alternative to traditional centralized equipment. The VRV-WII is used extensively
worldwide in skyscrapers where the use of a cooling tower and boiler are necessary. Its
remarkable compact and lightweight structure makes installation of VRV technology in
large buildings possible. At only 330 lbs. and less than 40” high, the VRV-WII can take a
ride up the elevator to be installed in a machine room. It is a perfect fit for hotels and
conference facilities, offices and universities, especially in urban-packed areas.
A water loop is necessary between the VRV-WII condensing units installed and a
cooling tower and/or boiler.
The VRV-WII design is based on a “modular design” concept. It is composed of unified
condensing units that require simply to connect a 2-Pipe Refrigerant Network for Heat
Pump Applications or a 3-Pipe for Heat Recovery Applications. All Water Cooled
Condensers are in the same cabinet, but are available in a variety of capacities (5-Ton,
6-Ton & 7-Ton). A simple system that allows manifolding together up to 3 Condensers
to form one system of 21-Ton (252MBH). The condensers are designed for Internal
mounting only.
Why selecting a VRV-WII system? The top 4 reasons that make the solution a perfect fit
1.The efficiency and capacity of air cooled systems reduces with extreme ambient
conditions causing systems to be oversized and increasing first cost.
2.Extreme piping lengths cause a capacity reduction; positioning VRV-WII floor by floor
can reduce the capacity reduction and improve the efficiency of the system. Also, long
piping lengths cause a capacity reduction, positioning VRV-WII floor by floor can reduce
the capacity reduction and improve the efficiency of the system
3.Utilizing an existing condenser loop and associated heat rejection/injection will
reduce first cost
4.Where the building has diverse loads and energy can be recovered through the VRV-
WII system and/or the water loop
