Pillow Plate Exhaust Air Recuperators
Pillow plate heat recovery for heavily dust-laden exhaust air, combining compact heat transfer surfaces with integrated cleaning-in-place.
Your process. Your requirements.
Built around the application.
This pillow plate recuperator configuration is designed for demanding exhaust air applications. It is suited to dust-loaded streams in food and dairy production, including spray drying, as well as chemical, paper and textile processes. Condensation heat recovery can be incorporated where appropriate.
The designation ProcessTherm (also written “Process Therm”) is also used in the industry for pillow plate heat recovery systems handling dust-laden drying air.
Features & options
- Pillow plate heat transfer surfaces with integrated CIP.
- Materials and plate spacing selected for the operating conditions.
- Compact arrangement for industrial heat recovery.
- Cleaning of internal surfaces without disassembling the heat exchanger.

Why Anytherm
Process understanding.
Practical engineering.
Personal support.
We work through the requirements with your team and develop a scope that fits the process, installation and operating needs.
Selection driven by the process
We assess thermal duty, dust loading and cleaning needs before specifying the configuration.
Heat recovery integration
The exchanger can be considered as part of a wider recuperation or circulation system.
Independent project engineering
Anytherm coordinates the application and selects suitable technology and production partners for the project.
Cleaning-in-place for contaminated exhaust air
The CIP system uses a cleaning solution to clean internal surfaces. It is typically fitted at the top, with bottom installation and circulation nozzles in transition sections available according to the configuration. Cleaning frequency and operating arrangements depend on the deposits and process.
Select the equipment for the complete duty
Temperature, pressure, vacuum, material and cleaning conditions must be evaluated together. Published limits describe possible configurations and are not a combined operating point or a standard rating for every unit.
Connect equipment and energy expertise
The useful heat matters.
A heat recovery concept should connect available heat with demand at suitable temperature levels. Our heat recovery and pinch analysis expertise helps assess the opportunities before selecting equipment.

Before your enquiry
Practical questions
What is CIP?
Cleaning-in-place cleans internal equipment surfaces using a cleaning solution without disassembly. The cleaning arrangement must match the process media and deposits.
Do all published limits apply simultaneously?
No. The feasible temperature, pressure, vacuum and material combination must be confirmed for the specific design.
What should I include in my enquiry?
Share exhaust air flow, composition and dust loading, temperatures, pressure or vacuum, available cooling medium, cleaning requirements and space limits.
Share what you already know. You do not need a complete specification to start the discussion.
