Sustainability Benefits of Eilersen Calibration Technology:

Cost and Environmental Savings Compared to Traditional WFI

Tired of the high costs and environmental impact associated with the consumption of Water for Injection (WFI) when calibrating weighing systems? Discover how Eilersen calibration technology, specifically the EilerCal™ system, offers a more sustainable and cost-effective solution for your pharmaceutical and biotech tank scale calibration needs.

The High Cost of Water for Injection (WFI)

WFI is essential in processes where sterility and cleanliness are critical, but it is expensive. The cost of WFI can range between 50 cents and 1 EUR[^1]. For example, filling a 50,000-liter vessel with WFI for calibration purposes can cost between EUR 25,000 and EUR 50,000. This cost is incurred every time the vessel is filled and calibrated. Furthermore, companies often perform two to three calibrations annually, leading to even greater expense, along with substantial water waste.

EilerCal ™ Technology: Significant Cost and Resource Savings

With Eilersen’s EilerCal technology, there is no need to fill large vessels with WFI for calibration. This alone offers an immediate cost saving of approx. EUR 50,000 [^1] per calibration for a 50,000-liter vessel. For companies conducting multiple calibrations, these savings can multiply, amounting to hundreds of thousands of euros annually.

Here’s how the estimated savings break down:

Cost of WFI per calibration: EUR 50,000 for 50,000 litres at EUR 1.00 per litre [^1].

Multiple calibrations: If two to three calibrations are performed annually, this results in potential annual savings of EUR 100,000 to EUR 150,000, just on WFI alone.

Environmental Benefits: Water and Energy Savings

Beyond the financial savings, the environmental benefits are significant. Traditional methods that rely on WFI not only wastewater, but also incur energy costs for the production, purification, and storage of such large volumes of water.

By eliminating the need for WFI in the calibration process, the EilerCal:

• Reduces water waste: The water used in calibration processes is often discarded after a single use, leading to significant waste. Eilersen’s technology drastically reduces this unnecessary consumption.
• Lower energy usage: Producing WFI requires substantial energy to ensure the water is pure and meets stringent pharmaceutical standards. Reducing WFI usage translates to lower energy consumption, further contributing to sustainability goals.
• Eliminate the need for tank cleaning: Even if using WFI to calibrate tank scales, a thorough sterilization of the tank (SIP) using steam or chemicals is required after the process is completed to prevent potential contaminants from interfering with the product. When using EilerCal, you don’t interfere with the tanks’ content, making cleaning unnecessary, thus saving time and resources.

Time Savings and Increased Efficiency

Eilersen’s EilerCal calibration technology not only saves money and resources but also enhances operational efficiency. The process of filling, calibrating, and then emptying large vessels can be time-consuming, sometimes taking several days. The EilerCal system allows for fast, accurate calibration without the need for manual intervention or filling vessels, significantly cutting down on labour hours. A large vessel can be calibrated in less than 45 minutes using the Eilercal system! A site engineer can be fully trained to use this system in less than 1 hour.

This means that operations can run more smoothly, with less downtime between calibrations, contributing to a more streamlined production process. For industries where time is money, this is a crucial advantage.

A Smart Investment in Sustainability

Adopting EilerCal technology is a smart investment for companies looking to reduce costs and environmental impact. The significant savings in WFI costs, combined with the environmental benefits of reducing water and energy waste, make this technology a leading solution for sustainability-conscious businesses.

Switching to Eilersen’s EilerCal can reduce the time required for calibration per annum and help companies reduce their operational expenses while contributing to a more sustainable, eco-friendly approach in an increasingly resource-conscious world.
