PRE-heat, Inc. is a leading designer and manufacturer of industrial air-to-air heat transfer equipment. The company evolved from a simple idea: "Design and deliver equipment that saves energy and exceeds the customer's performance and quality expectations."

The ILW utilizes a combination of a wave pattern to increase turbulence and an in-line dimple pattern to maintain plate spacing. This combination creates a plate heat exchanger with structural integrity and high turbulence while maintaining low pressure drop. The ILW is a heavy duty, cleanable, all welded plate type heat exchanger with the most robust primary seal weld in the industry. The all welded construction eliminates cross contamination (leakage) between the gas streams. The ILW also provides high percentage heat transfer effectiveness. Variable plate thickness, plate spacing and plate sizes are designed to meet system requirements and fine tune the system to maximize efficiency and cost. Removable access doors are available for cleaning and inspection.

Low temperature systems are fabricated using 409-stainless steel, while units for corrosive or high temperature applications utilize various grades of stainless steel and alloys. Standard materials include 304, 316, 309 and 310 stainless steels.

Since each unit is custom designed we can offer a wide range of options, such as:

Because of our years of experience with a variety of applications and materials, we build all systems with robust features such as:

The PRE-heat, Inc. team utilizes over 50 years of combined experience. We provide full design and engineering services including, sizing, material selection, and airflow design. We have successfully designed and built units for applications such as:

Pre-Heat Inc.

PRE-heat, Inc., specializes in Custom Industrial air-to-air Heat Exchangers and Packaged Heat Recovery Systems. We have been designing and building industrial, packaged air-to-air heat recovery units for over 23 years.

Our custom designed packaged heat exchanger assemblies include our proprietary designed plate type heat exchangers and shell & tube heat exchangers. By adding inlet and outlet plenums, expansion joints, bypass ducts and dampers, insulation and cladding, our heat exchanger assemblies meet in the field with our OEM customer's fume combustion chambers to form a high quality, high efficiency catalytic or thermal recuperative fume incinerator package.

Even with today's ultra high efficiency regenerative fume incinerators, there is generally enough heat available that our competitively priced insulated exchangers are widely used as secondary exchangers to PRE-heat make-up-air back to the process or the building.
