YKA type round hole type graphite heat exchanger　
　
　　Round-block and holestyle graphite heat exchanger series is now the most advanced products with the great capacity.Cylindrical heat exchangers unit made of standard unit have high-strengthen structure inwhich designed F4O shaped sealed medium in stead of cementation agents its excellent improvement is auto-complement device equiped pressure spring for extending and shrinking，shorten-tube,extraredistribution for increasing function.So that have gained the following particularly features like: high-strenght structure,stronge resistance to high temperature and pressure, resistance to struck efficient size usage,efficient heat-transfer function, long life span and Easy checking and repairing. This series could used as evaporator，heater, cooler.Please note that it needs to install gas and liqiud at bottom as cooler.
