Challenge: In an ultra-low temperature environment of -40°C, equipment is prone to freezing and failure.
Solution: Use cold-resistant polymer idlers (with grease that remains fluid at -50°C) and explosion-proof electric drums.
Case: A certain pharmaceutical cold storage uses a customized electric drum (with a power of 1.5kW) and cooperates with sealed idlers. It operates continuously at -40°C, reducing the failure rate by 90% and decreasing the energy consumption by 35% compared with traditional equipment.
