460kW air cooled scroll chiller

Features

 

• Overview

EKAC series air-cooled chiller (heat pump) units are highly reliable, secure and flexible.

This series of units are elaborately designed to be delicate and elegant. In addition, they can support fan coils and air handling units of various specifications and models.

Units of this series are marked for their high efficiency, low noise, user-friendliness, secure operation, easy installation and maintenance etc, and are widely used in factories, stations, hotels, villas, office buildings, top-grade residences etc. Besides, they can also be used in industrial chilling.

• Multi-grade Modulation

EKAC1600 series units feature 4-grade modulation which can be transformed to multi-grade modulations in modular combinations. For example, 16 EKAC1600 units can realize 16 modulation grades with effects very similar to that of stepless modulation. With operation grades controlled electronically, the unit exerts less shock to the power grid and saves more energy.

• Outstanding Performance

EKAC series units feature leading-edge technologies and name-brand accessories which are strictly tested for compatibility. Fully hermetic volute compressor and low-noise fans minimize the operation noise. With efficient volute compressors and precise throttling systems with electronic expansion valves, the units feature high EER and COP, especially at partial workload.

• Easy Control

Units can be controlled individually or together by an electronic controller. The controller is strongly interference proof and can exert control from as far as 1000 meters away. Failures are indicated by error codes displayed on the controller to facilitate troubleshooting.

• Easy Installation

The units are designed to best facilitate installation. The cooling system is made hermetic in the factory. Customers do not need to connect any copper pipe or refill refrigerant. The water system has an inlet connector which is to be connected to the terminal equipment. Having installed the unit as instructed, customers just need to check that water and pump pipes are clean before pumping water and powering on the unit.

• Defrosting

The controller defrosts the unit automatically according to the operation time of the unit and the temperature of the heat exchanger.

• Safety Measures

The cooling system is protected against extreme pressures: discharge pressure will not be too high, nor will inhaling pressure be too low; against extreme discharge temperature: discharge temperature will not be too high; against freezing during cooling operation: when the water temperature is too low, the plate heat exchanger will not freeze up or burst internally; and against low temperature: during cold winter time, the water pipe and plate heat exchanger will not freeze up or burst internally (This feature works only when the system is working in the heating mode with the main power supply turned on).

• Highly Adaptive

The unit shell is made of galvanized, phosphorized steel plate with pure polyester plating to withstand weathering. The unit is reasonably designed to save space. It can be mounted on walls, balconies or the roof, thus eliminating the need for a dedicated equipment room.

The unit is highly adaptive and can operate smoothly in hostile conditions such as extremely high or low temperatures.

• Easy Maintenance

To access and service any part of the unit, you just need to dismantle the side panel or the front panel. When the unit stops working abnormally, the controller prompts the reason to facilitate troubleshooting.
