Low Temperature High Speed Roll Up Freezer Door Frost Resistance
Insulation- Product overviewOur cold storage thermal insulation
zipper door is a thermal insulation and energy-saving internal fast
door in the cold chain logistics area, which helps to save energy,
reduce air convection and reduce noise. The heating and antifreeze
device of the cold storage door can ensure that the product runs
smoothly and effectively in a low-temperature working
environement.- Product advantagesDoor curtain: The door curtain
comes with a thermal insulation PU foram layer, the total thickness
is 3mm, the curtain blank, the total thickness after processing is
about 14mm.Sealing performance: The structual design and
application of the top and bottom seals of the door body can
effectively isolate the air pressure convection on both sides of
the door body, and further strengthen the air tightness.Wind
resistance strength: The curtain guide components, curtains and
guide rails in the door operation guide system are closely matched,
and the material has strong wear resistance, which ensures the
overall wind resistance. It can reach the national standard wind
resistance level 8.Heating antifreeze device: The design and
application of the heating mechanism avoid the freezing of the
guide rail caused by the heat exchange caused by the frequenct
operation of the door, and further ensure the stable operation and
working efficiency of the door in a low temperature environment, At
the same time, the box removal equipment can be optionally
installed as needed to double guarantee the working performance of
the product in a low temperature, and the working temperature is
-1°C to -28°C.Operating speed: Opening speed - the maximum opening
speed is 0.6-1.2m/s, adjustableClosing speed: The closing speed is
not less than 0.6m/s, adjustable. Track: The track is made of
polymer materials, and the frame is made of stainless steel 304.-
Product accessoriesMan-machine dialogue interface: It can realize a
complete and systematic dialogue effect to minimize the maintenance
labor cost and efficiency after acceptance and after the warranty
period. The daily synchronous display of "door opening", "working
time" "run time" and various running codesFast door power failure
menory function: When the power is off, the swtich position of the
fast door can be manually operated at will, and it can work
directly without adjusting the limit after power onSteering setting
and identification function: When the phase sequence of the 380V
power input or the phase sequence from the control box to the motor
is connected incorrectly, the system directly reports an error,
which effectively avoids major safety accidents caused by neligence
in the later period of self-maitenance or relocationEffective
operating position setting and recognition function: When the fast
door limit is set, the control system can intelligently identify
whether the door is moving in an illegal range. Once the system
recognizes, it will promot "limit abnormal" and stop request
continue to work after overhaul, this function is mainly aimed at
the later brake system failurePermanenet and no cumulative error:
The encoder accumulates the most common and common fault problem of
fast doors at present, and the full-scale adbolute value limit
technology completely avoids thisFull-range absolute value limit
technology: Multi-turn absolute value encoder is the main
supporting hardware for the whole range limit technology. It is a
traditional incremental encoder (using pluse counting to simulate
the stop position) and a single-turn absolute value encoder. The
upgraded version of (using the program to count the number of
turns) is equivalent to adding the number of turns of the gear set
on the basis of the traditionally applied encoder, so that each
position signal from the encoder to the controller is independent,
based on multi-turn adsolute characteristics of value
encoder.Position closed-lopp frequency modulation technology:
Mainly refers to the random change of the running speed of the fast
door, and there is no need to re-calibrate the limit after
adjustment.Professional drive circuit board hardware: The
traditional control system using common PLC and frequency converter
and incremental encoder on the markey has many inherent limitatios
in the fast door technology, which cannot be perfect: such as
various safety protections. The response time of the swtich is the
cumulative error of the incremental encoder, the connection problem
between the multi-turn adsolute encoder and the PLC, and the
non-professionals cannot repair it. Shortcut function of itinerary
