2. Unit description
Function
Gravity convection ovens RE and mechanical convection ovens RF are suitable for drying and heat
treatment of solid or pulverized charging material, as well as bulk material, using the supply of heat. They
are designed for all standard drying and tempering tasks as well as sterilizing glassware. RF permits
shorter drying times.
The incubators RI are designed for exact temperation of harmless materials. They are designed to
cultivate microorganisms at defined temperatures.
Controller
redLINE chambers are equipped with an electronic PID-controller with digital display. The ovens RE and
RF have a temperature display and setting with an accuracy of one degree. The incubators RI have a
temperature display and setting with an accuracy of a tenth of a degree. The integrated timer can be set
to 0-9999 minutes. Also continuous operation is possible.
Interior and housing
The inner chamber, the pre-heating chamber and the inside of the doors are all made of stainless steel.
When operating the ovens RE and RF at temperatures above 150 °C / 302°F, the impact of the oxygen in
the air may cause discoloration of the metallic surfaces (yellowish-brown or blue) by natural oxidation
processes. These colorations are harmless and will in no way impair the function or quality of the unit.
The housing is RAL 7035 powder-coated. All corners and edges are also completely coated.
Heating and ventilation
redLINE chambers are heated electrically and ventilated naturally. Mechanical convection ovens RF are
ventilated by fan-assisted, forced-air circulation. The direct heating system provides an extremely precise
internal temperature. A thermoelement serves to measure the tempering of the interior, which is
controlled by the redline controller.
Temperature range: Ovens RE and RF: by 7 °C / 12°F above room temperature up to 220 °C / 428°F.
Incubators RI: by 7 °C / 12°F above room temperature up to 70 °C / 158°F.
Temperature safety device
redLINE chambers are equipped with a temperature safety device class 1 according to DIN12880. The
temperature fuse is triggered irreversibly if the maximum temperature of 229 °C / 444.2°F (RE, RF) resp.
110 °C / 230°F (RI) inside the chamber is exceeded.
Electrical connection
redLINE chambers are available for a 230 V, redLINE UL chambers for a 100-120 V power supply.
2.1 Scope of delivery
• redLINE gravity convection oven RE, or redLINE mechanical convection oven RF, or redLINE
incubator RI
• 2 trays
• Flat assembly bar for stacking (it is vital to keep them, as two flat assembly bars are required to stack
two devices, and each device comes supplied with one)
