What is Inverter Plastic Chiller

An inverter plastic chiller provides a cooling process in plastic molding, enhancing the quality of molded products and reducing the injection molding cycle time. This maximizes the productivity of plastic molding manufacturing.

Features of Water Cooled Industrial Chiller

Protection function
The inverter plastic chiller uses a Copeland inverter compressor with R407c refrigerant for environmental protection. The inverter equipment is designed for energy saving and speed regulation. Additionally, the frequency converter offers multiple protection functions, such as overcurrent, overvoltage, and overload protection.

Easy to operate
The PLC microcomputer control with an LCD touch screen accurately controls the temperature. It features a user-friendly interface in both English and Chinese, making operation and control straightforward and comprehensive.

Durable
The chiller incorporates Germany's Schneider Electric products, which enhance the electrical protection systems. It also uses high-quality brand name pumps that ensure high flow, low noise, and long-lasting durability.

Frequently Asked Questions

Q: What is a chiller inverter?

A: Inverter technology can ensure the best chiller performance regardless of the cooling demand. With Variable Frequency Drive (VFD) technology, chillers are able to match the varying load requirements, regardless of requirement. The Inverter technology modulates the speed of the compressor's motor continuously.

Q: What is the plastic process chiller?

A: What Does a Plastic Chiller Do? Industrial plastic chillers cool down hot plastic products and maintain stable temperatures throughout production. Some processes that use plastic chillers include: Plastic extrusion: Heated plastic is forced through various forms shapes to create specific shapes.

Q: What is the difference between inverter and non-inverter chillers?

A: Unlike traditional non-inverter refrigerators that operate on a fixed-speed compressor, inverter refrigerators can run at different speeds depending on the cooling needs. This technology helps reduce energy consumption, noise, and wear and tear on the compressor.

Q: What does inverter mean in HVAC?

A: An inverter is energy saving technology that eliminates wasted operation in air conditioners by efficiently controlling motor speed. Air conditioners maintain set temperature by cooling when room temperature rises above the set temperature and heating when the room temperature falls below the set temperature.

Q: Which type of chiller is best?

A: Water-cooled chillers are typically more efficient than air-cooled chillers. Using water evaporation to dissipate heat uses significantly less energy than blowing air across a hot surface. This is thanks to water's high heat capacity. Additionally, water chillers tend to last longer than air-cooled chillers.

Q: Why do you vacuum in chillers?

A: Air and other non-condensable gases can occupy the space inside the system, which can reduce the cooling capacity and cause high head pressures, leading to compressor damage. Vacuuming the system can remove all the air and moisture, leaving the system free of contamination and ready for proper refrigerant charging.

Q: What is a garbage chiller?

A: Can accommodate 1 to 4 waste bins of 240 litres each. 1 to 4 hinged doors (depending on execution) Excecution with built-in cooling unit (machine compartment on the right) or for connection to remote cooling. Hygienic interior made of stainless steel.

Q: What is a chiller vs HVAC?

A: Industrial chillers are built to handle the cooling of various manufacturing processes (brewery cooling, hydroponic cooling, plastics cooling) directly. Conventional HVACs are built to regulate the environmental temperatures within designated spaces.

Q: Why do chillers fail?

A: Common Chiller Problems and Solutions: A Troubleshooting Guide
Incorrect operating practices, negligence to maintenance, and incorrect chiller sizing are three common causes of chiller problems. Therefore, operators must actively consider these factors to mitigate potential threats to the cooling equipment.

Q: Why do chillers surge?

A: If the cooling tower is unable to reject enough heat, this will also cause a surge. You will see the water increase in temperature and that's going to restrict how much heat can be absorbed by the condenser. Again, it won't be able to reject enough heat.

Q: Should chillers be cleaned?

A: Periodic maintenance helps control the growth of Legionnaires' disease bacteria (LDB) and other organisms. In many organizations, chillers use the most energy, so regular cleaning and maintenance ensure that they operate reliably and efficiently.

Q: Why are chillers in the basement?

A: Water cooled chillers are typically located in the basement or lowest floor of a building. This type of chiller needs a cooling tower to reject the heat from the building. The chiller produces chilled water and pushes this around the building to Air Handling Units (AHU's) and Fan Coil Units (FCU's) etc.
Three Signs It's Time to Replace Your Chiller
1.High Maintenance and Repair Costs
Maintaining an unreliable chiller can mean excess money spent on repairs every year that could have otherwise gone toward the company's bottom line. It is a considerable expense in any production setup. Whenever the chiller breaks down, there's a huge impact on the timely operation of your business, potentially delaying delivery timelines, resulting in unhappy customers. In this situation, chiller replacement becomes necessary.
2.Age of the Unit
There's no clear-cut standard for determining how long a chiller should operate, but most manufacturers recommend a replacement after about 15 to 20 years of service. Industrial chillers work hard and are in operation every single day. With age, different components of the system will inevitably wear out. Replacing individual parts and refrigerant over the years becomes an expensive undertaking, and locating spare parts for old chiller brands can become a tedious task for technicians. At this point, a new chiller will not only help you eliminate the time spent on repairs, but it will also put you in a position to leverage new technologies in industrial chiller manufacturing.
3.Higher Energy Bills
An industrial chiller is often one of the main consumers of power in an industrial facility. This unit works hard for other systems to operate properly. If you notice the power bill keeps rising, then it may be time to take a look at your chiller's efficiency levels and see if it's the culprit for increased energy costs. With age, even common electrical appliances found in homes require more power to do the same work as a new unit. By switching to a more energy-efficient chiller, you can save money on energy costs.
