Packed with advanced technology, VRV IV X is the industry's first 3-phase variable refrigerant flow system with dual-fuel capability. The new series is equipped with features to optimize initial capital required on phased installations and provides ease of service and maintenance.
- VRV with Variable Refrigerant Temperature (VRT) technology
- Industry’s first 3-phase variable refrigerant flow system to integrate with communicating gas furnaces
- Design flexibility to enlarge system from single to dual module or dual to triple module without change to installed main pipe sizes – refer to the VRV IV X engineering manual for details
- Capacity range from 6 to 38 tons
- 208-230V / 3ph / 60Hz (REYQ_XBTJA)
- 460V / 3ph / 60Hz (REYQ_XBYDA)
- 575V / 3ph / 60Hz (REYQ_TBYCA)
