LDE – Low Profile – Double Side

The TRIDAN LOW-PROFILE Double-Sided Vertical Mechanical Expander, due to it extraordinary space saving features, mechanical precision and durability has become the standard design for vertical expanders used on medium and large size coils. Also, it allows the application of a vertical expander for many of the very large coils. Which horizontal expanders were formerly considered as the only practical approach, by reducing the required vertical headroom approximately Twenty-two (22%) percent.

Each TRIDAN Expander incorporates the design knowledge and also workmanship of an organization intimately aware of the particular needs of such equipment. In addition, since 1967 TRIDAN has so improved the level of performance of the Mechanical Expander that we now see our competitors emulating such original design innovations as:

* The Fully machined expander frame
* Full-Length adjustment screws
* Automatic work head clearance adjustment
* Quick setting air cushion height adjustment
* Individual power units for each expander side
* Quick change of expander rods from floor level with no tools
* Safety clamps on the length adjustment stop block assemblies


This Vertical Mechanical Expander is designed to incorporate the following production functions independently on each expander side:

A.) Simultaneous mechanical expansion of all the heat exchanger tubes to a precise internal diameter. Thus forming a secure mechanical bond between each tube, the complete finned core, and the end sheets.
B.) Sizing the coil to establish the final finned core length of the heat exchanger for the correct length dimension between end sheets.
C.) Automatic belling (or final sizing) of the tube extensions to a specific bell diameter and depth in relation to the coil end sheet. This tube extension belling operation provides for insertion clearance of the return bends and other brazed coil circuiting tubes.
D.) Each side of the machine can be different upon request.
