Air-to-Air Shell and Tube Heat Exchangers
Durable air-to-air efficiency
Our heavy-duty, most robust heat exchanger for very high temperatures and very dirty exhaust air streams, where a plate heat exchanger just will not work. PRE-heat, Inc. manufactures a wide variety of industrial, air-to-air, shell and tube heat exchangers.
Our high-quality, rugged shell and tube heat exchangers are used as primary and secondary heat exchangers on all types of VOC abatement or fume incineration, including catalytic, thermal recuperative, and thermal regenerative incinerators. They are also used to recover valuable heat energy from industrial furnaces, kilns, ovens, and dryers of all types.
Recapture
PRE-heat industrial air-to-air technology captures exhaust heat waste.
Reheat
The air is then reheated through a low-energy efficient process.
Recycle
Heated air is reused across various applications, saving the environment and money.

Airlock Design
Our systems use a proprietary airlock floating tube expansion design to eliminate the destructive forces caused by uneven growth from partial heat exchanger plugging. This alone dramatically increases the lifecycles of our heat exchangers.
Versatility & Sustainability
PRE-heat can use in-line and staggered tube patterns, along with triangular, rotated triangular, square, and rotated square as well as multiple shell side flow passes and multiple tube side passes, with full or partial baffles. This allows us to design the proper exchanger to meet your performance needs and fit into the space required.
Tube Applications
Our air-to-air shell and tube designs are commonly seen in industries
with high temperatures and very dirty exhaust air streams. They
can be utilized in heat exchangers for all types of VOC abatement for fume incineration. They can also recover heat energy from
industrial furnaces, kilns, ovens, and dryers of all types.
