4TON EVI air-to-water heat pump


EXINDA air-to-water heat pumps are designed to meet current and future regulations for energy efficiency. Thanks to the compressor with DC Inverter technology, they offer a heating temperature of up to 65°C

  • Low carbon footprint Refrigerant R32 (GWP=675) helps protect the environment and preserve HFC quotas.
  • Stable operating condition High leaving water temperature of max, 65°C or 60°C @ -15°C outside air temperature.
  • Powerful performance With high efficiency: Energy class A+++ (35°C) or A++ (55°C) ensuring high heating power at less energy consumption.
  • Cascaded system Multiple units (up to 6) can be linked together to efficiently meet the peak heat demand.

Enhanced Vapour Injection

  • EVI technology allows our air-to-water heat pumps to maintain high efficiency and capacity down to -13F air temperatures, means less reliance on all electric and gas backup sources.
  • With captures energy from the air, saving up to 40% when compared with traditional heating and cooling systems
  • The EVI ATW Heat Pumps can provide the solution for your retro-fit or new high efficiency comfort system.

Hydronic Heating & Cooling

  • The monobloc air-to-water heat pump is designed for heating and cooling applications in new and existing individual homes and small businesses.
  • It is able to produce hot water ∼60 °C at an outdoor temperature of up to 35 °C for domestic hot water applications.
  • The range is compatible with low to medium temperature emitters (underfloor heating, fan coil units, water cassettes, radiators, mixed installations, etc)

24V dry contact solution

With 24V dry contact or Modbus(RS485)
Interface, Exinda Integrate Heat Pump
can be connected to other energy source
such as fuel boiler, solar water heater, pelletboiler to achieve energy saving, based on local energy policy and user's preference.


It will be greatly helpful in extremely
cold area in Hybrid Heating System

Cascade Control System

Multiple units can be linked together to efficiently meet the peak heat demand.

  • Maximum 6 units controlled by one controller
  • Modbus and network flexibility
  • Well-documented interface such as RS485.

APP Remote Control

With DTU Module and Electric Wi-Fi, you can pre-heat or cool a room no matter where you are. Users are able to remotely set water temperature and room temperature, change mode settings and check real-time or historical running status via computers (WEB) or mobile phone (APP).

Environmentally Friendly

Heating & cooling with inverter air to water heat pumps Carbon Free Hydronic heat pump system. Instead of using a fossil fueled boiler as its heat source, you can cut out carbon by using an air-to-water heat pump.
