Dunham Bush chiller unit

Dunham Bush was founded in 1894. In the 1960s, Dunham Bush revolutionized the field of HVAC by introducing screw technology. Due to its high efficiency and reliability, Dunham Bush's compressors are often imitated but unparalleled. To this day, the company still holds 48 world patents, including fully enclosed screw technology.

Cold (Hot) Water Series

Dunham Bush's centrifugal compressor and water-cooled screw compressor technology was born at the Harrisonburg R&D center in Dunham Bush, USA. Since the 1960s, it has undergone nearly half a century of continuous innovation and improvement. Dunham Bush centrifugal products have covered multiple series such as single head, dual head, two-stage centrifugal, magnetic levitation, high-speed direct connection, etc. The water-cooled screw products have formed multiple series such as vertical full seal, vertical semi seal, horizontal semi seal, etc., equipped with star delta start, solid-state soft start, variable frequency start, medium and high pressure drop start and other starting methods, combined with full liquid and falling film evaporators, flexibly applicable to conventional refrigeration, heat pumps, heat recovery, ice storage and other fields. They are widely used in various occasions such as regional refrigeration and heating, urban complexes, commercial centers, airports, rail transit, sports venues, data centers and process cooling, meeting customers' needs for high performance, high efficiency, energy conservation and environmental protection, and comprehensively assisting in the construction of green cities.

Air cooled (cold) hot water series

Dunham Bush developed the world's first vertical fully enclosed screw compressor in the 1980s, and then creatively applied the vertical fully enclosed screw compressor to air-cooled products, creating a new application of Dunham Bush air-cooled vertical fully enclosed screw units. After more than 20 years of continuous innovation and improvement, Dunham Bush now has the industry's most efficient, stable, and reliable air-cooled screw units, as well as a wide range of cooling capacity. So far, Dunham Bush's air-cooled screw products have different choices such as single cooling, heat pumps, heat recovery, high efficiency, ultra high efficiency, as well as variable frequency, natural cooling, falling film evaporative condensers, etc. These products are widely used in various occasions such as regional cooling and heating, urban complexes, commercial centers, airports, rail transit, sports venues, data centers, and process cooling, meeting customers' needs for high performance, energy efficiency, energy conservation, and environmental protection, and fully supporting the construction of green cities.

Unit type air conditioner series

The Dunham Bush modular air conditioning unit has a compact structure, easy installation, and convenient maintenance, which can meet the comfort needs of various environments. The Dunham Bush modular air conditioning units include MSACC (HP) air-cooled split air conditioning units, DCV DC variable frequency multi split units, DBV-W water source DC variable frequency multi split units, and DWCP water-cooled cabinet air conditioning units. They have a compact structure, reasonable layout, and easy maintenance, and can be widely used in residential buildings such as apartments and villas, as well as small commercial and industrial buildings such as offices, shops, restaurants, and factories.

Air side products

Dunham Bush air side products are centralized air conditioning units, air handling units, and fan coil units designed based on rich design and production experience to meet temperature control, humidity control, air purification, and improve air quality in various occasions. The Dunham Bush group terminal air conditioning unit has the characteristics of beautiful appearance, compact structure, easy installation and maintenance, good overall rigidity, and low air leakage rate. It is widely used in industrial fields such as power, chemical, machinery, electronics, pharmaceuticals, airports, subways, sports stadiums, theaters, museums, hotels, office buildings, commercial real estate, etc. Public centralized air conditioning units can provide more than 30 functional segments such as filtration, cooling, heating, humidification, noise reduction, and heat recovery according to user requirements.

Water source heat pump

Water ground source heat pump utilizes solar and geothermal energy absorbed from shallow water sources (such as groundwater, rivers, and lakes) and soil sources on the Earth's surface, and adopts the principle of heat pump to create an efficient and energy-saving air conditioning system that can provide both heating and cooling. Geothermal energy is used as a heat source for heat pump heating in winter and a cold source for cooling in summer. That is, in winter, the heat in geothermal energy is extracted, the temperature is increased, and then supplied to indoor heating; In summer, extract indoor heat and release it into geothermal energy.

Shanghai Yuko sells Dunham Bush chillers, providing a full range of units including central air conditioning, heating products, industrial refrigeration, and more.
