Oil Chiller: Your Complete Buying Guide from TopChiller

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.

Let’s have a look at what’s the working principle of an oil chiller?

The oil pump inside the oil chiller 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 oil chiller through the temperature sensor.

To ensure that the oil temperature is always controlled within the normal working range.

How does oil chiller works?

The working principle of your oil chiller:

Using Freon in the internal vaporization and heat absorption principle of the evaporator for cooling.

When oil chiller working, the oil pump extracts oil from the machine oil tank to the evaporator of the cold oil machine for heat exchange, and the cooled oil is cooled from the cold oil.

The oil chiller exits the output and sends it back to the tank to mix with the hot oil.

The continuous circulation of the oil reduces the temperature of the entire oil tank.

The temperature controller of the oil chiller automatically controls the opening and closing of the unit through the temperature sensor, so that the oil temperature is automatically constant at the set temperature.

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.

Oil Chiller

hydraulic oil chiller

The oil chiller in the form of shell and tube means that the evaporator is a 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 of an oil chiller is based on an 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 that can provide constant cooling oil for industrial process machines.

1, CNC machining center, CNC grinding machine, broaching machine, CNC woodworking machine, CNC punching machine, CNC lathe, high-speed lathe

Keep the processed objects at a constant temperature to prevent thermal deformation, ensure processing accuracy and shorten production time.

Specially designed exchangers are not easy to block after the steel scraps are processed.

4, Hydraulic machinery or hydraulic oil station

The heat generated in the machining process will cause the temperature of the processing equipment to rise, which will cause the processing equipment to be deformed by heat.

The high oil temperature will cause the oil quality to deteriorate and accelerate, which will make the working condition of the equipment unstable, cause errors, accelerate the wear of the tool, and cannot guarantee the parts.

So now an oil chiller will do its job for your hydraulic oil station.

How to install an oil chiller?

What are the normal installation steps of your oil chiller?

After purchasing the oil chiller, the user must carry out regular and standardized installation, in order to use the oil chiller well, We come to know 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, this 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, the environment of  installation of an 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 oil chiller and other objects or walls is more than one meter.

Of course, you must consider there should have a certain amount of space for future maintenance.

2. The presence of dangerous gases such as inflammable and explosive gases is prohibited around the oil chiller, 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.
