1 Product Overview
MRSW single skin ceiling air handling unit is water-cooled ceiling concealed HVAC terminal, split into two full lines: Duct supply model (MRSWXXF) & spherical jet blowout model (MRSWXXS). Airflow covers 2000~15000 m³/h to meet all commercial & industrial constant temperature projects.
Duct version connects rectangular ventilation duct to distribute cold/warm air evenly, ideal for hotels, offices and labs with ceiling duct layout. Jet version equips adjustable spherical nozzles without air duct installation, maximum air supply distance up to 30 meters, specially designed for large open spaces such as airport, exhibition hall, factory and shopping mall.
The unit adopts anti-cold bridge single galvanized cabinet, full-length condensate drain tray and low-noise centrifugal fan. Optional coil, humidifier, air purification and intelligent thermostat modules are available. Ceiling suspension design saves floor space. 380V industrial motor as standard, 220V single-phase power optional, compatible with fresh air, return air and heating-cooling combined HVAC systems.

4 Differentiated Features Of Two Models
1 Duct Supply Type MRSWXXF
Traditional side rectangular air inlet & outlet for ventilation duct connection, multiple external static pressure grades for short/long air duct projects. Graded dimensions: small airflow for guest rooms & offices, large airflow for whole-floor office buildings. Compatible with primary & medium efficiency filter sections to precisely regulate indoor temp & humidity, perfect enclosed buildings requiring uniform air distribution.
2 Spherical Jet Type MRSWXXS
Multiple adjustable spherical jet nozzles on front panel, no air duct needed to save pipeline construction cost. Max air throwing distance reaches 30m with adjustable vertical & horizontal angle. Single unit covers large area for high workshops, waiting halls and exhibition centers, easier installation & maintenance.
5 Eight Core Product Advantages
Anti-Cold Bridge Low-Noise Cabinet
Integrated PE insulation layer inside single galvanized shell, water-absorption free, excellent heat & sound insulation to stop surface condensation; low running noise suitable for noise-sensitive commercial sites.
Full-Cover Non-Leakage Drain Tray
Extended one-piece condensate tray fully covers coil and fan section. Equipped with standard water trap to avoid dripping damage to ceiling decoration during operation or shutdown.
High Efficiency Copper-Aluminum Heat Coil
Mechanically expanded process ensures tight fit between copper tube and aluminum fin for superior heat exchange. Two options: 4-row standard coil & 6-row high-density coil, matching high-temp workshops and low-temp labs respectively.
Low-Noise Maintenance-Free Fan System
Fan passes dual dynamic & static balance test with tiny vibration; motor bearings need no lubrication for whole service life, cutting regular maintenance labor cost.
Dual Power & Multiple ESP Options
Full series supports 220V single phase & 380V three-phase power; various external static pressure grades to fit short or long air duct layouts.
Customizable Optional Functional Modules
Wet film humidifier (80% saturation efficiency), aluminum mesh / electrostatic / photocatalyst air disinfection filters are optional. Match intelligent thermostat to auto switch water valve and save cooling water energy.
Concealed Ceiling Mount To Save Space
Slim suspended structure with standard hoist holes, fully hidden above ceiling without occupying ground space, maintaining building decoration appearance.
Custom Left/Right Pipe Layout
Water pipe connection customizable to left or right side according to on-site pipeline layout, simplifying construction pipeline arrangement.
6 Optional Functional Components Introduction
Wet Film Humidifier
Natural water evaporation humidification, saturation efficiency up to 80%, compact & stable operation for labs and exhibition halls requiring constant humidity.
Air Purification & Sterilization Modules
Aluminum mesh filter: intercept oil fume & large dust particles, washable and reusable;
Electrostatic purifier: absorb dust, bacteria and virus via high voltage multi-stage filtration;
Photocatalyst UV unit: restrain coil mold, decompose formaldehyde & toluene without secondary pollution.
Intelligent Temperature Control System
Equipped with temperature sensor and electric water valve, automatically cut water circuit once indoor temp reaches set value to reduce system power consumption, support fault alarm & mode memory.
Differential Pressure Switch
Monitor filter blockage pressure in real time, remind regular cleaning to guarantee stable airflow.
7 Standard Installation Instructions
Suspension Fixing: Use matched hangers through 4 × Φ15 hoist holes to bear full unit weight;
Drainage Rule: Condensate pipe must install water trap with height ≥ max unit negative pressure +20mm to prevent air backflow and poor drainage;
Pipe Distinction: Facing air outlet, water pipe on left = L layout, right = R layout, confirm before order;
Electrical Matching: Client prepare control cabinet with overload, short circuit & overheat protection. Y wiring for motor ≤3kW, Delta wiring for 3~11kW motor.
8 Main Application Scenarios
Duct Model MRSWXXF
Star hotel guest rooms, office spaces, research labs, small retail shops, hospital wards, medium meeting rooms, uniform air distribution via ventilation duct.
Jet Model MRSWXXS
Airport terminals, railway waiting halls, large exhibition centers, shopping malls, high production workshops, warehouses, hotel lobbies and other large open spaces without air ducts.
9 Combined HVAC System Solution
The unit can cooperate with fresh air handling unit & fan coil to form all-fresh-air water air conditioning composite system with two supply modes:
Mode A: Treated fresh air delivered directly into room;
Mode B: Fresh air mixed inside ceiling AHU then distributed to indoor zones;
The integrated system synchronously controls temperature, humidity and air cleanliness, widely adopted in high-end commercial complexes.
