I'm looking for a cold storage solution specifically designed for preserving seasonal vegetables. The capacity should be able to handle batches ranging from 500 to 1000 kg. It's important that the system maintains optimal temperature and humidity levels to ensure the best quality of the produce over time. Additionally, I'll need details regarding the energy efficiency of the equipment, as well as any relevant technology used for temperature control and insulation. Please also provide information on the required maintenance, any warranties available, and general lead times for delivery. Looking forward to your prompt response with the specifications and pricing!
