Distribute
Manifolds and seals keep the two fluid paths separate.
Corrosion-Resistant Low-Grade Heat Transfer
Polymeric Heat
exchangersThermoSnare™ is Trevi's field-tested polymeric tube-in-shell heat exchanger for low-level heat recovery, built for the acidic streams of industry and mining. One fluid runs through thin polymer tubes, one through the shell; capacity grows modularly.

Two Fluid Paths, One Thermal Interface
Polymer conducts less heat than metal. The design compensates: ultra-thin walls, high surface area, countercurrent geometry, controlled flow distribution.
Exchange
Thin polymer walls and surface area move heat between the circuits.
Recover
Geometry and controls manage duty, viscosity, temperature approach, and pressure drop.
- Wall
- Thickness · high and low pH compatibility
- Bundle
- Surface area · twisted or wound geometry forcing countercurrent flow
- Hydraulics
- Flow distribution · pressure drop · mixed hydraulic diameters
- Integrity
- Manifolds · seals · cleaning · fluids up to 130 °C and harsh chemistry
Pressure rating, service life, and cost are established for each project's fluids and duty.

Starting From the Heat Balance
A review starts with measured conditions and ends with a test plan.
- 01
Characterize the source
Record fluid, temperatures, flow, pressure, chemistry, fouling potential, and duty cycle.
- 02
Define the sink
Set the receiving fluid, target temperature, schedule, and required duty.
- 03
Engineer the boundary
Size the wall, bundle, manifolds, seals, and controls.
- 04
Validate the cases
Check startup, turndown, upset, shutdown, and seasonal conditions.
