique storage requirements. Welding codes are constantly changing, and Keen is ready to meet the demands of today’s welders.
