Istanbul, Turkey – Turkish systems house, Kimteks will give details of its new high flow system for pentane-blown refrigerator foams at UTECH Europe in Maastricht later this month.
UTECH 2018: Kimteks outlines new refrigeration system
The materials are called Kimcool. 'A number of leading home appliance producers in Turkey,' are using the systems said the firm. The refrigerator firms chose the materials because of their low viscosity. This means that it is possible to achieve good fill without voids and to make refrigerators with smooth surfaces, the firm said.
The systems feature a catalyst package that enables cycle times to fall from around 220 sec/refrigerator to around 180 sec/refrigerator, said the firm.
It added that polyols used in the systems are compatible both with cyclo- and iso-pentane.
Cyclopentane 70 and cyclopentane 95 are compatible with the systems, Kimtecks said.
Cyclopentane 95 formulations typically produce foam with thermal conductivity of about 20.5 mW/mK at 24 C.
Closed cells account for 95% of the finished foams, which also have a high cross link density, the firm added. This helps foams produced with the system to retain dimensional stability at high and low temperatures, the company added.
Kimteks said it has capacity for 27 kT/year polyester polyols, 30 kT/year isocyanate prepolymers and 106 kT/year formulated polyols. Kimteks recently expanded production in Gezbe in the west of Turkey and an office in Gaziantep in south eastern Anatolia.
UTECH Europe will be held in Maastricht from 29-31 May 2018.
