Available from Hillaldam Coburn, the Evolution is designed to provide a suitable solution for automatic door closers to comply with the Disability Discrimination Act. Measuring 545mm long with a cross section of 110 by 120mm, the product is compact and incorporates functions normally installed separately. It acts as a conventional door closer for the able bodied but also provides automatic button operation for wheelchair users or those that require mechanical assistance. Featuring a built in encoder, it does not necessitate separate safety systems, and has anti-crush protection based on an intelligent sensor. The opening time is variable between one and 20 seconds.
