YORK 026-41611-001 Motor Actuator

The York YK series is a classic single-stage centrifugal water-cooled chiller unit under the Jungson Control brand. It is a mainstream model for large commercial buildings, industrial processes, and other high-demand refrigeration scenarios. Its core features are as follows:

 1. High-reliability core structure design
Single-stage centrifugal compressor: Fewer moving parts, simple and efficient structure, stable unloading operation in harsh conditions such as hospitals, chemical plants, and oil and gas processing; equipped with long-life design bearings, significantly reducing daily maintenance requirements and failure risks.
Open air-cooled motor: The refrigerant is completely isolated from the motor, preventing catastrophic failures such as motor burnout that could contaminate the entire refrigerant system. It also significantly reduces the insurance cost of large refrigeration equipment and is recognized as a highly safe design within the industry.

2. Efficient and energy-saving performance across all operating conditions
High-efficiency heat exchange system: Utilizes a new generation of enhanced heat exchange copper tubes, optimizing heat exchange on both the water side and the refrigerant side, enhancing efficiency while reducing the rate of pipe fouling; some models are equipped with a drop-film evaporator, further improving energy efficiency while reducing refrigerant charging volume.
- Wide operating range with low energy consumption: Can be adapted to as low as 12.8℃ chilled water temperatures, compared to conventional units, the instantaneous energy consumption can be reduced by up to 50%; equipped with variable frequency drive (VSD), some load conditions can achieve up to 40% energy savings compared to constant-speed units, and the full-load energy efficiency can reach 0.20kW/cold ton, significantly reducing annual operating costs.
Quick start capability: The Quick Start function enables the unit to restart in as short as 45 seconds, quickly reaching the set chilled water temperature, suitable for scenarios with rapid load fluctuations.

3. Intelligent control and expansion capabilities
- Standard OptiView™ control panel: Precise control of chilled water outlet temperature and motor current, real-time monitoring of all system operating parameters, and automatic optimization of unit performance under different operating conditions.
- Rich optional features: OptiSound™ noise reduction control combined with variable frequency technology reduces air turbulence to lower operating noise; ISASecure® certified access management system prevents unauthorized operation risks and ensures control safety of the unit.

4. Environmental friendliness and adaptability flexibility
- Multi-refrigerant compatibility: Native support for R134a environmentally friendly refrigerant, new models are specifically optimized for ultra-low GWP refrigerants R-1234ze, and R-513A, R-515B, etc., can also be selected, and changing refrigerants does not require additional installation space for the unit.
- High customization level: Can be selected with different specifications of heat exchangers, gearboxes, and motor configurations without having to choose a larger machine base for adapting to specific operating conditions, balancing performance and cost.

5. Installation and maintenance convenience, low full-cycle cost
The overall design of the unit is compact, significantly reducing the floor space required for the machine room; installation only requires a small amount of piping and wiring, shortening the installation period. The open motor design allows for motor maintenance without invading the refrigerant system, reducing the workload for daily inspections and major repairs, with strong compatibility of original spare parts, and better overall lifecycle usage and maintenance costs.
