1. Based on its leading-edge design for air cooled and heat pump
units in Europe as well as the wide use of its air-cooled units in
China, EK has launched this series of innovative modular air-cooled
water chiller (heat pump) units. The full-load COP of this series
is higher than that the energy saving product certification
2. Each modular unit has two power gears. When multiple modular
units are combined, there could be many power gears.
Fully-optimized model selection and matching practice ensures that
the units can always save as much energy as possible. When
operating with a partial load (99% of full operation time), the EER
is even 4% higher.
3. With an optional 2-way valve water control feature, the unit can
send out signals to turn off corresponding chilled water valves.
This enables automatic flow control for pumps in line with the
transducer, which helps save more energy.
4. The unit features modular design and starts up in steps to ease
the shock on the power grid caused by startup current.
5. The unit has undergone strict and long-duration tests according
to the most stringent standards, and can work reliably to providing
cooling when the ambient temperature is as high as 48℃ and heating
when the ambient temperature is as low as -10℃.
6. The system features built-in high/low pressure protection,
cooling freezing protection, winter freezing protection, compressor
overload protection and water pressure-drop switch etc. to maximize
the safety of the unit.
7. The unit uses a 500-step PMV electronic expansion valve for
precise PID control, dynamic and real-time adjustment of the
cooling system, and higher-precision water temperature control.
This helps optimize the performance of each and every part of the
system. The unit can work reliably under any load and automatically
adapt to changing ambient temperatures, completely eliminating
cooling system vibration.
8. The entire unit features vibration isolation design and multiple
noise reduction processes. Both noise level and vibration level of
the unit take the lead in the industry thanks to its name-brand
quite hermetic volute Compressors and two-gear quiet fans. The
noise level of the unit is significantly reduced using professional
noise reduction practices, such as comparing, choosing and
improving fans, motors, structures and pipelines based on noise
spectrum analysis results.
9. Innovative smart silencing mode can automatically adjust the fan
rev (high/low) according to outdoor temperature and the operation
status of the unit. This makes the unit even quieter in operation
10. The unit needs no additional equipment room, and can be mounted
on the floor, building roof, etc. Modular design makes each unit
small in dimension and suitable for transportation by cargo
elevator, thus saving hoist cost during construction. The unit can
also be installed step by step to shorten the construction period.
11. Each unit has a separate refrigerant circuit. This reduces the
probability of refrigerant leakage which could damage the
12. The unit uses a micro-computer controller with a large LCD
screen to facilitate operation. Each controller can control and
dynamically monitor the operation of up to 16 units. This
facilitates centralized management.
