Box Type Powder Coating Oven (Electric)
Box Type Powder Coating Oven (Electric)
About This ProductBox Type Powder Coating Oven (Electric)
The fan-assisted convection heating system provides homogeneous temperature at every point inside the oven with +/-3 C deviation. The PID-controlled digital system precisely manages temperature throughout the curing process.
Technical Advantages:
- PID digital temperature controller
- Fan convection: Homogeneous heat distribution
- High density mineral wool insulation
- SS304 interior lining
- 16 curing profile memory
- Overheat safety lock

What production it suits
A box type oven works in batches: parts are loaded by hand and unloaded when the cycle ends. It is the right choice for workshops with a limited daily part count but a wide part variety — each cycle can run a different part with a different curing profile. Because 16 curing profiles are stored in the controller, the operator does not search for settings every time. If continuous flow is required, that is, parts move along a line without stopping, a top-loading or tunnel oven takes over; the box type becomes the bottleneck there.
How the size is set
Internal volume is not picked from a catalogue. It is calculated from the largest part you will coat, plus hanging allowance and the clearance needed for air circulation. That clearance is not generosity: hot air moved by fan convection must reach every surface of the part, otherwise the rear face cures incompletely. An oversized oven burns extra energy in every cycle; an undersized one cannot fit the part and permanently limits capacity. Give us the dimension and we calculate the volume and the power required, within the 3–150 kW range.
Why temperature stability matters
Powder does not cure by temperature alone but by temperature and time held together. The oven works between 80 and 250 °C and holds ±3 °C uniformity with PID control. What that figure means in practice: the temperature difference between two parts in the same cycle never exceeds three degrees. In an oven that swings across a wide band, some parts under-cure at the bottom of the band while others yellow at the top — and the defect is only visible after the oven.
Body, insulation and maintenance
The inner body is AISI 304 stainless steel; rust and dirt shedding from a surface that oxidises at high temperature land on the curing wet film and become a defect directly. Insulation is 10 cm mineral wool: it shortens heat-up, stops the elements running continuously in steady state and reduces outer skin temperature. Routine maintenance is light — fan and element checks, the door seal, and an annual heat distribution check. The product carries a 2-year manufacturer warranty.
What to tell us when asking for a quote
Three pieces of information speed up the price: the dimensions of the largest part you will coat (width x length x height), how many cycles a day you plan to run, and your current contracted electrical capacity. The third is the most often skipped: the oven is built between 3 and 150 kW, and if your contract does not cover it, a capacity upgrade, switchgear and possibly a transformer come into play — an item that sometimes costs more than the oven itself. With these three we can size both the volume and a realistic total cost.

Frequently Asked Questions
What temperature should a powder coating oven reach?
Our box type electric oven operates between 80 and 250 °C with PID control and ±3 °C uniformity. The correct curing temperature is defined by the powder manufacturer, not the oven; the oven must hold that value steadily. The controller stores 16 separate curing profiles.
What production volume is a box type oven suitable for?
A box type oven is a batch oven: parts are loaded manually. It suits workshops with a limited daily part count and a wide part variety. For continuous flow, a top-loading or tunnel type oven is used instead.
Can the oven dimensions be changed?
Yes, every oven is built to your dimensions. The internal volume is calculated from the largest part you will coat, the hanging allowance and the required air circulation. You are not forced into a catalogue size.
How much power does an electric oven need?
Power options range from 3 kW to 150 kW. The requirement depends on internal volume, insulation thickness, expected heat-up time and daily cycle count. Give us the dimensions and we calculate it.
Why is the oven interior stainless steel?
The inner body is AISI 304 stainless steel. Combined with 10 cm mineral wool insulation and fan convection, it reduces both heat loss and contamination transfer from the wall to the part.
