Batch Oven EL15

The Batch Oven EL15 is our most popular workshop size, the oven most coaters settle on when they move past samples and into steady daily production. The 1.2 x 1.5 x 1.5 m internal chamber is large enough to cure real workloads of brackets, fittings, small frames, hardware, and decorative items, while staying small enough to heat efficiently and run on a modest energy budget. It is the workhorse for a one-booth shop, a fabricator finishing its own parts, or any operation that needs reliable batch curing without the footprint or cost of a production-scale oven.

Chamber size and capacity

With 1.2 m of width and 1.5 m of both height and depth, the EL15 holds a far more useful load than an entry cube. You can hang a rack of brackets and fittings, stand small frames upright, or fill the space with hardware on multiple tiers. The taller chamber suits decorative items and short frames that would not fit a smaller oven. As always, space parts so air can move freely around every surface, because crowding causes uneven cure. A sensible loading pattern in this chamber lets you cure a meaningful batch in one cycle and keep the booth feeding the oven at a steady rhythm.

Heating and running cost

The EL15 is electric, which keeps both installation and energy use low for a workshop. There is no flue, gas line, or combustion hardware to install or maintain, and electric heat is clean and precise for the part sizes this oven handles. Energy use is modest: the chamber is well insulated and sized so it does not waste heat on volume you are not using. For a single-shift workshop this is the most economical setup to own and run. If you later scale to multi-shift or high-throughput work, our guide on gas versus electric curing ovens explains where gas heating starts to pay back its higher install cost, which helps you time the jump to a larger oven.

Cure profile and temperature uniformity

Maximum temperature is 205 C (400 F), comfortably covering the standard 200 C class cure window. Powder cures when the metal reaches its target temperature and holds it for the specified dwell, so the operator times the cycle from when the parts are hot, not from when the door closes. Lighter hardware reaches temperature quickly; heavier fittings and thicker frames need a longer soak. The insulated chamber and even air distribution keep the whole load close to setpoint, which matters when you mix part sizes in one batch and need them all to cure to the same standard.

Construction and controls

The EL15 uses insulated double-wall construction to retain heat and protect the work area. Controls come in analog or PLC digital form. Analog suits a shop that runs one or two fixed recipes and wants the simplest possible operation. PLC digital control adds a precise setpoint, repeatable programs, and a clear readout, which pays off when you switch powders often or want documented, repeatable cycles for customer work. The control holds a steady chamber temperature so each batch cures the same way as the last.

Where it fits in your line

The EL15 is the cure stage in a complete small finishing line. It pairs naturally with a Manual Powder Booth as a startup set, giving you spray and cure in two matched machines that fit a workshop floor. Upstream, a pretreatment wash or wipe-down prepares clean, contaminant-free parts so the coating adheres and cures correctly. Downstream, the cured parts come off the rack ready to pack or assemble. For a coater building a first line or upgrading from a borrowed oven, the EL15 plus a manual booth is the proven combination that handles the bulk of everyday job-shop work.
