The VRW system (Variable Refrigerant Water) was created to meet HVAC needs using water as the thermal transfer medium. VRW is an easy system to install and simple to operate that does not require specialized labor or high cost components. Among its main advantages are

• Options for mixing hydronic components of different brands.
• Minimal use of refrigerant in chillers units.
• Water as a heat transfer medium.
• Simple and agile changes in the location of terminals units by not using expensive copper tubing and skilled labor.
• R-410A eco-friendly refrigerant.
• Reduced health risks by not pumping refrigerant to terminal units or within the system.
• Significant savings in installation when using different materials to copper, such as PVC, hose flexible, thermoformed polypropylene.
• Water pumping is very simple and cheap, which maximizes system efficiency at lower cost. There is no loss of capacity in the terminal units regardless of their distance from the chiller.
• The variable system generates energy savings, that allows a return on investment.
• VRW allows to generate ice water when the energy electric is cheaper and store it for later use, generating extra savings via thermal storage.
• Allows the use of radiant heating and cooling.
• Hydronic components are simple to find and inexpensive.
• The modular design of the VRW system generates savings in the initial investment by allowing to add additional capacity on request.
• Simple, agile and economical maintenance without costly personnel and specialized labor.
• Open protocol for communications and control. It is not necessary to pay expensive annual licenses.
• The useful life of the components is extended, maximizing the initial investment.
