Engineering FAQ

Free, auditable, site-laptop safe.

Free, no sign-up, formulas shown — the same tools our ShivOlive™ pump and water-treatment engineers run on live ETP/STP/RO projects.

Every calculator exposes the formula and the intermediate values — auditable engineering you can defend in a design review, not a black box.

Each runs entirely in your browser once loaded — no data leaves the machine, so they are safe on air-gapped site laptops and plant floors.

The TolsTek Group's water-treatment and industrial engineering line — these calculators are the field tools from real plant projects, hosted by RetailDA™.

The same maths runs automatically inside the Industrial IoT stack — dosing, flow, energy and pump telemetry feed the ledger directly. Water-treatment deployments →
