VRF Multi-Port Changeover Box (4 Ports)
The YORK® Multi-port Changeover Box (COB) is the workhorse in a heat recovery system, redirecting refrigerant vapor to the desired zone.
- Continuous operation eliminates risk of full system shutdown due to indoor unit malfunction
- Electronically controlled valves and fully insulated valve housing minimizes noise for quieter operation
- 4-port system is ideal for medium-sized areas that require heating or cooling at various temperature settings
With multiple ports already in place, you can anticipate reduced labor and material costs as future expansion arises.
Continuous operation reduces risk of system shutdown, even if one of the connected units malfunctions.
Precise indoor comfort is delivered based on zone demands. Electronically controlled valves and a fully insulated housing reduces sound.
