Product Description

Technical Specifications

FAQ

Scene-Specific Solutions for Medium-Low Temperature Requirements

For industries needing stable medium-low temperature cooling (0~-20℃) without extreme deep freezing, our Water Cooled Chiller delivers efficiency and flexibility:

Dairy & Beverage Industry: Maintains 2~6℃ for raw milk storage and -5~-10℃ for yogurt fermentation, preventing bacterial growth and ensuring product consistency.

Commercial Cold Storage: Ideal for small-to-medium supermarkets and restaurants, cooling 100~500m³ warehouses to -8~-15℃ for meat, vegetables, and prepared foods.

Brewing & Food Processing: Cools wort during beer brewing to 8~12℃ and chills fruit juices to 0~4℃ for pasteurization, reducing energy consumption by 18% vs. single-stage chillers.

Water Cooled Iron Chiller for Refrigeration

Product Design & Material Advantages

Space-Efficient & Energy-Saving Design

Compact Structure: Models like 2YG-3.2 (827×330×660mm) fit into narrow machine rooms, saving 25% of installation space compared to traditional water-cooled units.

Efficient Heat Exchange: The SLKD-series condensers use enhanced heat transfer tubes, improving heat dissipation efficiency by 22% and reducing power consumption (Pe ranges from 1.95~11.65kW).

Durable & Safe Materials

Compressor Body: Cast iron with anti-rust coating, resisting moisture corrosion in water-cooled systems; CNC machining ensures concentricity, minimizing vibration.

Refrigerant Compatibility: Works with eco-friendly refrigerants (R22, R134A, R404A, R507C) to meet global environmental standards (e.g., EU F-Gas Regulation).

Technical Support & After-Sales Service

Customization: Adjust refrigerating capacity (Qo: 9.76~47.1kW) and condensing temperature (30~70℃) based on customer process needs (e.g., brewing vs. dairy).

Remote Monitoring: Optional IoT module for real-time tracking of temperature, pressure, and power consumption; alerts sent via app if parameters deviate.

Warranty: 2-year warranty on the compressor body and 1-year on electrical components; extended warranty packages available.

Troubleshooting: 24/7 online support via WhatsApp/Zoom; engineers provide step-by-step guidance for issues like "unit not starting" or "abnormal noise".

Q: What are the common causes of wire burning in the equipment, and what are the corresponding solutions?

A: Common causes are phase loss or overload. For phase loss, check the three-phase power supply; for overload, first identify the cause of overload (e.g., excessive load, stuck components) and completely eliminate it.

Q: If a short circuit fault is found during circuit inspection, what is the primary handling step?

A: The primary step is to fully inspect the circuit, locate the short-circuit point (e.g., damaged wires, stuck components), and test the circuit continuity after repairing the short-circuit point.

Q: If an open circuit occurs in the circuit causing equipment power failure, how to quickly locate the problem?

A: Inspect the circuit in sections along the circuit path, focusing on wire joints, switch contacts, and component pins (where open circuits are likely to occur). Repair or replace the corresponding wires after finding the breakpoint.
