Hydraulic Oil Chillers
Say goodbye to high energy consumption! Experience an energy efficient hydraulic oil chiller.
The variable frequency design can automatically adjust the speed according to the load to avoid energy waste.
Hydraulic Oil Chillers Overview
ZLTZ hydraulic oil chiller is a cooling device that can circulate refrigeration, allowing long-term trouble-free operation in many industrial environments. It is very suitable for use in some scenarios with small heat exchange area, large cooling capacity and small temperature difference, such as matching with microchannel reactors, cold plates, heat sink plates, etc. This recirculating water chiller uses a color touch screen with a graphic display function. The navigation menu is very clear and all operations can be completed on the panel. LNEYA provides free warranty within one year and lifetime maintenance service for all products. You can trust our chillers.

Hydraulic Oil Chillers Advantages
- Energy saving: ZLTZ hydraulic oil chiller uses variable frequency compressor, so it is more energy-saving. It can automatically adjust the speed according to the actual load. When the temperature is low, it can reduce the speed without wasting energy. In addition, it does not need to start and stop frequently, and the starting current is very small, which will not cause impact on the power grid and can extend the service life of the low temperature chiller.
- Accurate control: The hydraulic oil chiller uses an electronic expansion valve. The electronic sensor can monitor the pressure and temperature changes of the circulation system in real time and automatically adjust the refrigerant flow. In addition, it is equipped with a programmable logic controller. When the load changes, it can adjust the operation mode in time to achieve precise temperature control.
- Connectable: ZLTZ hydraulic oil chiller can be used with a variety of equipment. It can be combined with cold plates, heat sink plates, microchannel reactors or ESC chucks, vacuum chucks, and can achieve different heat exchange effects. The interface size of this recirculating water chiller can be customized according to your existing equipment.

Hydraulic Oil Chillers Importance
Improve production efficiency: Some process flows require cooling of hot products. If no other measures are taken to accelerate cooling, production efficiency will be reduced. For example, in plastic processing, the control of mold temperature is crucial in processes such as injection molding, blow molding, and extrusion. Chillers can accelerate mold cooling and improve production efficiency.
Extend equipment life: Many industrial equipment will generate a lot of waste heat during continuous operation. If it is not cooled in time, it may cause equipment failure or damage due to overheating. Frequent maintenance of equipment will bring high maintenance bills to companies. Hydraulic oil chillers can cool equipment and keep them at the optimal operating temperature.
Ensure product consistency: Hydraulic oil chillers can accurately control the temperature environment, avoid large temperature fluctuations, and make product production lines more stable. For example, in plastic processing, different temperatures will affect the consistency of appearance and size of the same batch of products. Process chillers can help improve product quality.

Hydraulic Oil Chillers Applications
ZLTZ hydraulic oil chiller is often used with microchannel reactors, plate heat exchangers, cold plates, heat sinks, tubular reactors and other equipment.
It is often used to absorb the heat generated in the process, especially the waste heat generated by industrial equipment. Its application scenarios include but are not limited to the following: Laser cutting, Laser welding, Injection molding, Electro-spark machining, Turning, Shearing, Broaching, Milling, Honing, Quenching, Drilling, Extrusion, Rolling.

FAQ

This usually depends on the cooling capacity, temperature range, flow rate, cooling medium, installation space, system redundancy, etc. of the chiller.
It is generally divided into water-cooled condensers and air-cooled condensers. The air-cooled version of this industrial chiller uses a microchannel heat exchanger, and the water-cooled version uses a plate heat exchanger.
Including evaporator, condenser, compressor, expansion valve, temperature control system, etc.
