SPECIFICATION
Cold Saver® 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 Saver® door with high speed operation and specially designed for maintaining ambient environment between chilled and freezer area.
24 x 7 Operations
Strong and flexible design of Cold Saver® high speed door can be operated 24 x 7 specially chosen high resistance fabric and gearbox system are desig-ned for continuous operation.
Excellent Sealing
Special designed curtain is filled with high density polystyrene materials (U value ~0.035 W/ (m·K).) Curtain reflects the heat radiations from surface, and hence Cold Saver doors can be utilized from -1 oC down to -30oC. Side guide has isolation rubber and guide is designed to avoid Heat Bridge. Cold saver® has soft edge system specially made from pot to increase isolation.
Save Money and Time
Cold Saver® doors reduce energy consumptions more then 20% for air con-ditioned area. System regulated forklift traffic also save time during operation.
Low Maintenance
Cold Saver ® doors doesn’t require any special maintenance.
Applications
For industries that require isolation, flexibility, performance, uptime and high traffic areas roll up door is a feasible solution.
Maximum Dimensions
Cold Saver ® doors can be manufactured up to 4500mm W X 4500mm H for internal or external applications. For High wind resistance isolated fold up Door are available.
* Comparison is made between conventional Manuel sliding cold room doors at high traffic conditions.
TECHNICAL PROPERTIES
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.
Interior Heating System
Fire Resistance
Fire resistance of the fabric is suitable for any fire safety regulations. Relati-ve Standard is DIN 4102-B1. These materials are tough to ignite. They inclu-de materials such as wood treated with a fire retardant and rigid foam plas-tics. A fire must extinguish itself when the source of the fire is removed. Isolation materials between fabrics-XPS- has weakness against to fire “igni-tion barrier” in accordance with section R314.
Speed
Cold Saver High Speed Doors can be operated at a standard 1.2 mt /sec (EN 12453) and speed range can be designed upto 150 cm/sec.
Equipment
Safety photo cell beam, thermic resistance, soft bottom edge, emergency button warning light and buzzer is supplied Standard equipment Optionally Bottom safety edge and pneumatic safety edge internal heater system is available.
Safety
All the doors are manufactured according to CE Standard- Industrial, com-mercial
Product standard - Applicable Directives 89/106/EC-99/93/E
Appli-cable Standards: - EN13241-1:2003+A1:2011-EN 12978:2008.
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.
Control board
Control board is designed according to CE 2006/95 EC and NEMA ICS 2 Stan-dard to operate 3 phase motor with rotative swicth. Audible and visual war-ning devices automatically signal for 5 seconds before any door section mo-vement, remain continuously on while the door is in motion and reset imme-diately after movement stops. IP 65 Box Emergency button Circuit Breakers Warning light Buzzer, Plug in technology.
Options
- Frequency converters control board with touch less button
- Mono phase operators.
Operations
Speedd Flex® fabric door is guided up and down in the weather sealing ver-tical guides attached to structure. Door is controlled by three buttons marked "Open", "Close", and "Stop". It is controlled by momentary pressure to open and constant pressure to close. (Reverse is available) it can be opera-ted with Radar, Remote controller, Metallic Loop Detectors, Pull rope switch as an options.
Loop detectors;
Together with inductive loops laid beneath the surface, LC series loop detec-tors form a universal sensor system for detecting vehicles and forklift. Human traffic is not detectable with loop detectors.
Infrared Radar;
Opening impulse sensor for automatic doors and industrial doors i Motion sensor for people and objects.
Remote Controller;
Is a component of an electronic device to operate the device with radio frequency from a long distance (25 mt up to 100 mt)
Manual Operations;
In Emergency situations or power is of Doors can be operated manually with standard hand crank attached to output shaft of motor.
