NEW: ES MultiCore ULT

The ES MultiCore ULT delivers ultra-low-temperature storage through a durable cold-wall freezer farm architecture designed to protect biological samples, vaccines, research materials, and other temperature-sensitive products. 

As a more durable alternative to traditional freezer farms filled with standalone ULT freezers, the ES MultiCore ULT utilizes shared redundant mechanical skids that can be remote from the storage area. This helps remove heat and noise from the freezer environment, creating a quieter workspace, improving service access, and extending equipment life. By separating refrigeration systems from storage chambers, critical mechanical components are better protected and easier to maintain. 

Inventory protection is reinforced through 100% refrigeration redundancy, advanced controls, and predictive monitoring. This integrated design reduces the risk of product loss, supports continuous operation during maintenance events, and helps ensure long-term reliability for critical storage applications. 

To further protect inventory, it features OverShield® by Predictive Monitor for 24/7 visibility into critical components and system health. Combined with redundant refrigeration, OverShield® provides added confidence that valuable materials will remain protected when uninterrupted temperature performance matters most. 

The ES MultiCore ULT comes validation-ready to streamline qualification and compliance efforts in regulated environments, and its low GWP refrigerant supports sustainability initiatives and environmental goals.

The ES MultiCore ULT is suitable for a wide range of industries and applications, including:

  • Biorepositories 
  • Research institutions
  • Pharmaceutical manufacturers
  • Biotechnology
  • Life sciences

  • “Thanks again for the support in getting us to this stage eventually – finding an incubator that meets our temperature spec has been a challenge for us for the last few years and this is a significant milestone for the business. Hopefully we will have more good news to report in the new year.”

    Project Engineer, Major Biotechnology Manufacturer

  • “During a recent external audit, an inspector requested the PM/Cal documents for the stability chambers. It was my pleasure to give him the nicely presented binders. I could tell he was impressed.

    Thanks for the great service you have provided for us over the years.”

    Teresa P, Taste Texture and Health, DSM-Firmenich

  • “Environmental Specialties has always provided me with great service. All the individuals I worked with were knowledgeable about ES products and services.  They were highly skilled. I relied on ES for pm, calibration, qualification, repair, chamber sourcing and consultations. I interacted with a lot of your employees.  The feedback was always spot on. They were always smiling and supportive even in the most difficult situations. ES is a great company with good people.”
