巴基斯坦采购需求：中国水冷机和工业冷水机

I am looking for a 7-10 HP water chiller refrigerator with a flow rate of 8-10 L/min for my university final year project. The main goal is to demonstrate thermal stratification in chilled water storage tanks, so I need a straightforward and practical design. The chiller should effectively cool water from around 25-30 degrees Celsius down to 4 degrees Celsius. I would appreciate a budget-friendly option since affordability is crucial for this project. Additionally, please provide information on delivery options, including charges and estimated duration for shipping to Pakistan. Keep in mind that I am not requiring advanced control functions or extensive automation, as simplicity is key for this application. Your prompt response would be greatly appreciated.
