This characteristic helps solve the problem of operational safety when operating in a Class 1, Group D processing environment by removing an ignition source. Three models of the Friction-Aire family are listed by Underwriter's Laboratories. These chambers are the first and only electric ovens to have ever been so listed. Friction-Aire ovens are a sound solution to the Class 1, Group D processing applications. If you would like more information or need help in choosing the right chamber for your specific application requirement, please let us know. We would like to be of service. How it works The Friction-Aire oven provides a controlled environment with 100% straight-line proportional temperature performance without heating elements or electrical controls. It uses a unique high velocity air-flow system Over-temperature protectionNon-electrical system powered by its own secondary bellows responds to its own sensing element. A spring-loaded vent with inlet area greater than control vent area is latch-closed by reset lever on control panel. If main control fails, properly set OTP safety trips vent latching mechanism to lock vent in the fully open position. Resulting increase in exhaust capacity immediately drops chamber temperature. Vent must be re-closed by manually pressing the reset lever. Oven operation continues at safe temperature. Control operationA temperature-sensitive bellows regulates fresh ambient air to a blower system. Temperature is set by control dial. As the temperature rises with blower operation, bellows expand to open and position the control grate. More air enters the system causing sharp temperature curve-off and stabilization. Adjustable by-pass damper vane establishes control inlet pressure. When horizontal, the damper restricts path of blower only through control. Since this reduces CFM and velocity, heating is minimized for control at lower temperatures. When damper is vertical, system recalculates at maximum for maximum heat. While a large air volume must be moved to generate heat, much of it passes through the by-pass chamber surrounding the work chamber. The small percentage passing through the inner chamber is practical for most applications, to move air through a prescribed pattern to generate heat. This concept offers a number of advantages. Solid side walls are available for applications involving the drying of lightweight powders and other sensitive airborne product loads. Temperature uniformityThere is no central heat source in the system. Heat is generated within the air as it moves using a blower to develop turbulence and friction. As a result there are no hot spots, and no points within the chamber that exceed the indicated air temperature. Temperature stratification problems are therefore eliminated by Friction-Aire. Natural interlock of blower and heatThis characteristic means that if the motor/ blower system fails - the only source of heat - the chamber temperature will automatically drop. No dangerous temperature runaway conditions exist in this system. If air circulation stops, there are no uncontrolled heating elements to increase oven temperature above the set point of the control. The need for a timed purge cycle is eliminated to avoid igniting the air/solvent mixture at start-up. When product is initially placed in the oven, a high concentration of volatiles is present due to rapid evaporation from the product. When a conventional heating element design is used, this concentration must be diluted by a timed purge cycle prior to air heater turn-on. Since there is no ignition source, Friction-Aire eliminates the need Built-in over-temperature protectionThe Friction-Aire incorporates a unique and intrinsically safe non-electrical over-temperature protection system. It is powered by its own secondary bellows. The bellows responds to its own sensing bulb. A spring loaded vent with an inlet area greater than the control vent area is latch-closed by a reset lever on the control panel. If the main control fails, the OTP safety sending bellows trips the vent latching mechanism to lock the vent in the fully open position. The resulting increase in exhaust capacity immediately drops the chamber temperature. The vent must be re-closed manually by pressing the reset lever. Oven is then ready to continue operation. Fast cool-down ratesHigh-velocity air generated by the blower system is fully controllable within the work chamber and reduced to a practical rate during the work cycle. Fast cool-down is an inherent capability of the system. Typically, an empty oven temperature will drop from +150 C to +50 C in thirty minutes. Greater cost-effective performanceEnergy savings over conventional ovens are substantial. There is less to maintain and service with Friction-Aire, due to the type of construction and basic operational concept.   Friction-aire ovens -- like all Blue M equipment -- come complete, ready to perform as specified. The various accessories Blue M has available for these chambers add a dimension of service or function for meeting a number of special needs. Your Blue M representative is equipped to explain these items in detail. Special stainless steel side walls FRICTION-AIRE work chambers can be provided with easily removable solid stainless steel side walls. These cause the major portions of circulating air to by-pass the workload. This provides the equivalent of a gravity unit to allow the processing of powders or other loads that could be affected by high velocity airflow. Since these side walls will tend to interfere with the basic Friction-Aire principle, they will cause a reduction of approximately 30% in the available heat input of the oven. An increase in run up time and a reduction in maximum practical operating temperature will result. Spring-wound monitoring recorders These recorders are available to monitor and record chamber performance. They are not connected electrically or mechanically to the control system but operate independently and directly in response to actual chamber conditions. These are dual scale instruments with either one or seven day movement. Other accessories include: Matching cabinet type floor stands for bench models 9 Casters Shelves Lead-in port Friction-aire Typical operating characteristics Temperature range:+ 25° C above ambient to +150° C (302° F) Typical air temperature uniformity:at + 100° C: ± 0.5° CRun-up time: (no load) to + 150° C: 120 minutes Cool downtime: (no load) to +50° C: 30 minutes Control accuracy: ± 0.5° C Drift: (over 24-hour period) at +50°C:± 1 C at + 100°C: ± 0.75° C at + 150° C: ± 0 50° C Average velocity: (adjustable) Maximum: 400/FPM Minimum: 100/FPM These three models have been listed by Underwriter's Laboratories for operation in Class 1, Group D hazardous locations. They are ideally suited for the testing and processing of hazardous materials, paints, solvents and lacquers. There are no heating elements in the chamber and no inherent hot spots to create potential danger. Tests show that load temperature follows closely behind chamber temperature. If the application calls for the processing of hazardous materials over extended periods, the load temperature and chamber temperature will be practically equal all of the time. When chamber and load reach complete equilibrium they will remain so indefinitely until the temperature is deliberately changed. Even if spillage of flammables inside the chamber occurs, danger is minimized since any surface the liquid encounters is only as hot as the interior environment.
