Product Description
Description:
There must be residual gas existing in high vacuum environment where the oil diffusion pump
is used, and more than 80% is water vapor, oil vapour and other high-boiling oil vapor steam.
But pumping gas is difficult and time-spent and the residual gas will pollute the workpiece,
so the yield and quality of products will be influenced. Ultra-Low temperature freezer can
solve all these problems.
The working principle of direct-cooled ultra-low temperature freezer is placing a cooling coil up
which cooling to -120℃ at a vacuum chamber or pump entrance. Through condensation effects,
rapidly collect the residual gas in the vacuum system, thus greatly shortening the vacuum time
(can reduce 60% to 90% of the extraction time), to obtain a clean vacuum environment.
Our company developed the production of -135℃direct-cooled ultra-low temperature freezer,
using a single compressor, auto cascade refrigeration mode, DORIN compressors
and refrigeration parts, environmental mixed refrigerant production. With specific cooling speed,
high efficiency, low temperature, easy maintenance and other specific, rapid cooling, the
temperature can be cooled to -120 ℃ within three minutes, the minimum temperature is -150℃
FEATURES:
♦ Temperature ranges from - 5 ~ - 150 degrees, can meet different
temperature
♦ Adopt environmental protection refrigerants
♦ Famous brand semi-closed piston compressor, semi-closed bipolar
piston compressor, semi-hermetic screw compressor, main brand are
BOCK. Bitzer, Copeland, Hanbell, fusheng; Plate heat exchanger, Small
volume, High efficiency
♦ Top imported cold controller(DANFOSS pressure controller, balance
valve, expansion valve, solenoid valve, filter drier, Emerson oil separator,
ALCO liquid mirror, check valve, etc.)
♦ Generator cooling water circuit use intermediate heat exchanger,
improve system reliability and safety
♦ DANFOSS electronic expansion valve, high precision control;
♦ Adopt Siemens PLC S7-200/300, LNEYA touch screen, automatic control,
temperature curve display, temperature record U disk, fault alarm;
♦ Large cooling capacity adopts semi-hermetic screw compressor,
electronic expansion valve control, high efficiency and energy saving;
♦ Offer machine installation and system test, users only need to finish
the installation of refrigerant and cooling water;
♦ Factory testing: each refrigerating unit is on load test of not less than
12 hours in the factory.
Structure design
A fully closed piping design, high efficiency plate heat exchanger used to reduce the
demand for the thermal fluid utilization while providing the system to achieve the rapid
ups and downs in temperature.
Display funcation
Displays various information on the touch screen.
Process Control Schematic diagram
High repetative of tempeature control effect
Each cycle curve slope is consistent and greatly improve the consistency of production thermostatically control environment.
