Ag-Tech Innovation: Precision Nutrient Delivery for Indoor Farming
As controlled-environment agriculture continues to expand, reliable and precise nutrient delivery systems are critical to maximizing crop yield, consistency, and operational efficiency. Sigma Design partnered with a leading global food and beverage company to develop a custom nutrient injection and fluid handling system for a next-generation indoor hydroponic farming facility.
Leveraging decades of experience designing complex fluid handling systems across multiple industries, Sigma engineered a fully integrated nutrient dosing skid tailored to the customer’s facility requirements and operational goals. The system was designed to deliver precise nutrient concentrations while maintaining consistent water quality throughout the growing process.
Working closely with the customer, Sigma evaluated and optimized the proposed equipment architecture, selecting pumps and system components best suited for long-term performance, reliability, and maintainability. The resulting solution combined robust engineering, efficient packaging, and scalable design principles to support future growth in the rapidly evolving indoor agriculture sector.
From concept through fabrication and testing, Sigma provided a turnkey engineering solution that helped accelerate deployment while reducing technical risk.

Sigma develops fluid handling and nutrient injection system for the dynamic indoor farming industry
Sigma Design collaborated with a multinational food and beverage giant to develop a nutrient dosing system for their newly developed indoor hydroponic agriculture farm. We used our extensive background with fluid handling systems across many industries to perfect a water and nutrient dosing system in a well packaged and well engineered skid to fit their final dimensional layout required at their facilities. Pumps were selected after Sigma Design did a review of components suggested by our customer, and our background helped us optimize some components to better fit expected operating conditions.

Serving Safe Chicken: Meeting FDA Requirements for Safe Food Holding Temperatures
How much heat does it take to keep food safe for consumption? Sigma used its advanced engineering skills to answer this question. A New Jersey-based company asked Sigma to analyze their warming tray prototype by performing a heat power analysis and thermal FEA on the heater element and control circuit.
The tray is designed to keep rotisserie chickens at a safe internal temperature of 140°F and breakfast sandwiches at a slightly lower temperature, determined by a high and low setting that is set by an operator’s switch.
Step one was to determine the steady state heat power requirements to keep the chicken at temperature by using hand calculations. Then a simplified FEA was run to verify that it matched the hand calculations.
Step two was to source heater elements that match the power requirements found in the hand and FEA calculations from the previous steps. The final step was to determine a control circuit to keep the surface temperature of the plate as constant as possible, meeting the FDA requirements for safe holding temperatures.
