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. For larger doors, heavy duty door frame is available to support the weight of the sliding door. Automatic and electric doors can be ordered as option for heavy traffic cold rooms.

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.

Pressure relief port In freezer where operating temperature is below freezing, it is recommended to install pressure relief port to equalize the pressure, especially during door opening and defrost cycle. KOLDTECH can recommend the number of ports required based on the operating temperature and the room volume.

KOLDTECH REFRIGERATION SYSTEM. Koldtech coldroom system has been throughly field tested. It has been improved upon based feedback from technicians and customer. Our stringent QC department, using sophisticated testing equipments assure that the system will work well according to specification. With reasonable care, the system will give you years of trouble free service. Koldtech system offers wide range of coldroom system for your different operating requirements. We offer both Hermetic and Semi hermetic systems, operating on non-CFC or R-22 refrigerant. The unit is available with both air cooled and water cooled. Marine upgrade is available to minimize effect from salt for seaside installation. The system requires three phase 50 Hertz power supply, with 60 Hertz voltage as option available. KOLDTECH refrigeration system is also equipped with phase detector to protect it from fluctuation voltage supply. There are many other built-in safety functions to assure that our system is well protected from unstable power supply. Delay circuit is built-in to delay the compressor start up after a shut down.

Condensing units can be installed remotely. Standard length is not more than 20 m. from the evaporator unit. For distance longer than 20 m. we may need to increase the pipe size or increase the compressor capacity. Multiple compressors can be connected together in a rack system, providing more efficiency and system back up.

Standard Coldroom Floor

FINISHING PROFILES

KOLDTECH offers different configurations for coldroom floor. We can design or give recommendation for your specific application. Slip guard patterned aluminum checker plate is recommended for most cold room application where only foot traffic presents. Aluminum checkered plate floor is composed of polyurethane floor panel with GI steel sheet finish topped with 1.5 mm aluminum checker plate. In application where trolleys are used, a 6 mm. FLEXY BOARD is installed below the metal skin for reinforcement. Maximum weight permit is 500 Kgs on four rubberized wheels. While the maximum stationary load for KOLDTECH coldroom floor is 3,000 kgs./sq. m. (614 lbs./sq. ft.).

Concrete floor Coldroom where mechanical devices e.g. hand truck or forklift are used, concrete floor is recommended. Bare polyurethane insulation is installed on the existing floor, followed with polyethylene sheet as a moisture barrier, then 100 mm. of reinforced concrete. Top surface can be tiled, epoxy or any other material, depending on requirement. The figure shows different types of installation of coldroom floor. In many cases, where the level of the coldroom floor is not the same as outside, a ramp is available as an option to provide easy access to the coldroom.

The above table is calculated based on ambient temperature of 36 degree Celsius, and room temperature for chiller of 0 degree Celsius and freezer room temperature of -20 degree Celsius. Condensing units can be installed remotely. Standard length is not more than 20 m from the evaporator unit. For distance longer than 20 m. we may need to increase the pipe size or increase the compressor capacity. Multiple compressors can be connected together in a rack system, providing more efficiency and system back up. Many options are available for example remote monitoring and controlling system, where all systems can be monitored, controlled and diagnosed remotely from the control room or from another part of the world through internet connection. For custom design of coldroom and system, please contact us for design and quotation upon request. With years of experience in this field, we can provide you with professional proposal and recommendation for years of trouble free operation.
