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.
