R32 150kW & 180kW Modular Chiller / Heat Pump

The 150kW and 180kW e-Series modular chillers allow for up to six individual units to be connected together to provide a system capacity up to 1,080kW. Available as a cooling only or heat pump version, the e-Series is suitable for both comfort and process cooling applications.

A: High efficiency inverter compressors
The multiple advanced DC inverter-driven scroll compressors incorporated within each module allows for an operating capacity range of 8% to 100% for each module.

B: Four independent cooling circuits
Each compressor has its own refrigeration circuit and shares a twinned plate heat exchanger all located within the module. By modulating the evaporating temperature individually, overall system efficiency can increase by an additional 3.9%, compared to single evaporating refrigeration cycles.

C: Fan inverter control
Each refrigerant circuit has separately controlled, inverter-driven DC fans, allowing for more precise control to save energy and optimise system efficiency.

D: Y-shaped high performance compact air heat exchangers
The use of high performance, compact heat exchangers allows for a greater surface area whilst also keeping the units much narrower than conventional chillers.

The e-Series R32 range coils are equipped with a zinc coating, offering a high level of corrosion protection.

E: Fans
The fan blades have improved airflow characteristics and a newly designed trailing edge that suppresses air turbulence to increase efficiency and reduce noise levels.

F: Optional Internal header pipe
The internal header pipes simplify design, installation and maintenance and makes the e-series range modular and suitable for almost any situation.

G: Digital indicator
A dedicated digital indicator inside the PCB displays high pressure, low pressure, water inlet temperature, water outlet temperature, error codes etc., thereby aiding service and maintenance.

Unique Y-shaped structure

When multiple modules are connected together, the shape of the structure allows for efficient airflow across all air sourced coils.

Four Independent Refrigerant Circuits

Reduced impact on the environment by using R32 refrigerant

R32 has a global warming potential (GWP) one third that of conventional R410A refrigerant. The use of the R32-compatible compressor and flat tube heat exchanger allows for 68% reduction in refrigerant volume and approximately 89% reduction in CO2 equivalent in cooling only models.

R32-compatible high-efficiency inverter compressor

Each unit has four high-efficiency R32-compatible inverter compressors. Compared to R410A, R32 has low pressure loss, contributing to better operation efficiency. The inverter compressor automatically controls the compressor frequencies based on various air-conditioning conditions such as outside air temperature and changes in load, helping to achieve higher seasonal efficiency.

Optimum frequency control for further energy saving

When multiple modules are connected, the frequency of each inverter compressor is controlled during operation to increase the overall module efficiency. This control can be implemented by simply using the unique M-NET control, without the need for any other on-site design.

* The following is an example of operation.

Wide Operating Range

Low Noise Levels

e-Series Coastal Protection Models

While the standard e-Series models come with excellent corrosion resistance, the Coastal Protection e-Series models go a step further by treating external panels and other key elements to a higher paint specification, providing further protection from aggressive salt environments.

Improved Efficiency Compared to R410A e-Series Models

19.4% improved annualised efficiency
