There are two different construction types.
It's possible to create a design using a little construction space using the customer's data. The Thermo-Fluid S is connected directly between the oven pipe (or the heating system) and the chimney.
The operating temperatures are up to 300°C (standard). The Thermo-Fluid S is low maintance with low pressure drop in the flue gas. Depending on the application you can have energy savings up to 15 %.
A bigger construction is the Thermo-Fluid M, which is optimised for utilisation of waste heat from process air, flue gas or exhaust air. An energy yield of up to 1600 kW is possible, whereupon the pressure drop in the process air is less than 1.5 mbar. The pressure drop in water circuit is less than 200 mbar.
This Shell and Tube heat exchanger is low maintance using the small type of construction. The Thermo-Fluid M modular and the standard temperatures are up to 300°C too.
Both Shell and Tube Heat Exchangers are low maintance. One-off or batch production of the devices ensures that the design is always customised and high efficiency.

ACE can produce heat exchangers for every field of application.
Depending on requirements and technical feasibility, the most varied
tube-bundle heat exchangers as well as tube-in-tube heat exchangers are
manufactured. On the basis of years of experience, the tube-to-tubesheet
connections are either welded in, rolled in or also hydraulically
pressed. The petrochemical industry, especially, values ACE in this
sector as a competent and reliable partner for individual solutions.

We construct, produce and deliver heat exchangers in the most varied
formats for customers' individual use in the most different industrial
fields on the international market.

A tube bundle heat exchanger is a type of heat exchanger that uses a bundle of tubes to transfer heat between two fluids. These exchangers are widely used in various industrial applications where efficient heat transfer is required.
Tube bundle heat exchangers facilitate the transfer of heat between two fluids by circulating them in separate channels within the exchanger. One fluid flows through the tubes (the tube-side fluid), while the other fluid flows around the outside of the tubes (the shell-side fluid). Heat is transferred from the hot fluid to the cooler fluid through the walls of the tubes.

Construction:
Tube Bundle: The tube bundle is the core component of the heat exchanger, consisting of a series of tubes arranged in a parallel or helical configuration. These tubes are typically made of materials such as stainless steel, copper, or carbon steel and are designed to withstand high temperatures and pressure differences.
Shell: The shell surrounds the tube bundle and contains the shell-side fluid. It is usually cylindrical in shape and can be made of materials such as carbon steel or stainless steel. The shell may include baffles or other internal components to enhance fluid flow and heat transfer.
End Caps: End caps seal the ends of the shell and provide access for maintenance and cleaning. They are typically bolted or welded to the shell.
Tube Sheets: Tube sheets are plates that support the tube bundle at both ends and provide a leak-proof barrier between the tube-side and shell-side fluids. They are usually made of the same material as the tubes and are welded or bolted to the shell.
Types:
U-Tube Heat Exchangers: In U-tube heat exchangers, the tubes are bent into a U-shaped configuration, with the tube bundle supported by tube sheets at both ends of the shell.
Straight Tube Heat Exchangers: In straight tube heat exchangers, the tubes run straight through the shell and are supported by tube sheets at both ends. This configuration allows for easier maintenance and cleaning compared to U-tube designs.
Floating Head Heat Exchangers: Floating head heat exchangers feature a removable tube bundle that can be pulled out of the shell for maintenance or replacement without disconnecting the shell-side piping.

Tube bundle heat exchangers are used in a wide range of industries and applications, including chemical processing, petroleum refining, power generation, HVAC systems, food and beverage processing, and marine engineering.
They are commonly used for tasks such as heating or cooling process fluids, condensing vapors, evaporating liquids, and recovering waste heat.
