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


Structure

Structure is made from high straight extruded Aluminum (Alloy 6063-T6) fixed with bolt & only top cover is made by galvanised steel sheets. All side guides and bottom frames are manufactured to avoid welding, gap and rust. Stainless Steel AISI (304/306) or normal steel structure can be manufactu-red for special area.

Insulation Data

We specially design the door to avoid heat bridge and maximum isolations. Our patent pending design especially decreases thermal transmittance. Cur- tain Thermal insulation: U = 0.70 W/sq-mt.K (BS EN ISO 6946) ˜ Sound atte-nuation: 14 dB A

 

Fabric

Fabric has long life and it has very high resistance against UV radiation, VALMEX POLYMAR ® Industrial  Fire resist 900 gr/m2  1-2 mm 1100 Dtx B 6000 Panama SIO  – LINE + DIN EN ISO 2286 – 2 –CE. Tensile Straight 4300/4000 N/50 mm DIN 53354.  Tear Strength 500/500 N DIN 53363

 

 

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) consists of closed cells, offers improved surface roughness and higher stiffness and reduced thermal conductivity. The density range is about 28–45  kg/m3. Thermal  conductivity  varies between 0.029 and 0.039 W/ (m·K) depending on bearing strength/density and the average value is ~0.035 W/ (m·K).
Curtain thickness 40 mm U value (overall heat transfer co-efficient’) <1.5 W/m2.K Sound attenuation 18 dB A. Aluminum side rail has rubber sealant for extra isolation.

 

Motor and Gearbox

 

Motor power from 1HP upto 4HP, Operations voltage 380-440 V 3phase  50-60 Hz depending upon dimensions of the doors. 3 Phase operation volta-ge is required for continuous industrial operations. Gearbox is chosen for special high torque worm hole design gearbox. All materials are manufactu-red according to CE norm.
