01The core pillars
From math to model.
Mechanical design software for shell-and-tube heat exchangers, resting on two codes that engineers, fabricators, and inspectors know well.
TEMA Rigor
Follows the TEMA Class R, C, and B geometric and mechanical configurations.
TEMA: Tubular Exchanger Manufacturers Association.
02The workflow
One workflow, from process specification to mechanical fabrication.
An engineer often manually re-enters dozens of fields from the process datasheet into a mechanical model. It takes time, and each field is a chance for a transcription error. PlutoHX parses the datasheet directly, so there is no need to enter it again.
Step 01: Import
PlutoHX parses the input parameters straight from the process datasheet.
You approve the dataYou review and approve the imported data before any design is made.Step 02: Optimize
Changes to the design show in the model in real time.
Step 03: Design
Design to ASME and TEMA instantly, part by part, with checks as it goes.
Step 04: Report
The calculation package, drawings, and bill of materials, in PDF and Excel.

03Features
Precision engineering, made practical.
- PlutoGenAn AI assistant that parses the datasheet.
- Datasheet importProcess data imported, with no manual re-entry.
- 3D modelTurn it, open it up, cut it away.
- Flanges and boltingThree flange pairs, designed with the exchanger.
- TubesheetsThickness and layout, to Part UHX.
- Fabrication sequenceThe build, in eight stages.
- Error checkingLive checks against the code limits.
- Material libraryASME Section II materials, ready to apply.
- ReportsThe calculation package and its drawings.
04Compliance
Built on the codes engineers already work with.
ASME Section VIII, Division 1 for the design, TEMA for the construction, API 660 for the industry, and the standards around them.
05Use cases
For everyone who works on an exchanger.
FabricatorsBids from the customer’s datasheet, and a build plan.
Design engineersNew exchangers, and what-ifs that answer at once.
EPC firmsLate design changes, with the checks run again.
Owner-operatorsDesigns and records for the life of the exchanger.
Quality managersEach result traceable to its formula and rule.
StudentsLearn the codes on the Free plan.
06The Pluto family
One suite for mechanical design.
PlutoHX is the first of three products from Maltirra Solutions, for the oil and gas, petrochemical and power generation industries.
