Model DTL Series - Heat Exchangers

• Tube side flow is split between tubes to reduce the head loss.
• Shell side flow is directed across the tubes by baffles and results in significant increases in thermal performance. Cross flow also reduces fouling.

• Shell-and-tube heat exchangers are constructed with off-the-shelf components making them easy to manufacture and economical.
• All copper construction means the heat exchanger is compatible with existing copper plumbing.
• More than one heat exchanger can be used in a parallel or series arrangement to meet special heat transfer or physical requirements.
• High thermal performance, even with fouled heat transfer fluids.

• Ports and endplates are brazed. End caps are soldered with 95/5 tin/antimony.
• All heat exchangers are pressure tested to 500 kPa (75 psi) on the shell side and 1000 kPa (150 psi) on the tube side prior to shipping to ensure leak free operation for the customer.

• Low Working Pressure, up to 400 kPa (60 psi) domestic hot water boiler.
• Commercial, swimming pool and domestic solar water heating systems.
• Virtually all low/medium pressure applications where the fluids and existing plumbing are compatible with copper.
• Most of our shell-and-tube heat exchangers can be used in a thermosiphoning arrangement with forced circulation on the shell side.

For small heat transfer loads, 2 to 6 kW (6 to 20 MBtu/h), a coil-in-shell heat exchanger may be required, especially when a compact heat exchanger is required. The coil-in-shell is specifically designed for thermsiphon applications and can often be physically half the size of a shell-and-tube heat exchanger with equal thermal performance.

Thermo Dynamics manufactures all shell-and-tube heat exchangers in house and all are engineered and fabricated to strict tolerances. We pride ourselves on consistent quality control over manufacturing.

A single Thermo Dynamics shell-and-tube heat exchanger is capable of transferring from 2 to 120 kW (6 to 400 MBtu). More than one heat exchanger can be used to meet larger heat transfer loads. Nominal shell diameters are from 2, 3 and 4 inches.
The shell-and-tube heat exchanger features all copper construction. High pressure heat exchangers or stainless steel construction is available by special order only.Copper heat exchangers can be supplied with sweated or threaded ports for convenient plumbing.
