Cold Room Panel

Image
Square Panel System Co., Ltd. have been manufacturing cold room sandwich panel by using non-CFC polyurethane foam (PUF) as insulating core material which is non harmful to world environment. The panel offers several advantages over traditional polystyrene foam including great thermal resistance and increased efficiency. This means lower energy consumption for refrigeration unit. All parts are supplied in knock down condition.

Light weight

The Panels are made of rigid polyurethane foam (PUF)  foamed in place as core material in between colored steel sheet (Thickness 0.45 mm. BMT) giving high strength to weight ratio and reducing structure requirement for building

Door with safety device available

Door latch is designed with an inside safety release feature that guarantees immediate release from inside the cold storage room in case of emergency even though the door is locked on the outside.

Durable, corrosion protected surface

Finished surface of panels is double paint coating on galvanized steel sheet. The panels can resist corrosion even wet, high moisture working environment. Off white is normal standard color. Other colors and materials are also available upon special application for instance 304 stainless steel

No Condensation at joint

All panel joints of wall, ceiling and floor shall be specially designed tongue – in – groove sleeve. This sleeve joint is fully aligned precision – made panel connection system, allowing virtually 100% insulation to insulation contact, leaving no gaps in between in order to avoid condensation. The sleeve shall be secured with engineering plastic locking cam so-called CAMLOCK. CAMLOCK shall consist of a cam action hook locking arm placed in one panel and a pin precisely positioned in the adjoining panel, so that by rotating the locking arm, the hook shall engage over the pin and with cam action, draws the panel tightly together

Easier and less installation time

All parts are factory prefabricated in knock down condition and ready to assemble at site therefore reduces installation time significantly.
