Sub-Zero Cold Storage Lifts

Premium Grade European Standard Lifetime Support

Experience unparalleled quality and innovation in elevator technology, designed for discerning clients who demand excellence in every detail.

Thermal Isolation Engineering

Sub-zero cold storage lifts are engineered to operate in temperatures as low as -40°C. Technically, this involves the use of specialized "Arctic-Grade" steel that remains ductile at low temperatures to prevent brittle fracture. All electrical cabling is insulated with silicone or PTFE to prevent cracking. The drive system utilizes low-viscosity synthetic oils for the gearboxes (if applicable) and specialized heaters for the motor and control cabinet. To prevent ice buildup on the guide rails and door mechanisms, the system includes integrated heating elements. The engineering also focuses on thermal seals for the doors to prevent warm air ingress into the cold storage zone, maintaining the energy efficiency of the facility.
