Helmer Scientific offers the only medical-grade pass-thru refrigerator with i.Lock™ interlock door technology, which supports recommendations for USP <797> compliance while ensuring the safe storage and efficacy of temperature-sensitive medications.

Company Background
Helmer Scientific, part of Life Science Solutions, a business unit of Trane Technologies, is a U.S.-based manufacturer and worldwide distributor of medical-grade cold storage and laboratory processing equipment. With over 45 years of experience in providing high-quality temperature controlled equipment, Helmer products are used by clinicians and facilities in more than 125 countries. Precise temperature performance and control are essential to the successful storage of pharmaceuticals, and Helmer cold storage products are designed and developed to deliver these results.

Product Overview
Pass-thru refrigerators play a key role in providing workflow efficiency and regulatory compliance in clinical pharmacies, sterile compounding rooms, and infusion suites.

Best practices recommend using purpose-built or pharmacy-grade units with forced-air circulation, microprocessor-based controls, and alarms, as well as necessary regulatory and compliance requirements based on application.

GX Solutions Pass-Thru Refrigerators are the only medical-grade pass-through refrigerators that include innovative technology to support environmental sustainability standards and evolving regulatory requirements while maintaining the unique temperature performance requirements required in pass-through refrigerator applications to reduce the risk of damaging valuable medications and vaccines.

GX Solutions support the specialty pharmacy with enhanced workflow efficiency, allowing entry from both sides of the unit for more convenient access to stored products. This is particularly useful when increased efficiency is desired when transferring contents between locations, especially in sterile compounding environments where direct room access should be limited.

OptiCool™ Refrigeration Technology
GX Solutions are powered by OptiCool™ technology which pairs a variable capacity compressor (VCC) and natural refrigerants to:
• Ensure optimal temperature uniformity, recovery, and stability.
• Efficiently manage energy consumption (up to 50% reduction over traditional medical-grade pass-thru units).
• Reduce noise output from the system.
• Meet SNAP, GWP, and EU F-Gas initiatives for sustainability.

Enhanced Performance Requirements
In addition to Accelerated Life Testing, GX Solutions Pass-Thru Refrigerators also undergo heavy-use testing to ensure they meet the rigorous daily use cases in the pharmacy. This includes testing ambient temperature loads, frequent door openings, and extended door openings to ensure temperature performance is not compromised while avoiding nuisance alarms.

USP <797> Sterile Compounding Pharmacy Support
GX Solutions Pass-Thru Refrigerators support updated compliance requirements related to USP General Chapter <797>.
• Pass-thru refrigerators used in cleanroom applications must be able to prevent cleanroom-side and anteroom-side doors from being opened simultaneously.
• USP recommends the use of interlocking technology on pass-thru equipment used in USP <797> cleanrooms.
GX Solutions Pass-Thru Refrigerators are the only pass-thru refrigerators available with optional i.Lock™ interlock door technology which electronically locks doors on one side of the unit when the other side is opened. This is especially useful when placed between a cleanroom and an anteroom, limiting access to sterile environments.
