RTC D-SERIES OVENS
The D-Series of infrared convection ovens are designed for processes requiring close control of both temperature and atmosphere.  Primarily intended for thick film drying, adhesive and epoxy curing, these ovens can also perform many other lower temperature processes requiring air and nitrogen operating atmospheres. 

RTC T-SERIES OVENS
The TA series of micro ovens are especially designed for use in situations where space is at a premium.  The oven fits on a table top or work bench and can be easily transferred from one location to another.  The variety of heating jobs this small, conveyorized unit can handle are virtually without limit. 

RTC HT-SERIES FURNACES
The HT-Series furnace operates in mid-range infrared by combining both infrared and ultra-violet heating elements.  The combination of these two enables the furnace to reach temperatures of up to 1300°C.. 

RTC LA-SERIES FURNACES
An extremely versatile, general-purpose laboratory furnace used for experimental, prototype, or low-volume processing.  Its flexibility, temperature range, controlled-atmosphere capabilities, availability of options, and process applications are similar to larger models. 

RTC S-SERIES FURNACES
The fastest and most efficient production furnaces available for high-temperature semiconductor and thick-film processing.  
High production yields and through put are achievable due to the design's quick start-up and change over time, precise and repeatable temperature profiles up to 1000°C..

RTC TFA-SERIES FURNACES
The TFA-series of infrared furnaces are designed for processes requiring close control of both temperature and atmosphere. Primarily intended for thick film firing of precious metal compositions and air fire-able resistors. 

IR heating, unlike convection heating, provides heat directly to objects without first heating the surrounding air. IR waves excite molecules within a substance (thus generating heat) but pass, generally undisturbed through the surrounding atmosphere. Other substances such as glass, ceramics and some organic materials are also transparent to IR waves. Objects suspended in these media can, therefore, be heated directly by IR waves without directly heating the supporting media. RTC is currently using two types of infrared heating, near infrared and medium-range infrared. Near infrared furnaces can reach temperatures up to 1000°C, while mid-range infrared furnaces are able to reach temperatures up to 1300°C.

The simultaneous placement of UV and Infrared heating lamps inside the same furnace chamber is a new, patent pending, RTC technology that will work to temperatures as high as 1000°C. This highly sophisticated system incorporates separate cooling and electrical systems. Depending upon installation specifications, the cooling jackets support either air or water cooling. The special mercury vapor lamps inside cooling jackets supply the UV radiation.

This unique configuration is supplied to perform heat transfer through the indirect transmission of heated gas. In this type of furnace, the heating chamber temperature is maintained by heating the surrounding air. Convection is regularly used in surface mount reflow soldering when the components are different sizes. In this configuration, IR lamps are used to heat a metal chamber through which air is circulated. Currently RTC convection furnaces operate to temperatures as high as 600°C.

In some applications, conduction heating is more desirable. RTC furnaces can be configured to run in conduction operations where the standard IR heating lamps are placed below the conveyor belt only. A special high-density conveyor belt is cycled through the heating chamber to block the transmission of the IR radiation and absorb the transmitted energy. The energy output from the lamps is transferred directly to the conveyor belt itself. Any product in direct contact with the conveyor belt will absorb the stored heat energy via conduction. Two additional conveyor systems are used independently to avoid heat loss that would occur while the conveyor belt is in the cooling section and any baffle modules.
