Mitsubishi CMR-M-KT Shut Off Valve Kit service details

The CMR‑M‑KT Shut‑Off Valve Kit is a safety accessory for CITY MULTI® VRF systems designed to help limit refrigerant migration in the event of a leak. Utilizing electronically controlled expansion valves installed on both the liquid and gas lines, the kit automatically isolates refrigerant flow when a connected sensor or external controller detects conditions that could lead to elevated room refrigerant concentration. By reducing active refrigerant volume during a leak event, the CMR‑M‑KT supports regulatory compliance while helping protect occupants and maintain safe system operation.
