Eccentric lock Eccentric lock is custom designed and manufactured to our specification. It is made from high impact ABS plastic with rust resistance GI steel. During the foamed-in-place process, the locks are embedded every 800 mm. for the flat wall panels and every 400 mm. for corner joints panels. During the installation, a hexagon Allen key is used to latch the male and female eccentric locks together. The locking action is in two steps, firstly to latch the locks and secondly pulling the panels together to form a tight seal, preventing cold air to escape from the cold room. After the latching process a flush PVC cap is used to close the hexagon key access hole.
Modular panels KOLDTECH panels are produced with the foamed-in-place process, where two chemicals are injected under pressure between two metal skins to form Polyurethane insulation panels. Chemical reaction produces high heat and high pressure during curing. Pressure of over 500 tons is applied to the panel resulting in high structural strength, high density and thus high insulation value of the Polyurethane panel. KOLDTECH panels come in standard size but can be custom designed to fit your available space and your requirements. Panels are manufactured in sections and assembled at work site like putting together pieces of puzzle. Panel width is 400 to 1200 mm, with length of 400 to 7000 mm. Ceiling, wall and floor are latched together using eccentric locks. Tongue and groove with Polyethylene gasket joint ensures that the installation is completely air tight. Butt joints panels are available on request. Metal Finish and thickness KOLDTECH panels are available with many types of metal finish to suit your job requirement, ranging from stainless steel, Colorbond steel, Galvanized steel, Zincalume steel and Stucco aluminum. Metal finish is grooved every 5 inches to increase the structural strength and improve the look. Each panel is coated with scratch proof PVC film which protects panels finish during transportation and installation. The film can be peeled off after installation. Polyurethane panel thickness is available from 60 mm to 150 mm. Table below shows KOLDTECH panel thickness with corresponding specification. KOLDTECH polyurethane panels are injected with blowing agent with low ODP (comply with Montreal Convention) and exceed UL 94 fire retardant standard. We regularly monitor and test our product, by independent laboratory, to ascertain that it meets our high standard. Koldtech Panel Specification Thickness

Gasket tongue To further seal off any irregularity of the panel surfaces, the closed cell polyethylene foam gasket or gasket tongue is used. It is installed on the edge of the panel during the foaming process. The gasket is compressed to form a tight seal without the need of sealant. Door KOLDTECH hinged door is integrated into our standard wall panel. Our standard door size is 900 x 1900 mm. and 1000 x 2000 mm. The door comes complete with a door latch, a keyed cylinder lock, a safety door release from inside, self closing mechanism, hydraulic door closer. The spring action integrated into the door hinge closes the door by itself if it is left open less than 90 degree. The hydraulic door closure latches the door tightly to prevent any cold air leakage.
Water proof light switch with vapor proof interior light is included. Door finish and Polyurethane insulation thickness are the same material and thickness used for the wall panel. Heater wire is installed in the door frame to prevent condensation. For Freezer room, easily replaceable heater wire is also embedded into the door leaf. Other options available are viewing windows, kick plate, door ramp. The figure above shows different components and accessories for KOLDTECH hinged doors. Sliding door is also available. KOLDTECH doors use heavy duty hardware which has been field tested and improved upon. Different models are available depending on applications.

Ceiling support is necessary for ceiling panels over the length of 3 m., to prevent any sagging due to the weight of the ceiling panels. Ceiling panels can be suspended from existing building structure by means of wire or wire sling. In case the suspension from existing building structure is not suitable, a self support system can be employed. KOLDTECH offers several types of ceiling support as follows:
Metal plate A small GI steel plate is sandwiched between the ceiling panel eccentric locks and attached to the supporting wires. The supporting wire is, in turn, attached to the building structure and transfer part of the ceiling panel weight to the building structure.
