Maruzen Cold Storage Drastically Reduces Operating Costs by Installing Carlisle Controls & EC Motors
Maruzen Cold Storage, an international cargo and warehousing company based in Los Angeles, California, operates a 150,000 sq. ft. refrigerated facility specializing in agricultural products. With 16 independently controlled cold rooms, precise temperature and humidity control are essential to their business operations.
The Problem
Running evaporator fan motors 24/7, 365 days a year led to massive energy expenses. With energy costs continuing to rise—expected to increase by 40% over the next five years—Maruzen needed a reliable and cost-effective solution to reduce operating expenses while maintaining strict cold storage requirements.
The Solution
Carlisle Energy partnered with EnerNOC to conduct a full savings analysis. The retrofit included upgrading 39 evaporator coils with Carlisle Controllers and 98 EC Motors ranging from ½ to 2.0 HP.
- Projected 5-Year Savings: $766,225.20
- Utility Incentive from SCE: $67,999
- Return on Investment (ROI): Less than 13 months
This upgrade immediately reduced Maruzen’s energy consumption while ensuring their facility could meet rigorous operational demands.
Why Carlisle Energy Was the Right Choice
Carlisle ECM Controllers sense the cooling system’s operational status and intelligently adjust evaporator fan speeds. Fans operate at low speed when cooling isn’t required, circulating 40% as much air but using just 10% of the energy.
Adding Carlisle Controllers alongside EC Motors boosts efficiency by up to 50% more savings compared to EC motors alone—making it one of the most effective energy solutions for cold storage facilities.
