1.1 The APEX range
The Apex range of fan ovens comprises three models, of 30, 60 & 120 litres chamber capacity,
known as models AX30, AX60 and AX120
Temperature control is by an easy-to-operate digital unit. The oven temperature range is from
40°C 250°C. The minimum temperature may be higher if the ambient temperature is above 30°C.
Heat up times to 250°C without load and on a 240V supply are approximately 25 minutes; with
load or at lower voltages these times are increased.
A matching digital timer is available to order, or may be retro-fitted*. A second option is a
hydraulic thermostat overtemperature control device. Without the overtemperature device the
ovens conform to BS 2648; with the device they also conform to DIN 12-880 class 2. There is also
the option of a locking handle.
* AX120 at 110-120V – please enquire
Temperature accuracy is enhanced by the use of a platinum resistance thermometer as the
temperature control sensor. A simple air-flow adjustment may be made by movement of a sliding
vent control mounted at the back of the oven. Typical air-flow with the vent open is 1850
litres/hour at 100°C, giving exchanges in chamber volumes per hour of 65 (AX30), 28 (AX60) or
14 (AX120).
The door is hinged on the left for easy loading and unloading of work.
1.2 Voltage
These models must be ordered correctly to match the supply voltage. The voltage alternatives are:

Single phase 220V-240V

Single phase 110V-120V
1.3 Switches and Lights
When the oven is connected to the electrical supply, and the instrument switch is on the controller
is illuminated.
