I am interested in sourcing a custom-built 0.5-ton vertical flake ice evaporator drum, designed for operation with Ammonia (R717) refrigerant. It's essential that the construction utilizes carbon steel or stainless steel, excluding any copper components. The unit will be installed in a gravity-mounted setup within a 40-foot High Cube container, collaborating with a separate 3-phase compressor skid, along with an external water-cooled closed-loop cooling tower. Could you please provide me with a detailed price quote for the evaporator unit, along with shipping dimensions and your current lead times for manufacturing and delivery? This information is crucial for us to move forward efficiently, so your prompt response would be greatly appreciated. Thank you!
