This Unitech RED EVO 3 is a stenter and dryer — a finishing machine used in textile manufacturing to simultaneously stretch, heat-set, and dry fabric to precise dimensional tolerances. Sometimes referred to as a tenter frame, this class of machine is a core piece of equipment in fabric finishing lines, handling both dimensional stabilisation and drying in a single continuous pass. Unitech is a recognised Italian manufacturer of textile finishing machinery, building equipment for woven and knitted fabric producers across the apparel, technical textile, and home furnishings sectors.
This machine was manufactured in 2003 and subsequently refurbished in 2020, bringing it to a renewed operational condition. It is located in Italy and is offered for sale used. The oven runs on natural gas, with burners supplied by Weishaupt, a well-regarded German combustion equipment manufacturer. The oven chamber spans 20 metres in total, divided into ten individual sections of two metres each, providing substantial dwell time and precise zone-by-zone temperature control across the fabric's passage through the machine.
The working width is 2,400 mm, making it suitable for a broad range of fabric widths in both woven and knitted constructions. Entry arms extend six metres, allowing for smooth, tension-controlled fabric infeed. Spreading rollers at the entry point assist in presenting the fabric flat and even to the chain system. The transport system uses a vertical chain configuration fitted with pins and an anti-depinning system, which prevents fabric from releasing unintentionally during the heat-setting process.
Additional processing equipment includes a selvedge gluing device, a steamer device, and selvedge trimming devices at the relevant points in the line. A cooling unit is integrated to bring the fabric down to a manageable temperature before delivery. Fabric can be delivered either in plate (folded) form or as a big roll, offering flexibility in downstream handling. The machine is also equipped with a PLEVA TDS 95 device, an instrument used for monitoring and controlling fabric moisture and temperature parameters during the finishing process.
