Note:
1. Working conditions for nominal heating capacity: outdoor dry/web bulb temperature at 20°C/15°C, inlet water temperature at 40°C, outlet water 45°C.
2. Please be kindly reminded that further modification(s) to the parameters herein for customer need will not be reported separately.
3. Notes on the power cord: The electrical parameters hereinabove applies to the base unit. Reliable connections shall be maintained. There shall be contact between any wire and refrigerant pipelines and/or heat generating components such as compressors and fans.
Multiple power gears
The EKAH has two power gears or more when multiple modular units are combined (i.e.: 8 sets of EKAH offers 16 power gears). The gear shift is controlled by electronic devices, reducing starting current to the power grid, with improved efficiency.
High performance
The EKAH series combines advanced technologies and world-class components by sophisticated testing so that compatibility will be guaranteed. Low noise level is achieved with fully hermetic volute compressor and low noise fan. Outstanding COP value is made possible by high performance pervolute compressor, precise flow control system with electronic expansion valve, and infinitely variable water flow control. When operating with a partial load, the COP will be even higher.
Easy control
The Unit is controlled by electronic devices which offer both centralized and individual access. The controllers have high noise immunity, allowing them to control the Units from as far as 1000 meters. Controller Error codes provides convenience for repair works.
Simple installation
The Unit is designed for maximum simplicity in installation. The cooling system are pre-fabricated before delivery, hence customers will not need to perform any copper tube connect or refrigerant refill. All that is required is to properly install the Unit, connect the water in/outlets of the water system to the designated equipments, check if the water and pipes of the water pump is clean, fill in water, and turn
on the power to run.
Defrosting
Automatic defrosting is performed by controllers based on operation hours and the temperature of heat exchangers.
Safe Operation Control
The high/low-pressure protection will stop Unit operation under excessive high air discharge or low suction pressure. Air discharge temperature protection will prevent the temperature of air discharged from getting too high. Water overheat protection will make sure the pressure of air discharged will not exceed upper bounds. Antifreeze function protects water pipes and water side heat exchangers from cracking under extremely low ambient temperature (effective when main power supply is connected and under water heat mode).
Environmental durability
The casing of the Unit is made of phosphated zinc-plated steel plates coated with polyester powder painting, making them highly resistance to the elementals. Because of the fine design, the Unit does not require special housing nor large area, and could be placed almost anywhere in the front or back of the house, or the building top and balcony. Extreme temperature will only have minimized impact on its performance.
Convenient maintenance
All parts could be accessed by just removing the side or front panel, greatly simplifying its repair and maintenance. The controller offers fault diagnosis in case of exceptional shutdown, which helps speeding up troubleshooting.
