Air-to-Air Dimple Plate Heat Exchangers
Leading air recovery technology
PRE-heat air-to-air dimple plate (DPL) heat exchangers have many consistently spaced dimples, which are ideal for bettering turbulence and managing low-pressure drops. The DPL unit is our most versatile, rugged, heavy-duty, yet cleanable plate heat exchanger. The DPL utilizes dimples on each plate to maintain plate spacing and enhance turbulence while operating at lower pressure drops. Our DPL is an all-welded plate-type heat exchanger with the most robust primary seal weld in the industry.

The dimple plate heat exchanger is versatile, rugged, and heavy-duty, yet cleanable. Variable plate thickness, plate spacing, plate sizes, and air-flow patterns are designed to meet system requirements and fine-tune the system to maximize efficiency and cost.
Our dimple plate heat exchangers are commonly seen in industries that incorporate chemical processing, food processing, automotive heater boxes, and furnaces. They can also be implemented in environments with corrosive atmospheres, wide temperature variations, high temperatures, and dusty air streams.
For low-temperature systems, aluminized steel or 409 stainless steel may be used. For corrosive or high-temperature applications, various grades of stainless steel alloys are used. Standard materials are 304, 326, 309, and 310 stainless steels.
PRE-heat is best known for our innovative, customizable heat exchange and recovery systems. Our systems are durable and robust, featuring all-metal, all-welded construction with variable arrangements and thickness.
