Metaflex doors<br />
Mechanical engineering expertise, advanced<br />
insulation technology and skilled workmanship<br />
are embodied in all Metaflex doors.<br />
Applications<br />
Metaflex doors meet the highest quality<br />
requirements and provide the ultimate solution<br />
for cold storage, food processing areas, the chemical<br />
industry and many situations with a controlled<br />
environment.<br />
Standard design <strong>MF</strong>7 - <strong>Polaris</strong><br />
The doorblade is constructed from a series of<br />
insulation panels faced with either white (RAL 9002)<br />
coated or stainless steel sheet and framed with<br />
heavy gauge aluminium or 2 mm stainless steel<br />
profile.<br />
Panel system<br />
The <strong>MF</strong>7 panels, either 80 mm or 120 mm thick,<br />
have a core of pressure injected polyurethane<br />
insulation with a density of 45 kg/m 3 .<br />
The Metaflex rail system is a combination of aluminium track and two hard wearing nylon rollers. Special indentations in the track allow<br />
the door to slide down and in at an angle of 45° utilising the weight of the door to give a perfect seal when closed.
Contruction<br />
Many years of research have led to the design of<br />
an advanced rail system with the minimum of just<br />
two moving parts which allow the door to seal under<br />
its own wieght by sliding down and in at an angle of<br />
45° against the frame and threshhold. Combine the<br />
unique rail system, high insulation properties of the<br />
polyurethane panels, effective sealing gaskets and<br />
you have the perfect chiller/freezer door; energy<br />
saving, totally reliable and easy to use.<br />
Durability<br />
The door has been designed to withstand the rigours<br />
of industrial use. The composite panel construction<br />
is extremely stable and is contained in a heavy duty<br />
framework and this, together with a horizontal<br />
bumper bar, protects the panels from impact<br />
damage and gives rigidity<br />
Temperature<br />
Depending on ambient temperature the doors are<br />
designed for cold rooms operating from as low as<br />
-25°C to +70°C. If doors are for freezer rooms<br />
then a self regulating heater tape is fitted to prevent<br />
the gasket from sticking to the frame.<br />
Finish<br />
The Metaflex doors are available in coated steel sheet in a<br />
chaice of RAL colours or in stainless steel with a circleground<br />
pattern.<br />
Manual or Automatic<br />
All Metaflex doors can be manually operated or<br />
fully automatic with a microprocessor controlled<br />
electric system. It is recommended that doors<br />
which are used extensively are automated with<br />
resultant savings of energy and operator time.<br />
Electric automation<br />
This consists of a 220/380 V motor mounted on<br />
the rail system which fully drives the door open<br />
and closed. A safety strip on the leading edge will<br />
re-open the door if an obstruction is encountered.<br />
The door can easily be operated manually in the<br />
event of power failure.<br />
Controls<br />
The standard operation is by means of push<br />
button/pull cord switches.<br />
Infra-red or radar detection units can be added<br />
with timer close facility.

Specification <strong>MF</strong>7-POLARIS<br />
Rail system<br />
The doorblade is suspended by two specially formed<br />
brackets fitted with hard nylon rollers which run a<br />
heavy gauge aluminium track. The brackets allow<br />
easy adjustment so the door may be accurately<br />
aligned. A canopy is provided to cover the full length<br />
of the track in either coated or stainless steel sheet.<br />
Manual operation is by means of lever handles with<br />
locking (optional).<br />
Doorblade<br />
The doorblade is built up from a series of easily<br />
interchangeable insulation panels which are framed<br />
in either a heavy gauge aluminium or 2 mm stainless<br />
steel profiles. The surfaces are protected with a vinyl<br />
film which should be removed after installation.<br />
Door frame<br />
Various door frames can be offered to suit<br />
the wall construction. The standard frame is<br />
45 mm x 150 mm and can be manufactured in<br />
either coated or stainless steel sheet infilled with<br />
polyurethane insulation. Alternatively ‘U’ profiles<br />
can be specially formed to suit the insulation panels<br />
or wall thickness. For low temperature applications<br />
a self regulating 220 V or 42 V heater cable is<br />
incorporated in the frame.<br />
