南非采购需求：过滤和干燥，真空冷冻干燥机制造商

I'm reaching out to explore the possibility of importing four industrial freeze-dry machines with a capacity of 100 tons each. We're looking for detailed specifications and pricing for these units. It would be great if you could include any information regarding energy efficiency, maintenance requirements, and lead times for production and shipping. Additionally, we'd appreciate insights into the warranty and after-sales support you offer. Any brochures or product catalogs you have on hand would also be helpful as we evaluate our options. Please send the requested information at your earliest convenience, so we can move forward on this potential order.
