P-FA Fast Ager

Description:

 

 

The PRIALTEX FAST AGER type P-FA is suitable for fixing both reactive or indanthrene (VAT) dyes in two-phase mode, with temperatures between 135°C and 145°C.

Several machine sizes are available: P-FA10, P-FA12 and P-FA18 (fabric capacity 10m, 12m, 18m respectively). To extend reaction chamber fabric capacity, a different configuration with a double passage is also possible: P-FA10/18, P-FA 12/22, P-FA18/34.

A typical layout includes  an horizontal impregnation mangle and a reaction chamber. On request is also possible to have an oxidation path in air. Entry and exit can be completely personalized in accordance with customer needs.

The horizontal mangle is equipped with two high thickness rollers. One of them is chromium-plated, it is motorized and touches the fabric printed face; the other roller is rubber coated and touches the fabric back face. Two pneumatic bellows activate mangle pressure. A doctor blade is installed on the chromium plated roller. An AISI 304 trough with two basins for chemicals allows to impregnate by nipping (kiss system) or by dipping. The chemicals level is controlled by two sensors installed on both basins. Chemical feeding pump, feed and drain valves are included too. The trough can be pneumatically raised (Ready to work position) or lowered (cleaning position).

The reaction chamber is manufactured with double-walls steaming plaques, made in 3 mm thickness AISI 304 stainless steel, bended and enforced. The chamber is insulated with panels made in painted steel sheet containing high-density wool rock. The chamber is also provided with doors for easy maintenance. The roof is made in 3 mm thickness AISI 304 stainless steel, it is heated with pipe coils fed with steam and it is insulated with wool rock to avoid water drops. To realize the fabric path, inside the chamber are installed one upper pulling roller and other driven rollers. All rollers are completely AISI 304 made. An AC motor-gearbox drives the pulling roller, meanwhile the other rollers are driven by a chain trasmission. The rollers bearings are installed outside the chamber to easily perform their maintenance without enter in the chamber. The driving chains are installed outside the chamber too (with safety protections) to easily tension and maintenance them. An automatic fabric feed device is included. Furthermore an external electrical super-heater with PED certification is provided: it is equipped with steam inlet/outlet temperature control and resistance max temperature control. The steam exhaust fan is made in stainless steel AISI 304. The steam flow is automatically controlled by a pneumatic valve, a shut-off valves group and a steam flow meter.
