ACCUDRY

STANDARDISED LABORATORY TUMBLEDRYER

Textile Laboratories, throughout the world, carry out a wide range of tests, in which domestic laundering conditions are simulated. Standardised washing machines are universally used but so far, no equivalent standardised ‘domestic’ tumble drying machine has been available. 

Laboratories have been compelled therefore to use normal home laundry dryers, purchased from high street retailers- with predictable problems of wide variations in performance from machine to machine, and between different manufacturers. There have also been widespread problems of machine reliability and of continuity of supply of particular models. Normal domestic tumble dryers are also inflexible, having- at best- two fixed temperature settings, with a broad temperature tolerance.

Responding to this challenge, we have designed and developed Accudry, the world’s first standardised Tumble Dryer.

Accudry is an air-vented, reverse- action, standardised Tumble Dryer, which corresponds exactly to the requirements of prEN ISO 6330, Marks and Spencer P1A and AATCC 135.

Accudry is engineered for laboratory shrinkage tests. It is designed to reduce machine variables and operator error to the absolute minimum.

The Dryer is equipped with a digital, exhaust air temperature controller and digital timers for the heating and cooling periods. A mutable buzzer signals the completion of the timed cycle, but Accudry can also assist laboratory technicians to establish the optimum duration of heating and cooling cycles. Mass-produced domestic tumble dryers give no indication when their loads have reached the required state of dryness, whereas Accudry’s digital display of actual temperature makes it possible to determine when moisture vaporation is completed.
