TAF and TFF Walk-In/Truck-In Furnace

TAF and TFF walk-in/truck-in furnaces are ideal for large batch processing that requires high temperatures. Common applications for these versatile furnaces including: aging, bonding, curing, drying, finish baking, heat treating and stress-relieving. Horizontal, recirculating air flow creates precise, consistent temperature uniformity throughout the furnace.

High temperature applications that include flammable solvents or large amounts of moisture removal are best suited for TFF model furnaces. TFF Class A furnaces are specifically designed to meet NFPA 86 requirements and include a pressure relief panel, purge timer and exhaust fan.

TAF and TFF furnaces offer standard temperatures up to 537℃ (1000℉) and are equipped with the Protocol 3™ control system. All models are fully assembled and factory tested prior to shipment. These high performance furnaces also feature stainless steel interior, end-of-cycle and high-limit indicators.

The Despatch TAF and TFF Walk-In /Truck-In Furnace features a sturdy, welded, double-wall construction, seven inches of glass fiber insulation, and heavy-duty high temperature door gaskets. Stainless steel interior minimizes corrosion problems and provides long life.

Advanced control | Protocol 3™ is a microprocessor-based temperature and hi-limit controller with large LCD display and real time clock for auto start capability. The LCD display shows temperature readings along with clear, detailed information on oven status. Protocol 3™ features three operating modes for quick and easy operation: Manual mode, Timer mode and Profile mode. The data-logging functionality enables reporting and analyzing and data files can be exported via the controller's USB port. Modbus RS485 communications are included for easy data access.

Remote operation, programming and data logging | The Despatch Protocol Manager network utility software enables the operation of up to 32 Protocol 3™ and/or Protocol Plus controllers from a single, remote PC using RS485 communication.
