Single Pump Dual Temperature 3000W Laser Cutting Chiller HL-3000-QG2/2
3000W Fiber LaserDual Temperature8.7 kW Cooling
Product Summary — The HL-3000-QG2/2 is a dual temperature laser cutting chiller built for 3000W fiber laser cutting machines. A single pump feeds the dual temperature circuit, delivering 8.7 kW of cooling capacity with 3.5 kW rated power on a 1P 220V/50Hz supply. Water temperature is controlled within 22–29.5°C, with standard (±3°C) or high precision (±1°C) regulation and automatic switching between the two modes. The intelligent digital display controller runs the unit fully automatically, and alarm outputs for low flow, high water temperature, low temperature and low water level keep the laser source protected during continuous production.

Key Features
- Single-pump dual-temperature designOne 0.63 kW pump serves the dual temperature circuit, keeping the cabinet compact, the operation simple and the cooling performance stable on the production floor.
- Matched to 3000W fiber lasers8.7 kW cooling capacity with 3.5 kW rated power supports 3000W fiber laser cutting machines, so the laser source and optics stay inside their working temperature window.
- Two precision modesStandard ±3°C or high precision ±1°C regulation, with automatic switching between high-precision and standard-precision modes and a 22–29.5°C water temperature control range.
- Water circuit filtrationA filter inside the water circulation system keeps the coolant clean, protecting the pump and the cooling passages during long production runs.
- Alarm outputs and protectionsSignal outputs for low flow, high water temperature and low temperature, plus a low-water-level alarm, compressor time-delay protection and equipment overheat protection.
- Intelligent automatic controlThe digital display controller runs the chiller fully automatically, with intelligent switching to a winter anti-freeze mode and energy-saving cooling control in summer.

Materials and Structure
Wetted and structural materials
Cast iron and stainless steel SS304 are used in the chiller construction. The water circulation system incorporates a filter to keep the coolant clean before it returns to the laser and optics circuit.
Cooling and control layout
A single pump serves both temperature circuits. The intelligent digital display controller manages temperature regulation, alarm outputs and protection logic, including compressor time-delay protection and a summer cooling / winter anti-freeze operating mode.
Cabinet and intelligent digital controller
Compact dual temperature chiller body
Applications
The HL-3000-QG2/2 is used for laser cooling on 3000W fiber laser cutting machines, and within laser processing and plastic molding machine installations where a compact water chiller is required. It removes the heat generated by the laser source and related equipment, stabilises the cooling temperature and supports processing performance and operational reliability under continuous laser operation and changing thermal loads.

Customization
Order configuration covers the temperature precision mode (standard ±3°C or high precision ±1°C). Because the chiller must match laser power, heat load, flow, pressure and ambient conditions, buyers are asked to confirm their laser source, working environment and water quality requirements before shipment; final configuration is confirmed against the model datasheet. The manufacturer is certified to ISO 9001 for the design, production, sales and after-sales service of water chillers up to 120 kW (certificate 02125Q11006R4M, HuaXin Certification Center, valid to 26 July 2028).
Field Experience
Chillers from this manufacturer are used for laser cooling of laser cutting, welding and engraving equipment, with reported service durations of 5–10 years in customer installations and a focus on stable performance, energy saving and equipment-life support. Products have been successfully matched with well-known domestic laser companies such as Senfeng, Bodor and HG, and are exported to markets including Germany, Russia, India, Turkey, Vietnam, Poland, France, Italy, the United States, Brazil, Mexico and the Middle East.
