So-Low | Explosion-Proof Upright Manual Defrost Freezers

So-Low | Explosion-Proof Upright Manual Defrost Freezers for Hazardous Locations | -18°C to -25°C Laboratory & Industrial Cold Storage

At Alto Med Supply, we offer So-Low explosion-proof upright manual defrost freezers designed for safe, reliable cold storage in hazardous laboratory and industrial environments.

Built to meet NFPA and OSHA requirements for Class I, Division II, Group C and D locations, these units are ideal for storing volatile or flammable materials with confidence.

For enhanced safety, critical components such as the compressor and thermostat are enclosed in vapor-proof housings, and each freezer is hardwired directly into your facility’s electrical system to reduce the risks associated with standard plug connections.

These laboratory-grade upright freezers are available in sizes ranging from 14 to 30 cubic feet and maintain a consistent temperature range of -18°C to -25°C, making them suitable for sensitive samples and regulated materials.

A single solid locking door adds an extra layer of security, while high-density, CFC-free polyurethane insulation helps ensure excellent thermal efficiency.

The manual defrost design minimizes temperature fluctuations often caused by automatic defrost cycles, supporting stable internal conditions and dependable performance.

As a trusted online retailer, Alto Med Supply provides these high-performance So-Low freezers as a dependable solution for facilities that prioritize safety, compliance, and consistent cold storage.
