​Yanmar HydroBox

VRF Technology - Air-To-Water Integration Kit

Boilers & The Move To Decarbonization

Maximizing efficiency and comfort, year-round for all hydronic systems. Lowering the buildings carbon foot-print and operational costs while increasing the efficiency and energy output of today's inefficient boilers!

The Yanmar Hydrobox delivers chilled water or hot water using its powerful VRF heat exchanger, transferring the energy created by the Yanmar Gas heat pump towards any hydronic or boiler system.

• Simple and easy connection to any existing hydronic systems.
• Can be configured for heat only, cooling only or both climate controls.
• Complete with pump speed control in heating and cooling modes to meet outlet temperatures.

Yanmar Hydrobox Key Benefits

​As an air-to-water system, the Yanmar VRF gas engine heat pump is positioned outside of the building and connected via its refrigerant line-set directly to the Yanmar Hydrobox, located inside the building. Frost protection measures can thus be dispensed with.
 
With Yanmar’s Waste Heat Recovery Technology, excess heat is diverted for defrosting the registers without heating interruption to the building. Ideal in both new and retrofit hydronic residential, commercial as well as industrial applications. 

• Heat pump manager with Remote Display, optional Internet connection.
• Optimized plate heat exchanger with electronically controlled expansion valve.
• Energy Efficiency Pump
• Differential temperature control for circulation pump.
• Safety relays and safety module.
• Demand oriented temperature / 5-stage power control.
• Integrated heat management system (Heating, Cooling, Domestic hot water, etc.).

• Simultaneous heating and cooling with integrated heat recovery
• Power adjustment by means of modulating operation
• High efficiency due to use of condensing technology
• Lower operating costs compared to boilers and electric water chillers
• Low noise emissions, environmentally friendly
• Engine waste heat can be recovered and reused in cooling mode, allowing simultaneous cooling and heating, including domestic hot water heating (heat recovery optional)

• ​Cascadable up to the MW range
• No frost protection measures necessary for the lines between the gas engine heat pump (outdoor unit) and Hydrobox (indoor unit)
• Optionally, a complete input of parameters is possible via remote monitoring
• No heating interruption in defrost mode
