The most advanced Convection Batch Oven
for soldering and heating tasks
that demand the highest level of process control.

Until December 2018, the Best Batch Oven ever made was the X-Reflow306/S.

But the world changes rapidly. Following requests from electronics industry leading companies, Bokar International developed another unique, larger, faster, hotter, better sealed oven and equipped it with an on-board Residual O2 Monitor and 8-Channel Temperature Data Logger.

XSO- Convection Super Oven

The XSO SuperOven will enter limited production in June 2018.  It is not replacing the X-Reflow306/S, which still  is the most advanced Batch, Bench Top, Full Convection Oven today affordable for most. 

The new Super Oven is taking the place of the Top of the line. It is the fastest, the most powerfull and also will have the PC program allowing operation of the oven from a PC.

In summary, XSO SuperOven between the Batch Ovens is like Bugatti Veyron among Super Cars

12”x12”x1.75” (305x305x45 mm)

Temperature range

30°C to 350°C

Number of Zones

Purging, to push oxygen out + three to nine zones, set by the operator for each program. Last 2 zones are cooling zones. Total up to 10 (ten) zones, as needed.


2 Heaters (Front and Rear) 3,45kW (230V) and 3.45KW (208V) 
(Please specify voltage to receive correct heaters)

Max. PCB size

12”x12” (306x306 mm)

Supply Requirements

30 amps, 230V 50/60 Hz  (Max power consumption: 6.9 kW)

Advanced Cooling Module

Separate box connected to the oven via pneumatic and electrical lines and to the source of N2 or shop air.

Cooling media: Nitrogen or Shop Air (or both). Temperature to cool to and the SCFM (l/min) of the cooling media defined by the operator in the program.

Cooling gas enters the heating chamber and is distributed to the top of the heated object via 16 openings on 4 sides of the chamber. In soldering applications advanced cooling produces more reliable soldering connections and helps to handle heated objects after the heating cycle.

Opening and closure of the exhaust port during cooling cycles is automatic.
