Normal time temp. maintaining at -90 degree C with 2comp. and when Emergency single comp. maintaining at -80 degee C <>>.  

It is a REVOLUTION on the COOLING TECHNOLOGIES !!.  

No need Welding work when compressor replacement

No need shift samples to other backup freezer when emergency

No need switch-off when compressor replacement

No need charging or discharging when compressor replacement

No need special service tools like welding machine,torch,gases, etc..,, spanner is sufficient.

No need specially trained service engineer, Users can replace the compressor within 30minutes
