Why HIX

Increased Productivity

Our customers have one thing in common – the need for increased productivity. This can evolve from increased throughput, improved quality rates, a smaller footprint, reduced energy costs, or reduced labor. Through our application-centered approach, we are consistently successful in improving productivity and efficiency for our customers. We design curing ovens, conveyor ovens, batch ovens, annealing ovens, and more.

 

Design

HIX Industrial Ovens & Dryers has a distinct advantage over the competition, we design our products specific to meet customers’ needs tapping into 50 years of design innovation! Our ovens and dryers have design characteristics which are particularly beneficial. These characteristics include: custom manufactured IR heating elements, an extensive list of options, quality part selection, easy maintenance access, high energy efficiency, and experience with modification and design for specific substrates. Most importantly, we design around your product!

Energy Efficiency

Energy savings equals money savings. Here is what HIX Industrial Ovens & Dryers does that makes our ovens and dryers the best.

Heat Types

Infrared

HIX IR panels are custom made in-house to provide us the ability to “fine tune” the element for a particular watt density or wavelength that is most receptive to any given substrate type for maximum energy transfer efficiency. This provides for a more efficient heating system because we are able to control the amount of resistance in each panel to ensure the lowest amount of energy possible is required to for a substrate to reach the required temperature.

Infra-air

Air circulation is added to IR heat when vapor barriers are likely, or volatiles need to be evacuated from the oven chamber. The combination of IR heat panels and air circulation helps to maximize drying and curing processes, as well as, ensure a safe heating environment.

Electric Hot Air Convection

Electric Hot Air Convection systems provide a distinct set of advantages over IR panel heaters. Electric hot air convection ovens use stainless steel-finned strips heaters that are heated to a set temperature. Air is then circulated across the finned strips to provide heat into the oven with a very low temperature variance.

Gas Fired Hot Air Convection

Gas Hot Air Convection systems provide a very similar set of attributes as electric hot air convection. A gas burner is installed and calibrated to provide a proper amount of BTUs based on the product and process needs. Gas burners come in various sizes and can be installed in multiple locations and quantities depending on the size of the oven or dryer.

Gas types which can be utilized are natural gas, propane, butane, and blends.

IR and Hot Air Convection Combination

For unique processes required dual heat sources simultaneously or consecutively.
