On-premise / SaaS Platform

What is LinkitDAHS®?

LinkitDAHS is a flexible Data Acquisition and Handling System (DAHS) that adapts to your company's needs. As a SaaS (Software as a Service) platform for environmental monitoring and regulatory compliance, it operates in a scalable, multi-site and 100% cloud-based manner. The solution optimizes the acquisition, management, validation (QA/QC) and traceability of data from Continuous Emission Monitoring Systems (CEMS), ensuring full compliance with current regulations at a lower operational cost. Drive your digital transformation by migrating from static systems to a hybrid edge architecture (on-premises Edge) that operates in perfect redundancy with SISEP's SaaS platform.

Automatic omni-channel acquisition

Continuous real-time data capture directly from gas analyzers, particulate matter, flow meters and CEMS peripherals. Centralizes critical variables without human intermediation, eliminating information gaps and ensuring data integrity from the source.

Advanced validation and rigorous QA/QC

Implements automated environmental quality control algorithms aligned with international and local standards. Manages data statuses (valid, invalid, calibration, maintenance) and executes substitutions of missing data with auditable end-to-end traceability.

Regulatory averages calculation and alerts

Automated processing of hourly, daily or monthly averages according to the specific requirements of each current legal framework. Generates inspection-ready reports with transparent mathematical traceability and incorporates early deviation alerts to actively prevent regulatory exceedances.

Certified online transmission (SMA/OEFA)

Native, secure interconnection with environmental enforcement platforms using the official protocols required by SMA (DNP3 and REST API) and OEFA Peru (REST API). Local edge storage (store and forward) ensures data delivery even during internet outages.

Environmental compliance

Designed for strict regulatory compliance

LinkitDAHS® centralizes and validates your plant's environmental information, ensuring complete traceability of measurements and events for regulatory audits. The system automates:

Continuous data acquisition: real-time capture without human intermediation.
Robust QA/QC validation: aligned with EPA 40 CFR Part 60 and Part 75 standards, SMA regulations in Chile and OEFA in Peru.
Regulatory average calculation: automated processing of averages per each legal framework.
Status and substitution management: intelligent handling of missing data with auditable traceability.
Native integration and transmission: direct online connection with environmental authority systems.

15-minute and hourly blocks: structured calculations per authority requirements.
Daily, weekly and monthly: periodic environmental behavior summaries.
Detailed quarterly: robust consolidations for corporate reporting.
Emissions and calibration reports: historical compliance records and analyzer status.
Substitution reports: supported evidence of data filling under official methodologies.
Green Taxes calculation: structured reporting for the annual tax declaration.

Buyer's Guide

3 relevant questions to compare a corporate DAHS with a conventional one

Our answers, backed by evidence, separate real engineering track record from mere advertising slogans.

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

Why ask: demand that the supplier provide a client, a plant and a concrete year. A "pioneer" claim without a verifiable installed base is just advertising.

LinkitDAHS® answers: we have operated multi-source online systems since 2020. Demonstrable cases: Cementos Melón (4 plants and 6 CEMS nationwide), ENGIE Energía (7 CEMS at the Mejillones-Tocopilla Complex), CBB (2 CEMS Southern Zone), Polpaico-BSA (2 CEMS Central Zone) and ENGIE Energía Peru (4 CEMS at Chilca Uno Complex). Today we manage more than 25 systems in Chile, 4 installations validated with OEFA in Peru, and 3 large corporate multi-source architectures with more than 15 active subsystems.

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

Why ask: online connectivity is not proven with laboratory simulations; it is validated with real transmissions accepted by SMA or OEFA. Requesting the official acknowledgement is the only way to separate providers that operate successfully from those that only announce it in their catalog.

LinkitDAHS® answers: our system includes a native audit and traceability module. It allows you to directly download the official receipts and acknowledgements issued by the authority, both for transmissions via DNP3 protocol (Res. Ex. 680/2021) and API (Res. Ex. 252/2020) in Chile, and through the PLUSD portal for OEFA in Peru (RM 201-2016-MINAM).

What international validation standards does your software implement and under which local regulations does it report?

Why ask: a robust, industrial DAHS must validate data integrity under internationally standardized methodologies and algorithms. If the supplier's answer is generic, ambiguous or does not cite specific regulations, the risk of legal observations or data rejection is critical.

LinkitDAHS® answers: the calculation engine executes QA/QC validation algorithms strictly aligned with the global standards EPA 40 CFR Part 60 and Part 75. This ensures full compliance with the enforcement criteria of SMA in Chile and OEFA in Peru (complying with D.S. 030-2021-MINAM and R.M. 201-2016-MINAM), automating validation rules, data status marking, official substitutions and regulatory averages with end-to-end auditable mathematical traceability.

Innovation is not self-proclaimed: it is proven with correlative dates, current corporate contracts, high-demand operational clients and real in-plant engineering support.
