Performance Parameters
Both the interior and exterior are made of robust materials for lifetime operations. The inner
chamber is made of high quality #304 stainless steel sheets, with 4 round coved corners. All
exposed edges are de-burred to insure no sharp edges. The exterior is cold rolled steel finished
with powder coated polyurethane finish, which is resistant to most chemicals and easily cleaned
with mild household detergents.
The ZHICHENG shaking incubator
’s microprocessor control system uses fast responding PT 100
sensors which commands and executes a special control algorithm that energizes a solid-state
switch to supply power to the heaters.
The control electronics are protected trough a circuit breaker that may trip at 110% of loading rate,
but will trip within 1 second at 150% of load rating.
The compressor (in refrigerated units only) has an independent overload protection.
CFC-free refrigerant which causes no damage to ozone layer.(Applies on ZWY-2/ZWF-2 models)
Large doublefold tempered glass window and flourecent light, provide complete visibility of
chamber interior.
Models ZWY-111D and ZWY-211D are equipped with foot pedal for lid opening even when
carrying full loads in both hands.
LCD display presents all actual and (pre)set parameters.
Electronic timer, from 0
– 9999 Mins, automatic stop, audio/ visual alarm.
Password protection against unauthorized change of parameters.
Audible and visual alarms for motor temperature and set point deviations
Non-violate memory for set point retention after a power interruption.
“Long-Life” brushless AC motor creates a smooth, quiet and uniformed shaking motion
High capacity for up to 5L flasks (except ZWY-111B/211B, ZWF-111/211)
Option: unit equipped with RS-485 interface communication can be connected to local network so
that remote data logging and control can be achieved via laptop/ PCs.
