Coolright 4 in 1

Coolright 4 in 1

4-in-1 air conditioner with inverter technology without external unit: cool, heat, ventilate and dehumidify with only one device

Discreet on the outside, functional on the inside

With this powerful wall-mounted solution, staying indoors has never been more comfortable on hot summer days. With inverter driven heat pump technology we also recommend the Coolright 4 in 1 as a cost-effective additional heating system for winter.

Installation can be completed on any exterior wall; brick, block, timer or modular within a few hours - dramatically reducing labour time on site whilst being less invasive and without the need for an external heat exchanger unit.

The Coolright 4 in 1 can be placed either as a chest unit (above the floor) or as a wall unit (on the wall / under the

Coolright 4 in 1: 2.6kW Cooling, 2kW Heating, 1.2l/h Dehumidification, 500m³/h Ventilation – all without an external unit

The Coolright 4 in 1 Smart Air Conditioner does not require an external unit. Only two holes (∅ 18 cm) are needed for the air inlet and outlet ducts allowing fresh air to enter the room and rejecting the heat transported from the inside to the outside.

The Coolright 4 in 1 Smart Air Conditioner eliminates the need for an external unit. Only two holes (∅ 18 cm) need be drilled for the air inlet and outlet ducts allowing fresh air to enter the room and the heat to be rejected outside. No external refrigeration circuit makes installation fast and easy.

Advantages of an air conditioner without external unit and exhaust air hose:

  • The air conditioner can also be installed on any floor, as the installation is done from inside (no installation of an external unit required)
  • Cheaper than a remote external unit
  • Can simply be plugged into a socket
  • No unsightly and noisy external unit on the facade
  • No half-open window (for the exhaust air hose) through which warm air flows in
  • Lower noise emission compared to air conditioners with exhaust air hose
  • No expensive installation by air conditioning installers
  • No maintenance costs

R290 environmentally friendly refrigerant

Synthetic refrigerants are responsible every year for several million tons of harmful CO2 emissions. The use where possible of LOW GWP refrigerants is one of our core values. By using R290 (propane) as refrigerant the GWP is less than 3!

The natural refrigerant R290 is an organic compound belonging to the group of hydrocarbons. Unlike synthetic refrigerants R290 comes with neither ozone depletion potential (ODP = 0) nor a noteworthy greenhouse effect (GWP = 3).

Additional bonus for the environment:  Owing to its excellent thermodynamic properties, propane (R290) is a particularly energy-efficient refrigerant thereby additionally reducing your energy costs.

Save energy while cooling or heating without external

Air conditioner for permanent installation without external unit and exhaust air hose – save yourself the purchase of several individual devices to provide cooling in the hot summer and cosy additional warmth in the cool autumn and winter. The Coolright 4 in 1 is puts energy efficiency at its heart thanks to inverter technology, combining four climate functions directly in 1 unit. At 20 cm deep, its slim line housing to creates a pleasant indoor climate all year round. Compressors with inverter technology boast around 30% lower power consumption than standard compressors and they are quieter in operation – perfect for domestic and light commercial settings. Its soft starting means the unit always adapts to the current conditions dynamically and with the aide of the Smart controls.

Four operating modes for a pleasant climate:

  • Cooling with inverter technology (energy efficiency category A)
  • Heating with energy-saving heat pump technology (energy efficiency category A+)
  • Ventilation with 3 fan stages
  • Dehumidification with a dehumidification performance of 1.2 l/h

Special highlight: In all 4 operating modes, the swing function can be activated for optimum air distribution in the room. To filter out fluff, dust and animal hair from the breathing air as well, an easy-to-clean air filter is located on the top of the device.

Enjoy draught-free cooling: The air conditioner has 2 hose lines that feed fresh air into the room from the outside and discharge warm air to the outside. When the outside air is still cool in the morning and evening, the outside air is directed into the room, which increases the cooling effect and saves energy. In addition, since no negative pressure is created in the room by the fresh air supplied from outside, there is also no unpleasant draught caused by air flowing in from neighboring rooms.

Inverter technology saving up to 30 % of power

Conventional air conditioners, which have been designed exclusively for cooling the room, work based on the on/off principle. The integrated cooling compressor reduces the room temperature at full load until the target temperature is reached. Then the compressor switches off. If it becomes too hot in the room, the compressor switches on again to reduce the room temperature again with full power. This consumes a lot of energy.

Inverter air conditioners like the Coolright 4-1 regulate the room temperature without the cooling compressor switching on and off. This helps to keep the room temperature at a constant level without fluctuations. The compressor consumes electricity continuously, but it never runs at full load. This prevents damage to the system. Additionally, due to the consistently low power consumption, inverter air conditioners also cool very energy-efficiently and save up to 30 % of energy compared to conventional products.

Mobile app for control via smartphone or tablet from anywhere

All settings of the Coolright 4 in 1 can be made either via the convenient IR remote control or the mobile app. Coming home early and longing for a cool-down? No problem – simply activate the air conditioner via your smartphone or tablet while on the move. You can call up the current room temperature, set the desired temperature, activate cooling or heating – and much more. The smart air conditioning control automatically regulates the temperature, cools down the room even before you get home and switches off automatically when you leave the house. In addition, you can also adjust the temperature remotely.

Wi-Fi integration with convenient smartphone control

Ordinary remote controls have a habit of getting lost when you need them… It’s good to know that you don’t actually need the remote control of the air conditioner Coolright 4 in 1. The unit can be easily integrated into your WiFi network via the Mobile app available online and then controlled via smartphone or tablet. Even while on the move or on the other side of the world! Controlled by you on your device!

Whether in spring, summer, autumn or winter – the Coolright 4 in 1 lets you enjoy pleasant indoor temperatures all year round. While saving energy and without
expensive installation work!
