The environment matters in the food and beverage and pharmaceutical industries as products may have environmental production and storage requirements. Some larger plants have sensors that report environmental conditions to a central control that presents these readings to users and alerts them to out-of-tolerance conditions. This helps staff to respond to problems as they occur, but may not keep an easy-to-use record of conditions.

Grantek saw a need for a simpler version of these Building Automation Systems (BAS), so we created a BAS Lite called Guardian to meet the needs of product storage facilities where environmental monitoring is critical. It provides fault monitoring but does not provide the building controls included with a full BAS system. Guardian our BAS Lite is a smaller, more affordable way to monitor environmental conditions without also having to replace your existing HVAC controls.

Grantek also fully understands the regulatory environment in which your company operates and so designed and built a product capable of collecting and storing data from a facility’s environmental monitoring system to archive accurate records of environmental conditions.

Grantek’s Guardian, consists of calibratable environmental sensors that send data to a PLC, which collects it and sends it over the internet to a central repository for action (if needed) and archiving. Grantek’s Guardian has a Software-as-a-Service (SaaS) application component which we created to collect, archive, report, alert and alarm environmental conditions. Guardian is a Web-based system that utilizes onsite hardware to collect environmental data from sensors.

Guardian takes the place of older paper-based temperature and humidity recording equipment, which relies on human intervention to change the chart paper and properly store the daily charts. Why rely on a manual process when it can easily be replaced with automated data collection and reporting? Your plant maintenance staff will appreciate not having to change chart paper any longer.

Guardian can even be used for monitoring mobile equipment such as snowplows and refrigerated trailers equipped with GPS and it can be used to drive marquee displays in or outside of a facility to provide highly visible variable information to employees.

Guardian can accept a wide variety of inputs, including analog or digital, 4-20 mA temperature sensors, GPS, fire alarm systems, fan sensors, power monitoring signals, and weather station data.

Guardian also has an alerting function to notify designated email addresses, send SMS messages, or trigger telephone calls if a sensor input is out of bounds. Telephone alerts are sent to a call center and a human then places the call to the appropriate predefined contact.

Furthermore to ensure that data to the Guardian system is accurate, Grantek offers a yearly calibration exchange package, wherein a facility exchanges their sensors for newly-calibrated sensors on an annual basis. Grantek understands the requirements of a quality management system and helps customers comply by helping to ensure that the environmental sensors remain within calibration at all times.

Because Grantek designed and built Guardian, you are not dependent on 3rd parties to maintain it – it’s one less thing your company has to worry about. Our annual subscription fee includes support and  validation

The Guardian system can be configured to meet your enterprise’s specific needs. Guardian’s onsite hardware runs on an embedded Linux-based Communications Control Unit (CCU). This dedicated computer connects directly to the environmental monitoring system and accepts digital and analog inputs. Guardian was developed by Grantek from the ground-up to satisfy regulatory environmental requirements and so has a built-in audit trailing, to record access and changes by personnel.

Grantek built Guardian with security as a top priority. Data is encrypted and locked down. The data collection PLCs are password-protected, read-only, and firewalled to help prevent unauthorized access to the Guardian system.

As companies strive to operate as a seamless whole, environmental data is as important as any other data produced. It may be of utmost value in the event that an issue regarding how your product was produced or stored threatens a recall. Archiving your environmental data can save money and help protect the company’s reputation.
