1.Absorbing film
Black Chrome film most economical
Blue Titanium film-stitched more cost than black chrome film
Blue Titanium film-complete more cost than Blue Titanium film-stitched
2.Aluminum alloy frame
Optional thicknesses are available with 0.85mm 1.0mm.
0.85mm is cheaper but easier to bend!
Optional colors are available with Silver, Golden and Black
3.Weld
If laser weld
easier and faster for production
poor heat conduction due to small heat production area by laser weld
short lifespan due to different expansion coefficients between copper tube and aluminum film, weld breaks after long time use
obvious wrinkles
If Ultrasonic Wrap Welding
big tolerance on copper pipe thickness, because there is no weld on copper pipe
poor heat conduction due to gap between film and copper pipe, but higher efficiency than laser weld
no wrinkles
If Ultrasonic welding
professional and mature skills
high efficiency of heat conduct efficiency
long life span
no wrinkle
direct weld on film needs high quality film and copper pipe thickness >0.5mm
4.Frame installation
If Bends and Rivets
Light and easier to form shape, low cost
Weak and easier to break
Not beautiful using rivets to fix back board
If Corner fixer pressing no rivets
Strong
More costly
5.Sealing material
glass glue - low cost but low sealing performance
EPDM strip - higher cost, more difficult to assembly, durable and high sealing performance
6.Insulation wool
If Black polyester cotton
easy operation for workers
poor thermal insulation performance, easy to fog
If Glass fiber cotton with aluminum foil reflective film
good thermal insulation performance
high heat utilization efficiency
not easy to fog
irritate the skin
workers must wear protective clothing when operating
7.Air vent
If Rubber cap
low cost, easy assembly
poor exhaust performance
If Special nylon exhaust cap
good exhaust performance
high cost, more difficult to assembly
8.back board
Ziinc coated steel - low antirust peroformance , no painting protection
Galvanized steel - higher antirust performance, zinc layer and painting double protection
Aluminium steel - best antirust performance, easier to dent
9.Inlet Outlet
With or without male screws, cost is different
10.Package
With moisture-proof film
Optional half packing at 2 ends or 100% packing
