T-Rack® vario

Summary

Product identification

The T-Rack® vario is highlighted as "the most efficient UF rack design," featuring an integrated module and rack design that is hydrodynamically optimized. It is designed for a compact footprint, customizable system configuration, and flexible system operation, contributing to low capital and operating costs.

Key features include:

• Integration of feed and drain pipes within the module end caps for an ultra-compact design.
• Footprint up to 60% smaller compared to conventional racks. For example, a 48-module configuration of the T-Rack® vario occupies 5.9 m² compared to 10.6 m² for a conventional rack.
• Scalable solution using standardized components.
• Separate filtrate headers allow each row to operate as an individual filtration line.
• Available in two- or four-row configurations.
• Capacity can be expanded later by replacing dummy modules with fully-functional ones.
• Header pipes are made of 100% PVC, which enhances corrosion resistance, especially with aggressive water types like seawater.

The smallest T-Rack® unit comprises four dizzer® modules in two rows of two, while the largest model, TR-80-4-V, features 80 modules in a four-row arrangement.
