Safety
Shutdown by fire alarm sensor
Automatic shutdown of equipment is configured by the fire alarm sensor in order to increase safety.
Refractory construction
The refractory design of the electrical box of the indoor unit has a modern, safe design that can resist the effects of open fire. In the event of a short circuit or spark in the electrical components of the unit, the flame will not go beyond the limits of the electrical box and will not cause a fire.
Correct and trouble-free operation of the chiller
High-performance chillers have 2 to 4 independent refrigeration circuits. They installed no more than 3 scroll compressors. This solution guarantees the correct and uninterrupted operation of the chiller in a wide range of loads and environmental conditions. At the same time, it ensures the preservation of working capacity from 50 to 75% in emergency situations.
Double-walled heat exchanger
The heat pump condenser is a heat exchanger «pipe in pipe» with double walls, which completely eliminates refrigerant leakage.
Installation Security
Automatic detection of address codes and automatic debugging simplify the installation process, reduce the risk of possible errors and increase operational safety.
Surge Protection
Stable operation of ROVER multizone systems is guaranteed even with significant voltage fluctuations (from 320 to 460 V). In the event of failure of one outdoor unit (with a modular layout), compressor or fan, the system may continue to operate in emergency mode. It is also possible to manually turn off the cooling mode in winter or the heating mode in summer to avoid errors due to a conflict of modes.
Construction safety
The standard seal between the frame and the ROVER central air conditioner panels is with self-adhesive rubber gaskets. Special rubber gaskets are available in outdoor equipment.
Aluminum alloy roof for outdoor installations protects against atmospheric precipitation. The joints of the roofs of the modules are closed with protective covers. This ensures impermeability to moisture and dust.
All materials and coatings of the internal parts of the air conditioner can eliminate the accumulation of static electricity on their surfaces. The internal cavities of the air conditioner are smooth. They have a minimum number of protrusions and cavities that contribute to the accumulation of various contaminants.

Low temperature operation
Cooling at low outside temperatures
ROVER conditioners reliably cool at a temperature of -15 ° C. The compressor performance and the fan speed of the outdoor unit vary according to how the outdoor temperature changes.
Air heating at freezing temperatures outside
ROVER conditioners perfectly heats air at street temperature to -15 ° C. Preheating and changing compressor performance ensure high-quality operation in the heating function.
Operation at low ambient temperatures
ROVER chillers have a “unloading” function, which allows you to keep the chiller working under conditions outside the operating range. They can also be equipped with a factory kit that provides operation at outdoor temperatures up to -30 ° C.

Energy saving
DC inverter
The technology of the DC-inverter motor allows smooth control of the rotation speed in the range of 5-65 Hz. It provides noise and vibration reduction and stable operation.
Maximizing torque with a minimum operating current reduces energy loss in the motor winding in order to increase efficiency.
Low-frequency control allows you to precisely control the torque of the electric motor. This allows the fan motor to work at a lower speed. Users will feel more comfortable, while the requirements of the system are also satisfied.
Intelligent defrost
The ROVER Intelligent Defrost program activates the defrost process on its own when the heat exchanger is freezing only. Defrosting ends automatically when freezing is eliminated. Energy consumption is significantly reduced for this reason, and the consumer gets maximum comfort.
Energy-saving modes of multi-zone systems
ROVER multizone systems provide two energy-saving modes:
- Automatic control of system operation parameters in accordance with the current room temperature. Electricity costs are reduced by 15%;
- Forced limitation of the power consumption of the block. Electricity costs are reduced by 20%.
Automatic energy distribution of multi-zone systems
Automatic distribution of energy occurs in a certain way with a modular layout. Upon reaching a productivity of 75% (of the nominal capacity of the unit), another unit is included in the work. One unit is automatically turned off in the event of a decrease in performance to 40%. This allows the operation of each unit in the range of 40-75% of the total load. This contributes to the lowest energy consumption.
Precise temperature control in multi-zone systems
High efficiency and energy savings are also achieved by temperature control. The limit on the set temperature is set when regulating the temperature. Reduced energy consumption occurs due to temperature regulation in a narrower range.
Efficient load balancing
Automatic uniform load distribution is organized between outdoor units for systems with a modular layout. This ensures lower energy consumption and longer equipment life.
Freecooling system
The Freecooling system installed in the chillers allows you to use natural cold to cool the water. The free cooling system includes water heat exchangers installed in front of the condensers, hydraulic connections and valves controlled by the chiller controller to distribute the flow of the cooled liquid. The liquid is cooled by external air that passes through a radiator with the liquid being cooled. Air is blown through it by axial fans, which cools the liquid inside the radiator. The Freecooling system can significantly save energy consumption for liquid cooling and increase equipment life. The payback period of a chiller with a freecooling system is 1.5-2 years for industrial use and up to 4-5 years for a comfortable use of the chiller.

Silence
Modern technologies used in the manufacture of ROVER equipment allow the creation of domestic and industrial air conditioners of the highest quality. At the same time, great importance is attached to such a characteristic as the noise level emitted by the equipment during operation. Therefore, all models are tested in anechoic chambers.
The walls and ceiling of anechoic chambers are lined with absorbent material for shielding from high-frequency interference. They do not reflect sound from the walls, they are also isolated from external acoustic signals. This eliminates reflection from the walls and noise from outside when measuring the signal that came directly from the air conditioner located in the free space.

Wide opportunities
Cooling system
Three components ensure uninterrupted operation of the ROVER air conditioning cooling system. These components are a stably running compressor, a heat exchanger with an improved pipe system and an electronic expansion valve that precisely controls the flow of refrigerant.
Corrosion resistant equipment
Air condenser heat exchangers are easily accessible and safe to maintain. They can be made in several corrosion-resistant versions, such as: copper coating, epoxy coating, which allows you to install chillers in adverse regions.
The fins of the heat exchangers of the outdoor and indoor units are made of an alloy of aluminum with manganese. They also have a protective gold coating and an additional hydrophilic coating. All this increases corrosion resistance.
Hermetic scroll and semi-hermetic screw compressors
The chillers use hermetic scroll compressors and semi-hermetic screw compressors installed in one, two, three or four refrigeration circuits. The compressors are equipped with an electric crankcase heater to prevent mixing of oil and refrigerant during parking, shut-off valves and an electronic overload protection module. Compressors are located inside an insulated compartment equipped with removable panels for easy access.
Self-cleaning submersible evaporator
ROVER chillers are designed for use in the industrial sector and have a coaxial submersible evaporator. The evaporator is resistant to deposits of impurities in the recycling water system of the enterprise. This type of evaporator is not prone to defrosting with unstable or low water consumption. Integration of the evaporator into the storage tank made it possible to reduce heat losses and reduce the size of the chiller. Chillers with this type of evaporator can operate in an open cooling system of the enterprise, where the technological process is associated with the inevitable loss of water from the system.
Bypass of hot gas in the refrigeration circuit
Bypassing the hot gas in the refrigeration circuit extends the range of operation and the depth of regulation of the chiller performance. This is important when cooling certain specific manufacturing processes.
Highly efficient heat recovery
ROVER chillers may have additional heat exchangers to use the heat taken from the chilled water. This allows you to heat water in the warm season at the same time as producing cold. There are two options for heat recovery: partial 20% when the heat of the superheated refrigerant after the compressor is used, and full 100% when the heat exchanger of the heat exchanger is connected in parallel with the condenser.
