巴基斯坦采购需求：空气冷却器冷凝器单元，半封闭式冷凝器单元

I'm interested in sourcing condensing units and would like more detailed information. Specifically, I'm looking for the technical specifications you offer, a breakdown of available models, and insights into their performance characteristics. Additionally, please include quotes on pricing for different quantities, as well as lead times for delivery. Moreover, it would be great to know about the warranty options and any post-sale support you provide. If you have any promotions or special offers currently running, please highlight those as well. A timely response would be greatly appreciated since I'm keen to move forward with this procurement.
