Combined Unit

Combined Unit (deck combined air-conditioning unit) is an integrated air-conditioning equipment specially designed for ship decks and open-air environments. It integrates refrigeration, heating, dehumidification, ventilation, and air filtration. It adopts a fully enclosed waterproof and anti-corrosion structure and can be directly installed in open places such as decks and offshore platforms without the need for additional machine rooms.

Different from ordinary cabin air conditioners, the Combined Unit is specially designed for harsh working conditions such as high salt spray, strong winds and waves, and wide temperature ranges in the ocean. It has IP54/IP56 protection level, marine-grade anti-corrosion coating, anti-vibration and anti-sway structure and other features. Suitable for crew living areas, bridges, control rooms, emergency generator rooms and other areas.

• Railway transportation: signaling equipment rooms, traction substations, outdoor maintenance rooms along the railway line
• Electric power substation outdoor control room, wind turbine tower, photovoltaic power station inverter room
• Warehousing and logistics outdoor sorting center, container yard control room, cold chain logistics equipment room.

1. All structural air conditioning units should be installed on a level foundation.
2. Sufficient space should be left around the unit, especially on the side of the piping and the access door to the fan and motor, to facilitate daily inspection and periodic maintenance.
3. A water seal must be connected to the condensate outlet before connecting it to the external piping.
4. When connecting the inlet and outlet pipes of the coil, apply force evenly and avoid excessive force to prevent damage to the coil.
5. The standard power supply for the air conditioning unit is a three-phase five-wire, 380V, 50Hz AC power supply. Before connecting the power supply to the unit, check whether the voltage meets the requirements, whether there is a missing phase, and whether the three phases are balanced. After connecting the power supply, start the motor briefly to check whether the fan rotation is correct.
6. The air conditioning unit motor should be connected to a power supply with overload protection.
7. A flexible connection should be used between the air conditioning unit and the external ductwork to avoid the transmission of vibration.
8. Ensure that the exhaust air from the outdoor unit does not flow back (i.e., prevent exhaust short circuits) and that the unit's air outlet is unobstructed.
9. The outdoor unit's installation location must be free from the influence of garbage, oil, and corrosive gases.

Compared to ordinary industrial air conditioners, the Hisurp Combined Unit offers significant advantages: It features IP54/IP56 high protection ratings and an industrial-grade anti-corrosion coating (salt spray test ≥1000 hours), providing rain, dust, and corrosion resistance, making it suitable for harsh outdoor environments such as ports, mines, and chemical plants; its vibration-resistant compressor and flexible piping are specifically designed for vibration conditions; it integrates cooling, heating, dehumidification, and ventilation into a single unit, simplifying system configuration; it supports flexible options for air cooling, freshwater cooling, and direct seawater cooling to meet diverse needs; equipped with a DC inverter and EC fan, it achieves energy savings of over 30% and temperature control accuracy of ±0.5℃. With over 20 years of technological expertise, we offer a 2-year warranty, minimum order quantity of 1 unit, OEM customization, 24-hour global service, and CE and RoHS certifications. Choosing Hisurp means choosing professional assurance for industrial outdoor air conditioning.

Unlike ordinary industrial air conditioners, the Combined Unit is specifically designed for harsh outdoor conditions such as high salt spray, strong winds and sandstorms, wide temperature ranges, and rain and snow corrosion. It features an industrial-grade anti-corrosion coating, vibration- and shock-resistant structure, and wide-temperature operation capability. Suitable for industrial locations requiring independent air conditioning, such as outdoor control rooms, mobile equipment cabs, electrical rooms, and equipment rooms, it provides users with an efficient, reliable, and compact outdoor temperature control solution.
