Modular Type Air Cooled Chiller & Heat Pump

Modular Type Air Cooled Chiller & Heat Pump (66kW~502kW)
Air to Water Chiller & Heat Pump
Air Cooled Scroll Chiller & Heat Pump


Part 1: Capacity 66kW~130kW
Sendo Modular Chillers adopt V shape air side heat exchanger, shell & tube type water side heat exchanger and scroll compressors. The master module (Model 65, 90, 100, 130) can work independently or together with up to 16 slave modules, capacity from 66kW to 2080kW.


* Panels can be ordered in either white or dark grey colors

Features

Intelligent Air Volume Regulation
The shared duct system is adopted to greatly expand the operating range. The single module chiller can automatically increase or reduce fans to achieve optimal matching between air volume & load and deliver outstanding performance.

Intelligent Energy Regulation Technology
High performance multiscroll compressors designed for best energy efficiency year round.

Intelligent Defrosting Technology
The control system can determine whether defrosting is necessary according to the ambient temperature in heating mode & evaporating temperature & running time, when defrosting conditions are met, the unit will automatically activate the defrosting program to complete defrosting within a short time and provide heating operation efficiency up to over 90%.

Back-up Functions
In a combination system, if one module failed, other modules can be back-up instead of the failed one for continuing operation.

Alternative Cycle Duty Operation
In one combination module, all slave units operate as alternative in cycle duty to keep equal running time, realize higher stability, better reliability and longer lifespan.


Components

- Hermetic scroll compressor

Famous brand 3-phase scroll type compressor, with built-in thermal overload cut-out and crankcase heater, mounted on rubber vibration dampers.

-
V Shaped condenser
The condenser built with seamless copper tubes mechanically expanded into blue hydrophilic aluminum fins.

- Axial fan
External rotor type axial fans, equipped with direct drive motors, low noise 8 poles, protection level IP54, provided with a protective outlet grille.

- Shell & Tube heat exchanger
Evaporator built with high efficiency shell & tube type heat exchanger, factory insulated with flexible close cell material.


- High precision electronic expansion valve optional
EXV for more precisely flow control. Fast respond resulting in higher efficiency and improved reliability.

- Multiple protection
Electric box consists of breakers and contactors for compressors & condenser fan motors, phase sequence relay and other necessary protection devices for the main components. All electric parts are Schneider Electric brand.

- Built-in hydronic module optional
The modules are fully integrated (Expansion tank, water circulating pump and water flow switch). It saves you much installation space and cost.



Part 2: Capacity 165kW~502kW
Big Size, Large Capacity Air Cooled Scroll Chiller



Features

Modular design
The scroll chiller adopts modular design. Each microcomputer controller of the unit reserves the interface for connecting the combined control module, networking control between units can be implemented by cable connection and simple master-slave settings.

Convenient installation and Lowest total cost of ownership
No need equipment rooms and cooling tower, low initial investment.
Water pipe of the water side heat exchanger has been equipped with the water flow switch, the unit comes with the startup & control cabinet and has been filled with refrigerant before delivery. Each unit was extensively tested to verify its operational reliability, the chiller can be placed in service after being connected with power supply and water supply during field installation.

Components

- Hermetic scroll compressor
Hermetic scroll compressor for the whole range, each compressor is equipped with a crankcase heater and a thermal overload cut-out.

- Condenser & Axial fan
The condenser built with seamless copper tubes mechanically expanded into blue hydrophilic aluminum fins. External rotor type axial fans, equipped with 3 phase direct drive motors, low noise 8 poles, protection level IP54, provided with a protective outlet grille.

- Shell & Tube evaporator
Evaporator built with high efficiency shell & tube type heat exchanger, factory insulated with flexible close cell material. Scroll chiller adopts the new helical baffle design to avoid the rectangular place of water dead zone, greatly improve the heat exchange efficiency.

- Refrigerant valves


- Electric parts
Electric panel consists of breakers and contactors for compressors & condenser fan motors, phase sequence relay and other necessary protection devices for the main components. All electric parts are Schneider Electric brand.

Option
