Novas
Hydraulic doorclosers are used to suit various
residential and commercial applications.
By definition, door closers are used to
close hinged leaf doors after they have
been manually opened. The smooth closing
operation is controlled by the adjustable
hydraulic rack and pinion mechanism.
In choosing a closer style for a particular
application consideration should be given
to the type of door being controlled, frame
condition, aesthetic and the control features
required by the end user.
The size and weight of the door is the main
consideration in selecting a closer of the
correct strength. Recommended door widths
for each closer assume normal operating
conditions. If a door is of exceptional
height, weight, special construction, or
if air pressure differentials exist, a higher
power closer should be considered.
A door closer effectively increases the
loading on door hinges and their rate of
wear. It is recommended that any door fitted
with a door closer should use three or more
Novas Ball Bearing/Sintered Bearing Hinges.
It is essential that the door be clear in
the doorframe and when fitted with a lock
the latch bolt must engage freely with the
strike.
Floor or wall mounted doorstops should be
fitted to prevent possible damage to the
door frame and fitted hardware. |
