PVC Fabric Cold Room Door

Cold storage fold up doors are designed to meet expectation of clients for high level insulation for areas like freezer / chiller rooms & Cold storages.
Mainly losing of energy is occurred during door operations. Conventional sliding cold room doors are slow in operational speed, obstructs the forklift
traffic resulting high energy consumptions.
Cold storage door with high speed operation and specially designed for maintaining ambient environment between chilled and freezer area.

Parameter


Frame Structure

The frame is constructed using high-grade straight extruded aluminum alloy (6063-T6 alloy) with bolt fastening; only the top cover is made of
galvanized steel plate. All side guide grooves and base frames are manufactured without welding processes, eliminating gaps and corrosion issues.
For special usage areas, the main structure can be fabricated from AISI 304/306 stainless steel or standard steel.

Insulation Performance

This door is specially designed to eliminate thermal bridging effects and achieve optimal thermal insulation. Our patented structure effectively
reduces the heat transfer coefficient.Shade thermal insulation performance: U-value = 0.70 W/m²·K (according to BS EN ISO 6946 standard)
Sound insulation: 14 dB A

 

 

Fabric

This fabric has a long service life and excellent resistance to ultraviolet radiation.
VALMEX POLYMAR® Industrial flame-retardant fabric, weight 900 grams/square meter, thickness 1-2 millimeters, 1100 denier, B 6000
Panama plain weave, SIO‑LINE series; compliant with DIN EN ISO 2286‑2 standard, CE certified.
Longitudinal / Transverse Tensile Strength: 4300 / 4000 N / 50 mm (according to DIN 53354 standard).
Tear strength: 500/500 N (according to DIN 53363 standard).

 

 

Colour

Wide range of fabric colours are available like RAL 9002-9006-1001 -3001 – 5007-6001-7071.

*Some color is out of stock can be extend delivering time.

 

 

Isolation Material

 

Extruded polystyrene foam (XPS) is a closed cell structure with better surface roughness, higher stiffness and lower thermal conductivity.
The density range is about 28-45 kilograms per cubic meter. The thermal conductivity ranges from 0.029 to 0.039 watts per meter Kelvin,
depending on the compressive strength/density, with an average value of approximately 0.035 watts per meter Kelvin.The thickness of the
curtain is 40 millimeters, and the overall heat transfer coefficient (U value) is less than 1.5 watts per square meter in Kelvin;
Sound insulation level of 18 decibels (weighted by A). Aluminum alloy side rails are equipped with rubber sealing strips to further enhance

sealing and
insulation performance.

 

Motor and Gearbox

 

Motor power: 1 horsepower to 4 horsepower; The working voltage is 380-440 volts three-phase, 50-60 hertz, and the specific
configuration depends on the size of the door body.Continuous industrial operation requires three-phase power supply.
The reducer adopts a high torque dedicated worm gear structure reducer.All product materials are manufactured in accordance
with CE standards.
