Air Cooled Chiller Unit 20HP Industrial Water Chiller For Rubber And Plastic

Tailored Design for Rubber & Plastic Industry Needs

Rubber and plastic production processes (such as plastic injection molding, extrusion, rubber vulcanization) have strict requirements for cooling—high heat output, easy mixing of impurities (plastic particles, rubber scraps) in circulating water, and need to maintain stable low temperature for a long time. This 20HP air-cooled industrial chiller is developed for these pain points, with targeted optimization in heat exchange efficiency, anti-clogging performance, and temperature stability.

For example, aiming at the problem of easy accumulation of plastic particles in the cooling pipeline of injection molding machines, the chiller is equipped with a high-precision filter at the water inlet. It can effectively intercept impurities, avoid blockage of the mold cooling channel, and reduce the frequency of manual cleaning by 70%.

Powerful Refrigeration to Cope with High Heat Load

The chiller has a rated cooling capacity of 56.2Kw (48332Kcal/h), which can quickly take away the large amount of heat generated during the operation of rubber and plastic equipment. In plastic extrusion production, it can control the temperature of the extruder barrel at 18-25℃ (adjustable), ensuring that the plastic melt has stable fluidity and avoiding product deformation caused by excessive temperature of the extruded material.

In the rubber vulcanization process, it can stably control the temperature of the vulcanizing machine platens at 35-45℃, ensuring sufficient rubber vulcanization reaction and improving the uniformity of product hardness and elasticity. The chiller adopts a dual-scroll compressor parallel design—when the heat load is low (such as the start-up stage of equipment), only one compressor operates to save energy; when the heat load increases (such as continuous injection molding production), the second compressor automatically starts to ensure stable cooling capacity, with an average energy saving of 20% compared with single-compressor models.

Stable Temperature Control to Ensure Product Quality

Rubber and plastic products have high requirements for temperature consistency—even a small temperature fluctuation (more than ±2℃) may lead to defects such as uneven thickness of plastic parts and insufficient vulcanization of rubber products. This chiller is equipped with a single-chip microcomputer temperature control system, which can control the outlet water temperature within the range of 5-35℃, and the temperature control precision reaches ±1℃, far higher than the industry's general ±2-3℃ standard.

In actual application, when the injection molding machine switches between different molds or adjusts the production speed, the chiller can quickly respond to the temperature change (response time ≤ 2 seconds) and adjust the refrigeration output in real time, ensuring that the mold temperature remains stable. This effectively reduces the scrap rate of rubber and plastic products, and the average scrap rate can be reduced by 5%-8% for enterprises with large-scale production.

Durable Structure Adapt to Harsh Working Environment

Rubber and plastic workshops usually have high ambient temperature (up to 40℃), and there are oil fumes, plastic dust and other pollutants in the air, which put forward high requirements for the durability of the chiller. This product has made multiple enhancements in structural design:

• Condenser Efficiency & Anti-Clogging: Adopts a microchannel condenser with an all-aluminum alloy structure. Compared with traditional finned condensers, its heat exchange efficiency is increased by 25%, and the compact channel design is not easy to accumulate plastic dust and oil fumes. At the same time, it is equipped with an automatic cleaning brush, which can regularly clean the surface of the condenser without stopping the machine, ensuring long-term stable heat dissipation performance even in dusty workshop environments.​
• Cabinet Protection: The outer shell is made of 1.2mm thick galvanized steel plate with electrostatic spraying, which has strong corrosion resistance and scratch resistance. It can resist the erosion of oil fumes and chemical volatile substances in the workshop, and the service life is extended to more than 10 years.​
• Electrical Component Protection: The electrical control box is designed with full sealing and heat insulation. It can prevent dust and water vapor from entering, and avoid short circuit faults caused by high temperature and humidity in the workshop.

Easy Operation & Maintenance for Industrial Scenarios

Considering that the operators in rubber and plastic workshops may not have professional refrigeration knowledge, the chiller is designed with a mechanical button operation panel (no touch screen). Key parameters (water temperature, pressure, running status) are displayed through a digital display screen, and functions such as temperature setting, start-stop control and fault query can be completed with simple button operations, which is more suitable for the operation habits of on-site workers and avoids misoperation caused by complex interfaces.

In terms of maintenance, the chiller has a "maintenance-friendly" design: the filter element can be replaced without disassembling the pipeline, and the replacement time is shortened to 5 minutes; the compressor, expansion valve and other key components are installed in the independent maintenance area, with a large maintenance space, which is convenient for engineers to inspect and repair. At the same time, the system has a fault self-diagnosis function—once a fault occurs (such as low water flow, high compressor temperature), it will immediately send a sound and light alarm, and display the fault code and solution on the digital screen, reducing maintenance time by more than 60%.

Application Scenarios in Rubber & Plastic Industry

1. Plastic Injection Molding: Cool the injection mold and barrel, control the mold temperature to 15-25℃, ensure that the plastic parts are quickly shaped, reduce warpage and shrinkage, and improve the qualified rate of products.​
2. Plastic Extrusion: Cool the extruder barrel, die head and calender, maintain the temperature of the melt at a stable level, and ensure the uniformity of the thickness and surface smoothness of the extruded products (such as plastic pipes, films).​
3. Rubber Vulcanization: Cool the vulcanizing machine platens, control the vulcanization temperature at 35-45℃, ensure that the rubber undergoes sufficient cross-linking reaction, and improve the elasticity, wear resistance and aging resistance of the rubber products.​
4. Rubber Extrusion: Cool the rubber extruder and mold, prevent the rubber from scorching due to excessive temperature during extrusion, and ensure the stability of the shape and performance of the rubber products (such as rubber hoses, sealing strips).
