There are lubrication oil cooling chiller and hydraulic oil cooling chiller. Both Oil cooling units playing important roles in a machine tool or mechanical processing.
Why Oil chiller is so important for modern industries？As we all know: boring heat is generated from headstock bearing and gearbox of machine tools.
The main spindle heats up and the spindle deviates from the center of the column and head. This will result in poor accuracy and bad working performance.
Oil cooling chiller can provide constant coolant to control heat generation at the headstock, and the thermal deviation will be eliminated.
The oil cooling unit lubricates the headstock gears and removes the heat generated. This function is helpful to improve machine processing accuracy.
As a leading portable oil chiller manufacturer with 20 years experience, each oil chiller unit integrates with a hermetic scroll compressor, cooling fan, insulated SS tank, oil pump, and automatic by-pass, drain valve and oil level indicator, R134a or R407c refrigerant is also charged before delivery.
All oil cooling chillers have full safety protection devices like high/ low-pressure protection, anti-freeze protection, thermal overload protection, speed control, and safety guard oil flow protection.
This kind of oil chiller unit temperature range from +20°C to +35°C for the standard unit. Environment conditions are between +15°C and +55°C for specific applications.
Oil Chiller: Your Complete Buying Guide
What is an oil chiller?
The oil chiller sometime called oil cooler, is cooled by the principle of evaporation and heat absorption of the refrigerant.
The oil pump extracts oil from the machine oil tank to the refrigeration system for heat exchange treatment, and the cooled hydraulic oil is returned to the machine oil tank through the oil cooler oil discharge line, So that the oil temperature of the whole oil is maintained by the continuous circulation of the oil.
Continuously falling, the oil chiller responds to the temperature of the oil in the fuel tank through the temperature sensor of the temperature controller.
The oil chiller user can set the temperature according to the actual work and control the oil temperature.
The temperature controller automatically controls the operation of the cold unit through the temperature sensor. To ensure that the oil temperature is always controlled within the normal working range.
Types and functions of oil chiller
Oil chillers can be divided according to the way of cooling or heat dissipation, it can be divided into water-cooled oil chiller and air-cooled oil chiller.
A water-cooled oil chiller means that the condenser relies on an additional cooling tower for heat dissipation. But the air-cooled oil chiller relies on the fan itself to dissipate heat.
According to its external shape and structure, oil chillers can be divided into two types: a closed loop oil chiller and an open loop oil chiller.
A closed-loop oil chiller refers to a packaged box with sheet metal on the outside.
The open loop oil chiller has no outer casing, its cold suspect and evaporator are shell-shaped, the upper part of the evaporator is a compressor, there is no oil pump, the oil tank and the circulating oil pump need to be additionally configured.
According to the structure of the chiller evaporator, oil chiller can be divided into two types: an oil chiller using shell and tube or plate heat exchanger.
Hydraulic Oil Chiller
The oil chiller in the form of shell and tube means that the evaporator is shell-and-tube type. The oil pump can be placed inside the oil chiller, and it can be placed outside the equipment. The outer casing may or may not be.
The condenser is based on air-cooled or water-cooled type. An open type of oil chiller means that the evaporator is in an open form and placed inside the oil tank.
The condenser is also determined according to the form of water cooling or air cooling.
Oil chiller industrial applications:
Oil Chillers are very common industrial devices can provide constant cooling oil for industrial process machines.

How to install oil chiller? Oil chiller installation steps
After purchasing the oil chiller, the user must carry out regular and standardized installation, in order to use the oil chiller well. So, how to install an oil chiller normally?
The following are the installation steps of the oil cooling chiller:
First, the handling of the oil chiller
When transporting the oil chiller unit, the oil chiller should be prevented from being hit by other things, and it should not be skewed or inverted to keep the original of the oil chiller as much as possible.
Second, install the environment of the oil chiller
1. The oil chiller should be installed in a relatively ventilated and ventilated place in the house, and ensure that the surrounding environment is dried.
And at the same time, ensure that the distance between the inlet and outlet of the chiller and other objects or walls is more than one meter. There is a certain amount of space for future maintenance.
2. The presence of dangerous gases such as inflammable and explosive gases is prohibited around the cold oil machine, and high-heat objects are not allowed.
At the same time, the oil chiller is not exposed to direct sunlight.
3. The specific position of the installation of the oil chiller is determined by the user according to the actual situation.
The structure of the installation position for the oil cooling chiller should be able to withstand the weight of the unit and the force transmitted during normal operation.
Third, the oil pipe
1. When piping the oil circuit of the oil chiller, it must be carried out according to a certain pressure range to ensure the rationalization of the pipeline.
2, the size of the pipe is determined according to the model of the oil chiller, the pipe needs to be dry, ashless, clean, no oil and so on.
3. The number of joints used for piping should be as small as possible to reduce the resistance caused to the oil circuit.
4, when it is not necessary, do not use the valve in the pipeline, because even if the valve is fully opened, the pipeline cannot avoid the loss of relatively large pressure.
5, the length of the pipe is determined according to specific attributes, the length of the oil path should be minimized, usually should not exceed five meters.
6. The connection between the pipes must be firm and sealed, and the joints should be sealed with tape to prevent leakage of air and oil.
Fourth, the oil absorption filter
In order to improve the heat exchange efficiency of the oil chiller, the life of the oil chiller is effectively extended, and a filter capable of sucking oil must be installed at the oil suction port of the oil pipe.
Five, the installation of the oil tank
1. In order to fully integrate the high and low oil temperatures, careful consideration should be given to the size of the fuel tank and the separation inside the fuel tank.
2. In order to prevent air from mixing into the oil passage, the oil outlet of the fuel tank should be lower than the surface of the liquid.
Sixth, the wiring of the power supply
1. The power supply and circuit controller specifications are strictly in accordance with the requirements of the manual.
2. The power cord should be configured according to the standard of electrical principle.
3. The air switch should be configured independently.
