Main Products
Super Green CO2 Refrigeration Unit
The unit is friendly to the environment and energy-efficient.
Super Green is a new refrigeration unit that uses CO2 as the refrigerant. CO2 refrigeration units offer many advantages.

<Advantages of Super Green>
Environmental friendliness: No adverse effect on global warming because of its natural refrigerant, zero ozone depletion potential, and only one global warming potential
Safety: Achieves a high level of safety due to being tasteless, odorless, and nontoxic
Economical: Saves 20-30% energy compared to CFC R22
BCP: The air-cooled system uses no water, making it a powerful tool for BCP and business continuity in the event of a disaster
Outside of regulation: Not subject to the Fluorocarbon Emission Control Law and therefore will remain unregulated in the future 
Versatility: Wide range of cooling temperatures from +10 to -43 degrees Celsius

<Applications of Super Green>
Equivalent to Class F refrigerator-freezers and Class C warehouses
Chilling for freezers in food factories
CO2 brine chiller for cooling ice plants
For the cooling process in margarine production
The CO2 produced by the brewery can be cooled and used in a brine chiller for liquefaction
BluAstrum Ammonia Chiller
This chiller achieves both environmental friendliness and large-scale cooling.
Using ammonia as its refrigerant, BluAstrum is a large chiller that is environmentally friendly while realizing large-scale cooling. Suitable for the cooling process of food factories and chemical plants and for air conditioning in large spaces.

<Advantages of BluAstrum>
High efficiency
Cooling from -15 to +18 degrees Celsius
Seven models are available from 400-1800 kW
Environmental friendliness: Its natural refrigerant causes no adverse effect on global warming. Zero ozone depletion potential and zero global warming potential
Safety: Realized a high degree of safety by welding joints wherever possible. An ammonia abatement device is integrated into the unit. The refrigerant volume filled is small.
Compact size: Minimizes the space needed for installation
Economical: Achieves high COP with an annual COP of 8.4
Industrial Refrigeration Unit
Made-to-order units built according to customers’ requests.
We manufacture refrigeration units based on our customers’ requests and applications, such as the use in chemical plants, food plants, automobile plants, power plants, and laboratories on a made-to-order basis.

<Advantages of Industrial Refrigeration Unit>
Wide range of cooling temperatures from -50°C to +20°C
Cooling capacity: Wide range of cooling capacities from 10 kW to 2,000 kW
Various operation patterns: Multiple temperature zone cooling
Special operation: 0% operation (no-load operation) and other special operating conditions
Explosion-proof: Suitable for explosion-proof specifications in petrochemical plants, etc.
Seismic: Special seismic features are also available.
Enegeo Geothermal Heat Pump
Highly efficient and stable air conditioning using geothermal heat.
Heats and cools the air with small power consumption using geothermal heat. It has increasingly been adopted in many facilities, especially in cold regions.

<Advantages of Enegeo>
Since it uses geothermal heat, heating operation is stable even in cold regions, and cooling operation is highly efficient in summer (high energy-saving performance; COP energy saving rated 5.4-5.8)
High COP even at partial load due to inverter control
(COP* = 5.4 to 5.8 for 100% cooling operation, COP = 8.0 for partial load cooling operation, COP = 4.3 to 4.5 for 100% heating operation, COP = 6.4 for partial load heating operation)
A single unit can heat and cool a medium-sized (200 m2 to 2000 m2) or larger facility.
A semi-hermetic reciprocating compressor is used. Achieves reliability, high efficiency, and high output at the same time.
5 models are available, including 20 kW, 50 kW, 100 kW, 150 kW, and 200 kW
Durability: Operable even at -10°C in source water (stable operation even at low temperatures)
Low noise and low vibration design
Heat Pumps for Air Conditioning
Ideal for heating and cooling large spaces, such as municipal government buildings, hospitals, concert halls, museums, conference halls, shopping centers, and airport facilities.

<Heat Pumps of Various Types>
Air-Source Heat Pump
A standard heat pump for air conditioning. It realizes highly efficient heating and cooling with low power consumption by using atmospheric heat.

Water Source Heat Pump
A heat pump that uses heat from underground water and river water. Its use of water, whose temperature remains constant both in summer and winter, as a heat source realizes highly efficient stable cooling and heating operation. 

Heat Recovery Heat Pump
Simultaneous operation for cooling and heating. This air source/heat recovery heat pump can extract cold and hot water simultaneously.

Ice Thermal Storage System
The system uses inexpensive nighttime electricity effectively. By installing it with a heat pump, you can reduce the electricity bill and make do with a small capacity refrigerator. 

Warm-Water Thermal Storage System
High-power heating even on winter mornings. We have delivered many units as our proprietary system.
Other Products
Refrigeration Components
Screw compressors for all types of refrigerants and a wide range of cooling temperatures.

Solar Water Heater
Reduces energy costs by producing hot water from solar radiation even in winter. It has numerous advantages such as environmental friendliness, high efficiency, high quality, and durability.

Cogeneration System
Generates electricity with a gas engine and utilizes exhaust heat. The gas engine drives the generator to generate electricity while simultaneously recovering heat from the exhaust gas and engine cooling water, thereby producing steam and hot water.

Showcases for Supermarkets
These are refrigerator showcases offered by Freor in Europe. The showcase incorporates a compressor that uses R290 (propane) as a refrigerant, which is environmentally friendly in terms of preventing global warming.
