A custom industrial chiller is widely used in industries such as agriculture, chemical processing, and shipbuilding. Pengqiang will customize the solutions for free according to the actual conditions of these industries, and then make the machines. Since special industries have more professional requirements for temperature control, compressor stability, explosion-proof and corrosion-proof, Pengqiang's custom chiller series was born.
We offer custom industrial chillers to meet your specific dairy processing needs, from compressor configuration to smart controls. Below are the key customization options available:

Choosing the right industrial chiller starts with understanding your application scenario and the site conditions. The more accurate your requirements, the more optimized your solution will be — both in performance and cost.
Step 1: Define Your Cooling Needs
Key Question | Example Answer |
What will you cool? | Milk / Mold / Process water |
Desired outlet temperature? | e.g. 4°C |
Flow rate needed (L/h)? | e.g. 1000 L/h |
Installation environment? | Indoor / Outdoor |
Special control requirements? | PLC / Remote Monitoring / Alarms |
Understanding these parameters will help determine the correct chiller type, cooling capacity, and control configuration.
Step 2: Calculate Cooling Capacity
Cooling capacity is expressed in kW, kcal/h, or BTU/h, and is crucial for proper chiller sizing.
If it's too complex, just tell us your parameters — we'll help you calculate.
Example:
To cool 1000 liters of milk from 35°C to 4°C within 1 hour, you'll typically need 10–12 kW cooling capacity.
Cooling Capacity Formula （with Explanation）
Formula:
Cooling Capacity (kW) = Flow (L/h) × Specific Heat × Temperature Drop ÷ 860
Where:
Parameter | Description |
Flow (L/h) | Volume of fluid to be cooled per hour |
Specific Heat | 4.186 (for water) |
Temperature Drop | Inlet Temp − Outlet Temp (°C) |
860 | Conversion factor (to kW) |
Step 3: Confirm Basic Technical Requirements
Parameter | Example / Options |
Required temp range | 5 – 15°C |
Cooling fluid type | Water / Water-Glycol |
Flow rate | e.g. 60 L/min or 3.6 m³/h |
Power supply | 380V / 3PH / 50Hz |
Installation space | Dimensions available |
Control type | Mechanical / Microcontroller / PLC |
These inputs help us design an efficient, energy-saving, and cost-effective solution tailored to your operation.
