Fully welded VAU-Bloc plate heat exchanger

Product catalog summary

Overview of VAU-Bloc Plate Heat Exchanger
The VAU-Bloc plate heat exchanger is a fully welded unit designed for high efficiency and low maintenance, suitable for high temperatures and corrosive media. Its compact design ensures high heat transfer performance with minimal pressure loss.

Company Background
VAU Thermotech GmbH & Co. KG, based in Munich, Germany, specializes in engineering and manufacturing heat exchangers, with over 30 years of experience. They offer brazed, gasketed, and fully welded plate heat exchangers.

Product Range

Brazed Plate Heat Exchangers: Used in district heating, heat pumps, HVAC, solar energy, fresh water stations, and refrigeration.
Fully Welded Hybrid-Plate Heat Exchanger: Suitable for power stations, refrigeration, sugar evaporators, natural gas production, petrochemical, chemical, pharmaceutical, and food industries.
Gasketed Plate Heat Exchangers: Applied in the food, chemical, petrochemical, and processing industries.

Design and Features
The VAU-Bloc features a fully welded plate pack without gaskets, allowing operation with aggressive and corrosive media at high temperatures. It offers various plate patterns (Tubular, Chevron, Double Dimple) for different flow conditions and media characteristics. The design allows for easy cleaning and maintenance.

Technical Specifications

Maximum operational temperature: 300°C
Maximum operational pressure: 32 bar(g)
Minimum operational temperature: -40°C
Minimum operational pressure: -1 bar(g)

Applications
The VAU-Bloc is versatile, suitable for industries such as refineries, thermal power stations, natural gas and petrochemical industries, energy technology, building technology, chemical and pharmaceutical industries, and refrigeration and heating technology.

Advantages

High operating reliability and low maintenance costs.
Adaptable to existing conditions with flexible standard-series and variety of plate patterns.
Can be mounted both horizontally and vertically.

Materials and Construction
All parts in contact with media are made from stainless steel, while pressurized parts use carbon steel. The unit's core is a fully welded plate stack, and the casing is removable for easy maintenance.

Plate Patterns

Chevron Pattern: Efficient for clean media with compact layout.
Tubular Pattern: Ideal for two-phase flow and differing flow volumes with low pressure loss.
Double Dimple Pattern: Suitable for dirtied media with low pressure loss.
