Commercial Roof Top Cabinet Air Conditioner

Commercial Roof Top Cabinet Air Conditioner SENDO is a professional manufacturer of quality air conditioning products. Sendo could supply most products in HVAC field, such as Rooftop Packaged Unit, Split Commercial Unit, Air Cooled Water Chiller, Water Cooled Water Chiller, Chilled Water Air Handling Unit and Fan Coil Unit etc. Sendo also supplies made-to-measure HVAC solutions. We engineer and manufacture Air Conditioner to suit the building design and application. Rooftop Packaged Unit Features 1. Convenient for unit selection - Colour selection The color can be ordered (OEM) in either white or grey. - Wide cooling capacity range There is a large production line of packaged units, with capacities ranging from 3Ton to 110Ton (12kW to 392kW) at nominal conditions. - Panels selection Panels can be constructed of galvanized steel coated (Standard) or Panels are double-skin with injection of high density polyurethane. - Optional accessories • Inverter Scroll compressors • EC Plug-Fans • Tropical climate T3 condition • Economizer/Free cooling with return air, fresh air dampers and fresh air hood • Heat recovery (Plate type heat recovery & Wheel type heat recovery optional) • Additional water heating coil or electric heater for heating or dehumidification • Optional supply / return air configuration (Side/Top/Bottom) • Optional high level filter (G4 panel type filter, F8 bag type filer and H13 HEPA filter etc) • Optional Golden condenser & evaporator for some area need special anti-corrosion • Optional precision temperature & humidity control • 100% Full fresh air • High external pressure, long air supply distance 2. Outstanding reliability - Economy Some models feature the flexibility and economy of 2~4 stages operation. Compressors are progressively switched on only as they are needed. This has the added advantage of lowering start-up current. - Durable construction • Standard cabinets are constructed from high grade galvanized steel with polyester powder coated, they are completely weatherized for outdoor installation. • Coils are manufactured from seamless copper tubes mechanically expanded into hydrophilic aluminum fins, they are tested under 450 Psi at the factory to avoid leakage. They also undergo dry chemical cleaning after manufacturing for optimum system cleanness. • External fasteners are stainless steel or galvanized type. Corrosion resistant drain trays are also included. • All units are tested at the factory to make sure no leakage and provide reliable start up. - Reliable scroll compressor High efficiency scroll compressor for the whole range, with built-in thermal overload cut-out and crankcase heater. Famous brand compressor: More reliable. - Multi-protection design • Electric panel consists of breakers and contactors for compressors, condenser & evaporator fan motors, phase sequence relay and other necessary protection devices for the main components. • Main power supply breaker is optional. 3. Quieter operation • Compressors and low noise Supply fan are mounted on rubber vibration dampers. • Wave type acoustic Insulation for compressor section, thermal insulation for coil and fan section. 4. Easy installation & maintenance • All units are factory assembled, internally wired, fully charged refrigerant. • The Rooftops has provisions for forklift and crane lifting. On arrival to the job site they are ready to be lifted to their operating position through the lifting supports available on the units. Only connect the wires of power supply, and no need to connect any signal wires. • Quick release

Pipeline Four-Circuit Ball Cleaning Device with Electric Power

Product Description End Cap Automatic Ball Cleaning Device Our proprietary end-cover self-cleaning rubber ball system combines hydraulic dynamics, PLC automation, and mechanical scrubbing for continuous online cleaning of condenser tubes. Pre-assembled for factory integration, it requires zero on-site installation. Cooling Water Velocity 1-3 m/s System Pressure 1.0/1.6/2.5 MPa Power Supply DC24V / AC 110-240V, 50/60 Hz Rated Power ≤50 W Pressure Drop ≤5 kPa Operating Noise <70 dB(A) Environment: 4-60°C 20-95% RH Maintenance Access ≥600 mm Ball Injection Time ≤5 s Ball Recovery Rate 100% Tube-End Automatic Ball Cleaning Device Optimized from end-cover design with structural simplification by removing caps. Direct integration into HVAC unit water pipes eliminates floor space and additional installation work. Cooling Water Velocity 1-3 m/s System Pressure 1.0/1.6/2.5 MPa Power Supply DC24V / AC 110-240V, 50/60 Hz Power Consumption 50 W Pressure Drop ≤5 kPa Operating Noise <70 dB(A) Environment 4-60°C, 20-95% RH Maintenance Clearance ≥600 mm (pipe sides) Ball Injection Time <5 s Ball Recovery Rate 100% (lab-tested) Piped Four-Pass Ball Cleaning System This device utilizes genuine German-made natural sponge balls (slightly larger than the inner diameter of condenser copper tubes) to maintain tube cleanliness through timed ball injection and recovery cycles. Cooling Water Velocity 1-3 m/s System Pressure 1.0/1.6/2.5 MPa Ball Transfer Pump Flow Rate 210 L/min Pump Head Pump Head Ball Injection Time <3 s Operating Noise <70 dB(A) Power Supply 3Φ-380/400/415V-50Hz Installed Power 2 kW Running Power 1.0 kW Connection Port DN50 Piped Dual-Pass Ball Cleaning System Gravity-based ball storage with fail-safe valve control. Recirculation driven by high-head pumps enables closed-loop scale removal. Dual filtration ensures debris separation during cycling. Cooling Water Velocity 1-3 m/s System Pressure 1.0/1.6 MPa Ball Transfer Pump Flow 250 L/min Pump Head 19.5 m Ball Injection Time <3 s Operating Noise <70 dB(A) Power Supply 3Φ-380/400/415V-50Hz Installed Power 2 kW Running Consumption 1.5 kW Connection Port DN50 Self-Cleaning Ball Collector Triple-mode operation via worm gear adjustment. Reverse-flushing design eliminates debris accumulation. Zero-resistance state reduces energy loss during inactive periCooling Water Velocityods.
