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.

Clima-Flex specializes in design and manufacturing of modular chillers that meet the needs of our customers and the market with a fresh and modern contribution


The Clima-Flex modular units were designed to mate with each other and be combined to meet any capacity need. If he project requires increased capacity, extra modules can be easily added to the system. The Clima-Flex chillers can work independently or in a tandem installation.


At the time of maintenance or if a fault occurs, modular equipment allows for redundancy, that is, when a module is put in standby mode, the system will continue to operate regularly allowing maintenance or overhaul of equipment, so the system will continue working without affecting its operation.

Energy Savings

Units based on quality and technology vanguard provides a high return on investment and a reduction in costs. Being a modular system, it only uses the necessary energy. On startup, the tandem operates with a single module, and as demand increases the other modules are enabled individually, likewise the tandem will decrease its operating demand when the building is partially vacant, thus saving energy.

Easy Installation

Our units have been designed for easy installation. The Victaulic connections allow for a rapid installation of the water pipes. The water connections are located on both sides of the units, in this way the pipes can be connected on either side of the system. Additional units can be added later on, reducing initial installation cost. All our units have a rigid base that balances the weight and allows easy installation.
