Experience. Rack ovens made by wachtel ®
stand for long service life and high operational reliability.
High-quality materials for heat exchanger, baking chamber
and front and exterior paneling add a very appealing
appearance to this concept. The individual components
are not bolted but carefully and securely welded. Each
COMPACT and COMET rack oven stands on an extremely
strong stainless steel base plate. These are decisive factors
for a long and reliable service life.
wachtel ® rack ovens boast exceptionally large baking
surfaces with minimum space requirements. Due to its
unusual height, the baking chamber can accommodate
racks with 20 layers as standard while maintaining the
technically required minimum layer pitch of over 84 mm.
Compared to ovens accommodating racks with only 18
layers, wachtel ® rack ovens produce 11% more volume
with the same baking surface.
wachtel ® engineers are especially proud of the cross-flow
fan installed in the COMPACT F which assures an absolutely
consistent and uniform air distribution and flow. This results
in optimal energy efficiency at the slowest possible air flow
while baking products of supreme quality. Continuous
baking is not a problem due to the large-capacity steaming
unit generating sufficient steam at any time.
With the computer controls as a standard feature, wachtel ®
rack ovens are easy to operate. If you need an alternative to
oil or gas operated COMPACT ovens , the electrically operated
COMET rack ovens would be your choice.

Innovation. The COMPACT K STIR by
wachtel ® was the first rack oven in the world that baked
with a combination of radiation and convection heat. So far,
this combination has been applied successfully in wachtel ®
deck ovens.
The STIR radiating chamber walls increase the infra red portion
in the heat by up to 90% which results in baking times
reduced by 30% and more flexibility for other products.
Moreover, the quality and freshness of the baked product
are improved.
The design incorporating a patented large-surface heat
exchanger boasts even more benefits. Compared to conventional
rack ovens, the energy consumption drops by up to
30%. The exhaust temperature is only 15°C (59°F )
above the temperature in the baking chamber. The large
heat storage capacity of the baking chamber minimizes the
temperature drop when charging the oven. Dough pieces
are warmly greeted and reciprocate with premium quality.
The patented COMPACT K STIR can be operated either by oil
or gas.

Robust design for a long service life.
Rack ovens in line with the wachtel ® standard.
High-quality workmanship for compelling baking
results. The ovens of the Compact line are supplied
with gas or oil burner.
Produce large volumes at lower costs.
The 2.8/2.10 double rack oven accommodates
2 racks with 20 layers each. The advantages of
two COMPACT ovens combined in one double
oven with up to 24 m 2 baking surface: Less space
required, increased energy efficiency and reduced
investment costs.

COMET – the electrically heated alternative.
The perfect alternative wherever it is reasonable
and economical to rely on electrical power with
all its inherent advantages. Connection to a flue
gas chimney and a burner are not
required. Clean, quiet and reliable.

Basic accessory
The SHOPMATIC control: Easy and safe operation.
29 automatic programs and one manual program are easily managed
via scroll wheel or key pad. Comfortable operator guidance through
display prompts. The SHOPMATIC control is network-capable as are
all wachtel® computer controls.
Cleary arranged and comfortable.
Programming, monitoring and controlling of
baking programs is made easy with the help
of the wachtel ® WinServer which also allows
selection and downloading of programs at
the oven. The WinServer software includes
comprehensive control functions and allows
connection of a printer as an option. For the
electrically operated COMET power management
programs are available.
The OX C Computer control makes your daily work easier and safer
by programmed baking parameters. The large display screen clearly
shows all relevant program data. Comfortable data input at the scroll
wheel or touch screen. The OX control can be linked to a network as
any PC so that your oven becomes internet-compatible.
The “Quick Start” burner.
A new generation of oil and gas burners
provide quick burner start without purging
which significantly reduces the temperature
drop after loading. Use less energy but
produce better quality
(energy savings up to 11% ).
Service-friendliness in mind. Service points for
burner, cross-flow fan, control panel and drive
elements are arranged behind service doors in
the front for easy access which saves costs and
makes maintenance easy.
The heat exchanger. Energy-conscious
baking is the focal point in the development
of our baking ovens. We proved this with
the STIR technology. The other COMPACT
oven models are also specially designed
constructions with optimum heat storage
surface for maximum efficiency. They are
particularly enduring and reliable through
exclusive use of highly heat resistant special
grade stainless steel.
