Sprint 300 Plus Improves Quality Of Clean Rooms

Sara Loading Bay Specialists has introduced the Sprint 300 Plus clean room door, which enables pharmaceutical and food companies to improve the quality of clean rooms. The high-speed and flexible configuration of the Sprint 300 Plus - with optional FDA-approved materials - means that it is suitable for areas where there is an air-pressure difference, such as clean rooms. In these environments, the Sprint 300 Plus also saves energy and provides maximum safety provision, with an electrically monitored contact safety beam and a clear safety curtain that allows personnel to see movement on either side, which is essential in facilities that employ automated transport.

Designed to conform to EN 12424, Class 1, for wind resistance, the Sprint 300 Plus is described as a robust, flexible and highly reliable door that provides smooth and steady movement via a curtain tensioning system. It can be programmed to meet specific customer needs using Sara's optional MCC Vector control system. The flexibility of Sprint specification allows the door to suit widths from 1,000mm to 4,000mm and heights from 1,000mm to 4,200mm and delivers a space-saving design that is said to be suitable for areas with restricted head room.

The Sprint 300 Plus offers users the choice of galvanised- or stainless-steel side frames, barrel and motor covers, with bottom rails of anodised aluminium or stainless steel. This choice also extends to materials for the door curtains. The standard is clear PVC with coloured reinforcing stripes, with the options of: PVC with silicon-free reinforcing stripes; Rolltex (with optional windows), which has a sound-reduction quality (Rolltex Plus Fine reduces sound by approximately 17dB); and FDA-approved Nomatex, which is available in yellow and grey with optional vision panels and in a flame-retardant configuration for increased safety applications.

The Sprint 300 Plus door saves energy because of its high-speed operation, with opening speeds of up to 2.2m/s provided from the optional vector control system. It can also be programmed for dual opening heights with the vector control option reduced for normal use - keeping energy losses to a minimum - and full-height opening for occasional larger equipment. The door is equipped with an electrically monitored contact safety edge and integrates a door line stationary photo cell, which automatically stops the door if it senses an obstruction and returns it to its open position.

In addition, drop-down protection is provided by tension springs and there is a built-in facility for emergency self-opening in the event of power failure; this via a Bowden lever brake release. Complementing the range of standard safety features are a number of options. These include: an automatic self-opening feature; the facility for a second Bowden lever brake release; integrated light curtains for doors of more 1,865mm in height; and a knock-out facility option for impact protection with manual reset.
