Thermaline Inc. is an innovative heat transfer solution provider for the food, beverage, and pharmaceutical industries. Processors worldwide have come to depend upon Thermaline’s quality product line, solid customer support, and practical industry knowledge to meet all of their heat transfer needs. Thermaline’s relentless pursuit of operational excellence is evident in every piece of equipment we manufacture. Our passion for this achievement ultimately gives our customers the competitive edge in their industry by providing intelligent, well-informed, and energy-conscious decisions in the equipment they purchase.


The heat exchanger surface is shaped into turbulence-inducing, alternating parallel grooves and ridges to increase heat transfer efficiency. Inducing turbulent flow results in less total surface area required to achieve the desired thermal results. Turbulent flow promotes thorough mixing of the product and even thermal disbursement without compromising product integrity.


Thermaline’s Floating Series tubular heat exchangers meet or exceed 3-A tubular heat exchanger design requirements.


The strategically-positioned elastomers eliminate the possibility of product intermixing. If a leak were to develop from an elastomer failure, the fluid would be vented to the atmosphere so it can be quickly identified and repaired. The Floating Series eliminates blind, internally-positioned elastomers that can lead to cross contamination.

The innovative design allows the tubes to freely expand and contract independently which diminishes material fatigue and failure. Thermaline’s Floating Series completely eliminates failure-prone expansion bellows and rigid welds on all models.

Operational Simplicity: 

The product flow and heating/cooling media flow are separated in concentric lengths of sanitary tubing. The unit has no moving parts, is easy to clean, easy to inspect, and easy to maintain. Tube ends, with their sanitary clamp design, can be easily removed for QC inspections and maintenance.

Go Green: 

Tubes can be arranged in either direct or indirect regeneration. Direct product regeneration can yield more than 80% in energy savings. Indirect product regeneration can recover energy from thermal waste streams in other areas of your facility, reducing thermal pollution and increasing energy savings.

Adding the DuoFloat inline mixer to your double-tube heat exchanger enables you to tune your processing needs to a variety of products. When processing fluids with large particulates, remove the DuoFloat inline mixer to maintain product integrity and then easily reinstall the mixers to ensure thorough heat transfer on your other viscous products.
