Underfloor train air conditioning system ME7070

hermeticfor locomotivesdriver's cabin

Overview
The ME7070 is an underfloor-mounted HVAC unit designed for locomotive cabs, configured as an EMD-style sub-base. Microprocessor control with integrated soft-start and heater management reduces inrush stress on motors and locomotive power buss during startup. A three-hour timer and internal thermostats provide automatic protection and anti-icing/heater-overheat prevention, enabling long service intervals and dependable operation in rail environments.

Key features

• 30,000 BTUH cooling capacity in 2 stages
• 11.25 kW heating capacity in 3 stages
• 2-stage blower-only operation with high-performance blower
• Hermetically sealed scroll compressor
• Microprocessor control with built-in soft-start and heater control
• Three-hour automatic shutdown timer for unoccupied cab
• Internal thermostats to prevent icing and heater-coil overheating
• Built-in overload protection and safety controls
