3 questions to tell a real DAHS from a promise

Before believing any supplier that claims to be the "first" or "only" 100% online solution, ask these 3 questions. Evidence-based answers separate track record from slogans. SISEP answers them with facts.

1

Since what date and in which plant does your multi-source DAHS operate today?

Ask for a real client, plant and concrete year. A "pioneer" claim without a dated installed case is just a press release.

LinkitDAHS® answers: multi-source online since 2020 — Cementos Melón (7 CEMS, La Calera / Ventanas / Puerto Montt / Punta Arenas), and since 2019 at BSA. Today: 25+ systems in Chile, 4+ installations in Peru (OEFA) and 3 multi-source systems with 15+ subsystems.
2

Can I see a report you already sent to the authority, with acknowledgement?

Online connectivity is only proven by real transmissions to SMA or OEFA. Asking for the acknowledgement separates those who report from those who only announce.

LinkitDAHS® answers: online reporting to SMA via RE680 since 2019/2020 (BSA, Melón, CCU, MASISA, ENGIE) and to OEFA Peru via the Plusd portal since March 2024, with official acknowledgements.
3

What validation standards did you implement and against which regulation do you report?

A serious DAHS validates against concrete standards. If the answer is generic or mentions no regulation, be wary.

LinkitDAHS® answers: QA/QC validation aligned with EPA 40 CFR Part 60 and Part 75, SMA compliance in Chile and OEFA in Peru (including D.S. 030-2021-MINAM, R.M. 201-2016), with validation rules, regulatory averages and full traceability.

Innovation is not self-proclaimed: it is proven with dates, clients and acknowledgements.
