With the explosive growth of artificial intelligence and high-performance computing power, liquid cooling technology has become the standard heat dissipation solution for data centers, energy storage power stations and supercomputing centers. As the "blood" of liquid cooling systems, the annual market demand growth rate of computing power coolant exceeds 30%. During this critical window period of industrial capacity expansion, the filling accuracy, automation level and whole-line coordination capability of coolant filling machines directly determine the delivery efficiency and cost control capacity of coolant manufacturers.
Marchi Packaging Equipment Co., Ltd., a powerful original manufacturer specializing in domestic packaging automation, has recently launched a 25L fully automatic coolant filling and palletizing production line targeting the liquid cooling and industrial coolant industries. Composed of filling, capping, labeling, carton unpacking and packing, carton sealing and strapping, automatic palletizing and other units, this production line realizes full-process automatic operation from empty barrel feeding to finished product pallet warehousing.

II. Precise Model Selection: 25L Four-head Filling Machine Suitable for Various Coolant Packaging
The automatic coolant filling machine mainly promoted by Marchi is 25L fully automatic liquid filling machine with four heads. Fully taking into account the physical properties of coolants including ethylene glycol type, propylene glycol type, pure water-based type, fluorinated liquid and other types, the equipment highlights three major advantages in core configuration:
- Weighing Feedback System: Each filling head is equipped with independent weighing sensor and feedback control unit. The filling volume of each head can be set and finely adjusted separately to ensure highly consistent net content during simultaneous filling of multiple barrels.
- Submerged Filling Structure: The filling nozzle automatically extends below the liquid level inside the barrel for stable bottom filling, which effectively inhibits foam generation and is applicable to foaming-prone materials such as coolant, antifreeze and cutting fluid.
- Intelligent Sensing and Safety Protection: Photoelectric sensors and proximity switches monitor barrel positions in real time to realize no filling without barrels. The main machine will automatically stop and give an alarm in case of barrel jamming to avoid material waste.
Key Parameters:
Equipment overall dimension: 3500×1700×2300mm
Applicable barrel specification: Length 160～360mm, Width 100～300mm, Height 250～500mm, barrel mouth diameter no less than 40mm
Production capacity: 450 barrels per hour under 30kg specification
Filling accuracy: ≤±0.3%
Power supply: AC220V, 50Hz, total power 2kw
The whole machine is manufactured in accordance with GMP standards. All pipelines and exposed parts in contact with materials are made of stainless steel with corrosion resistance and easy cleaning performance. All pipeline connections adopt quick-installation structure for convenient disassembly and cleaning, meeting the demands of long-term continuous production.
III. Full-process Packaging Procedure: From Filling to Automatic Palletizing
Marchi coolant filling production line covers the complete industrial chain from empty barrel feeding to finished pallet delivery instead of only focusing on filling process. The specific packaging steps are as follows:
- Empty Barrel Conveying and Positioning
Empty barrels are delivered to the filling area via roller conveyor lines. Photoelectric sensing components automatically identify barrel positions and realize synchronous positioning of four filling heads.
- Submerged Quantitative Filling
Filling nozzles extend into barrels. PLC cooperates with weighing feedback system to precisely control filling volume. The system will stop operation and send alarms immediately in case of no barrels or barrel jamming during filling.
- Automatic Capping and Labeling
Filled coolant barrels are sent to the capping station. Pneumatic capping devices complete sealing with adjustable torque. Then aluminum foil sealing is realized via electromagnetic induction sealing machine, followed by annular barrel labeling and production date inkjet printing through automatic labeling devices.
- Online Weight Checking and Unqualified Product Rejection
Each barrel is rechecked by dynamic weight checkers. Unqualified products exceeding allowable error range are pushed out by automatic rejecting devices to ensure finished product qualification rate.
- Automatic Carton Unpacking and Packing
Fully automatic carton unpackers shape and seal carton bottoms. Coordinate-type packing mechanisms or robots place finished barrels into cartons in preset arrangement modes.
- Carton Sealing, Strapping and Automatic Palletizing
Filled cartons are sealed with adhesive tapes by automatic carton sealing machines, then cross-shaped or tic-tac-toe strapping is completed by fully automatic strapping machines to prevent loosening during transportation. Finally, high-level palletizing systems or robot palletizing devices stack cartons layer by layer on pallets according to preset layers and pallet patterns to form compact and pressure-resistant whole pallets. After palletizing completion, automatic winding machines wrap goods with stretch films, and finished products are delivered to warehouse buffer areas via pallet output conveyor lines.
IV. Diversified Material Adaptability
This series of coolant filling production line manufactured by Marchi is not only applicable to computing power coolant, but also widely used for various liquid products including vehicle antifreeze coolant, engine coolant, wind power gearbox coolant, energy storage system coolant, metal working fluid, glass water, brake fluid, hydraulic oil, lubricating oil and so on.
V. Solutions to Customer Pain Points: How Marchi Guarantees Coolant Filling Quality
Through in-depth communication with numerous coolant manufacturers, Marchi has summarized three most prominent filling pain points and put forward targeted solutions.
Pain Point 1: Large fluctuation of filling accuracy leading to excessive or insufficient net content
Marchi Solution: Independent weighing feedback is equipped for each filling head to control accuracy within ±0.3%, far exceeding the accuracy level of ordinary liquid filling machines. Fine compensation adjustment for single head is supported to realize stable filling even for coolant batches with different densities.
Pain Point 2: Overflow of foaming materials after filling causing contamination on barrel bodies and sealing positions
Marchi Solution: Adopt submerged filling mode to greatly reduce foam generation through bottom liquid injection. Short-time standing after filling ensures stable liquid level before lifting filling nozzles, keeping barrel mouths clean without residues.
Pain Point 3: Coolant is corrosive and pipelines of ordinary equipment are prone to aging
Marchi Solution: All parts of the whole machine in contact with materials are made of stainless steel featuring corrosion resistance and oxidation resistance. The quick-install pipeline structure facilitates regular cleaning and maintenance, extending equipment service life and suiting long-term continuous operation in chemical workshops.
