Superior Thermal Performance
for Heating and Cooling
The New MK7 platform has revolutionized the reflow industry with several new and groundbreaking designs.
The low-profile modules provide lower Delta T while reducing overall energy consumption. New flux
management options offer exceptional capability and reduce overall PM times. New cooling systems offer best
in class cooling rates and low exit temperatures while providing exceptional thermal separation between zones.
We invite you to visit any one of our 3 demo locations to run profiles and see for yourself the strong advantages
the MK7 can bring to your process. Or if you prefer, send us your toughest board and we will run profiles and
generate the data for you. We are happy to work with you to create a custom configuration to fit your needs.
New Heating System
Enhanced low height heater module and large
impeller provides the lowest delta T’s on
product with improved air flow and uniformity!
New Cooling System
A variety of module types and systems are
available, tailored to the application including the
most demanding lead-free profile requirements.
A super cooling system option is available for
high mass applications that can provide cooling
rates >6°C/sec and exit temperatures below
50°C.

Excellent thermal performance is achieved with improved designs for heating and dynamic control, while
energy usage is reduced with improved sealing and insulation. The Energy Management System on MK7
ovens provides smart control when off-loading of production to further save energy consumption.
Level 1:
▪ Slow down exhaust
blower
Level 2:
▪ Slow down zone blower
▪ Minimize or stop N2
▪ Slow down chain speed
Level 3:
▪ Load Standby recipe
Level 4:
▪ Cool down
Standby Mode
Results:
~50% kW less
~60% N2 less
Loading and no
loading, Delta T < 2°C
Energy Management System on MK7 ovens provides smart control when the production line is idle to further
save energy consumption.

New Designs Minimize Preventive
Maintenance Effort & Time
Due to the new heat exchanger design with
chilled water, the water box flux management
system gives superb flux filtration
performance while keeping maintenance and
cleaning easy during PM. The enlarged
capacity of provides longer interval between
PM than other flux management systems.
Pit-Stop features are an innovative way to reduce
PM times by reducing overall oven downtimes.
Parts involved with Pit-Stop features can be
removed and exchanged without cooling down the
oven, so production can be resumed right after the
exchange.
The quick release cooling grill with anti-flux
dripping design simplify flux cleanup in the
cool zones, further reducing overall PM effort.
In close cooperation with our advanced materials
provider, HELLER’s new low temperature catalyst
can help remove flux during reflow resulting in a
clean process chamber.
