VRF Multi-Port Changeover Box (4 Ports)
208/230V
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
Design Flexibility Now and in the Future
Easily accommodate future expansion with YORK® 4-Port Heat Recovery Changeover Box options. The 4-port design is ideal for medium-sized areas that require various temperature settings. Continuous operation between heating and cooling efficiently recovers and transfers refrigerant vapor based on the demands of the area.
Connect the indoor systems you need now and stay poised for growth. With available ports already in place, you can anticipate reduced labor and material costs in the future.

Benefits

DYNAMIC DESIGN
With multiple ports already in place, you can anticipate reduced labor and material costs as future expansion arises.

EXCEPTIONAL RELIABILITY
Continuous operation reduces risk of system shutdown, even if one of the connected units malfunctions.

UNMATCHED PERFORMANCE
Precise indoor comfort is delivered based on zone demands. Electronically controlled valves and a fully insulated housing reduces sound.
Features
- 4-port layout provides design flexibility and easily accommodates future expansion without added labor or material costs
- Fine mesh strainers protect valves and further increase reliability
- System operates using vapor instead of liquid, reducing number of valves required for increased simplicity
- Reliability optimized through continuous operation, so malfunction among connected units will not result in system shutdown
- Electronically controlled valves and fully insulated housing minimize noise and provide greater installation flexibility
- Simplified design provides easy service access to valves
