B-COOL X7RM | 12V & 24V DC Powered Air Conditioner with PTC Heating

The B-COOL X7RM is the only unit in the B-COOL lineup that both cools and heats — making it the go-to choice for operators who need 4-season climate control without idling the engine. Powered by 12V or 24V DC, it runs entirely off your battery system with no shore power, no generator, and no fuel burn. In cooling mode the X7RM delivers 400 m³/h of airflow — the same output as the 5RM but with the added capability of PTC electric heating, which warms the cab quickly and efficiently on cold mornings, during pre-trip warmups, or anywhere anti-idling regulations apply. At 48 lbs with the same 27.5 x 27.5 in rooftop footprint as the 5RM, the X7RM installs on the same roof cut and fits the same vehicles — giving you a direct upgrade path from cooling-only to full 4-season climate control.
