# Master Engineering Technology

> Free browser-based engineering calculators and reference tools for rotating equipment, process, mechanical and project engineers: compressor, pump and motor sizing, bearing and lubricant selection, vibration limits (ISO/API), steam tables, heat exchangers, pressure vessels and more. No installs.

Tools run entirely in the browser; results are for estimating and reference and must be verified against applicable codes and project data before design use.
