Mechanical structure:

1.STIK three-axis off-center actuating structure has undergone strict mathematic analysis,and is a high-performance product proven by long-term stability operation which adopts axletrees with best abrasion resistance and maintenance-free,long service time ,brushless actuating sysem with unidirectional flow,its base frame adopts vermicular casting technique which has the best stability .Advanced numerically controlled processing technique ensures high reliability and stability for the mechanical structure itself. Scientific off-center weight balancing data ensures long service time for the three-axis off-center actuating machine itelf.

2.STIL three-axis off-center actuating structure ensures stable start-up and half of the samples.NO sudden dithering during operation which prevent cells sensitive to shearing force from dying or being harmed.

3.The error for mechanical processing of the machine is less than 0.**5mm, and the general rigging error is less than 0.*2mm of deviation ,which ensures long service time,stability and non-vibration for the machine.

Operating system:

1.Advanced fuzzy logic PID conreolling system provides rotation speed, tenperature control for product, and operating time.

2.Membrane touching keys are adopted in an operating sysem which also has large –scale liquid crystal display ,RS**2 interface reserved, optional communication software.

3.Standard mode and program mode for operating system ,the former one can be configured through menu with fixed temperature,rotation speed and time.Temperature,rotation speed and time can be configured as required by the users under program mode, which also has timed shutdown function.

4.Top and bottom temperature configuring limit alarm for temperature control system with independent mechanical overtemperature protection device.

Air duct structure:

An unique air duct structure with top duct for intake and bottom duct for return,high-quality axial flow fan,condenser and evaporator that transfer heat rapidly,together they ensure homogeneity and precision of temperature.

Cooling system:

Use environmental R**4a cryogen, designed to contain overvoltage crowbar circuit and voltage relief circuit and has automatic defrosting function.
