Q2.Can I have a sample order?
A:Sure, every item in our company has sample.

Q3.What's the MOQ?
A:We accept 1 piece order and 10000+ pieces order, The different between them only in price.

Q4.Whether to accept custom or not?
A:We accept OME and ODM,Even OBM is ok.

Q5.What's Free Piston Stirling Cooler?
A:FPSC (Free Piston Stirling Cooler) is a new type of completely cfc-free, high efficiency, energy saving and environmental protection Cooler, which uses a small amount of helium as the coolant.
The brief mechanism is that the cylinder (fin) protruding from the main body is cooled by heat exchange, which is a process of repeated cycle of compression, and the stainless steel piston in the main body is constantly moving up and down, resulting in gas explosion.

Q6:What's the advantages of Free Piston Stirling Cooler?
A:
1.Oil-Free, Ultra Quiet, Vibration-Free
2.Smallest & Lightest, 2.0kgs (only 1/5 weight of normal compressor)
3.For liquid freezing application, 30% at least energy savings
4.For air cooled application, 50% at least energy savings
5.MagLev technology better reduce system redundancy
6.Ultra compact
7.Light weight
8.Portable
9.Efficient
