MHCA-4-40

Summary

Product Identification

This document provides an overview for Wila Membrane Housings of type 'MHCA-4-40', designed for medium pressure applications up to 40 bar. These are tubular pressure vessels with Clamp ferrule connections for Feed, Retentate, and Permeate. They are suitable for various filtration types including Microfiltration (MF), Ultrafiltration (UF), Nanofiltration (NF), and Reverse Osmosis (RO), particularly in the food and beverage industry to reduce microbials.
