Compact heat recovery system for laboratories and industry, with integrated supply air system
Task:
By implementing the applicable heat insulation regulations for buildings, the rooms become more and more airtight, so that a natural inflow of supply air into the rooms no longer occurs. A negative pressure is created in a very short time. Escape routes are obstructed by doors that are difficult to open. The exhaust air monitoring of the fume cupboards switches to malfunction.
Solution:
Compact heat exchanger with integrated supply air system for the school and laboratory areas, with a requirement of 1-3 fume cupboards and/or permanently extracted hazardous substances cabinets.

Our ceramic heat exchangers have been employed successfully in regenerative thermal oxidation, acting as an alternative to conventional fillings with ceramic bulk fill materials.
The most significant advantage over conventional ceramic saddles consists in maximum heat recovery with minimum loss of pressure.
Clearly defined, straight flows prevent the accumulation of particles as well as chemical attacks.
Because of the high-quality materials used and their careful processing, our heat exchangers offer outstanding resistance to chemical, thermal and mechanical influences.

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 heat exchanger is a mechanical device designed to efficiently transfer thermal energy between two or more fluids or between a fluid and a solid surface. The primary purpose of a heat exchanger is to facilitate the exchange of heat while keeping the fluids or substances involved physically separate. This process is essential in various industrial, residential, and commercial applications for heating, cooling, and energy recovery.

Type: Shell and tube heat exchangers, finned tube heat exchangers, double-pipe heat exchangers
Material: Aluminum, copper, stainless steel, alloy steel, carbon steel, etc.
Dimensions:
- Size and geometry of the heat exchanger
- Number and length of tubes or plates
- Diameter and length of shell (for shell and tube heat exchangers)
Fluid Specifications:
- Types of fluids involved (hot and cold fluids)
- Flow rates of each fluid
- Inlet and outlet temperatures
Thermal Performance:
- Heat transfer rate (in kilowatts or BTUs per hour)
- Overall heat transfer coefficient
- Heat transfer surface area
Efficiency: Effectiveness of the heat exchanger in transferring heat between fluids.
Pressure Drop:
- Pressure loss or drop across the heat exchanger
- Flow resistance of the heat exchanger
Operating Conditions:
- Maximum and minimum operating temperatures
- Maximum and minimum operating pressures
Construction Details:
- Fin type and density (if fins are used)
- Tube or plate thickness
- Welding or joint specifications
Standards Compliance: Adherence to industry standards and certifications.

Heat exchangers play a crucial role in a wide range of applications across various industries, contributing to energy efficiency, temperature control, and process optimization. Here are some common applications of heat exchangers:
- HVAC Systems
- Refrigeration Systems
- Industrial Processes
- Power Generation
- Chemical Processing
- Oil Refining
- Food and Beverage Industry
- Waste Heat Recovery
- Air Conditioning Systems
- Renewable Energy Systems
- Automotive Cooling Systems
- Marine Applications
- Geothermal Systems
- Brewing and Distilling

Wide range of products

Ice banks/cold water plants and flush coolers
Apart from single heat exchangers we are able to deliver complete ice banks/cold water plants and flush coolers. Component parts and accessories top off our product range in the heat exchanger category.
Materials available
We usually supply heat exchangers of materials 1.4301, 1.4307, 1.4404, 1.4571 and upon request, also special materials.
Qualified technical advice
Based on our long-time experience we are able to offer to our customers a profound know-how and a qualified technical advice concerning all questions on heat exchangers.

The heat exchanger is designed for selective heat extraction from production systems, such as annealing furnace or bakery ovens and their flues.
If no heat is required from the system, the bypass motor is activated to bypass the heat exchanger.
The heat exchanger can recover enough heat to heat a warehouse or offices within the same building. Even the complete hot water requirement of a building can be provided.
High grade stainless steels
The AWT heat exchanger is manufactured from high-grade stainless steel 1.4571/1.4404, a stainless steel that has been in use in high technology flue gas applications for several years. For high stress applications, a version of the AWT made from 1.4539 is available.
For applications involving extremely high flue gas tempratures. An AWT heat exchanger fabricated in stainless steel 1.4828, which has a high nickel content, can be supplied.
Even retrospective installation of an AWT heat exchanger can be cost-effective, praticularly in times of high energy costs, so that pay-back in two to three years can be achieved.
